Good morning, everybody. It's brilliant to be here today, and as usual, I'm joined on the stage by our CFO and the new YouTube sensation, Russell O'Brien, for those of you that watch this video, no doubt. Our leadership team here in the front row, and our chairman here as well, and a number of other Centrica people. So 2025 was a year of significant progress, building further on our journey to make Centrica a stronger, higher-quality business, building on the foundations that we've been laying for growth. We're recycling capital from non-core assets, investing in assets like Sizewell C, Grain LNG, and the Meter Asset Provider, assets that will both grow and stabilize our earnings profile, eliminating downside risks. We're adding long-term value, and we're building future optionality. 2025 showed our resilience and our further improved operational performance, but it also had its challenges.
Conditions remained difficult for Centrica Energy throughout the year, as it did for many, many commodity traders. I'm delighted with what the team delivered in 2025. As always, I'm looking for more, and it's a mark of how far we've come that collectively, we're not satisfied with GBP 200 million of EBITDA from optimization, and collectively, we're not satisfied with more than 11 pence EPS in a difficult year, because our expectations of what Centrica can deliver have fundamentally changed. Over the last five years, we've invested GBP 3 billion, and we've returned around the same amount to shareholders, including increasing the dividend by 22% this year. Balanced capital allocation, reflecting our commitment to growing the business and to rewarding our owners, our shareholders.
We've now bought back a quarter of the company since 2022, at an average price which is well below where we are today. It's in the low GBP 130s. That's real value delivered, and we've decided to pause the buyback for now, as we see incredible value creation opportunities for our shareholders from investing the capital that we've got. Our pipeline is so much richer now than when we started buying back shares in 2022, and some of those opportunities could come through quite soon. But our financial framework hasn't changed, and neither has our discipline. If the projects don't stack up, we won't invest, and surplus capital will always come back to shareholders. Always.
We expect to invest at least another GBP 700 million this year, maybe more, mainly in assets that fundamentally strengthen our portfolio, and we expect to continue investing at about the same rate right through to the end of this decade. And that's what underpins our confidence in delivering GBP 1.7 billion of EBITDA or better by the end of 2028. And it's why we can tell you that we'll continue to grow that beyond 2028 to GBP 2 billion by 2030. Now, both of these numbers include the impact of expected but not yet confirmed extensions to the four existing advanced gas-cooled nuclear power stations into the early 2030s. GBP 2 billion of EBITDA in 2030 would see our EPS more than double over the next 5 years.
But I'm never satisfied, so rest assured that my aim is to do even better than that. By focusing on value, we've made Centrica a much stronger business than it was six years ago. We're running the business as well as we possibly can. We're investing in a disciplined way, and it's the same approach that will deliver the next phase of our growth. We spoke in July about how we saw opportunities to transform Centrica. Now, our transformation program is going well. It's a key part of delivering our full potential. We've made progress anchored in three simple principles, all underpinned by technology. Number one, improving customer experience further. Number two, driving more commercial growth. And number three, continuing to deliver on cost efficiencies. A lot of this benefit will be in the retail business, but there's huge potential across the entire group.
Last year, we delivered net benefits, net benefits of GBP 100 million. Unlike other companies, we're not recording transformation costs in exceptionals. If we had done that, 2025 EPS would have been 2 pence higher. So if another company, it would have been 11.2... 13.2, not 11.2. The program will ramp up this year, and we expect to take another GBP 500 million out of the cost base by the end of the decade, over and above what we've already done, underpinning earnings growth and helping to create new opportunities. Now, AI is a part of that, and it's a huge opportunity for us.
We're working with world-class partners to explore how we can further deploy technology, including AI, but not only AI, to transform our customer service and to reduce costs. I'm going to lay out some of the specific examples of that later. With the opening, I'm going to pass you over now to our CFO, Russell O'Brien, who's going to take you through the numbers.
Thank you. Okay, thanks, Chris, and good morning, everybody. So over the past years, we have reshaped the way we run Centrica, with a focus on three business units: retail, optimization, and infrastructure. And we've taken this opportunity to simplify our reporting, aligning the segments to the way we now run the business. And we've also shifted to EBITDA as our main performance and guidance metric, which is a better measure for the business as we invest in the portfolio and grow. Now, I recognize there are a few moving pieces, so I've put a very funny video explainer on the website, as Chris was mentioning, and some other materials, just so that no one's confused by the resegmentation, and it unpacks everything in a little bit more detail. The main change is splitting Bord Gáis and Centrica Business Solutions into their component parts.
Irish Retail, for example, is now reported alongside the same U.K. activities, Irish Optimization within Centrica Energy. We've also moved our Irish Power assets and our growing meter asset provider into their natural home and infrastructure. Now to the numbers. I'd like to highlight three key points. First, we've reported solid numbers overall in the context of external challenges, demonstrating the resilience of our business. Second, our progress on investing and transformation program gives us more confidence in our medium-term earnings outlook. Third, our balance sheet remains strong, giving us the financial platform to execute. Adjusted EBITDA for the year was GBP 1.4 billion, and adjusted earnings per share was just over 11 pence.
We delivered operating cash flow of over GBP 900 million, while we had a free cash outflow of GBP 200 million after doubling investment to GBP 1.2 billion. After returning over GBP 1 billion to shareholders through the dividends and the buyback, adjusted net cash closed at GBP 1.5 billion. Retail and Optimization delivered almost GBP 800 million of EBITDA, with retail contributing GBP 574 million, broadly flat year-on-year. Within that, U.K. Home Services delivered almost GBP 170 million of EBITDA, and the 7% top-line growth reflected improvements to our commercial propositions and pricing, and it was supported by a razor-sharp focus on costs.
Margins expanded from 4.3% to 6.8%, and we're pleased to have moved out into the profit range we outlined ahead of schedule, and there is still much more to come. Business Supply also delivered a strong result. U.K. Home Energy Supply and Optimization both faced external headwinds and saw EBITDA decline, and I'll come back to both of those areas in a moment. And finally, infrastructure of GBP 728 million of EBITDA was lower due to a combination of asset sales, realized prices, and outages in Q4, offset by a lower-than-expected loss at Rough. As usual, we can find more detail on the business performance in this morning's release. As consumer demands change, competing effectively in the retail market requires efficiency, innovation, and resilience, and we were behind the curve in many of those areas.
But the evidence is clear: we are moving in the right direction. For the first time in over a decade, we grew customer numbers across all of our retail businesses simultaneously, underpinned by the simplification and the use of technology. This includes the migration to Ignition and modernized planning systems and services, unlocking commercial flexibility, deeper customer insights, and cost efficiencies. Those dynamics were key to the improvements in services. Retention is improving, we're building new growth channels, and we're managing margins effectively. But as ever, we are not satisfied. We are still losing customers we shouldn't be losing, and there's more we can do commercially. We want to continue growing our retail customer base, but we won't adopt the pricing behavior we're seeing from some of our competitors. We believe it is unsustainable.
We'll remain nimble, of course, and compete hard, but our primary focus is on delivering value over volume. And with more insight, we're able to identify and focus on those customers who really want our products and services, helping them get better solutions for them and creating more value for Centrica. Home Energy Supply delivered a resilient performance in 2025. As expected, the market continued to pivot towards fixed-price tariffs, which had a dampening effect on margins, and weather was a GBP 80 million headwind through the year in the U.K. Now, on the other side, the Energy Price Guarantee scheme reconciliation saw us record a gain of GBP 42 million related to revenue from prior periods that was not recorded at the time. And the results, as you've seen, benefited from other cost and revenue phasing from earlier periods.
Bad debt remains a challenge, with the latest figures showing over GBP 4 billion of debt past due across the industry. A bad debt charge in U.K. home energy supply increased to around 3% of revenue. Now, we continue to advocate for Ofgem to take more proactive steps to help those who genuinely can't pay and address those who can but choose not to. But in the meantime, we do expect those additional costs we face this year to be recovered in future periods. The ups and downs reflect the essence of the U.K. home energy supply business: short-term volatility offset by through-the-cycle predictability. Since the price cap began in 2019, as you can see, our average margin is 2.3%.
That's above the 1.9% allowed during the first four years of the cap and broadly in line with the allowance since then. Supported by the price cap mechanism, this is a business that generates solid, through-the-cycle, regulated earnings and cash flows. Centrica Energy posted a softer result, primarily driven by gas and power trading. Against that backdrop, we've remained focused on driving long-term value, and GBP 200 million of EBITDA in a tough year is a big step forward from where that business was a few years ago. RETO, our renewable route-to-market business, again performed well. Assets under management grew by 17% to over 19 gigawatts. Centrica Energy is now consistently one of the most innovative, responsive, and commercial partners to asset owners across Europe, strengthening our ability to grow more in this area.
In LNG, the teams have fundamentally transformed the portfolio over the past couple of years. We are now 100% hedged until 2028, and over 80% until 2030. So we've protected any downside and retained valuable physical optionality. Now, we're not satisfied with the absolute performance in gas and power trading, but we do take comfort in strong relative performance. In really difficult markets, the team generated a positive margin and remained consistently disciplined through the year. Consciously reducing risk rather than chasing aggressive positions is a core principle of how we operate. This limits downside, with returns skewed to the upside when markets allow. In the short term, more rational behavior is returning, with gas trading recovering a little bit in the second half.
But events, as we've all seen in the past week, demonstrate the market remains very volatile, and it looks like it'll take some time for them to stabilize. So given all that, we expect Centrica Energy to be below its sustainable EBITDA range for this year. We remain confident, though, in the longer-term outlook, with earnings unsupported by expanding our geographic footprint and capabilities, adding further diversification and growth options to the portfolio. So of course, the challenges we saw last year demonstrate why it's so important to continue building our predictable contracted infrastructure portfolio. In 2025 saw us more than double investment year-over-year, spending almost GBP 400 million at Sizewell C, GBP 200 million in Grain and GBP 225 million in the MAP, which was higher than our target.
After other movements, including decommissioning and disposals, we saw a free cash outflow of GBP 167 million. We returned 1.1 billion to shareholders in 2025, which means we've invested and returned GBP 3.6 billion over the last two years. The balance sheet remains strong, and we expect surplus capital to emerge over time as the business continues to perform. But as we've demonstrated, we keep the balance sheet under close review, and our commitment to maintaining that discipline is unchanged. Now to the outlook this year. Alongside streamlining our segments, we've simplified it, simplified our guidance ranges, but there's no change to the underlying numbers. All we've done is restate on an EBITDA basis.
In 2026, we expect retail to be in its EBITDA range of GBP 500 million-GBP 800 million, and that's after the transformation spend in the year. We currently expect optimization EBITDA to improve somewhat relative to 2025, but remain below the medium-term sustainable range at around GBP 250 million. Assuming the second Spirit Energy disposal completes around the middle of the year, we see GBP 500 million-GBP 650 million as a sensible range for infrastructure, including, importantly, about GBP 175 million from the key regulated and contracted assets. As a reminder, earnings from the Spirit disposal assets will continue to be recorded through the P&L until the transaction completes later this year. We also assume Rough will be around breakeven, driven by a continued focus on optimizing indigenous gas sales and cost discipline.
We expect investment of at least GBP 700 million. This includes transformation, further investment into the MAP and our power assets, including Sizewell C. Today, we've also laid out guidance on interest and tax to help with your modeling, including a structural decline in the effective tax rate as we pivot the portfolio away from highly taxed Spirit Energy earnings. So we're all excited about our transformation program, which has accelerated over recent months and underpins our plan to deliver top-line growth while driving underlying efficiencies through the organization. Our operating cost base is just under GBP 2 billion, including bad debt and depreciation. 3% annual inflation on that is a GBP 300 million pound earnings headwind by 2030. So driving cost efficiency is a both opportunity, is a huge opportunity and a necessity.
And we're ramping up multiple work streams, and we're already taking actions that are making a real difference, which Chris will talk about shortly. In 2025, we reduced OpEx by 3%, net of inflation and cost to achieve over GBP 100 million. Looking forward, we aim to deliver a further GBP 500 million pound reduction in the, by the end of the decade, and we have around half of those savings identified already and are working hard to lock in the remainder. That means we expect our nominal cost base to remain broadly flat by 2030, with efficiencies fully absorbing inflation and the cost of supporting growth. And from what I can see today, there are probably around GBP 600 million of cost to deliver those benefits, around GBP 400 million of OpEx, and a further GBP 200 million of CapEx.
We will be as disciplined in our OpEx investment as we are deploying capital generally. The earnings benefit will come through over time. As Chris says, we'll be transparent about the costs, and we don't expect exceptional charges. We want to give you the tools to assess our performance, and more importantly, we want to ensure our colleagues are fully focused on delivering value. So to summarize, Centrica's performance in 2025 was resilient in the face of some external challenges. The assets we brought into the portfolio over the past year mean we are increasingly confident of being able to maximize sustainable earnings, the foundation of our financial framework. We're successfully balancing rewarding our shareholders with retaining the strength to support our growth ambitions. With that, let me hand back to Chris.
Thanks, Russell. The trends shaping the energy system became ever clearer in 2025. U.K. electricity demand grew for the second year in a row, following many years of decline, and intermittent generation rose to over a third of total supply. Now, looking forward, demand growth will accelerate and renewables penetration will continue to grow. So will the need for zero-carbon baseload electricity, dispatchable backup electricity generation, and electricity storage to keep energy secure and affordable for the households and the businesses that will drive the economic growth the U.K. needs. There's a once-in-a-generation investment cycle underway to meet these growing needs. The challenges of delivering new projects are real. Planning, good connections, supply chains, none of this is easy. Like, a couple of years ago, you could pretty much pick up a gas turbine off the shelf. Today, there's a 5-year waiting list.
So existing capacity will also be needed for much, much longer, and as you can see, the expected proportion of gas-fired electricity generation in the mix in 2040 has almost doubled. That creates huge opportunity for us, and it's why we believe our strategy is the right strategy, focused on the assets that will be needed to support a fair and affordable energy transition, while remaining pragmatic and retaining the flexibility to adapt however the transition progresses. The right strategy is one thing, but it must be coupled with the ability to deliver, and that's way more than about reshaping the portfolio. It's about way more than that. It's about rebuilding a platform that allows us to compete in a rapidly evolving retail market and about building the capability to identify, develop, and operate the infrastructure assets that will define our future.
Now, we've now got the foundation and the transformation program that will help us deliver this next phase, focused on the core areas that I mentioned earlier: customer service, commercial growth, cost efficiency. Transforming customer service is critical to our success. We've made progress improving our digital contact channels, but we're consistently identifying more areas for improvement. Our aim is to reduce contact by at least 30%. Now, it's not that we don't like speaking to our customers. We really do. It's that we want to give them fewer reasons that they have to contact us. We want to use technology to help us make their lives easier and to offer more relevant products and more relevant services. If we achieve that, that will be a significant efficiency gain, but we want even more.
We're also aiming for a further 40% of customer contact being handled through enhanced digital channels, including far more use of AI to support our colleagues. By ramping up the use of technology, we're freeing up time to solve the thorny issues, the really difficult issues for customers, and to drive commercial performance, creating the right jobs in the right places as we grow our business. We're investing in the skills and the capabilities that we need for this future, rewiring how we work to sharpen accountability, to grow expertise, and to help us serve customers far more efficiently. That extends to our central functions. We've reduced headcount there already by around 5%, mainly by eliminating duplicated roles following the restructure of the business. By embedding new, more agile ways of working, we can make our core processes much, much more efficient.
The savings potential from this area alone is well over GBP 100 million a year. Improving commercial performance is still the biggest opportunity that we've got to grow the business. Russell mentioned the success we've seen in retail. There's no magic behind the improvements. They've been driven by focusing on the details of our processes, getting to the root cause of poor performance, and identifying the solutions. Take boiler installations as an example. We've seen decline in profitability there for a year, for years, which was a bit of an issue. But by working to improve each individual step in the process, for example, job pricing, scheduling, we were able to unlock a GBP 20 million profit improvement. That was a key contributor to the better performance and services last year, and we're already moving on to the next target areas.
We're implementing a combined customer lifetime value model across retail so that we can identify opportunities to maximize value across the group. Now, that might mean that we trade off value in one part of the business to secure more value elsewhere. We're happy to do that. The overall group benefit is what matters. This is only possible by having the right people in the right structures with the right data, the same capabilities that are supporting our investment program. Disciplined investment is central to our progress, and it's central to our future growth, driven by the stronger capabilities we've built across our infrastructure businesses, Power under Dave Kirwan, Gas under Martin Scargill, and Spirit Energy focused now on Morecambe Net Zero. Teams with deep technical expertise, proven operational discipline, and a value-focused mindset that creates broader growth options for the company.
In Sizewell C, in Grain LNG, and in the MAP, we're investing in high-quality, long-duration, regulated, and contracted assets that will fundamentally reshape Centrica and deliver critical national infrastructure for the U.K. We're doing a similar thing in Ireland with our peakers. We made our initial contribution to Sizewell C in November. We've got earnings in 2025 relating to Sizewell C, and earnings will grow in a predictable way for the next 15 years. We expect our share of the RAB to grow to around GBP 8 billion by commissioning. That'll be against a net equity investment of around GBP 500 million and project financing of GBP 5 billion. Real value creation with very, very low risk. The MAP is also a real success story. It's hugely outperforming our expectations, the expectations we had when we set the business up.
We installed over a million meters last year, which makes us the fastest-growing MAP in the U.K., and we've now got more than 1.6 million meters on the wall, just around 2 years after we set this business up. The capabilities that we've built are unlocking future growth opportunities, both in the U.K. and overseas. Dan, Gareth, and the team deserve huge credit for what they've achieved, but they don't get any special treatment. Now, we've seen what they can deliver in 2025, I expect even more this year. We're still early in the ownership journey, for example, at Grain, but the value of the asset is clear. Earnings are highly contracted. The importance of the terminal will only increase as the U.K. becomes ever more reliant on imported gas.
I've been delighted to see the strong alignment we've got with ECP, our partners, on the key priorities for the asset, and I'm confident we've got the right team in place to deliver on the full potential of this absolutely critical business. Now, we've got to acknowledge that not everything has gone completely to plan. Commissioning, for example, of our Irish peakers has been delayed, and they're now due around about the middle of this year. Now, that's partly due to grid connection delays, and we've secured a modification to the capacity market contract to compensate for that, mitigating the value impact, but it also reflects missteps that we've made as we build back our construction capability. We're not happy about that, but we have learned valuable lessons, and we're confident that will be applied to future projects. We've not really built big infrastructure for over a decade.
We've also been proactive in managing our portfolio, recycling capital from non-core assets. You saw a recent disposal last month. Portfolio simplification has allowed us to accelerate value, sharpen our strategic focus, and reduce our exposure to commodity price volatility. Collectively, the actions we're taking are fundamentally reshaping our company, steadily shifting our portfolio towards more regulated, more contracted earnings. As Russell laid out, home energy supply has a regulated underpin, while services and B2B both generate more stable cash flows from contracted activities. The trajectory in the existing infrastructure portfolio is very, very clear, and we've got several opportunities that could even accelerate that pivot. The government consultation, which will decide the path forward at Rough, closed yesterday, and we expect a public update hopefully later in the first half.
We're optimistic about the outcome, given the critical importance of gas storage to the U.K.'s energy security, which was acknowledged both in the consultation document and by me so recently. But we remain super focused on the value proposition, and we won't keep Rough open speculatively. We need clarity to justify redevelopment. The government's also due to publish a decision on financial support for nuclear life extensions over the next few months, including the potential for a CFD at Sizewell B to underpin a 20-year asset life extension. These are two very clear opportunities to pivot merchant-exposed assets to regulated exposure and to substantially extend asset lives. Even Centrica Energy has got an element of predictable fee-based earnings and has materially reduced the downside risk in the LNG business, way beyond, I think, what people appreciate.
If you look further ahead, the steps we've taken to expand our organic growth pipeline, for example, our partnership with X-energy and further development opportunities at Grain, allow us to be disciplined, to focus on the most valuable opportunities, and to adapt as the energy transition develops. Our investment focus remains the same: assets that support security of supply, assets with a regulated and contracted underpin where we can add value through optimization, assets where we can bring our incredible capabilities and our extensive experience to bear. Now, we will remain predominantly a U.K. and Irish business for the foreseeable future, but we don't restrict ourselves by geography. We're focusing on areas where we have or can build a durable, competitive advantage that will allow us to create more upside than if we just focus exclusively in one or two countries.
So I would hope that in 5 years, Centrica will be more geographically diverse, but it will be in targeted places where we have deep market experience and insight, primarily from our trading activities in Centrica Energy. That's what supported us investing in batteries in both Belgium and Sweden, and it's how we can deliver future value from future opportunities. We told you in July that we're targeting above GBP 1.6 billion of EBITDA by the end of 2028, underpinned by the transformation program. That's unchanged. Within that, retail and optimization will deliver growth, whilst infrastructure pivots from merchant to regulated exposure. By 2030, we expect retail to reach around GBP 800 million. As Russell explained, we can keep OpEx flat in nominal terms, with top-line growth flowing through to higher margins and higher earnings.
That's after GBP 200 million of additional OpEx that we put in to support the growth that we see. Expanding our capabilities means that optimization can move back towards the top of its existing range, about GBP 400 million of EBITDA, with opportunities to do much, much better in the right conditions. So that's GBP 1.2 billion of EBITDA in total. We expect infrastructure to grow to about GBP 800 million of EBITDA by 2030, and that assumes further nuclear life extensions and almost two-thirds of earnings from regulated and contracted sources from infrastructure by that point. That's up from less than 5% today. Far higher quality earnings... If you bring that all together, we've got good visibility of reaching GBP 1.7 billion of EBITDA by the end of 2028.
As underpinned by the GBP 4 billion investment program we've already told you about, and depending on the opportunity, we may spend even more than that, as long as the value is there. Beyond 2028, we expect to continue investing at the same rate, around GBP 600 million-GBP 800 million a year until the end of the decade, but only if we see the value. By 2030, we're aiming for EBITDA of around GBP 2 billion, with around two-thirds of that EBITDA coming from businesses with regulated and contracted earnings. Now, of course, there's gonna be a range around those numbers to reflect the near performance. There always will be. But that range will tighten as we grow the share of lower volatility, more predictable, more contracted, more regulated earnings.
And given the structurally lower tax rate of the new infrastructure we're building, post-tax earnings will accelerate faster than EBITDA. We're aiming to more than double our EPS in the next five years by 2030. So the picture's clear. We're building a fundamentally stronger, higher quality, more predictable Centrica. A Centrica which continues to morph from a gas company with a shrinking asset base, heavily exposed to merchant prices, into a power company with a growing asset base underpinned by a substantial proportion of contracted and regulated returns. Our operations remain resilient, even in a year marked by external challenges. We've made real progress reshaping this business. More regulated, more contracted earnings, reducing downside risks, creating upside opportunities, delivering against our investment program and recycling capital from non-core assets into higher quality growth opportunities. At the same time, the transformation program is taking hold.
It's supporting earnings today, GBP 100 million of benefit in 2025, and it's laying the foundations for the future. Now, GBP 2 billion of EBITDA by 2030 and more than doubling the EPS is ambitious, but it is very achievable. I am very confident of that. To do that, we'll continue investing. There are fantastic opportunities for us to deliver value by doing that. Super opportunities. Centrica is a far, far stronger company than it was five, six years ago. It's even a far stronger company than it was just a year ago. We've built resilience, we've diversified our earnings, and we've created huge optionality for the decade ahead. We're really looking forward to delivering on that opportunity for our colleagues, for our customers, for our shareholders, to creating real value. So with that, I'm gonna stop talking. We had an aim of making 30 minutes.
I've probably gone slightly over, so I apologize for that. Russell and I will be delighted to take... My God, Ajay got his hand up already. We'll be delighted to take your questions, and I'm sure a lot of them are gonna be number questions or questions on videos that we put on this morning. So, so with that, happy to take all your questions. Now, there's no questions on the phone from online, but if you're online, you can type your question in, I think, and Fraser is gonna have a speaking part later to relay those questions. And we trust, Fraser, that they're not his questions, that they're actually coming from online. So, Ajay, you had your hand up first. We'll go there, and then we'll come to you, Ahmed .
Hi, Ajay Patel from Goldman Sachs. Two questions if I might. Just one on the GBP 0.22 of earnings. So your CapEx beyond 2028 runs at GBP 600 million-GBP 800 million. You look at that and you think towards the end of the plan, you should be around still net cash or broadly break even. What assumptions have you made about buybacks in that GBP 0.22? Or alternatively, is there balance sheet headroom here to further invest or return to investors when the right opportunity arises? And how does, you know, I heard really good comments around risk mitigation. You know, the hedging that you've done on the LNG, the investments you're making to make a higher quality business, but your credit metrics don't change over the last three or four years.
I imagine that should start to bear some fruit, which it should only accelerate the opportunity you have for growth and value creation. And then the last one, I'm being a bit greedy here, so apologies.
We noticed.
Just on the assumptions, what do you assume in the numbers for 2030 for commodity prices? Obviously, quite a lot of volatility. So just to help us understand, what are you sort of holding yourselves? Like, for example, are you making any assumptions around Rough gas storage, Sizewell B, what gas price assumptions, what power price assumptions? Anything you can give us on here just to help us really believe in that achievable GBP 0.22 that you talked about. Thanks.
So, most of those I think are for Russell. Let me touch on briefly that you mentioned about the hedging on LNG, just to explain what we've done there. I don't think the doubling of the share price is dependent upon us having lots more buybacks, so there, there's potentially capacity in there. But on LNG, those of you that have covered the company for quite some time will remember when we had just the Sabine Pass contract, we basically bought U.S. LNG on a Henry Hub index, and the sink market was NBP or TTF in Europe, and the closing cost was $300 million. So if we didn't lift any LNG, we had a $300 million liquefaction fee to pay. Now, if Henry Hub is low and European gas prices are high, happy days.
But if that's not the case, then, it can be slightly more stressful. What the team have done, I think, unbelievably well, and it highlights one of the benefits we've got in Centrica, is over the last couple of years, we've entered into deals with US domestic gas producers, effectively to buy gas off them at a European gas index. So we went to producers and said, "Look, would you like to diversify your range of income, those that don't sell LNG? So you can have some Henry Hub exposure, you can have some TTF exposure." And they said, "Yes." Ultimately, what's happened with a number of deals is we now effectively have taken out the basis differential risk. So we now effectively buy Cheniere on a U.S. Henry Hub index... Sorry, on a European gas price index. So we've matched that.
So the sync sale market and the purchase. So the index risk has been taken out, which is, which is absolutely huge. Massive de-risking of the portfolio. What that's then done is it's given us a position in physical pipeline gas in the U.S. And that's given us the encouragement to open up. We're going to open an office in the U.S. now. So those deals make sense just to de-risk a huge risk out of the portfolio. But what we like to do in Centrica is to look for optionality. So by doing that, we've now got a team in the U.S. that are managing our domestic gas position, and they will deliver value out of that. When we went into power trading in the U.S., we did that. You can do that financially.
We did that from Denmark mainly, but now we've got a team there, and we, we intend to grow that business. And the reason I wanted to kind of pause on that is I'm not sure people realize we've taken that risk out of the Cheniere contract, but it's, it highlights what we like to do in the company. Let's do something that makes perfect sense, but it's got a potential upside. So now with that, there's loads of difficult questions on our assumptions, and if I got that wrong on assuming buybacks, Russell, please tell.
Yeah. So let me just sort of walk you through the spreadsheet a little bit of how we got to those numbers, which might help everybody. So, of course, the GBP 2 billion worth of EBITDA at the end of 2030. So CapEx-wise, we assume we've complete the GBP 4 billion program by the end of 2028, and as a proxy for now, we've just assumed that we have GBP 600-GBP 800 million worth of CapEx in the years thereafter, which will begin to generate a little bit of additional earnings. There's no assumption for additional buybacks in the share count number. That's not because we're not going to do buybacks, it's just to keep your modeling very simple. So, as surplus capital emerges and buybacks become an opportunity, that's definitely something we're looking at.
You remember last year, I took you through a waterfall of how the balance sheet will evolve in the coming years to end of 2028. Nothing really has changed there. So we see that we will invest in the next couple of years, but also begin to build up positive cash flows and rebuild our balance sheet strength, and that gives us optionality, either for more investments or returning surplus capital. So you can use that as a proxy, I think, for modeling still. The other thing that's important, I think, on the modeling is when you look at that headline, EBITDA, and try and work out how that goes down to EPS, you got to remember that the tax rate of Centrica will be going down in the coming years. That has a sort of amplification effect on the EPS.
You know, we've got the second big Spirit divestment this year. Once we've cleared that out, you can see the tax rate will be getting a lot closer to the sort of 25%. Risk mitigation, you asked about, and credit metrics and those types of things. So you said it's been the same for the past couple of years, which is actually not correct. So if you go back to the summer and you read the S&P review of Centrica, we were very happy to see that they have started to give us credit for the investments we've been making in the past couple of years. So the FFO to net debt metric of 50%, which has been there in the past, has now been adjusted to 45%.
But more importantly, if you read the schedules and the outlooks that they're guiding for Centrica, they say, "If you continue to invest in ratable, regulated, contracted assets, we do expect that those metrics will be further loosened." Now, we haven't got that yet, and we've got some adjustments we've got to make through the Grain LNG deal, for example, but we're definitely going in the right direction in terms of credit metrics. And as you look through that period to 2028 and 2030, the proportion of cash flows, as Chris just laid out, going from 45% regulated up to 70% should help the metrics in a good way. Assumptions, we don't do anything too clever. We just look at forward curves in terms of commodity prices, gas prices, power prices.
Gas prices will have a very limited effect on the group by the time you get to the end of this decade, and for Rough in those numbers, we're basically assuming zero, given the uncertainty there. Sizewell will be on a merchant basis, but of course, as we've outlined, there are discussions of potentially getting a CFD for that asset, but that would probably be a longer timeframe than the one that you're looking at. And if we continue with the nuclear reactors, we're just using for the four AGRs forward power prices. So that's how the model works.
Perfect. Brilliant. Thank you. Go to Ahmed, go to Mark, go to Ivan, go to Jenny, and then go to Dominic. So...
Hi, Ahmed from Jefferies. Thank you for taking my questions. Chris, I, I wanted to start with your comments around the pipeline for future investments, when you referenced pausing the buyback. Is that a, is that a topic that we are going to see material clarity over the course of this year? And I, I just wanna... Obviously, we understand sort of the Rough discussion that you referenced earlier, but what else is in that pipeline? So interested to sort of, sort of get more on it. I also wanted to ask you about sort of the nuclear life extension. So you sort of referenced Sizewell B, but is there a opportunity or to get meaningful nuclear life extensions on the rest of the fleet as well?
And is that sort of reflected in the doubling of the EPS by 2030, or is that sort of just based on as you sort of see things today? Then maybe a question for Russell. Russell, I'm trying to just sort of understand a little bit better your guidance for 2026 and where that may differ from consensus. So if I add the various divisional data points that you have given us on EBITDA and then adjust for consolidation for sort of last year, it's, it feels like almost GBP 1.4 billion group EBITDA, which is not very dissimilar from where consensus is. So is that sort of a fair interpretation? So, and then it just seems to me sort of the big difference really where is where consensus expectations is on the interest cost.
Again, you know, please tell me if you disagree, and I'm just trying to understand why is the interest cost that variation, if you can give us some color on that. Thank you.
Brilliant. Okay, there's quite a lot in there. So, I would hope we get material clarity, through this year. So the government's gas consultation closed yesterday. We made a submission under that. I thought that was... I was really pleased to see it. I wish it had come out a bit earlier, but, you know, very pleased to see how it was written. And it certainly recognized the importance of gas storage, as did, NESO's recent report.... and as the U.K.'s largest gas storage facility, I think Rough is very well placed. So I feel more confident about Rough, but I'm also very clear-eyed about it. So either we get something that makes sense for us to unlock the GBP 2 billion, create over just under 5,000 jobs in the construction phase, or, or we don't.
This is why we keep a huge pipeline of opportunities so that and there have been things that we've had in the pipeline that we've walked away from days before signing, and we can do that because we know we've got other stuff there. So Rough would be one I would hope. We have been discussing more about X-energy. So the government's recent publication of how they'll support small and advanced modular reactors is asking for submissions by the... Oh, sorry, starting on the fourth of March. Clay Sell, the Chief Exec of X-energy, and I were in seeing government last week talking about this. We expect to submit something, hopefully on the fourth, but, you know, sometime around then.
What that will do is lay out what we would be, we'd be looking for to advance probably what is maybe a GBP 10 billion investment or so, GBP 9 billion or GBP 10 billion for Hartlepool, for 1 gigawatt in Hartlepool. But what it will lay out is we actually see this as being a GBP 50 billion or GBP 60 billion program, so about 5 or 6 gigawatts of these reactors across sites in the U.K. And you know, again, a lot of these things are kind of binary because you either get the support framework that you're looking for or you don't. But the government are super keen on nuclear. There's cross-party consensus on that between the two main parties, because Sizewell C was started by the previous government and finished by this one. So it's an area where they all seem to agree.
We think X-energy is some of the best technology out there. We're still looking at Rolls-Royce SMR technology as well, and we see a huge opportunity. So that's something that we could see. Now, I don't think you... You're not gonna see massive CapEx on that in 2026, because you've probably got several hundred million GBP of pre-FID expenditure on that to make sure that the sites are right, but I hope we'd get some acceleration there. Morecambe Net Zero is progressing quite well also. So we see, we saw the National Wealth Fund coming in to take a proportion of the cost in the feasibility study for the pipeline from the Peak District cement producers over to the West Coast.
We get mixed up, it's the East Irish Sea, but the West Coast of the U.K., and it specifically recognized the role of Morecambe. So those are opportunities that we see quite substantial upside, and hopefully we get some clarity. We expect to take final investment decision on the gas peaker in Galway, in Ireland. That's probably, what? 340 MW, so that's probably EUR 400 million-EUR 500 million, I think. You know, we're looking at a slightly lower number, but I think you're looking at over GBP 1 million a megawatt, I think for construction. So that's probably... I would estimate, I don't know if Dave's listening. If he is, I still expect a low price, but I would estimate about EUR 500 million on that. I'd hope to take investment decision this year.
Again, if we get to the point where we say the numbers don't add up, we won't do it. So, so there's quite a lot in there. There's also some stuff we're looking at. We have been very open that we're looking both at organic and inorganic options. The inorganic options are more likely to have more of a skew towards contracted and some merchant exposure, a bit like Isle of Grain. And the reason for that is we don't have the cost of capital to compete with others to buy existing regulated asset-based businesses. That's why we're creating them, that's why we helped to create Sizewell C. We want to create that in Rough, we want to create that in Morecambe, because we just-
It wouldn't make sense for us to compete against people with a cost of capital 200 or 300 basis points below others. So we hope we'd, we'd get some there. On the nuclear extensions, to be super clear, the, the GBP 1.7 billion of EBITDA was GBP 1.6 billion. The difference between those two numbers is we expect extensions. So two of the plants, two of the advanced gas-cooled reactors are due to go out in the end of March, I think 2028. We expect those to be extended. If they're not extended, the guidance is GBP 1.6 billion, so there's just under GBP 100 million in there. The other two are due to go out of service, I think, in March 2030.
There's probably 10% of the GBP 2 billion EBITDA, which relates to having the four advanced gas-cooled reactors working all through 2030. So it's not purely dependent upon that. The numbers are in there. Now, I don't think these things will be going by 2040. I don't even think they'll be going by 2035. I think we will... We have to watch the degradation in piping, in the boiler work, and in the graphite core, and I think we will get a series of one or two-year extensions. But at some point, it will be a case where we'll have to shut these things down, 'cause they're nuclear, they have to be safe. So I'm increasingly confident we can get them going to 2030.
Hartlepool has been out for quite a while, which is frustrating, but effectively that's less wear and tear, so you add that on to the end. So I think we'll get those extensions. I think I said before, if we were offered the chance to sign up just now to these things running until and shutting down in 2035, I'd sign on the dotted line, 'cause I don't think they've got much life beyond that. Russell, 2026 guidance.
Let me talk everybody through that. It was on the slide, but let me just go into a little bit more details. Retail, previously, we had guidance ranges for the individual businesses. We've simplified that and tidied that up, so a range of GBP 500-GBP 800 million for all those businesses. You can choose your midpoint maybe as a way to get started there, but I think as we sit today, we're quite comfortable with how retail's looking for the year. Optimization, I was clear about that in the speech, below the GBP 300-GBP 400 million range, so GBP 250 million, as we said today, for that business. Infrastructure, again, a little bit dependent on prices, although we've hedged a lot of the nuclear production and the Spirit production this year. We've guided GBP 500-GBP 650 million.
Some of that's also dependent on when the Spirit Energy second divestment closes. We're thinking around mid-year, so perhaps you could take the midpoint of both of those. You mentioned you'll use the consensus adjustment that we had this year. I think that's a good proxy, so I'd pencil that in. That's fine. And then there was the interest expense, where we noticed that some people modeling Centrica just hadn't quite got that correct, so we wanted to just flesh that out today. So GBP 100 million cost for 2026 is our current expectation. Let me just give you the math behind that, because it's quite important. So Centrica, of course, has some debt from quite a few years ago at relatively high interest rates, and a large cash balance, which is all floating.
What's happening is, as interest rates are going down and half of your debt stack is fixed, your, the amplification on the reduction in your interest, is, is more pronounced. So just for example, the rate that we paid on the bonds in 2024 was just over 7%, reduced to 6.6% in 2025. But on the cash, a steeper drop, because it's all floating from 5.1 to 4.36. So you've got both higher fixed-rate debt, and it's not all floating. So that's part of the dynamic. The other thing you have to take into account is there's a difference between P&L interest charge and cash paid on interest. That's things like decommissioning and other things that move through the P&L, but not through the cash flow statement.
Let's call that around GBP 40 million-GBP 50 million, which you'd probably want to adjust as well. So, the IR team will be very happy to, to walk you through the intricacies of our debt stack, but I think that's probably the best explanation I can give you from here.
Good. Thanks. Mark, and then Pavan, Jenny, and then Don.
Mark Freshney from UBS. Hi, Mark Freshney from UBS. I have three questions. Firstly, on the LNG hedge position, which I, I think is 100% out until 2028, is that, to use your parlance, written in black ink or red ink? Just secondly, regarding the Rough storage facility, which you now expect to break even, is that all because you're extracting the cushion gas? And I guess the third question is more philosophical about the efficiency plans. I mean, businesses continually need to do efficiency plans, and the ones done by your predecessor and your predecessor before that, the benefits seem to go back to customers.
And when I look at, Chris, when you mentioned your transformation plan, I think it was six months ago, and you said there would be upside to the GBP 1.6 billion or the, the range, GBP 1.3 billion-GBP 1.9 billion. Here today, we find that the only upside is the GBP 100 million from nuclear life extensions. So should we be conceptualizing the efficiency plan as business as usual and something that protects existing efficiencies or the existing businesses and profitability? Or will this be the one plan, apart from the one you did a few years ago that did show through, but is this going to be one that does actually bring shareholders any benefit?
Let me do the last one first. I hope so. So the, with a GBP 100 million benefit in 2025, but we booked the costs in core earnings. So most companies... And what we used to do, when I joined, I was talking to the chairman this morning, I think we're the only two left on the board from that point. When I joined, we had this massive cost efficiency program, and we were spending hundreds of millions GBP a year in the middle column, and everybody said, "Well, it's in the middle column. It's great." You know, it's bloody well cash out the door. And, and, and actually, I would argue, rather than that going back to customers, our costs didn't actually go down, they went up.
And so we had lots of—it's not smoke and mirrors, but we had lots of ways of explaining why we've done a really great job of taking out cost, but we put costs back in. So with the first presentation I did as CEO was to show that we'd taken out 15,000 people, and the wage bill had gone up. So I don't care how many people work for us, I care what we pay. And so I actually don't think that delivered much in the way of benefit. And I had to present every six months the some somewhat convoluted story about cost benefits and OpEx. But I just, I, I think we were, I think we were kidding ourselves on. Now, look and say, I don't know, 65, our OpEx is GBP 65 million lower in 2025 or thereabout than it was in 2024.
Now, the reason that you'll see some going back, if you take, for example, X-energy, I'm probably going to get a kick for saying this number, but, but we would anticipate for that project, the first project for 1 gigawatt of advanced modular reactors, the pre-FID spend will probably be about GBP 600 million. You can't capitalize that. That's expensed. Now, we wouldn't expect to pick up all GBP 600 million, but that's why when Russell said, we expect to keep costs flat over 5 years, offsetting inflation, but also offsetting the fact that we expect to have a couple of hundred million of growth-related expense. Some of that will be as we go in more to building some things ourselves.
You've got your, you've got your pre-FID spend, you've got your front-end engineering and design, civil engineering works, all of that kind of stuff. I think you should be able to capitalize that on a successful project investment decision. I don't set the accounting standards. So, so you'll see some of that in there. We would expect to spend more. But again, only if the value is gonna be there, but we're gonna have to be slightly more speculative, I think, in some of that. So I think the efficiency program will deliver. Rough storage is absolutely because we're taking out the gas. We're not injecting. However, we reserve the right. You know, Cassim's team work very closely with Martin Scargill's team. If today, for example, we see the chance to inject at GBP 0.10 and sell at GBP 0.50, we can inject.
We can change the flow in Rough three times a day. The nominations, you make three different nominations, I think. But our modeling is simply that we're gonna take the indigenous gas out, and at some point, the pressure drops to such an extent that you can't get any more out. And then on the LNG hedge, I would just say nice try. That would be commercially sensitive. I would say that we expect to, I think to be moderately flat, but it's not so much we've hedged everything in, and it's all flat. There's still work that the traders, the traders are very, very busy, in Cassim's team. But I don't know, Russell, if you want to give any more from on that LNG.
Just to remind everybody that the LNG business is much broader than just the Sabine Pass, the Sabine Pass contract into the U.K., which is where it all started. So 25 cargos a year from Sabine Pass hedged, 250 cargos traded last year. So the LNG business is much broader than that one contract, and our traders have demonstrated over the past couple of years how they're able to get into positions in a really creative way to create value. So I'd take that into consideration as well.
Excellent. Pavan, good to you.
Thank you, team, for your presentations. Pavan Mahbubani from JP Morgan. I'll ask you two questions, please. Firstly, Chris, I want to follow up on Mark's question on the transformation program and the retention of those benefits. So if we exclude the pre-FID expenditure and everything else, how are you comfortable that you can retain any proportion or a good proportion of that relative to your competition. I guess the question I'm asking is, what's different about Centrica versus what some of your peers will be doing in the businesses where you're driving these efficiencies? And then the second question I have is, can you unpack a bit more the drivers of the lower optimization trading profits this year?
My question is, how do you expect those factors to evolve, i.e., when we're thinking about 2027, 2028, should we assume you're back to the midpoint, or is it a gradual ramp-up based on market conditions as you see them today? Thank you.
Okay, let me take the first one, then maybe Russell can take the second one. So you're talking about in the retail business, effectively. So if you look, most of our competitors are losing money in the retail business, and Russell mentioned about unsustainable pricing that we're seeing. We're just not going to play that game. I've always been dubious, if I'm being very open, of a value over volume explanation when it happens after the fact. And Gary, who runs B2C retail, and Dan, who run B2B, were quite clear when we spoke at the start of the year, saying, "If we think that it's value over volume, we say at the start of the year," so it's not an explanation for losing customers.
I think if we end the year with flat customer numbers, I'll be delighted. I think customer numbers probably will be a bit down because we're not going to chase unsustainable pricing. But in the regulated price cap part of the business, what you really want to do, and it sounds very uninspiring, is to be better than average. So if we run better cost-saving programs than our competitors, we put them under more pressure. If they're making losses, they're under even more pressure, and you cannot resist gravity in perpetuity. So if we look at our biggest competitor, Octopus, I think their last account showed that they doubled their OpEx, and they doubled their headcount.
We've always thought that when you get to a point where you have a broad range of customers in the B2C retail book, your costs are going to go up because some customers are dead easy to serve, and some customers are slightly more difficult to serve. We have always had a very broad range of customers. We value every one of them. We have efficiencies. We know how to deal with all the range of customers. We have efficiencies that we can put in place. Some of these companies are learning how to deal with customers with more complex needs, and you see that their costs are growing. Our cost to serve is lower than Octopus's cost to serve today. We already have a cost advantage. The cost advantage that is portrayed through a different system, the numbers don't...
You can see this in the consolidated segmental statement. The numbers don't bear it out. So we have a cost advantage today. Now, is it possible that we put through lots of cost savings and the regulator absorbs that into the price gap? It's entirely possible, but by doing so, they'd put other people out of business. And if they do that, then it's an uninvestable market. They want an investable market. We pick up other customers, but at some point, this market has to have enough profit in order to attract the investment that's required. We're not perfect, and we've got loads of opportunity. It's funny, every year we make... Like, our customer service, our customer satisfaction numbers, they're as high as they've ever been. But the opportunities I see today are more than I saw five or six years ago, when it was pretty low.
So, like, every time you improve, you just see more opportunities, and I think that's what great companies do. You just continue to improve. So if you're behind somebody, you catch them up more quickly. If you're ahead of them, you just increase the gap. And so we're going to continue to invest, and we're going to continue to invest in customer service. We're going to continue to invest in delivering efficiencies. And I'm as confident as I can be that not only will we deliver the benefits and retain some of that, but that we will deliver the GBP 1.7 billion and the GBP 2 billion of EBITDA in 2028 and 2030. It's going to be difficult. It's going to be hard work, but it's entirely possible.
So, so I think we'll be able to retain some of that, but if we don't, and the regulator takes it all, that's still, for us, competitively, is not a bad position. Might mean we make a little bit less, but the market has got to be normal. And the 2.4% margin today that we've got, which is causing a lot of financial distress. You know, there's five companies now, I believe, that don't meet Ofgem's own financial resilience rules, so it's getting worse. That means they're eating into capital that they've got in order to stay in the business. That's not sustainable. What we could have done was, and I've always had this view, we could have sat for four or five years and said, "You know what? The market's going to come back to us," but we haven't.
We have invested heavily in improving our customer service over the last four or five years, but I still believe the market's going to come back to us, but we're going to continue to invest constantly. We're not going to sit and wait. Kasim often talks about complacency being a word that worries him, but we're not complacent at all. So we'll keep pushing. We're going to deliver these efficiencies. Maybe we're going to deliver more. If the regulator takes them, that's fine for us. We're always looking for something whereby whether you go left or right, you win. And whether the regulator allows us to keep them or whether the regulator takes them back, in the long term, that's not bad for us in this market.
I do think we ought to keep, but the proof is going to be in where the OpEx is. I think that we've-- we thought long and hard about this. I didn't like when I was CFO, putting restructuring costs through exceptional items because the organization thinks it's free money. So whilst it's slightly painful, and we would otherwise be talking about 13 pence EPS, and we'd be talking about, you know, we're going to invest even more in 2026 in transformation. But we want to make sure that we-- everyone understands that when you spend a pound on transformation, you have to get more than a pound benefit. Otherwise, let's not spend the pound. We'll separately identify that, I think, each time we do the results, but they'll be in the core, the core results.
Lower optimization. When's it going to change, Russell? When is the market going to change? What date?
Well, you speak to Kasim. He's just sitting there. You can,
All right, now actually, so there was disappointment in the second half of the year, and where we thought we might have ended up in Centrica Energy versus what I told you at the mid-year. I mean, if you sort of stand back, I mean, commodity markets, as we know, are inherently volatile, and we saw that through the energy crisis and a sort of different type of volatility and movements in the past couple of years. And so you had that exceptional dislocations in 2022, 2023, and then you moved into a period of elevated geopolitical concerns, risk, high volatility, but hard-to-read volatility. And then at the end of 2025, we did see the beginning of a broad-based normalization across the global gas hubs, but it didn't really go back to where it was before.
And so that meant that in the second half of the year, our gas and power trading business continued to face challenging conditions, and we didn't see the improvement perhaps we thought we might have. Just to remind you of the sort of core of that business, when we see seasonal and locational spreads, our core strategy is, our fundamental base strategies are to take gas storage positions, power positions, interconnects, and all the rest, and then through analysis of supply and demand, put positions on. And although there was an improvement in the second half of the year, there were a couple of factors that made it more challenging. The level of the summer-winter spreads was still too risky. The margins were not quite there, so we didn't put that much risk capital to work.
And also, the movement back into more normal market conditions happened really quite deep into the injection season. So Centrica had not taken as much capacity and therefore has less optionality as moved through the current period. So that just meant we've got a bit of a, you know, we're starting in the back foot a little bit for 2026, hence the main reason for moving the guidance down for this year. And you've seen in recent days, there continues to be regulatory news flow changes in the market that just make it more difficult for us to step in at the moment. But does that mean that we feel that there's a change to our longer-term outlook for that business? Absolutely not. We've got a great team. We trade across 28 countries in Europe.
The gas and power markets, when they do stabilize, we'll have, we will be there with the risk capital, ready to get back to work. Our renewable route to market business continues to grow, now at 19 gigawatts under management. That's got a stable cash flow base to some extent, and the contracts we write and optionality around that. LNG, we've just discussed a lot of optionality there. We're growing our business in gas and power trading into the U.S. We now have an office there. We're beginning to trade both physically as well as on the exchange. That helps us underpin our natural gas supply into Sabine, but it also gives us more optionality as well.
If you take all of that together and a broad assumption that markets will normalize, we're comfortable we'll get that business back into the GBP 300 million-GBP 400 million worth of EBITDA that we've seen before.
Thank you. Jenny, let's go for you.
Thanks very much. Jenny Ping from Citi. A couple of interrelated questions, please. Just firstly, I was very intrigued to see your slide on CCGT, and obviously, you guys have been linked to potential merchant capacity, and interested in your comments around the cost of capital. So when we look into the 2030 numbers in terms of that predictable earning stream that you talked to, how do you plan to deal with this merchant capacity if you were to go down that route, especially in the context of some of the changes in the commodity markets we've seen recently, the Italian decree, the merit order comments from the European Commission, and a more headroom coming through in the capacity auctions? So would be interested in that as a first.
Then secondly, just on, I guess, affordability and bad debt. Obviously, bad debt continues to go up. You commented that the expectation is to see that to be recovered. What I can see is, you know, the government's only talking about 10% of the overall GBP 5 billion as a first tranche. What gives you that confidence to see some of your bad debt on your balance sheet to be recovered, and that continues to go up? Thanks.
So look, on the CCGTs. So we've always been clear that we look at regulated and contracted, and so how I think the market's going to evolve, and the government will say this, Chris Stark, who's, like, he's got a great job title, like he's head of mission control or something for clean power. And Chris will tell you this, that he expects we'll have to rebuild the entire U.K. CCGT fleet, but we're going to have far more renewables. And so ultimately, CCGTs, which might provide baseload just now, will provide backup generation going forward. So CCGTs will just be like peakers.
And so what you're going to have to have, the way the market has to evolve in order for this to happen, is you have to get capacity market payments, which is attractive enough for you to keep the asset open. And it will have to cover basic maintenance, et cetera, and a return on capital. And then you'll get the positive spark spread when you have to run. And if you have to run and the spark spread's negative, you won't run. And because you need electricity at the point you need to run, the spark spread has to be positive. So it's like if you take it from a macro level, if the rent doesn't exist for CCGTs, CCGTs won't be there. So when we look and say, I don't think the... You might get to, like, RAB models.
I'm not—I don't think so, but I think it'll be more the capacity markets kind of try and test if people seem quite comfortable. And I've been quite open. Like, I would love if we had a bigger position in thermal power generation because I think that what will happen is that you'll see this morph into more capacity market contracts, but as we're finding in the Irish because things always go wrong when you do a project. Always. There are very few projects. I think Heathrow Terminal 5 is the last big project I saw that actually went incredibly well. Everything goes wrong, it's late, it costs too much money. And so the build-out renewables, which is very, very ambitious, will not happen in the timeframe that we think. It will happen, but not necessarily bang on budget, bang on schedule.
So the gas-fired generation you've got will have to run. So you'll have the capacity market payments, and you'll have the positive spark spread, and it's, it's really quite typical of the, the asset classes that we're looking for in Centrica, which is something that makes sense in the base case, and you make a decent return and has a skew to the upside. Because the downside of these assets will be if your maintenance isn't good and you get called on, you're gonna be in a whole world of pain. We know how to run CCGTs. We're pretty good at it. We've got a big one in in Whitegate, in Ireland, and so we know how to do that. So the downside is in your own hands, and the upside is probably gonna come from the market.
Those are exactly the kind of assets that we, we'd look for, but they're not regulated, but they are heavily contracted. If you look at Isle of Grain, it's mainly contracted rather than regulated. Now, why did we feel that we had a unique bidding position in that? Well, we know that asset 'cause we've got a quarter of the capacity, but our capacity is up in 2029, and so we know today, so Kasim's team figured out what we would bid in 2029 for that capacity. And so when you look at it on a standalone basis, that sets a floor because we will either bid and get that capacity, and we know the return on the asset, or we'll bid, and we won't get the capacity, and the only reason we wouldn't is 'cause somebody's bid more.
So we're always looking to say, "How do we establish the floor?" And although I've got quite a high risk tolerance, I am always looking at the floor, how solid is the floor and then what can you build on top of that? So CCGTs, I would love to be there. The trick is to be in the right place in the merit order. You then touch on what happened in Italy about the carbon pricing. Unless you had a rock-solid... So it's quite clear there's gonna be some movement in terms of whether how, where carbon pricing is gonna go. So unless you have something that's rock solid, irrevocable in terms of spending money and lots of carbon capture, you're probably not doing that at the moment, and what the news from Italy the other day probably undermines that.
But we're not looking at that just now. So if we were to look at a power station with CC, with CCUS, carbon capture, utilization and storage, we'd have to make sure that, that that was irrevocable, that that was absolutely cast iron. You know, Russell would be looking at Raj or General Counsel would be looking at that, and if it wasn't, we probably wouldn't do that 'cause that is too much of a risk. And some people will have woken up on Tuesday morning to the news from Italy, thinking, "O ur business model's under threat." We will never be in that position. We're always looking to see, how do we spread the risk? How do we guard the downside? How do we make sure the contracts are with the right counterparts?
How do we make sure that the regulation is absolutely cast iron? So now, you could look and then say, "Well, what if a future government changed the law?" Well, if governments change the law and undermine contract rights, then countries become uninvestable. That's what you see in some developing countries. I don't think the U.K. will get to that point because if it did, the capital outflow would be absolutely huge. So some of the stuff we look at at a very detailed, micro level, how tight is our contract? And some of the stuff is a very high level, macro level, which is, okay, if the worst happens, what does that mean for the country?
Because we are kinda tied into, we need things that are good for the country, we take a view as to whether something's likely or not, but it's also why we look, for example, at spreading our geographic risk. I think we've, you know, fixed our operations. We've started to invest, but we look and say, "Well, there's more that we can do." The office in the U.S. is one thing. I would expect us to enter 1 or 2 new countries outside Europe in the trading business this year, and, we're in very small positions in Belgium and in Sweden, but I'd be quite happy to grow. And then I don't think in 5 years we're gonna be in 20 countries, but I don't think that we're gonna physically be in 2 or 3 or 4 countries.
I think you're gonna have something that's less than 10, but more than 5, and that also helps you with the risk. Yeah. Bad debts, you want me to? I mean, I'm happy to have a go and get it wrong, and then-
Oh, I'll appreciate that.
Look, I think at the high level, in the bad debts, bad debts are recovered through the price cap. That's why I think people don't appreciate how regulated the earnings are in British Gas, residential energy. So you recover it through the price cap. If you're better than average, it's a profit center, and if you're worse than average, it's a cost center. And debts are... I think they've gone up fourfold or something, so the debt on our balance sheet is GBP 1.2 billion or so. It's absolutely huge. The thing I worry about more is that means that there's a bunch of people that can't pay, so something's got to happen in order to fix that, but the regulator has got to come up with the right answer. We call for a social tariff.
We've been calling for that for quite some time. We can't differentiate between those who choose not to pay and those who really can't pay. We wish we could. And if we get a social tariff, then those who can't pay will be treated with compassion. And at the extreme, a social tariff would mean some people will get energy for free. Those of us that can afford to pay more will see prices go up, and that's right. And those that can't afford it at all could ultimately see free energy. And those who choose not to pay, well, then you'll be able to take action against them and...
Because at the moment, because of the way that the price cap works and the cost being socialized, those who simply choose not to pay are being subsidized by those who do pay, and that's wrong. Because there's a lot of very poor people that are paying their energy bills, they shouldn't be subsidizing people that can afford to pay. So, it's high. It's a concern. It's a working capital issue. This is why we campaign for financial resilience, 'cause we've got the working capital. We've got a very good CFO who manages the balance sheet to make sure that when, you know, Gary's business needs a flow of GBP 100 million, GBP 200 million, GBP 300 million, GBP 400 million, GBP 500 million working capital, we have the cash, we have the liquidity.
We campaign for financial resilience 'cause those companies that run it very, very tight in the balance sheet. I don't know how they're coping with this at the moment. We don't think that systemic risk should be left with consumers, which it is just now, 'cause if they go under, consumers ultimately pay the cost. Did I get my numbers right or wrong?
Nearly.
Okay, okay.
So actually,
Broadly correct.
If, broadly correct. So it's actually GBP 1.9 billion worth of net debt on the balance sheet, including both build and unbuild. So that's a, that's a challenge. And if you look at note 16 in the accounts we published this morning, what you'll see is that's predominantly in that greater than 360-day category. So that's the same trend that British Gas is seeing as the rest of the industry is seeing. Our bad debt charge as a percentage of revenue went from 2.3% to 2.8% in the year. So about GBP 40 million increased charge. So it's a weigh on the P&L, but as Chris says, over time, we're expecting to get a recovery for that.
But it's that older debt that's the real challenge.
Okay. Very good. Excellent. Dominic, I'm gonna go to you.
Hi there. Yeah, it's Dominic Nash from Barclays. A couple of questions from me, please. The first one, I think it's to you, Russell. I think you mentioned before that you previously published a waterfall chart, and on the waterfall chart, you know, you came up with your EBITDAs, your CapExes, your requirements, and then you also said that you had a net debt EBITDA sort of target or goal of between 0 and 1 times, I think it was, for one sort like a, a limit and one sort of like a target, I think. But on our numbers, I think that gets to about GBP 1 billion of sort of headroom, which I think quite a few of us in this room probably earmarked as buyback, rather than anything else.
Can I just confirm that that sort of headroom still remains, and it's basically just now either gonna be option on CapEx and less likely to be buyback, but whether the headroom is still about GBP 1 billion? And the second question is to you, Chris. Actually, it's kinda half following up from Jenny's one on gas. Sort of double one here is that the government clearly has a policy to decarbonize completely, and you are bringing up the doubling of CCGT output. And so one of my first question is why are you doing that when you can't build this side of 2031 and you don't have any CCGTs? So what sort of message are you trying to tell us about that?
And secondly, clearly, under the current government, I think there is no doubling of gas expected, and in fact, gas has continued to go down. So do you have like a roadmap to whether or not we could see the gas strategy change this side of 2029? Or do we think we're gonna need a sort of change in government before we end up with a more sort of gas as a transition fuel, sort of narrative? Thank you.
So look at...
Good question. Let me take the one on gas. So the numbers that we showed were from Aurora. So they're external numbers. That's not our internal forecast, that's an Aurora forecast. And the double in the CCGT is in the mix rather than our position. I think it, you know, I think it depends on what you think is gonna be the builder, but the more intermittent electricity we've got, the more gas-fired generation we're gonna need. And then the question comes in terms of: how much economic growth do you think there's gonna be? How much increase in electricity demand do you think there's gonna be? Now, there's a huge notional increase in demand from data centers. I think when you look at the physical requirements of building... Everyone talks about a gigawatt data center.
I think that's half a square mile. Apparently, it's $5 billion worth of chips in the plant. We would build a power station for $1.5 billion or so, and you might build it co-located, not connected to the network. It takes you 5 years to get a turbine, so as you say, out to 2030. How do you do all of this kind of stuff? The numbers we're seeing are out in the, I think in the 20, by 2040. So there's a whole bunch of stuff in there that Aurora might have got right or might have got wrong. My belief is that, we will see growth in electricity demand, we will see economic growth in the U.K., and we will see growth in CCGT as a share.
Now, we've got a big biomass plant on the U.K. Will biomass survive or not? 'Cause we've been talking about biomass BECCS with carbon capture and storage. So, so you might see a change in that mix, so gas might replace, 'cause there are lower emissions from gas than there is from biomass. Whether you buy the argument that, that it's renewable and biomass is, is a political question I don't want to get into, but you could see a change there. That's about 3 gigs or something that's on the system just now. It's about 8% of U.K. demand. Obviously, you'll see the reduction in the... By 2040, the four advanced gas-cooled reactors will be off. That's 4.8 gigs. Hinkley C should be on. Sizewell C definitely won't be on by, by that point. Oh, sorry, definitely.
I'd be amazed if it was on by that point. I'd be delighted, but I would be amazed. I think roughly around there. So there's a whole bunch of assumptions. What we know is the assumptions will be wrong, but you will need more gas-fired generation. The question about how much electricity will be generated, I think that's open to debate because we don't know what the weather patterns are gonna be like in 2040. But we can take the risk that intermittency increases because weather patterns become more changeable. So you're gonna have to have the capacity, which is why you're gonna have to have the capacity market payments, which is why they're an asset class that we like. Whether they will generate 300 days a year or 3 days a year, I have no idea. But I like the kind...
If it goes for 3 days a year, we're happy it meets the cost of capital, exceeds the cost of capital, and it goes to 300, then we're making a lot more money and bringing down costs for customers. So, there's a long time between now and 2040, but I think the current government recognizes gas as a transition fuel. I think the question on some gas ex- I was in Qatar in November, and one of the senior Qatari energy ministry people said that they don't think gas is a transition fuel, they think it's a destination fuel, and they said, "Can you deliver that message in the U.K.?" I said, "I'd rather not get involved in that stuff. That's for you guys to deliver.
But I think what that signified is they no longer see, like, blind decarbonization as being an issue, and therefore, they've probably got more discipline in terms of how they're going to get their gas out of the ground. And I think we're seeing a lot of pragmatism in the U.K. as well. I think if you look at that gas consultation, that's not the consultation of somebody who's pursuing blind decarbonization. It was a very measured, very sensible consultation. NESO, who come out and recognize the need for gas storage, is a government body now. And so I think we're seeing a lot more pragmatism. And what we try and do is to just steer away from all of the kind of politics and all the headlines and stuff about, you know, net zero this.
The reality is, what we're trying to do is to decarbonize, have secure energy, and have it that's affordable, and we think CCGTs are going to be right in there. I would love to have more CCGTs, but only at the right price. If you know, if somebody else has a lower cost of capital and they'll pay more, then fine. I think at the moment, people are struggling to value these asset classes. I don't think they're attracting... Like, if you've got a really low cost of capital, you want to buy a network, or you want to buy, you want to be in the CFDs or wind or something, then that's where the lower cost of capital is going. If that allows us a chance to get in and build a CCGT position, I would be delighted.
Great. And then just moving on to the waterfall chart from last year and the financial framework for the coming years to come. So no change to the expectations or the overall framework. And just to remind everybody, because we don't have it on the screen today, what we were looking at there was the evolution of the balance sheet, where on one hand, you had the completion of the GBP 4 billion investment program, you had the continued progressive dividend, you had the, you know, the other liabilities, pensions, decommissioning, but you also had alongside that, the cash generation from our existing assets and our new assets.
We sort of pushed that all forward to the end of 2028, and what we could show by then is that we would be able to move the balance sheet up to approximately a 1x net debt to EBITDA level. We would have a bit of a buffer and reserve just because of the volatility of the business. Over time, we would expect that some additional financial flexibility could come to bear. And that's right, that was about GBP 1 billion. I think roughly ups and downs, that's probably the same proxy that I would look at today. But it's not there today because, of course, what we've got to do at the moment is move through the next couple of years, continue to generate from our existing assets.
We've only spent 2 of the GBP 4 billion of the capital program, so that needs to come out of the balance sheet into new assets. And we've paused the buyback because we think there's more value at the moment for us to continue that investment program, and then make sure we've got a really strong set of cash flows in the future, which gives us much more optionality in the in whether it's buybacks or other sources or use of capital.
If I could, we go to Harry and then back to Ajay. I'm conscious of people's time. They'll come Fraser, I don't know if there's any questions online. One thing I would say is that there's like, I always when I was a CFO, I always used to run a slight, what people call a slightly flabby or conservative balance sheet. But seeing like there's always a point in the cycle where you think, "Thank God, we've got a balance sheet like that." Either because you go into a bit of a downturn, and you need to float working capital, or because your competitors are highly leveraged, and you get the chance to pick assets up at a low price. So there is a benefit in us having a slightly more conservative approach to our balance sheet.
But hopefully, people see the fact that we've bought back over a quarter of the company over the last three and a bit years. They see that we're super committed. I mean, we know who we work for. We work for the shareholders. We get excess capital, we give it back. But we think it's in shareholders' interest for us to have the optionality to act and to pick up assets or to not worry because you find out, for example, that Ofgem's next quarter's bad debt recovery charge is not as high as you would like. There are some of our competitors who I think it's an existential issue for them as to what the next price cap, but it's not existential for us at all, in the short term.
But Harry and Ajay., and then we'll go to Fraser, and I'm just conscious of everybody's time. I know we're kinda, we're dragging on a bit. I'm sorry.
Yeah, thanks, Chris. I'll make it quick. I appreciate we've gone through a lot of stuff already. It's Harry Wyburd from BNP Paribas. And so two, I'm surprised it hasn't been asked yet. The buyback, what's your threshold for reintroducing it? I guess, like, you, in, in the past, you've been willing to be quite flexible. You know, last time that your shares fell a little bit after pausing buybacks, you resumed them in quick order. Is there a share price threshold, below which you'd be interested in, in restarting buybacks? Is there, you know, an opportunity cost threshold? What, what, what would cause you to resume the buybacks? I guess another observation is that your, opportunity cost on cash, right? Because your cash treasury rates have gone down.
It's, you know, you have less to lose in terms of interest income if you spend it on buybacks instead. So that's the first one. And then the other one's on the capacity payments. I wholeheartedly agree with you on capacity payments. I think this is something that everyone's, not everyone, but a lot of people are missing right now. I think gas is gonna become a regulated asset in Europe, and there are still countries which don't have capacity markets, which are gonna need them. Would you look in Europe for orphaned gas plants? Look at the Netherlands, for instance, where there's no capacity payment, there's no spark spread, but those plants could become very profitable if you did get a capacity payment.
You've expanded internationally with your trading business, so why not become an aggregator for orphaned CCGTs in Europe and then clean up when capacity payments massively rise at the end of the decade? Loaded question, but-
Wow.
Yeah.
It is. You're not selling CCGTs in the Netherlands, are you, by any chance, no?
Sadly, not.
Look, I think that, I mean, Russell and I both used to work for the same Dutch company or a company that was Dutch at the time. I think Russell spent quite a number of years living there. I like the Netherlands as a place to do business. However, there was quite a big court case in the Netherlands about decarbonization targets. So, you know, maybe there's some orphaned assets there for a reason, but the Netherlands would be exactly the kind of market that we would quite like. It's, you know, good rule of law, et cetera. And if there's value there, and we know the market, and Kasim's team know the market well, then why not? But we are-- We don't look and say that's the kind of place we want to go. We want to create value.
If you take, for example, a market, we say, well, there's no capacity market at the moment. There's no spark spread there. That's a bit more of a punt, I think, than saying, "Okay, we can see a market where there is a capacity market already. There is a good liquid market." We can see the assets, there's less of a punt in that. And our whole thing in whatever it is, whether it's technology, whether it's in buying assets, is not to take the risk of being the first mover, but being able to move when somebody establishes that something's possible, being able to move quicker than the competition, and sometimes even being able to move quicker than the first mover in taking advantage of that.
So, don't hold your breath for us to be coming back and talking Dutch when we're there. But I'd love to build a position there. The buyback threshold, you know, fine we're not gonna give you an answer. I think our share price today is undervalued, not because it's down. I think it was undervalued when we started the day or when we closed yesterday. But we'll always look at where the value is, and we're delighted to have bought back well over a billion shares at GBP 1.30. It must be what, 1.2, 1.3, whatever the number is, and created quite a bit of value there in the capital appreciation, but also in terms of the dividend stream that we would otherwise have been paying.
But the first point we look at a buyback is to say, do we have surplus capital that we're not confident that we can deploy? Or do we have, I don't know the right word, but like an unexpected gain. So there was I can't remember when it was, it was a couple of years ago, where we upped the buyback by GBP 500 million at the last part of the year. That's because our performance in trading was beyond anything that we expected, and we looked and said, "Okay, we've got a bunch of ideas, we've got a bunch of capital, but we really didn't expect that." It must have been 2023 or something, and so we just stuck that into the buyback. So if we have surplus capital, then we'll, we'll look in there.
And I think, I think of it first and foremost as being a way, an efficient way to return capital to shareholders. It's not to say we ignore the share price, but I think if we had surplus capital and I went to the chairman and said, "I think our share price is a bit overvalued," like, if I was the chairman, I'd probably think I might need a different chief executive because if I look and see the share price is overvalued, like on a structural basis, that means that I've run out of ideas. And so I think that... I, I think we're materially undervalued today based on what I can see.
But I also think that the capital we've got on the balance sheet today can be invested to create more value for shareholders by delivering that value than it will be by buying back shares. If a number of these things that we've spoken about don't materialize, then the capital we've got in the balance sheet today, we might not have as many ideas, therefore, we might say, "You know what? We're gonna return some of that to the shareholders." But what we're not gonna do is on a daily basis, take a view on the price, and I'm not gonna tell you where I think the trigger price is. I will tell you, I think we're undervalued today. Excellent. Ajay, you don't have another four questions, do you?
It was more just kind of Ajay Patel at Goldman Sachs. So it's more just thinking about those nuclear sites, and it's a little bit far along the line, but at some point, there is a point where these assets close. And just wondered what the development options are outside of being nuclear stations. As in, I know you've got the SMR opportunity, but you know, you have connection, it's secure, there's a lot of opportunity for repurposing in some way, and that was very much a debate over the last quarter. So yeah, anything you could give us there, that'd be helpful.
You'd think so. It's no coincidence that the first anticipated deployment of AMR technology is at Hartlepool, where we've got a 1.2-gigawatt power station that at the moment is due to close in 2028. As I say, I think it will go into the early 2030s. So you've got a good connection, you've got a highly skilled workforce, and therefore, you've got the conditions to build a power station. I think if you look at nuclear, the X-energy stuff we're looking at is 80-megawatt reactors. They're quite small, you could deploy them. Really, their optimal deployment is in a 4-pack, so a pack of four, 320 gig, 320 megs, sorry. And so theoretically, you could put them anywhere. But the reality is, I think that you find...
I think the U.K. is quite neutral on nuclear, and I think if you live in a community that has nuclear power, like if you live in Ayrshire, where Hunterston is, they would love, I think, nuclear power stations down there because they've been there, been there for 50 years. They know it's safe, well-paid jobs, et cetera. But I think if you go to a greenfield site and say, "You know what? I'm gonna build a nuclear power station here," you're probably gonna have some problems with the local communities. And so I think that the natural use for existing nuclear sites is to deploy nuclear technology. But if you can't, then... So if the question is, could you build a CCGT at Hartlepool and use the 1.2 gig connection? Absolutely. You just have to make sure that the... 'Cause there's a lot of work that goes.
I mean, when you, when you get to the point of decommissioning your nuclear power station, like Hunterston is still taking on apprentices. There are people that will work for their entire working life on decommissioning that power station. So you just got to make sure you've got enough room, enough land around it. But yeah, these are valuable connections. Existing grid connections in the system, when you've got number, a number of years, of a, of acute, they're certainly valuable. The question when you come and look at the project management is what's in the critical path? So if you can't get a turbine for five years, how do you... You kind of have to, have to order things in advance, but they, they, they certainly have value, hundred percent.
This one was just for Russell. So sort of expanding on Dominic's point, the GBP 1 billion of the headroom that we were talking about earlier, by 2028. So if you have a target of GBP 2 billion by 2030, and we're expecting the mix of the business to improve, and 1x was a number at 2028, then could we be talking an additional, you know, GBP 1 billion-GBP 1.5 billion by 2030 of extra headroom? Just thinking how we should be thinking about that risk profile and how it affects those numbers.
So I think that for now, we stick to the waterfall chart I gave you last year for the journey to 2028. But, you know, rest assured, Chris is pushing us all hard to do better than that, and if that happens, there'll be more flexibility all around for everything that's on that chart. 2030, a combination of the transformation program, the continued growth of the assets that we're investing in, as well as new investments that might come through that time. Of course, it's going to give us more flexibility, and that can either be for new investments or greater returns. So that's one of the reasons today we wanted to give everybody comfort that there's a journey beyond 2028, and it's a positive journey.
Fraser, any questions online?
Yeah, we've got a few. I will, there, there's a couple we won't get to, so, the IR team will come back on those ones. But, if we can start, I'll combine a couple of different questions on retail. So we've seen retail customers growing over the course of the last few years, but then down in the second half of the year, you made some comments about the strategy there. Could you just elaborate on what the go-forward strategy is around the retail, particularly energy supply customer base? Are we trying to grow customer numbers, shrink customer numbers? What, what's the story there? Then the second piece is just around the sort of economics of different tariffs. Probably a question for Russell.
What assumptions do we have around the share of regulated retail tariffs versus fixed rates? And then the increasing demand from B2B customers, the growth in the B2B business, what are the underlying drivers there, and how does that impact unit margins?
So look, customer numbers, it's clear the strategy is to maximize the value from that business. We pulled back on some of the customer acquisition costs or activity last year, and in part, that was because we didn't see the value, and we have reduced our spend at the moment as well. We're not going to chase poor business. So the strategy... Customer numbers used to be a great proxy for value. I'm not sure they're as good a proxy now. And so we're just taking a pause and looking and saying, "With our new customer lifetime value model, how do we determine how active we want to be in the market?" We're not gonna chase numbers so we can say we grew customers.
But I wanted us to show that we could grow customers in all of our businesses before we said, "Okay, now we're going to maximize the value." Because if we hadn't, I think there would have been a credibility issue. It would have looked like we were saying, "You know what? We can't grow customer numbers, therefore, we're going to pretend we've got a different strategy." So it's all about maximizing the value. Russell will obviously answer the economics and the tariffs. And the B2B growth, I think that's something that's maybe a little bit underappreciated. Matt Wood, who runs that business, is sitting in the front row just now. When I joined the company, that was a GBP 2 billion revenue business with GBP 40 million of profit. It's now a GBP 4 billion revenue business with GBP 100 million of profit.
It is the growth in that has been quite substantial, and we think that we can continue to grow our position. And we take... Again, that's where we take value over volume, because when I joined, we did large I&C customers. The margin on large I&C customers can be 1%, the gross margin. You don't need to do much to lose your gross margin and end up losing costs. We don't really do large I&C customers anymore. We do smaller customers where the margin is higher. There are the odd I&C customer that have actually done through Cassim's business. Because if you're a large I&C customer, and energy is 10%, 20%, 30%, 40% of your cost base, you are very sophisticated when you're buying. And so if they want to buy from us, then they'll deal with our energy traders, who are also quite sophisticated.
That's not to say Matt's not sophisticated, but if you're dealing with somebody calling up from the local corner shop or somebody calling up, they're spending. We had a contract in Ireland with an aluminum smelter. They were spending EUR 350 million a year on electricity, and I think our gross margin was less than EUR 1 million, and we just stopped it. It just made no sense for us to take that risk. So on the B2B side, we have been pursuing value over volume, and that has doubled the revenue and doubled the profit, or more than doubled the profit. And that's similar to what we're going to do, I think, in the B2C space. But we would expect to see continued growth there, but we're not going to grow in...
We're not going to go after the revenue. We're going after, people say, turnover for vanity and profit for sanity. I would follow that logic. Russell, what are we going to do in the fixed price tariffs?
Yeah. So just, I mean, when we were in the energy crisis a few years ago, nearly all of our customers in the retail supply book in the UK were on the standard variable tariff. The dynamic has changed as we expected in the past couple of years. So we were 25% on fixed-rate tariffs in 2024. That moved to 32% in 2025. So that does have a dampening effect somewhat on margins. We'd included that in our guidance and our expectations for the business. It's a competitive business, and as Chris said, we will not be chasing unprofitable tariffs or customers.
Excellent. Any last questions? I'm just conscious that it's 11:10 A.M., so-
I think we can-
No pressure.
Deal with the-
No, no, if there's any questions that have not been asked already that you want to-
There's a question around two questions. One around guidance for 2026. 2025 consensus came down to an extent through the course of the year. 2026 guidance is we've obviously pointed out a couple of areas where people need to adjust. What confidence can we give that the numbers are not going to drop further through the course of this year, and particularly around the optimization outlook? What gives us confidence in GBP 250 versus about GBP 200 last year?
Well, look, we give guidance on what's in front of our face and the analysis we can do today. Centrica Energy, we can see the positions we have, we can see the capital we've got, placed, and we can look at the markets, and I think that 250 number's a good guidance for today, and that's the same as the rest of the businesses. There could be some volatility in the infrastructure businesses, or in the retail businesses. That's why we have ranges. But, I think, the slide 14 that I gave you today, I think is a good, good proxy for 2026, as far as I can see.
Like every good sell-side analyst, I will, I'll try to squeeze in a third one, which is-
You're not a sell-side analyst.
Taking my inspiration. Performance in services was very strong during the year. Can we elaborate on the progress that's been made and what gives us confidence in getting that business back into kind of teens, low teens, EBIT multiples, margins?
Yeah, look at. So I think a lot of it is, as we described in, about boiler service, boiler installation, for example, is looking at our processes and seeing what is it that's working, what do we need? So example, in boilers, we had a rule that if you had a boiler that was installed, that was above the ground floor, we'd put a scaffold up. Now, if you get a Sky TV dish installed, very rarely do they put a scaffold up. They put a ladder up, but they drill a hole in your wall and attach the ladder to the wall, so it's still safe. And if you say you can't drill a hole in the wall, they say, "Well, you can't have a satellite dish." And so we were putting up scaffold, which is expensive.
We were then leaving it up, which I thought was a security risk, rather than putting a ladder up. So we changed that. We will put up scaffold where we have to, but it's not a hard and fast rule. And it's these really small things, and Gary has got the team looking at this, and we've got some internal people that are, you know, probably the bane of Gary's life because they're fiddling about trying to find all these different things, and these things all make a big difference. We're looking more at things like, for example, if you think about our installations team, we do boilers, we do heat pumps. We're the biggest installer of heat pumps in the U.K. But we do rewires. Now, how many people would think, "I need my house rewired, I'm gonna call British Gas"?
They probably don't. So there's some more marketing for us to do to tell people we've got a bunch of electricians that are out doing rewires. A rewire of a reasonable size house is best part of GBP 10,000 or something. So there's a lot of... when we tell people what we do, we get... The demand is there because our competition is somebody in a white van, and some of these people are absolutely brilliant, but everyone's got a story about, like, a bad builder or a bad contractor or something. You know where we are. You don't have to worry about whether you're gonna be able to find us. You know where British Gas is. So the opportunity is huge. I mean, I think the growth opportunity for us in this business is absolutely gigantic.
We wanted, however, to get our operations in the right place. We were letting our customers down. The reschedule rate has gone down massively, like 20-odd% a few years ago. It's 4% now, and we're meeting the customer promise. 80% of customers that call us by 11:00. If you call us by 11:00 with no heating or no hot water, we'll be there same day. So 80% of our customers, we're meeting that for. Now, what we did when we brought it in was we said, "You don't have to be a British Gas contract customer. You just have to call us." So it was an operational-led decision.
Now, it's getting more commercial because if you don't have to be a British Gas customer, but we'll go out the same day, well, why would you be a British Gas customer? So those customers that are contracted with us will get preference. Those customers that have got a subscription, I think, I don't know, Gary, what, 100,000 subscriptions or something now, or more? They'll get preference. So we've got the operational discipline, we've got the operational performance, we've got the brand, we've now got more commercial nous, and this is... We announced last week 500 new apprenticeships. You know, the question I'm looking at is to say, well, either we've got a few hundred electricians, do we just go out and hire a few thousand electricians on spec?
Probably a bit too much, but it's certainly not that we just hire another 5 or 10 or 15. So, and again, this is where, going back to the question on how much of the cost savings will come into the, will, will go to the shareholders. There will be things that we have to lay out cost in advance, and it might be this, to say, "Look, we're gonna go and hire 500, 600, 700 electricians because we know the demand's there," but the demand is not gonna come on day one. We're gonna have to do the marketing. We've got to spend more on the marketing. So I'm very confident about that business because the operations are now very strong, and there's a very good chief operating officer in there, and she's making improvements every single day.
I mean, you were with the team yesterday in Cardiff. I think, Gary, you've seen some of this stuff, making improvements every single day. So we know the demand is there. We've just not been able to satisfy it. Now, we can satisfy it, and we just got to to seed some more, some more money in there. So, I'm, I'm very confident that we'll see growth. I'm very confident, and I can say as we close off, 'cause I'm assuming you don't have any more questions and you've got your sell-side analyst persona on, but very confident in our ability to deliver what we said we're gonna deliver in 2028, what we said we're gonna deliver in 2030.
If you look, if you look at what we've-- we're doing, you know, we said a while ago, we're gonna sell out to the North Sea, and we're gonna put that money into electricity assets. We've just sold our last North Sea asset. So we, we do what we say we're gonna do. We're investing in contracted and regulated assets. I think some people probably at some point thought this Sizewell C thing's never gonna happen. I thought that on occasion as well, sometimes in the meetings, but it took us probably the best part of three years. We've now got, I think, a phenomenal investment opportunity. We have earnings in 2025 relating to Sizewell C. How much are we putting? GBP 400 million, GBP 450 or something in November?
Yeah, 380.
380. That look means we didn't disclose that number, so I'm in trouble now, but, you know, so we put best part of GBP 400 million in there, and we're making a return on that. That will be, we'll get a full year return in 2026. Some of these investment opportunities are huge. We've worked very hard with the government, and we saw the consultation on gas come out, which you could argue has got parts of it written with Rough in mind. And so some of the stuff that we've got does take years to develop, and some of it is binary. You know, the government says yes, the government says no. You get planning permission, you don't. You get a regulatory model, or you don't.
That's why the discipline is so important for us, but it has to come with patience on our side so that we don't do anything daft. But, you know what? We lay out the GBP 1.7 billion in 2028, the GBP 2 billion in 2030. The fact we think we're gonna double our EPS or better by 2030 is something that we are confident in. It's not easy, and we've got a leadership team here and a lot of our colleagues who I think are both invigorated by it and sometimes exhausted by it because it's hard work. It's hard work every single day, but we absolutely have the opportunities there. We've got the people, we've got the market positions, we've got the brands, we've got the finances, we've got the balance sheet, and we've got confidence.
So sorry for keeping you, 'cause that's been an hour and 40. This reminds me of the old Centrica things, but we would present, and then previously, we'd present for about an hour and 15 minutes, and you'd only get about half an hour for questions the other way around. So, so thank you very much for coming, and we'll see you again in July when we present our first half results. Thank you.
This presentation has now ended.
