Good morning, thank you for joining OSB Group's 2025 full year results presentation. This morning I'd like to take you through the key highlights for the year, provide an update on strategy that we presented back in March last year and insights into the macro drivers that are supporting our business. I'll hand over to Victoria for the financials in detail before returning to summarize the outlook. Starting with a high level view of the business, as I said to you back at the half year, we're on track. A year ago, at our investor update, we set out our strategy to remain the number one specialist lender and also provide short-term guidance and medium-term aspirations. I'm very pleased that we have delivered in line with our 2025 guidance, the first year of our transition period.
As you can see on the right-hand side, we have achieved all of our targets, and we are building well towards our medium-term plan. This slide highlights our three familiar themes that demonstrate progress against our strategy and continues to reflect our current transitionary phase. Firstly, we set out at the Investor Day our optimized lending growth plan, and we've successfully delivered against this during the year. Net loans grew at 3.2%, and that reflects our discipline in maintaining attractive ROTEs in new lending, supported by particularly strong growth in commercial lending. Our medium term loan book optimization strategy is reflected in the 53% growth in originations from higher yielding segments that we delivered in 2025. As expected, net interest income has reduced compared to 2024, and Victoria will cover this in more detail later.
The strength of our underwriting expertise applied across all of our lending activity is demonstrated in our low loan loss ratio. Secondly, we maintain cost discipline and efficiency while creating capacity for investment. Our culture of challenging costs has contained core cost growth to only 0.8%. The cost to income and management expense ratios are in line with our expectations, and these reflect the impact of our transformation expenditure as we invest in the future of the business to deliver efficiency over the medium term. Delivering attractive ROTEs and capital returns to shareholders continues to be our primary objective. The GBP 383 million of profit before tax translates to an ROTE of 13.7% and a TNAV per share of GBP 5.79, up from GBP 5.44 last year.
Our commitment to rewarding shareholders is underlined by the 5% increase in full year dividend. In addition, I'm delighted to announce a further GBP 100 million share buyback program for 2026, and we have now completed successfully on the 2025 buyback program. In summary, I'm pleased with our progress in 2025 and our delivery against targets in the first year of our transition period. Next, I'll take a moment to remind you of the plan that we presented this time last year. Through the planning horizon, we'll leverage our core strengths of high quality and meaningful broker relationships, deep product and credit expertise, and a track record of delivery at scale. All of this will be supported by and accelerated by a significant tech transformation now entering the fourth year of our five-year plan.
That will take us ahead of our competition and will enable us to grow more efficiently. Combining this transformation with our key strengths will enable us to drive growth in our savings and lending platforms, accelerating our diversification into higher yielding asset classes, delivering an optimized lending mix and with a more favorable cost of acquisition. In the medium term, this will cement our position as the leading specialist lender, delivering improving net interest income, positive cost drawers, and most importantly, delivering growth in ROTE, our North Star. Next, I'll take a look at the broader market landscape and the key developments we've seen during the year. Beginning with interest rates. We're pleased to see reductions in bank base rates, including the most recent cut in December. Lower rates should stimulate demand for borrowing across our lending segments.
While we saw some volume growth in the year, we expect that any further reductions in rates from here should encourage more buyers back into the market. Volume across the buy-to-let market gradually recovered over the year with a pause in the run-up to the budget. Fundamental indicators for professional landlords continue to show strength, including a 4% increase in rents recorded during the year to December. The chart on the right-hand side illustrates the level of competition we're experiencing in buy-to-let. We've continued to see elevated levels of competition, particularly from current account funded high street competitors. However, as you can see across our brands, we've continued to exercise pricing discipline, playing to our strengths of lending to professional landlords whose complex needs cannot be met by the high street.
Looking to the lower half of the slide, opportunities remain attractive in our target higher yielding sub-segments. Bridging finance has seen good growth with the size of the market increasing by 52% year-on-year. Commercial property has also performed well, delivering an average returns across the market of 7.1% in the year, underpinned by a balance of capital appreciation and growth in rental returns. Having looked at the market, I'll now turn to the group's performance and levers for successfully delivering our optimized lending strategy. We're starting from a position of strength with trusted relationships established with over 19,000 brokers across the country who have access to a sales team of more than 100. These personal relationships, supported by technology, give the group a clear competitive advantage in winning business.
We provide a one-stop-shop to support brokers in finding solutions to often complex customer requirements. That's an arena in which we excel. We continually evolve and innovate our product set to target the areas in which we want to grow in line with our credit appetite, whilst ensuring we meet and exceed customer expectations. To give just two examples, during 2025, we launched a range of new mortgages and implemented criteria adjustments to broaden the appeal of our residential products under the Precise brand. Whilst in bridging, we expanded our dedicated sales team and enhanced our product offering. Our credentials as a leading specialist lender are demonstrated by the stats at the bottom of the page.
Professional multi-property landlords represented 92% of the Kent Reliance buy-to-let completions in 2025. We're continuing to attract customers who trust us with their complex needs, evidenced by a 23% increase in HMO completions. Our strong broker relationships, together with our agile, targeted approach to product innovation, supported by technology, allows us to actively balance the growth and composition of our lending book. We are very disciplined in how we choose to grow, balancing return and opportunity to optimize our book. As you can see here from our graphic equalizer chart, we have delivered as we said we would within our risk appetite, adjusting the mix and the returns to optimize across the loan portfolio, pursuing growth in a focused way. I'm pleased with the progress we've made in adjusting the mix of the book with step ups in the pace of originations across our high-yielding sub-segments.
Taken together, I'm pleased with the execution of our optimal growth plan. This considered, disciplined approach delivered loan growth of 3.2% in 2025. We're anticipating a similar rate of growth in 2026. The successful delivery of our plan is underpinned by our transformation program. I'm pleased that we sustained the momentum in 2025 as we completed the third year of that transformation program. The foundations are in place. We're rolling out functionality at pace. In savings, we've continued to launch more products on the new platform, including joint accounts and easy access. We're pleased with the favorable response received from deposit customers who particularly value the ability to self-serve across 13 different product features, removing the friction from processes that previously would have required contacting us by telephone.
On the lending side, we launched our new platform starting with buy-to-let mortgages, and this has been really well received by brokers, appreciating the enhanced functionality, streamlined processes, and significantly accelerated timelines. Alongside the new platform, we launched the Rely buy-to-let brand, a first step in simplifying our mortgage offering. Rely creates a buy-to-let powerhouse, drawing on the same expertise and experience that our broker partners are already familiar with. Excuse me. The combination of the new Rely brand on the new modern lending platform has been a game changer for our operations and the quality of engagement with brokers. We're now able to deliver agreements in principle in under 10 minutes and mortgage offers, in some cases, in less than 2 hours. This marked improvement in turnaround times is resonating strongly with brokers who value fast, efficient case progression for their customers.
Whilst our enhanced data flows help support strong credit risk decisions for the more complex cases. As of today, over 40% of our mortgage applications are now processed on that new platform. We've successfully delivered against milestones and importantly delivered within budget. Looking ahead, we remain committed to sustaining the momentum we built over the past three years. In savings, we'll continue to expand our product offering under the Kent Reliance brand on the new platform, and we'll complete the migration of all existing Kent Reliance accounts, of which 40,000 have already successfully been transferred. We will also move the Charter Savings Bank operations in-house and onto our new platform. In lending, I'm excited about the opportunities ahead as we expand the platform into other lending lines.
Sorry, bringing the operational efficiencies, commercial benefits, and enhanced customer and broker experience that we've seen so far in buy-to-let to the other segments in which we lend. The development of residential mortgages on the new platform is well underway and will launch later this year under that Precise brand. New cloud and data structures, a key element of our transformation position, positions as well, sorry, to benefit from the use of AI and advanced analytics as we successfully piloted new AI tools to prevent fraud. Our transformation program is now fully integrated into our day-to-day technology operating model under the leadership of the group CIO and the group COO is focused on embedding the functionality being delivered into our group operations teams. The program is on track and on budget.
The business is already benefiting from the investment, and as the rollout continues, we'll keep you informed of our progress and the value it's delivering for both the business and our customers. We look forward on giving you more details of this at our buy-to-let spotlight session, which is due to take place on the 25th of March. With that, I'll hand over to Victoria for further insights into the financials.
Thank you, Andy. Good morning, everyone. I want to start by saying that I'm pleased with these financial results that are in line with our 2025 guidance. Turning first to the P&L. Please note that these are the first full-year results prepared on a statutory basis as the final acquisition-related items rolled off in December 2024. However, the equivalent comparative for 2025 statutory results are the 2024 underlying results, as neither have any impact of acquisition-related items. Net interest income was GBP 679.4 million for the year, down 2% compared to the prior year, and NIM was down 2 basis points. I will provide more color on the NIM dynamics on the next slide. The fair value loss on hedging activities was GBP 22 million compared to a loss of GBP 2.7 million in the prior year.
The key driver behind the loss, which will reverse over the life of the swaps, continue to be the fair value movements on our pipeline mortgage swaps due to the movements in the SONIA forward curve. Administrative expenses increased by 5% to GBP 270.1 million in the year in line with our guidance, and an impairment charge of GBP 13 million was recognized for 2025 compared to an impairment credit of GBP 12.8 million in 2024. I will cover both of these items in more detail later. Profit before tax for the year was GBP 382.5 million, and basic EPS was 75.6 p per share.
For the second half of the year, net interest income increased by 4%. Profit before tax was only marginally lower at GBP 190.2 million. This outcome delivered an EPS that was up 6% to GBP 0.378 per share. NIM improved 10 basis points to 226 basis points and ROTE was 13.7%. Looking at NIM year-on-year, please note that 2024 NIM is on an underlying basis as this makes this a more meaningful comparative to 2025 statutory NIM. NIM reduced from 230 basis points in 2024 to 228 in 2025. Higher cost of funds caused downward pressure year-on-year as our savings will continue to recycle onto more costly spreads versus SONIA compared to those in the prior year.
The higher cost of funds was broadly offset by an improvement in the lending spreads as the lending back book dynamics rolled through in parallel to another year of business written at sustainable margins. We have also for the first time shown NIM excluding liquid assets, which was 267 basis points in 2025. This presentation of our NIM better reflects the performance of the underlying business. It also allows for a more meaningful comparison with our closest peers. We have provided the calculation in more detail in the appendix. This slide presents our 2026 NIM guidance and the drivers behind it. In 2026, as we continue through the transition period, we expect the same key drivers to those in 2025 to deliver NIM of circa 225 basis points the year.
As we told you last year, the lending back book dynamics will continue to influence the lending contribution to margin, which is illustrated by the upper chart. On the front book, we will remain disciplined on the pricing of new loans. The lower chart provides more context on the deposit market we're operating in, showing spreads to SONIA of the average top 10 quoted pay rates across the market for 4 key savings products. You can see that in early 2025, the average market spreads moved above SONIA, including on easy access products. This was more pronounced in the second half of the year. We can also see a widening in the cost of fixed deposits versus easy access. We saw cost of funding increase further in Q4 2025, this elevated level has persisted so far into 2026.
Our 2026 circa 225 basis points NIM guidance is based on our expectation that funding cost will normalize from today's elevated levels. We will update you on the cost of funding progression over the coming quarters. This slide presents an overview of our strong funding franchise. The group remained predominantly funded by retail deposits sourced under our two well-established brands of Kent Reliance and Charter Savings Bank. As at the 31st of December, retail deposit balances were GBP 24.3 billion, an increase of 2% from the prior year, supporting loan book growth of 3.2%. The remainder of the group's funding was broadly unchanged in the year and came from debt and wholesale issuances, providing diversification and duration to our funding requirements.
In addition, the group continued to utilize the Bank of England's funding facilities, having fully repaid its TFSME drawings in September. Our index long term repo balance as at the 31st of December grew to GBP 1.5 billion. The makeup of the group's total funding is shown in the two pie charts on the right. We continue to optimize our funding mix and the proportion of our fixed rate bonds versus easy access accounts continue to reduce compared to 2024. Moving on to costs. A key part of our plan is that we tightly manage our cost base to allow us to invest in the transformation program. In 2025, the administrative expenses or expenses met our guidance and the transformation spend was on target. This and the following page highlight our cost discipline and transformation spend.
Expenses were GBP 270.1 million, up 5% compared to 2024. Despite a higher level of inflation, our core U.K. and India costs increased by only 0.8% compared to the prior year. The main driver of the growth was further investment in the transformation program with a GBP 9.4 million increase in the P&L charge compared to 2024. On the next slide, we provide more detail on our spend to date. The cost to income ratio increased to 40.4% from 38.7% in the prior year, and the management expense ratio also increased to 90 basis points from 85, both in line with our expectations.
Looking forward, we will maintain strong cost discipline. For 2026, we expect group expenses of circa GBP 280 million. We expect that core costs will increase at no more than the rate of inflation. The investment in the transformation program will continue to increase in line with our plan. Andy outlined earlier key milestones that we've achieved in our transformation program since we presented it to you at the investor update last year. On this slide, we summarize our spend in the last 3 years as we enter the final 2 years of the program with around GBP 85 million of investment to come. There is no change to our expected total spend on the program of circa GBP 190 million until it completes in 2027.
This slide presents our progress against the optimized lending growth plan, combined with a disciplined approach to risk that we announced at the investor update. The net loan book grew by 3.2% in 2025, supported by GBP 4.7 billion of originations, an increase of 19% compared to 2024. Originations in the higher yielding sub-segments of commercial, asset finance, residential development and bridging increased by 53% from 2024. Higher yielding segments made up 12% of the total loan book versus 9% in 2024, and consequently, buy-to-let accounted for 68% of the book, remaining the largest part of our lending. Our guidance for 2026 is that we expect net loan book growth broadly similar to that achieved in 2025.
This slide provides a waterfall of the movement in the impairment provision in the year, as well as the credit quality metrics of our secured loan book. As you can see on the chart, the total ECL balance sheet provision reduced to GBP 123.6 million as at the end of 2025. The larger releases comprised model enhancements and PMAs and the positive impact from borrowers moving through the ECL stages. These were partially offset by increases in provisions for accounts with arrears of three months or more, new lending and other charges. Moving on to arrears, for 2025, the three-month plus arrears remained unchanged from 1.7% at the end of 2024.
As you can see on the right-hand side of the page, our balance sheet total coverage ratio reduced to 47 basis points, and our provision balance was eight times higher than the average yearly write-offs in the last five years. We remain comfortable with our risk profile and our impairment provisions. We show here that if we were to move to our IFRS 9 weighting 100% to the downside scenario, the ECLs would only increase by GBP 25 million. Finally, as you can see at the bottom, new buy-to-let lending interest coverage ratios remained high. Next, capital. 2025 was another year of strong capital generation of 150 basis points, and the group CET1 ratio remained robust at 15.8% at the end of December.
Our profitability in the year increased the ratio by 2.3% and supported growth in the net loan book and the ordinary dividend. Before the effect of the GBP 100 million share buyback program announced in March 2025, the CET1 would have been 16.6%, and the share buyback had a 0.8% impact on the ratio. With greater clarity over the Basel III.1 rules and our confirmed MREL status, the board set a new CET1 ratio target in the range of 13%-13.5%. The group continues to generate enough capital to support loan book growth and a progressive dividend. The board remains committed to returning excess capital to shareholders as we progress towards our new CET1 target post Basel III.1.
On this slide, we laid out the movement in our net loans and RWAs over the last two years. You can see that as the loan book grew by 3% in 2025, the RWAs increased by 5% as more lending came from higher yielding sub-segments which attract higher risk weighting. The loan book mix accounted for a GBP 0.5 billion increase, as shown in the right on the chart. We continue to expect that the implementation of Basel III.1 rules as written would reduce the CET1 ratio as at the 31st of December 2025 by 1.3% as a result of a 9% uplift in RWAs. This is compared to just over 1% as at the 31st of December 2024.
The increase in impact on the CET1 ratio is largely due to the growth and change in the mix of the group's loan book. This slide presents the group's capital resources and capital requirements. The group is well in excess of the minimum regulatory capital requirements. The group's resolution strategy for MREL was changed to transfer, the minimum regulatory capital requirement now also equals the group's MREL requirement. You know, the group currently has GBP 700 million of MREL securities, and the change in the MREL resolution strategy should start to positively impact ROTE from September 2027 when the first of the securities reaches its call date. We continue to evaluate the optimal approach to our existing MREL securities.
Finally, on this slide, we remain focused on ROTE, and we continue to expect low teens ROTE in 2026, mid-teens in 2027 and 2028, increasing to the top end of mid-teens in 2029. I will now pass back to Andy.
Thank you, Victoria. In summary, today we presented a resilient financial performance combined with good strategic progress. Our headroom to grow has been demonstrated by our 3.2% net loan book growth, and we've continued to shift the portfolio mix to optimize returns. There has been solid capital generation with attractive shareholder returns as we increased our full year dividend per share by 5% and announced that further GBP 100 million share buyback. Finally, turning to the outlook. There was upward pressure on funding costs in H2 2025, and we have to date been able to compensate through loan book performance, producing strong asset yields as evidenced in our 2025 full year NIM.
It is very early in 2026, and whilst we've seen sector noise this year on funding costs, our assumption is that the cost will begin to normalize through the year and our NIM guidance of circa 225 basis points is given on that basis. Our focus remains laser-like on ROTE, and we continue to expect low teens in 2026, mid-teens in 2027 and 2028, increasing to the top end of mid-teens in 2029, driven by the successful execution of our strategy, capital optimization, and the MREL instruments reaching their respective call dates. With that, we will now hand over to Q&A. We'll start by taking questions in the room, and there are microphones, I think, to be passed around, and Ben Sanders immediately gone up. Then we'll go over to people on the phones.
Ben Toms from RBC. Thanks for taking my questions. Firstly, on your ROTE guidance, you've reiterated your 2028 ROTE guidance of mid-teens. Since you struck that guidance, we've had two positive pieces of news, or tailwinds in relation to the ROTE, the MREL story, and a lower capital base. Is the right way to think about your 2028 ROTE guidance that you're increasingly optimistic around hitting that number, or are there other headwinds which will offset those tailwinds that we need to think about? Secondly, on your 225 basis points NIM guidance, you made the point twice that it's predicated on elevated funding costs falling back down to your planning assumption. If they don't fall back down, what would be the headwind to your NIM guidance and what offsetting levers do you have? Thank you.
Okay. Thanks, Ben. I'll let Victoria talk to the NIM point. But I mean, on ROTE, you know, we've reiterated the mid-teens for 2028, but I think we've slightly upped in terms of 2029, saying the top end of mid-teens. I think what that tells you is that we can see the clear path to rising ROTE as those MREL instruments fall due and fall away from the balance sheet because they're quite a significant cost. Obviously, you know, one of the board's key drivers is to make sure we're returning adequate capital to shareholders and therefore optimizing the capital down to a sensible level of CET1.
You know, all things being equal, given what might or might not be going on in the macro economy, I think what we're setting out here in our guidance is that we're optimistic about that glide path towards that sort of high end of the mid-teens. On the NIM, Vic.
Yeah. I mean, on the NIM, as we stand today, you know, we're comfortable with that circa 225. You know, that is predicated on the same three drivers that we've talked about. we sustainable front book margins. we know that the back book will continue to roll through. it is the cost of funding. In terms of the rate that that is predicated on, we are looking at an average blended front book and retention of SONIA plus 30, and that is lower than current market levels, naturally higher than last year. we do expect that to normalize over the year, and that is the average level that we're saying blended for the year.
In terms of offsetting levers, obviously, as we came in, we set out 2 years of saying, "Look, we have a lot of things running through the P&L, and we expect those all to offset to that circa GBP 225." You know, the back book has been resilient over the last year and probably performed better and contributed more than we'd originally anticipated. We are assuming that will continue. Within the cost of funding, we have got our transformation deliveries. We are looking at, aim, you know, to refine further our cost of funding and improve it through faster repricing and more product diversity. You know, we are very focused on those drivers within the P&L.
Yeah, and then front book, you know, we do manage the business from returns, looking at where we can optimize that value, and we will continue on with that route. I mean, it's early on in the year and we will have to see how the market plays out. But we are obviously very focused on optimizing and delivering to our low teens ROTE in 2026.
Grace. Thank you.
Grace Dargan from Barclays. Maybe just picking up on NIM again, thinking about the trajectory in 26 then and really out beyond. Because I guess if now you're talking about same guidance, but a normalization of those deposit costs, are you pointing to more of a pickup towards the back end of the year and therefore maybe a better base to start from in 27? Secondly, I guess the point on glide path around capital, how quickly do you think you can get to within operating within the 13%-13.5% target? Should we be thinking of that by 28, or is that a longer glide path? Thank you.
Okay. Do you want to talk about NIM, and then I'll touch on it?
Yes. Yeah. I mean, as we look out, I suppose we're not guiding at the minute on 2027. You know, those 3 drivers, as we noted in the slides, you've got the 2026, the last high margin book rolls off. You know, in 2027, we have got 2027, 2028 is with the lower margin, and that will roll through. I mean, I would say we are expecting that normalization of cost of funds. I mean, at the minute, you know, if I compare to what I thought in December, to what I thought now, to what I thought this week, you know, there is a lot of changing, you know, a lot of discussions we're having about base rate reductions and cost of funding.
I would say it's extremely hard to call sort of 2026 at the moment, let alone 2027. We do expect through transformation and just, you know, the December base rate rise really just wasn't passed through to customers. You, you sort of think that has to normalize over the year. Yes, we are expecting it to temper down, but in 2027 we still have those drivers. We, you know, we're not guiding on that yet, and I do feel we need to wait 'til we're a bit further into the year, you know, to start to understand where 2027 may land.
Yeah. I mean, on the capital glide path, and clearly you probably don't expect me to give you a date at which point we're going to arrive at 13 or a quarter or something like that. I mean, the board are committed to that. I think we consider that to be, you know, a sensible target for CET1, higher than we see in some other peers, but we think sensible given all factors. Clearly, we've got to get through Basel III.1 at the beginning of 2027.
Also there's a bit going on from a macro perspective, and you've always got to have a weather eye on your capital ratios as to what might or might not be happening from, you know, unemployment or inflation indeed driven by the current problems in the Middle East, et cetera. You know, the board will continue to monitor economic signals, and what we're doing in terms of book mix and growth and opportunity, of course. Once we're through the other side of Basel III.1, that glide path is eventually where we want to get to. I'm not saying we're going to take years to get there, but clearly we have to manage capital carefully, and kind of understand that in the context of the broader market. Yes.
Good morning. It's Jonathan Pierce from Jefferies. Two questions. The first is on deposits. The margin on the deposit stock, are you able to tell us where that is at the moment so we can compare it to your sort of SONIA plus 30 for the new business coming in this year? Connected to that, can you give us a sense of your appetite for using ILTR? Because obviously that is significantly cheaper than the deposit cost that you're paying at the moment. Obviously you've ramped that up over the last 6-12 months, but GBP 1.5 billion, could that go appreciably higher than that? The second question's on capital. Foundation IRB on the mortgage book, what sort of timeframe do you think we should be thinking about for that?
Is it likely to be a speedier process than the more advanced IRB type approvals? I don't know if you can give us a sense of how big that might be. Are your ROTE plans further out to 2029 predicated in any way on getting those FIRB approvals on mortgages? Thanks.
Okay. Do you want to take the first two, and then I'll talk about IRB.
Yeah. I guess on deposits, Jonathan, I know you asked that question at the interims. I guess we are looking at those disclosures, but it's not something at the minute that we are releasing in terms of the stock levels. In terms of our appetite for ILTR, as you say, yes, it is. We do see it as within our, you know, within our tools for funding. Yes, we did choose to use more of that in Q4. I guess we see it as more an ability to manage peaks and troughs. I, you know, we certainly do look at using that. As you say, GBP 1.5 billion. We have multi-billions of collateral with the Bank of England, so we have those options.
We will continue to use it. You know, as we look forwards, it's not so much, I think, just holding a static number. It's going to be, as we saw in December, suddenly you have a late base rate reduction, you have the budget. You know, we would say, "Look, we'll just take some," and that's what will see us over the 6 months as we manage through peaks and troughs. Yes, it's definitely something that we see in our sort of armory of funding that we will use going forwards. I wouldn't comment on, you know, how comfortable or, you know, how many billions will we get, 'cause it's one of those live conversations we just manage as the peaks and troughs go through.
Yeah. That's a really good point. I kind of view the repo scheme as a bit of a smoothing tool more than a kind of massive part of the funding that you do. You know, when retail is a bit more expensive than you want it to be, you'll make use of it. When retail comes in at a better price, you'll use less of it. Clearly we have encumbrance limits around how many assets we want to pledge with the bank as well. No, we don't print the stock number. Our retention pricing is less than front-end acquisition pricing. It gives you some sense about how the book might be positioned.
On the foundation IRB, interestingly, I was actually having a conversation with the regulator about that very topic on Monday afternoon, they still haven't given the industry absolute clarity around size of the prize versus the effort equation. That's the one that my CRO and team really want to get into with the regulator. You know, we have been running the organization as an IRB firm for some years now. You know, we run all the models that you would have to do for that, and we govern the organization in that way. We need to really and then which of the two routes we want to go down.
I think it's fair to bet we want to go down one of them, we do need that clarity from the regulator before we make the decision. The board will review. That will drive us down a particular route. There's also that conversation with the regulator, which again, I started with them or had with them on Monday, which is, look, if we go down in kind of door opener into then a full-blown application, once you've got resources to take us through that's another question we need answered before we commit one way or the other.
You have.
No
that assumption.
No, no. None of our assumptions are based on They're all based on being standardized under Basel III.1.
Okay. Thank you.
Open questions coming in on the phone.
We currently have no questions. Sorry. We do have one question come through. Our first question comes from Edward Firth from KBW. The line is open, Edward. Please go ahead.
Thanks so much. Can you hear me okay?
We can. Thanks, Ed. Yeah.
Great. Yeah, I just have two questions. You mentioned the plan was struck on a average funding or deposit cost of SONIA plus 30. Could you tell us roughly what it's running at now? That would be the first question. The second question was, I think in the past, last year, you were talking about front book margins at around 240 basis points, or you were writing business at 240 basis points. Could you tell me roughly what that is now? Thanks so much. Just those two questions.
Yeah.
Thanks.
Thanks, Ed. Let me talk about front book margin briefly. We always said that front book margin blended across the kind of originations that we're writing is actually somewhere between 240-280. That continues to be the case. Some months it's at the upper end of that, depending on the mix of business that completes in the month, and some months it's at the lower end, but very much in that 240-280 territory. Hopefully that gives you some comfort on that. Do you wanna talk about the SONIA +30? Yeah. I mean, the market, you know, as we showed in the chart there, it does...
I would say it's a good sort of 10+ basis points above that at the minute. If you do look at the spread though, what we are actively managing, you know, fixed rate bonds are more expensive than that easy access. It is a bit of a blend around balancing sort of fixed versus easy access, retention versus front book. I think some. You know, if you look at the best buy, we're not pricing, you know, right at the top of best buy and our blend is, I would say it's a good 10-15 above that presently.
I suppose on the just on the lending, I guess we do write obviously in our lending, you have the multi-years of we do make funding assumptions in that. Naturally we're very comfortable with the sustainable sort of front book margins and then it is how funding flows throughout the year, that, you know, would have that impact on NIM.
Great. Thanks so much.
Thanks, Ed. Any further questions, operator, on the phones?
We currently have no further questions on the line.
Okay. Well, on that basis, I'm delighted that we appear to have bored people into not being able to ask questions. Boring is good, right? 'Cause it means we, to steal a line from my learned colleague here, did exactly what we said on the tin, which was the plan. Yeah, we're on track. We've had a decent year. We'll work hard at having another one. Thank you very much for your questions. Thank you for your attendance.
