Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, if his Department will launch a consultation on including heat batteries as part of the Boiler Upgrade Scheme.

Heat batteries are one of the most promising alternative electric heating technologies, however, they are less efficient than heat pumps and will therefore use more energy to meet the same heating demand.

We expect most properties will ultimately switch to heat pumps as these are a proven technology and have been installed in high numbers in other countries. The Boiler Upgrade Scheme has also been designed to direct support towards technologies that offer the greatest carbon savings.

The Government will keep its position on alternative electric heating technologies under review as the supporting evidence base develops.
