Heat pump sales hit record 125,000 but growth slows

UK – Data from 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. Although the figures represent a 27% increase on the previous year, the rate of growth was down from the 56% jump experienced in 2024.

The association has called for urgent action to unlock further growth and points out that in order to achieve the 450,000 installations per year by 2030 target set out in the Government’s Warm Homes Plan, the UK would need to see 33% compound growth of in sales year on year.

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.”

The UK factory gate sales data includes air-to-water monobloc and split units, ground and water source heat pumps, domestic hot water heat pumps and “other” such as exhaust air and Integrated hybrid heat pumps. It does not include air-to-air heat pumps. Key highlights include:

• 125,037 total sales including 110,353 hydronic heat pump sales
• 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

Paul Kenny, Director General of the European Heat Pump Association, added:  “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.“
