Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what estimate she has made of how many households have (a) applied to and (b) had insulation installed through the Great British Insulation Scheme.

Through the GOV.UK self-referral service, there have been over 76,000 referrals for the Great British Insulation Scheme (GBIS) up to 7 January 2024. The Department does not hold data on how many customers have applied for the scheme through other routes.

Information on the number of insulation measures installed through GBIS can be found in the latest GBIS Statistical Release.
