Introduction
The Great British Insulation Scheme (GBIS) is a government scheme to help people insulate their homes, make them more energy efficient and save money on their energy bills.
The government announced the scheme at the end of March 2023. The £1 billion scheme will help around 300,000 households across the country with the cost of installing new home insulation. The scheme is scheduled to run until March 2026.
What you need to know about these statistics
The data contained in the analysis is based on preliminary data provided by TrustMark, covering installations of measures between May and October 2023. The data are based on the handover date for completed measures as recorded in the TrustMark Data Warehouse.
Once measures are lodged with TrustMark they are notified to Ofgem who carry out verification checks. As these data have not been subject to checks by Ofgem the data are subject to revision.
Please note, these data are Official Statistics in development as they use data from the TrustMark Data Warehouse. They are to be used as an indication of measures installed under GBIS so far. These figures will be revised in future publications once data on measures installed from Ofgem is available.
