Good morning. My name is Trevor Harvey. I'm Stelrad Group CEO, and here with me today is Leigh Wilcox, Group CFO. The agenda is as shown on the slide. After a brief overview of our results, we'll have a detailed review of Stelrad's financial performance, followed by a business review. Following the summary and outlook, we'll then move on to a Q&A session. I'd like to begin with a brief overview of Stelrad's 2024 performance. I am pleased to report a continued strong performance for the business despite the challenging market backdrop. Our adjusted operating profit increased by 7.6% compared to the prior year, to GBP 31.5 million, while our focus on proactive margin management initiatives has resulted in a seventh consecutive year of increased contribution per radiator, which in 2024 exceeded GBP 20 per radiator for the first time.
In addition to cost and price management actions, we saw positive mix changes, notably in the U.K. market, where increased premium steel panel penetration, combined with volume growth in high-output conventional radiators, underpin our confidence in the long-term opportunities provided by the structural drivers of increased premiumization and the drive for decarbonization. Macroeconomic conditions remained challenging in 2024, and as a result, revenue declined by 5.7%. Return on capital employed was up 1.6 percentage points relative to 2023, at 27.1%. Those of you who attended our Capital Markets event late last year will recall that providing market-leading levels of customer service and product availability is one of Stelrad's key competitive advantages, alongside flexible, low-cost manufacturing and the Group's leadership of the European heat-emitter market. During 2024, on-time in full delivery performance in the U.K. and Ireland was an impressive 98%.
Our strong financial performance has enabled us to increase total dividends in 2024 by 2%. While we are not expecting the wider market backdrop to improve significantly during the first half of 2025, we enter the year making good progress towards our medium-term targets and remain effectively positioned to outperform our peers and deliver continued growth for our stakeholders, independently of future market recovery. I would now like to hand you over to Leigh for a more detailed review of the Group's financial performance.
Thank you, Trevor. Good morning, all. Moving first to slide six in our financial snapshot. The format consisted of that presented at our interim results, and it includes some of our financial KPIs. The four-year story continues to be consistent with that we reported the half-year. On a headline basis, despite declining revenue, there has been strong improvement in other profit and loss measures. Significantly, adjusted operating profit has increased by GBP 2.2 million to GBP 31.5 million, and adjusted operating profit margin has increased by 1.3 percentage points to 10.8%. Aided by strong profit growth and the devaluation of the euro against GBP, return on capital employed has increased by 1.6 percentage points to 27.1%.
The chart also highlights that we have proposed to increase the final dividend by 2% in line with the interim dividend increase, which reflects balance sheet strength and confidence in the Group's future growth prospects and cash-generating potential. As flagged previously, we have made an investment in working capital in the year, principally to ensure that we are well placed to respond to market demand, and as a consequence, our operating cash flow conversion is low in the year, but we expect this to recover strongly in the medium term. Positively, despite a lower operating cash flow conversion, our leverage ratio has improved since prior year, with strong profitability growth and a small reduction in net debt. Following on from this overview, we will now explore performance in more detail, starting with slide seven.
On this slide, we highlight the recent trend in revenue, adjusted operating profit, adjusted earnings per share, and dividends per share at group level. In the subsequent slide, we will examine the revenue and adjusted operating profit in more detail at a segmental level. Revenue year-on-year reduced by 5.7%. The declining revenue was due to a 5.8% decrease in sales volume during the year and the impact of the EUR devaluing against GBP, partially offset by selling price benefits. Selling prices have benefited from a positive U.K. mix and the impact of a U.K. price increase, which was applied to recover ongoing inflationary cost rises, partially offset by an adverse mix and modest price concessions in some European markets.
While sales volumes were down by 5.8% in the year, volumes were down 8% in half-one and only down 3.5% in half-two, with certain key geographies in Europe showing a year-on-year increase in volumes led by business gains. Despite the revenue reduction, adjusted operating profit has grown by £ 2.2 million, or 7.6%, to GBP 31.5 million, with a 1.3 percentage points increase in margin. There are many elements of the movement, including favorable product mix in the U.K., with the adverse side of radiators sold increasing by over 6%. Ongoing operational control, including the benefits of the Q4 2023 restructure, we saw additional volume shifted to our low-cost Turkey facility and the reduction of fixed costs in our Western European and U.K. businesses. Finally, strong ongoing margin management helped to ensure that price movements were controlled successfully.
Adjusted earnings per share have reduced versus prior year, with the comparator benefiting from a significant one-off deferred tax credit. Excluding the deferred tax credit, there's pleasing earnings growth, with improvement in operating profits only slightly offset by an increase in interest charges. The fourth chart shows the proposed 2024 total dividend of 0.0779 per share, representing a 2% increase. This chart shows how we have maintained and laterally increased earnings dividends despite the earnings reduction since 2022. A detailed income statement, which highlights the moving interest and tax, is included in the appendices. Now moving to slide eight, where we can examine the volume and premium panel mix trends in more detail. In respect to volumes, we can see the 5.8% reduction year-on-year, with high interest rates and inflation continuing to suppress both RMI and new productivity.
Positively, the Group has achieved year-on-year volume increases in Belgium, Netherlands, and Poland, driven by our sustainable competitive advantages, including our flexible low-cost manufacturing, leading levels of product availability and customer service, and a competitive position of scale. The Group premium panel penetration percentage grew slightly to 5.7%. Although overall volumes fell in line with the market, there was a pleasant increase in the penetration of premium panel products in the U.K. and Ireland, where traditionally these products are underrepresented. As outlined at our recent Capital Markets event, this is where we are focusing our efforts. The continued improvement in the Group contributed per radiator measure clearly highlights the impact of proactive price and cost management, in addition to the benefits of strong product mix in the U.K. and Ireland. On slide nine, we can see how revenue is developed by operating segment.
Despite the 7.2% decline in sales volumes, U.K. and Ireland revenue only fell by 1.5%. In a trend similar to half one, sales in the segment benefit from an increase in the average size in terms of heat output for each radiator sold and a greater penetration of premium panel radiators. Strong sales of larger K3 and vertical radiators have continuing momentum, supported by building regulation changes.
We were also able to implement a U.K. price decrease in half two to recover inflationary cost rises. Within Europe, sales volumes declined by 0.6%, with business gains in Belgium, Netherlands, and Poland enabling a 4% year-on-year growth in half two. Despite improving volume performance, EUR revenue in GBP terms has been adversely impacted by 2.7% due to a year-on-year strengthening of the pound against the euro. Additionally, European revenues were negatively impacted by adverse country and customer mix and the impact of modest price concessions.
Sales in Turkey and China have both down in prior year, with ongoing weak economic activity in Turkey. On the following slide, we provide a bridge to the Group operating profits, giving an overview of the key movements before later looking at profit performance at a segmental level. The bridge clearly highlights the adverse impact of a 298,000 unit reduction in sales volume. More importantly, the bridge highlights the favorable impact that changing mix, proactive initiatives, and margin management have made to the Group's profitability. We believe that the improvements in the Group's profitability are now embedded in a stronger per radiator contribution, which leaves the Group well positioned for market recovery in the medium term. The next slide shows how changes to adjusted operating profit have impacted segmental profitability. In U.K. and Ireland, profit increased by £ 5.1 million, or 20.7%.
Whilst the segment continues to be adversely impacted by the most significant volume decline in the Group, it has benefited from an improving product mix, favorable selling and material prices, and the 2023 restructure. Operating profit in Europe has fallen by £ 1.2 million, or 12.4%, with improving volumes aiding second-half performance. The segment has benefited from the 2023 restructure and margin management. However, adverse country and customer mix, a small reduction in volumes, and inflationary cost increases have combined to more than offset these benefits.
The performance of Radiatori SPA within the Europe segment has been impacted by the weakness of the German and French markets in the year, with the latter in particular providing an attractive product mix. Margins for the Europe segment are expected to improve with market recovery. Turkey and international operating profit decreased by £0.3 million, with the segment impacted by a weak Turkish economy.
Central costs increased due to one-off consultancy costs related to the appraisal of premium panel strategies. Moving to the cash flow statement, we can see that both cash flow from operations and free cash flow are down compared to the prior year. EBITDA year-on-year improved by £ 2.3 million. However, this was offset by the cash unwind of provisions for one-off restructuring costs and investments in working capital. The significant working capital investment in the year within inventories has the Group invested to ensure it is able to continue to be well placed to respond to market demand and maintain best-in-class delivery performance. There was also a reduction in trade payables following a change in steel supplier in Italy. Despite the reduction in free cash flow, there has still been a reduction in net debt.
Leverage based on net debt before lease liabilities is 1.37 times EBITDA, which is a 0.1 times improvement on December 2023, with leverage benefiting from strong profitability growth. On this slide, we focus on other key financial areas. With taxation, as noted earlier, the effective tax rate has increased year-on-year to 29.4%, with the one-off credit in 2023 reducing the comparator charge. With dividends, as mentioned in the overview, we reiterate the final and therefore total dividend for 2024 will increase by 2%. Returning capital employed, led by strong adjusted operating profit performance, return on capital employed has decreased by 1.6 percentage points to 27.1%. The measure has also benefited from a reduction in the GBP value of euro assets due to the strengthening of the pound. Finally, we highlight that our two Group credit facilities, which total £ 100 million, remain in place until November 2026.
Our relationship with our banking partners remains strong, and at December 31, 2024, the Group has generous headroom on both facilities and available cash. Finally, my last slide provides technical guidance for use of analyst modeling. We expect the market environment to remain subdued for at least the first half of 2025. Key input prices are expected to remain stable during 2025. The Group will be making a one-off periodic investment in its IT infrastructure during 2025, which will give a modest increase in capital expenditure compared to 2024. During quarter four of 2024, the Group undertook a proactive price realignment exercise on its core range of contract products in the U.K., with equal reductions in both list prices and rebates. The price realignment is a commercial initiative designed at making the price points for our contract products more competitive and also at strengthening customer relationships.
During 2025, because of the reduction of rebates, there will be a consequential increase in working capital. Leverage based on net debt for lease liabilities is expected to fall during the year after a seasonal increase at the half-year. Finally, the Group tax rate is expected to exceed 30% due to a 5% increase in the withholding tax rate payable on dividends from Turkey. Thank you. Now I'll hand you back over to Trevor, who will provide the business review.
Thanks, Leigh. By way of a reminder, we are Europe's market-leading radiator manufacturer. According to the latest available 2023 market share data, we held the number one position in both the hydronic heat emitter market overall and the steel panel radiator market in particular, with shares of 11.8% and 20.2% respectively.
We serve over 500 customers across 40 countries, have a clear strategic focus on 10 core European markets, and operate five strong brands: Stelrad, Henrad, Hudevad, Termo Teknik, and DL Radiators. Stelrad operates in three geographic territories. The U.K. and Ireland represent 47% of total Group revenue. Europe represents 48%, while Turkey and international represents 5%. As we outlined at our couple markets event in November, the two key structural growth drivers of increasing premiumization and the drive for decarbonization will improve our product mix and margin and enable above-market growth. We have three competitive advantages that put us in prime position to take advantage of these market opportunities, namely the flexibility of our low-cost manufacturing facilities and processes, our leading levels of customer service and product availability, and finally, our market-leading competitive position.
Four clear, consistent strategic objectives continue to provide focus and direction: growing market share, improving product mix, optimizing routes to market, and positioning effectively for decarbonization. Taken together, the Group's market opportunity, structural growth drivers, and competitive advantages underpinned by a robust strategy translate into a set of ambitious medium-term targets which deliver clear stakeholder value: an increase in contribution per radiator, an operating margin of 13%, cash conversion of more than 90%, and a return on capital employed of over 30%. These medium-term targets exclude the benefits of an underlying market recovery for which Stelrad is very well positioned. To deliver on the structural growth drivers of increasing premiumization and the drive for decarbonization, we have a focused three-point strategy.
To capitalize on the opportunities presented by increasing premiumization in the U.K. market, we're leveraging Stelrad's traditional trade strengths with key initiatives to maximize the benefits of our brand positions, ensure that installers and merchant staff are supported in upselling to higher value products, and through installer-oriented marketing activities to remove any perceived barriers to recommending design radiators to homeowners. In 2025, we'll boost Stelrad's consumer appeal by the further development of our Stelrad.com e-commerce platform, supported by refocused investment in targeted consumer marketing. We continue to evaluate opportunities to develop channel partnerships for design radiators, where these are in the best long-term interests of the Group. In the drive for decarbonization, our strategic focus is on developing our product range and optimizing our routes to market.
As you will see later on, we have been successful in promoting high-output conventional radiators, which represent the most practical and cost-effective solution in lower temperature heating systems. We are continuing to extend our portfolio of multi-panel, multi-convector products. For heat pump systems operating at very low system temperatures, we are innovating to introduce new hybrid radiator ranges, which combine a traditional hydronic heat emitter with forced electrical convection to increase the heat output. In 2024, we launched one such product range into our German market in cooperation with a leading heat source and system provider, a long-established customer of Radiatori SPA. This low-temperature radiator has been well received by the market. Lastly, through the acquisition of Radiatori SPA, Stelrad gained access to a comprehensive portfolio of electric radiators, which were not previously commercialized outside of Italy, France, and Germany.
We're now able to leverage our leading market position, trusted brands, access to market channels, and long-standing specifier and customer relationships to introduce a focused electrical offer into our other core markets. The electric series in the U.K. market is a notable example, and from a standing start, we are now building a meaningful project pipeline. I'd now like to give you some concrete examples of our progress in 2024 towards improving product mix and positioning effectively for decarbonization. In terms of product mix improvement driven by increasing premiumization, Stelrad's premium steel panel mix represented 5.7% of the Group's volume in total. As a percentage of all steel panel volume, premium steel panel reached a record mix of 6.3% in 2024. This was an increase of 0.1 percentage points versus 2023.
Despite challenging macroeconomic conditions, it has now exceeded the levels seen during the post-COVID renovation peak in 2020 and 2021. Indeed, since 2015, our premium steel panel volume has grown at 3.4% per annum, while sales of standard steel panels have fallen by a CAGR of 2.6% over the same period. It's extremely pleasing to see the underlying underdeveloped U.K. market as the key driver of this improvement. U.K. premium steel panel mix rose from 2.9% in 2023 to 3.1% in 2024. As those of you who attended our couple markets event may remember, the U.K. market represents a significant opportunity for Stelrad. In eight of our 10 core markets, premium steel panel has between 5% and 26% penetration of the total steel panel radiator market. In comparison, the U.K. is underpenetrated in premium panel radiators, where Stelrad has sustainable competitive advantage and profitability levels are high.
Guided by our recent work with strategic consultants Eden McCallum, we continue to leverage our leading market position and number one brand to maximize this profitable opportunity through both traditional and emerging routes to market. We're making good progress in developing sales of higher heat output conventional radiators. Following changes to Part L of the U.K. building regulations, Stelrad has worked closely with specifiers and heating system designers, particularly in the new build sector, to find practical, cost-effective solutions capable of meeting the demands of lower temperature heating systems. As a result, in 2024, we saw significant growth in the U.K. sales of our higher value, higher heat output vertical K3 and 900 high radiators, volume increased by 66% over the prior year, which was in turn 34% higher than in 2022.
This contributed to a 6.4% overall increase in Stelrad U.K.'s average heat output per radiator sold relative to 2023 levels. We are also making good progress on ESG, driven by our strategic sustainability framework fit for the future. Our number one priority is to keep our employees and contractors safe, and we aim for zero harm across our operations. In 2024, our continued focus on safety standards resulted in us setting a new benchmark for lost-time incidents, with lost-time frequency rate falling by 45% to 4.75. Environmental product declarations, EPDs, provide transparent, verified information on the environmental impact of a product, and we are increasingly being requested by specifiers. This is particularly the case in Scandinavian markets, and in 2024, Stelrad published targeted EPDs for core ranges to ensure ongoing specifications in Denmark and Sweden.
will be publishing further EPDs during 2025, notably for our UK Green Series , which is manufactured with low carbon steel. Another credible achievement in 2024 was achieving UK certification for sending zero waste to landfill. We are also proud to support the United Nations Global Compact Initiative. In 2024, we committed to align our business with the 10 universally accepted principles in the areas of human rights, labor, environment, and anti-corruption, and to act in support of Sustainable Development Goals . Turning to the summary and outlook, Stelrad performed strongly in 2024, and the Group remains well positioned for sustainable profitable growth in the future. In challenging market conditions last year, we put in a robust performance, driving margin improvement through our total commitment to operational excellence.
For the seventh year running, we delivered an increase in our contribution per radiator, having set a new benchmark for premium steel panel radiator mix and having seen significant growth in our high-output conventional radiators in the U.K. market. Although we don't expect the current challenging market conditions to improve for at least the first half of 2025, Stelrad is very competitively positioned for 2025 and beyond. With three sustainable competitive advantages of flexible low-cost manufacturing, leading levels of product availability, and a position of scale as the European market leader in hydronic heat emitters, we believe that our considerable experience of successfully steering the business through other challenging market cycles will enable the Group to navigate the current conditions and deliver another year of progress. As we outlined at our November capital markets event, long-term trends for the Group are favorable.
We have an attractive market opportunity with positive underlying dynamics in the hydronic heat emitter market and a significant installed base ready for a replacement cycle that we expect to come through in the medium term. In premiumization and decarbonization, we have two structural drivers that will enable above-market growth through product mix and margin gains. Our resilient business model, clear, consistent, and robust strategy, and market leadership position underpin these opportunities and will enable Stelrad's proper growth over the coming years. With that, we will move over to questions.

The first question comes from a line of Aynsley Lammin from Investec. Please go ahead.
Hi. Morning, Trevor. Morning, Leigh. I think I've got morning. I've got two questions. Firstly, just obviously this year, I'd like to see much volume growth. Just wondering, when you look at the kind of price management and cost management, are you confident if we assume that volumes are flat across the group that you could at least hold the contribution per radiator? I guess a bit more color around pricing and cost. The second question, just in the U.K., if you could remind us again your exposure to new build and RM&I, and are you seeing any kind of pickup or better confidence among the new house builders and maybe a bit more color on the RM&I market as well? Thanks very much.
I'll take that, Leigh. Okay.
I think the first part of the question was about contribution per radiator, Ainsley, and you comment, do we see any further upside or are we confident of maintaining it? I think at this early stage, despite market uncertainty, I think we'll have a high degree of confidence that we can at least maintain the current contribution per radiator, the record level that we've achieved in 2024. We have set out some slightly more ambitious targets at the CME event for the medium term, and that was to exceed GBP 21 per radiator. In terms of the current market conditions, I would agree with you, Ainsley, that the commentary coming out of new build is certainly a little bit more positive than it has been for the last 18-24 months. However, Stelrad at this stage hasn't seen any benefit from that.
Of course, the heating system is one of the last elements installed into a new home. It will likely be probably five or six months before we see the benefits of any increased new build activity at the beginning of the year. Does that answer your question, Ainsley?
Yeah. Anything on the RM&I market? Any more color in the U.K.?
I mean, RM&I has been struggling somewhat because of poor consumer confidence. Although there are some early signs of some consumer confidence recovering, it is not significant enough to feed through into increased RM&I activity.
Just a reminder, Ainsley. In the U.K., new build is about 25% of our U.K. volume. The remainder is RM&I and commercial.
That's great. That's helpful. Thanks very much.
Thanks, Aynsley.
The next question comes from a line of Andrea Collins from Davy . Please go ahead.
Morning, Trevor. Morning, Leigh.
Congrats on the results this morning. I guess I have two questions, if that's okay. The first one is just in relation to the premium panel radiators. You mentioned the kind of further growth in the penetration rate in 2024. I guess I'm wondering, what are your expectations for this side of the business in 2025? I guess you kind of alluded to those key initiatives that you have in place now to assist premium panel growth in the U.K. When do you think we'll start to see an impact from these, or is it still too early to kind of see an impact there? My second question is on countries for radar, but I can come back to that if that's easier.
You're on to that, Leigh?
Yeah. I mean, in terms of the kind of premium panel mix, it's very different per geography.
In terms of the actual growth in that kind of mix this year at 5.7%, I guess depending on what happens where. For example, Germany, which is a market where we're struggling in recent years, the percentage of penetration there is around 20%. Where it goes in the immediate future depends on the wider economic recovery. As you alluded to, the significant challenge for us is growing that U.K. percentage. Whilst the growth was modest from 2.9% to 3.1% during 2024 for our largest market, that's a significant change in what we're looking to focus on. That feeds into the premium panel strategies, implementing that EMK strategic workstream.
I think in terms of timeline, there's obviously investment, not so much a cash investment, more of a process investment to ensure that the website, which is the first main lever, is fit for purpose in terms of pushing that kind of consumer sales. We're looking to get that aligned by the kind of quarter three, I think. In terms of back end of this year, we'd look to get some more traction on that moving into 2026.
Perfect. That makes sense. The second one is just on the contribution per radiator. I guess, could you give any more color on how this grew across the different product types? Standard versus premium versus design. Is there any kind of color on different geographies as well?
I think it's mainly by product type.
When you look at contribution per radiator across different geographies, it varies, but mainly because of the product mix. It is still that kind of what we always say that on average is about 20. If you're looking at a standard panel versus a premium, you're talking five times, six times a contribution. The kind of upscale benefit from moving from a standard to a premium is to get more or less five, six times contribution. It is similar kind of not as high, but kind of similar uptick on other products like column radiators and electric. There's that significant uptick in contribution per radiator.
Perfect. That's great. Thank you.
Thank you.
The next question comes from a line of Sam Cullen from Peel Hunt, please go ahead.
I've got three. I think they should be pretty brief, though.
The first one is, in terms of doing the strategy piece, you mentioned kind of support for installers and merchants. What kind of support do they need? Is it more training around the product, kind of more marketing materials to help with the upselling? Assume it's not kind of showrooms that they need, just interested to explore that. The second one is around slide 20 and the increase in higher output radiators. Can you give any commentary around what channel you're seeing that? Is it coming in the new build sector or the RMI sector? The last one, and I probably should know the answer to this, the hybrid and the electric ranges. You said you're designing them. Are you manufacturing those as well? If you're not, would you seek to?
I'll answer those freely. Thanks for the question, Sam.
I think the first one, in terms of merchant installer support, Leigh Wilcox Research highlighted the need to have some more focused marketing activity to reduce certain misconceptions about the complexity of installing premium and design products. We have instigated a training program and a targeted marketing campaign towards installers to get the message across in terms of how easy these products are to install and how cost-competitive they are. In terms of your question on slide 20, high-output conventional radiators, I mean, we recognize the growing popularity of low temperature systems driven primarily on the back of the building regulations changes of Part L. We have been very active with all sorts of specifiers, both across new build, social housing. We have seen those specifications come through in significant increased demand for those high-output products specifically targeted at low temperature heating systems.
Your last question was about the German initiative that Radiatori SPA had with one of their main customers for Germany. That is a product which I am pleased to report, Sam, is manufactured in-house.
Great. Thank you.
The next question comes from a line of Edward Prest. He is from Berenberg. Please go ahead.
Hello. Morning, Trevor. Morning, Leigh. I have got two, please. Firstly, in relation to sales channels, do you have any sense of how much stock is currently being held in merchanting and retail channels and how this is relative to a normal level? Secondly, back to contribution per radiator, obviously increasing for seven consecutive years.
As and when the U.K. recovers, given its relatively lower share of premium compared to other markets, is it reasonable to think a U.K. recovery might lead to a decrease in the contribution per radiator, or is it actually sort of in line with the broader group average? Thanks.
You want to answer those, Leigh?
Yeah. I mean, in terms of the U.K. stock channel, I've not had as much availability in the European stock channel. In the U.K., we get the information year on year, and there's been no significant change in terms of the level of stock in the channel. I think stock is critical to kind of the availability of radiators and the ability for that distribution to work. We have not seen any movement in that. In terms of contribution per radiator, yes, there is a kind of mixed element across the group.
In terms of if the U.K. was to recover significantly faster than Europe, there could be a change in contribution per radiator. That said, European economies have been equally suppressed in recent years. Furthermore, the development of the U.K. market would help to kind of push that premium trend in line with that development. We are optimistic on that basis that we would be able to sustain and not grow the contribution per radiator.
Okay. Brilliant. Thank you.
There are no further questions from the phone line. Handing over to Rosie to take questions from the webcast.
Thank you. We have one question from Charlie Campbell of Stifel. Can you explain the increase in inventories given the subdued outlook? Is there a mix shift here?
There is no mix shift to speak of. I think we have spoken about sustainable competitive advantages.
Product availability and customer service is key to that. What we've realized kind of in recent years is that the ability to supply our customers with the right product at the right time is just a significant advantage and one we're keen to take advantage of, just make sure we make the most of. That's the only kind of development there.
Thank you. Our next question is from James Wood at Canaccord. Is on time in full delivery of Europe a trackable KPI? If so, what are the trends for this region?
Answer that one. We've been tracking our on time in full for over 10 years. Interestingly, it was only last year during one of these events did we have an investor actually inquire about on time in full. He identified that it was a key measure that he was particularly interested in.
You will have noticed at the Capital Markets Event in November, we made a point of measuring on time in full for the U.K. marketplace. We made comment on on time in full for the U.K. in this particular presentation. It's a measure that is very important in the U.K. given the structure of the U.K. marketplace. We have seen merchants adjust their stock levels down slightly because the reliability of their supplies from Stelrad are so good. Yes, we have a long history of measuring on time in full, but it's only relevant for the U.K. marketplace, which is 47% of our revenues.
Thank you, Trevor. There appears to be no further questions on the webcast. That concludes today's presentation. Thank you, everyone, for joining.
