Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what estimate her Department has made of the number of homes that will receive insulation through a scheme funded from the public purse in the next (a) five and (b) 10 years.

Around half of homes in England have reached our aspiration of having an Energy Performance Certificate with a rating of C – up from just 14% in 2010.

Government schemes have delivered insulation and other energy efficiency measures to over 400,000 homes over the past 3 years. In addition to this, our recent announcement of an additional £6bn support from 2025-2028 will support the installation of insulation and other energy efficient measures for another half a million homes.

Schemes beyond 2028 are still to be determined.
