Heat pump sales in the UK reached a new record in 2025, with more than 125,000 units sold, marking a 27% increase on the previous year, according to data from the Heat Pump Association UK (HPA UK).

The figures show that 36% of the heat pumps sold were manufactured in the UK, reflecting a 38% rise in domestic production compared with 2024.

All major types of heat pumps saw growth. Sales of air-to-water monobloc systems increased by 26%, while ground and water source models rose by 32%, and domestic hot water heat pumps grew by 36%. Hydronic heat pumps accounted for 110,353 of the total units sold.

Despite the increase, the pace of growth has slowed compared with the 56% surge recorded in 2024. Analysts say the market would need to sustain annual growth of around 33% to meet the Government’s target of 450,000 heat pump installations per year by 2030, as outlined in the Warm Homes Plan.

The HPA UK highlighted the economic potential of accelerated heat pump adoption, estimating that expanding the deployment of hydronic systems in line with the Carbon Budget Growth and Delivery Plan could boost UK gross value added by £14 billion over the next decade and cut reliance on imported gas by up to 62% by 2035.

Charlotte Lee, chief executive of HPA UK, says continued growth is “extremely positive” but stresses that government action is needed to maintain momentum:

“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, comments that UK sales growth reflects “steady policy support from the government in recent years” and could serve as a model for EU markets. He adds:

“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.”
