New data published by the Heat Pump Association UK shows that heat pump sales reached another record high in 2025, with over 125,000 units sold in the UK, a 27% increase on the previous year.
This marks another year of sustained growth for the sector, with 36% of heat pump sales being manufactured in the UK.
Breaking down the HPA UK factory gate sales data further, key highlights include:
- 125,037 total heat pump sales, including 110,353 hydronic heat pump sales in 2025
- A 27% increase compared to 2024 sales
- All types of heat pumps saw a steady increase in sales when comparing 2025 to 2024, with a 26% rise in Air to Water Monobloc heat pumps, a 32% increase in Ground and Water source heat pumps and 36% increase in Domestic Hot Water heat pump sales
- The number of heat pumps sold in the UK that were manufactured in the UK increased by 38% in 2025 relative to 2024
Whilst this growth is very positive, the rate of growth has slowed compared to the 56% surge recorded in 2024. To achieve 450,000 heat pumps installed per year by 2030, in line with the target set out in the Warm Homes Plan, the market would need to see 33% compound growth in heat pump sales year on year.
The latest analysis shows that the economic opportunity associated with accelerating the deployment of hydronic heat pumps in line with the Carbon Budget Growth and Delivery Plan could increase UK gross value added by £14 billion over the course of the decade and contribute to a potential 62% reduction in the reliance on imported gas by 2035.
Commenting on the data, Charlotte Lee, HPA UK, Chief Executive, said: “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.
“The sector eagerly awaits the publication of the Future Homes and Building Standard Regulations and calls on the Government to urgently publish a consultation which sets out options to reduce the price of electricity relative to gas. Both are needed to provide the sector with confidence that the main barriers to accelerate heat pump deployment are being unlocked.”
Paul Kenny, Director General of the European Heat Pump Association, commented: “The growth in UK heat pump sales is testament to the steady policy support from the government in recent years, a link that also clearly plays out across EU markets.
“This positive trend will be consolidated by the UK’s new Warm Homes Plan. Its comprehensive mixed package of regulatory actions and long term funding of subsidies can serve as inspiration to EU markets looking to grow their heat pump sectors and reap the benefits in terms of competitiveness and domestic production.
“However, as in much of Europe, the ratio of tax on electricity to gas remains an issue in the UK and must be addressed to ensure heat pumps large and small are the most cost efficient choice for end users.“
With the Warm Homes Plan reaffirming the Government’s commitment to heat pumps, HPA UK are calling for urgent action to unlock further growth.
