Heat Pumps: Grants
The question
To ask the Secretary of State for Energy Security and Net Zero, how much grant assistance has been paid from the public purse for heating pumps since July 2024.
Answered by Martin McCluskey
Between July 2024 – March 2026, the Boiler Upgrade Scheme paid out 51,444 vouchers for heat pumps, to the cost of ~£386 million.
Other schemes delivered by the department, such as the Home Upgrade Grant (HUG), Social Housing Decarbonisation Fund (SHDF), Warm Homes: Social Housing Fund and Local Grant (WH:SHF ; WH:LG) do not provide a breakdown of spend specific to heat pump subsidies alone, as they support a broader range of retrofit energy efficiency measures. However, the Government does publish data showing the average contribution costs for individual measures under these schemes, including for heat pumps.
