The UK remains one of Europe’s biggest boiler markets, but the industry is changing rapidly. Most British homes are still heated by a gas boiler and wet‑based central‑heating system, yet a combination of net‑zero policies, rising fuel prices and alternative technologies such as heat pumps is starting to reshape the market. This article brings together the latest official data and credible industry reports (updated to mid‑2025) to help homeowners and professionals understand how boilers are used in Britain today, what they cost and where the market is heading. How many boilers are in use? Gas grid dominance – The Committee on Climate Change (CCC) estimates that about 85 % of UK homes – roughly 23 million properties – are connected to the gas grid and use a boiler and wet‑based central‑heating system theccc.org.uk. Around 4 million homes lie off the grid and use oil, LPG or electric heating theccc.org.uk.   Homes heated with boilers – A recent industry review from GreenMatch notes that around 90 % of UK homes still rely on a boiler system for heating and hot water greenmatch.co.uk, emphasising the continued dominance of boilers despite strong policy support for heat pumps.   Dominant boiler type – Combination (combi) boilers are by far the most popular design; they deliver hot water on demand and remove the need for separate cylinders or tanks. The Heating and Hot Water Industry Council (HHIC) reported that more than 80 % of domestic boilers sold in 2021 were combi models hhic.org.uk. GreenMatch quotes similar figures and notes that combi boilers account for roughly 80 % of all domestic boiler sales greenmatch.co.uk.   Number of boilers sold – The post‑pandemic bounce in home renovation drove a surge in boiler sales. HHIC reported that from January–April 2021 there were 674,063 domestic gas boilers sold compared with 476,847 over the same period in 2020 – a 41 % increase hhic.org.uk. Sales fell back in 2023; the European Heating Industry (EHI) Heating Market Report 2024 recorded 1,359,300 gas condensing boilers sold in the UK in 2023, contributing to over 1.5 million heating units sold in that year ehi.eu. GreenMatch cites Statista data suggesting that about 1.8 million domestic boilers were sold in 2022 greenmatch.co.uk, illustrating how 2022 was a high‑water mark.   Gas‑safe workforce – HHIC estimates that around 130,000 Gas Safe registered installers operate in the UK hhic.org.uk. The CITB Construction Skills Network forecasts only a small change in trades numbers between 2022 and 2027 (plumbing & HVAC trades: 118,600 → 118,800; electrical trades: 198,300 → 202,600) citb.co.uk, highlighting the challenge of training enough engineers for the heat‑pump transition.   Boiler efficiency, emissions and regulation Energy use and bills – Heating and hot water account for over half of an average household’s annual energy bill, so the efficiency of a boiler has a big impact energysavingtrust.org.uk. Modern condensing boilers capture more heat from flue gases and are more efficient than older models energysavingtrust.org.uk.   Carbon footprint – Domestic heating makes up roughly 14 % of UK greenhouse‑gas emissions nesta.org.uk. Fossil‑fuel boilers are the main source; the Ofgem Boiler Upgrade Scheme (BUS) report notes that more than 78 % of homes in England and Wales are heated by fossil‑fuel systems ofgem.gov.uk.   Minimum efficiency standards – From 2025, all newly installed boilers in the UK must have a Seasonal Efficiency (ErP) rating of at least 92 % greenmatch.co.uk. Building Regulations Part L already require modern boilers to be condensing types, and hydrogen‑ready boilers are being trialled with a view to wider rollout from 2030 greenmatch.co.uk.   Heat‑pump transition and grants – The UK government aims to phase out fossil‑fuel heating in new homes by 2025 and reach 600,000 heat‑pump installations per year by 2028. The BUS provides grants up to £7,500 for air‑source and ground‑source heat‑pump installations. The 2023‑24 BUS annual report shows that by March 2024, nearly 24,000 applicants had received support and that 47.2 % of grants replaced gas boilers while 20.1 % replaced oil boilers ofgem.gov.uk.   How much does a new boiler cost? Boiler costs vary according to type, size and installation complexity. Specialist suppliers such as Heatable and independent consumer guides provide the following ranges: Typical installation cost range – Heatable’s 2025 price guide says a typical new boiler installation costs between £1,500 and £5,500 depending on the type and complexity heatable.co.uk. Their quick summary estimates £2,500–£3,500 as a common range for a straightforward installation heatable.co.uk.   Detailed breakdown by type – The Eco Experts’ 2025 guide places the average cost of installing a new boiler at about £4,000, but notes that prices vary from £3,800 for a gas combi boiler to £16,000 for a biomass boiler theecoexperts.co.uk. For a typical three‑bedroom house (costs include installation):   Gas combi boiler – £3,800 theecoexperts.co.uk.   Gas system boiler – around £4,000theecoexperts.co.uk.   Gas conventional (heat‑only) – roughly £4,200 theecoexperts.co.uk.   Electric combi boiler – about £3,350 theecoexperts.co.uk.   Oil boiler – approximately £4,700 theecoexperts.co.uk.   Biomass boiler – around £16,000 theecoexperts.co.uk.   The same guide notes that a new boiler costs between £2,200 and £5,000 depending on property size; costs rise in larger homes theecoexperts.co.uk.   Running costs – Although not directly measured here, switching from an old G‑rated boiler to a new A‑rated condensing boiler can save around £385 per year in energy costs according to Heatable’s estimates heatable.co.uk.   Boiler reliability and breakdown statistics Breakdown frequency – Research by boiler‑service firm Fair Fix analysed breakdown data between 2009 and 2019 and found that 5.1 % of boilers failed each decade, equating to about 107,108 breakdowns per year londonlovesproperty.com. England has around 20.8 million households reliant on boilers londonlovesproperty.com.   Financial impact – With the average repair costing about £300 per boiler, Fair Fix calculates that boiler failures cost households roughly £32.1 million per year londonlovesproperty.com. London has the highest failure rate at 6.1 % (about 18,661 breakdowns a decade), followed closely by the West Midlands (6 %) and the North East (5.6 %) londonlovesproperty.com. Fair Fix notes that modern boilers are

(Source: Electrical Safety First)   Employment and skills shortage Workforce size – The Construction Industry Training Board (CITB) reports that the UK had about 118,600 plumbing and HVAC tradespeople and 198,300 electrical trades and installation workers in 2022. Employment is expected to remain stable, with 118,800 plumbers/HVAC technicians and 202,600 electricians forecast by 2027  citb.co.uk. Despite weak construction output, the sector faces high demand for workers: the CITB estimates that the construction industry needs to recruit nearly 45,000 extra workers every year to meet projected workload  citb.co.uk. Skills gaps and apprenticeships – A growing skills gap threatens both trades. The MyJobQuote 2025 salary guide notes that the UK Trade Skills Index forecasts an additional 104,000 electricians will be needed by 2032. Only about 10 % of learners in government‑funded electrical courses progress to apprenticeships, and the Electrical Contractors’ Association (ECA) warns that recruitment must reach 5 % of the existing workforce each year (currently under 4 %) to avoid shortages smart-energy.com. Plumber training is also under pressure; a shortage of qualified tradespeople contributes to rising wages. Earnings and gender pay disparities Typical salaries – According to the National Careers Service, plumbers in the UK earn roughly £24,000 as a starter and up to £46,000 when experienced nationalcareers.service.gov.uk. Electricians earn a similar range – £26,000 for new entrants rising to about £45,000 for experienced workers nationalcareers.service.gov.uk. Self‑employed tradespeople can earn more; MyJobQuote estimates that experienced electricians can command ~£25 per hour (£52,000 per year) and self‑employed electrician business owners earn around £65,000. Pay growth – Trade‑press monitoring from PHAM News shows that self‑employed plumbers’ weekly earnings reached £1,142 in January 2025, an 11 % year‑on‑year increase. Earnings dipped 3.8 % month‑to‑month but remained high because of sustained demand and the limited supply of skilled plumbers phamnews.co.uk. Gender pay gap – A pay‑gap study cited by PHAM News found that male plumbers earn about £25.88 per hour while female plumbers earn £18.10 per hour. Electricians have a similar gap: male electricians earn £26.51 per hour versus £18.54 for females, leaving women tradespeople earning about £16,000 less per year phamnews.co.uk. The figures highlight the under‑representation and undervaluation of women in trades. Heat pumps and decarbonisation Government targets – The UK Government’s Ten‑Point Plan aims to install 600,000 heat pumps per year by 2028 gov.uk. This ambition is huge: a National Audit Office (NAO) report noted that just 55,000 heat pumps were sold in 2022, so reaching the target requires an eleven‑fold increase nao.org.uk. Recent sales boom – Industry data from the Heat Pump Association (HPA) and Renewable Energy Installer shows that hydronic heat‑pump sales grew 63 % in 2024, with about 98,469 hydronic units sold, and 60 % of those sales were notified to the Microgeneration Certification Scheme (MCS)  heatpumps.org.uk renewableenergyinstaller.co.uk. Around 9,062 individuals completed heat‑pump training courses in 2024, a 15 % increase on 2023 heatpumps.org.uk. Another Renewable Energy Installer article noted that there were 40,426 certified heat‑pump installations in 2023 and more than 42,000 by September 2024, bringing total cumulative installations to nearly 260,000 renewableenergyinstaller.co.uk. Despite rapid growth, the industry remains far from the 600,000‑per‑year goal, underlining the need for more installers and consumer incentives. Energy consumption and
