Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what estimate he has made of the number of homes unable to take heat pumps because of (a) technical reasons and (b) affordability.

Analysis conducted by Government suggests it would be technically feasible to install a heat pump in around 90% of British homes, based on analysis of homes’ current energy efficiency and internal electrical limit. Practical considerations, like space availability or compliance with planning regulations, may limit where heat pumps can be installed, but we are supporting innovation to develop solutions to these challenges.

The Government is investing £6.6 billion over this Parliament towards clean heat and improving energy efficiency in buildings, including the Boiler Upgrade Scheme, Home Upgrade Grant and Social Housing Decarbonisation Fund, which support the installation of heat pumps.
