Warm Homes Plan: Batteries

The question

To ask the Secretary of State for Energy Security and Net Zero, what assessment he has made of the value of stand-alone batteries in the Warm Homes: Local Grant scheme for homes where solar PV is not present and may not be suitable.

Answered by Martin McCluskey

Domestic batteries are an eligible measure under the Warm Homes: Local Grant. Batteries can only be installed where they complement existing or new solar PV. This is to ensure that households realise the full benefits of installing a battery.

Measure eligibility policy for the Grant is kept under review.

All measures installed under Government schemes must adhere to the latest PAS 2035:2023 guidance and installers must be Trustmark registered and PAS 2030:2023 certified for energy performance measures and MCS certified for low carbon heating measures such as batteries.
