Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, whether he has made an assessment of the potential role of heat batteries in decarbonising domestic heating.

Through our Warm Homes Plan we are focused on rolling out home upgrades across the country, with a focus on heat pump installation and fabric solutions.

In many cases heat batteries are less efficient than heat pumps, however they do not require outside space, and can often be cheaper to install in some circumstances.

We are currently exploring the role heat batteries could play in the future.
