The number of heat pump sales reached record highs last year, according to new data from the Heat Pump Association.
It revealed 125,037 units were sold across Britain last year. That’s an increase of 27 per cent on the 98,345 installed in 2024 and almost double the number installed in 2023.
The majority of heat pumps being installed are air-to-water (A2W) monobloc heat pumps, typically referred to as air source heat pumps.
However, there was also a rise in domestic hot water heat pumps, going from 10,772 in 2024 to 14,684 sales last year.
These only provide hot water within a single home – giving owners control over their hot water system instead of sharing a heat network.
Ground source heat pumps also saw an uptick in sales going from 3,087 in 2024 to 4,070 last year.
UK heat pump sales reached record highs in 2025, with more than 125,000 units sold, according to the Heat Pump Association (HPA)
The increase in sales has likely been propelled by massive financial incentives being offered by the Government to developers and homeowners.
In England and Wales there are grants up to £7,500 under the so-called Boiler Upgrade Scheme (BUS) to install a heat pump.
The typical cost of installing an air source heat pump is around £11,000, according to the Energy Saving Trust.
However, the price can vary depending on the brand, the size of the heat pump, the size of your property and whether radiators or the hot water cylinder need to be added or upgraded.
Heat pumps are marketed as an energy efficient way to heat homes with potential savings when it comes to energy bills.
However, there have been reports of heat pumps proving unreliable, resulting in soaring electricity bills and cold homes.
Sue Davies, of consumer group Which?, says more needs to be done to ensure homeowners do not receive bad advice or botched installations.
She says: ‘Although we are seeing progress, our research shows high upfront costs and a lack of consumer confidence in these technologies remain some of the biggest barriers for households.
‘In order to continue to support the transition to heat pumps and solar panels, the government needs to make sure the upfront costs of these technologies are more affordable and that people have access to good quality independent advice and reliable installers.
‘The Government must also prioritise a concrete plan for strengthening consumer protection – this was a concerning omission in the Warm Homes Plan given the dismal track record of certain government-backed heating schemes such as ECO4.’
