UK Heat Pump Market Hits Record Heights in 2025 — What That Means for Installers
New data released in early 2026 shows that the UK heat pump market continued its rapid growth trajectory in 2025, with installation demand reaching historic levels.
According to figures published by the Heat Pump Association UK, the market “reached another record high in 2025, with over 125,000 units sold in the UK, a 27% increase on the previous year.” This isn’t just incremental growth — it’s a powerful signal that heat pumps are firmly on the rise in the UK heating landscape.
Breaking down the headline figure further:
125,037 total heat pump sales, including 110,353 hydronic heat pumps in 2025.
A 27% increase in total sales compared to 2024.
Growth across all major segments:
Air-to-water monobloc heat pumps up 26% year-on-year.
Ground and water source heat pumps up 32%.
Domestic hot water heat pump sales up 36%.
The number of heat pumps manufactured in the UK jumped 38%, showing a strengthening domestic supply chain.
These figures emphasize not only growth, but diversification — with all major product types seeing strong increases. Yet the report also reminds us that even this record performance falls short of the wider policy goals: to meet the Warm Homes Plan aim of 450,000 heat pump installations annually by 2030, sales would need to grow at a 33% compound rate year after year.
Industry Voices: Confidence and Caution
Charlotte Lee, Chief Executive of the HPA UK, offered a measured perspective on the results:
“Following the publication of the Warm Homes Plan, it’s evident that heat pumps remain a pivotal technology to decarbonise heat in the UK. The continued growth of the UK heat pump market is extremely positive, but to meet the government’s target of 450,000 heat pump installations annually by 2030, momentum must be maintained.”
Lee’s remarks reflect both the bullish growth trend and the challenge ahead: maintaining, and even accelerating, the pace of adoption to meet broader climate and energy goals.
Why Heat Pump Training & Support Matters More Than Ever
All the data points above underline one clear reality - the heat pump industry is booming. But a booming market is only as strong as the skilled professionals who install and maintain these systems.
The growth in heat pump sales and installations creates massive demand for qualified installers, a challenge that the industry has been grappling with as traditional gas-boiler skillsets transition into low-carbon technologies.
This is where quality training and installer support become mission-critical.
How Alto Energy Are Leading the Way in Upskilling and Support
At Alto Energy, we are helping independent heating engineers and solar tradespeople break into the heat pump market.
FREE Heat Pump Training Courses
We offer a completely free heat pump training course designed specifically for experienced plumbers and heating engineers who want to move into heat pump installations without needing to become MCS-accredited themselves.
Here’s what the training delivers:
Fundamental and practical heat pump installation skills, covering both air source and ground source systems, including brands like Mitsubishi, Samsung, Worcester Bosch and Viessmann.
Instruction on mechanical and electrical installation, system design, component siting and operation — tailored to the real needs of tradespeople moving into renewables.
A half-day course format, making it accessible even for busy field engineers.
The goal? To give installers confidence and hands-on insight so they can start fitting heat pumps sooner rather than later — a crucial advantage given the rising market demand.
Heat Pump Umbrella scheme — Taking the Technical Burden Off Installers
One of the biggest barriers for installers breaking into heat pumps is the complexity and cost of attaining MCS accreditation — the recognised certification scheme required for many government-backed incentives.
Our MCS Umbrella Scheme simplifies that journey, giving engineers and tradespeople a clear route into the sector.
Under our umbrella scheme:
Alto Energy handles design, supply, commissioning, compliance and certification on behalf of the installer.
Installers can work under Alto’s MCS accreditation, unlocking access to government incentives such as the Boiler Upgrade Scheme.
Technical backup, compliance management and customer support are included — meaning installers can focus on what they do best: installs.
No wonder many independent engineers are turning to schemes like this to bridge skill gaps without having to navigate the administrative weight of certification alone.
In Summary: A Market on the Move — And a Workforce Ready to Step Up
The record heat pump sales figures from 2025 — 125,037 units and a 27% annual increase — point to a market that’s gaining real traction.
But strong demand brings clear requirements:
A bigger, better-trained installer workforce
Accessible education and upskilling pathways
Support systems that take the burden off small businesses
By providing free training and industry-leading MCS umbrella services, we are making it easier for heating engineers and solar professionals to expand their skills and take advantage of the opportunities in the heat pump market.
For independent installers looking to stay ahead of the curve, this combination of market insight and practical support could be the key to capturing a share of the heat pump revolution.
