Revisions to measure delivery

Please note that the Ofgem data featured in the June 2026 release continues to be provisional and subject to revision pending ongoing processing and validation of measures by Ofgem. The below proposal is that one more publication will be produced in autumn 2026 to cover any final revisions.

Proposed change to GBIS statistics release schedule – user feedback requested 

As the GBIS statistical release reports GBIS measure installations two months in arrears, final figures up to the end of the scheme were published in the May 2026 publication. 

Therefore, we propose ceasing the monthly updates and have just one further publication in autumn 2026 to account for any final data revisions. Future publication dates will be published on gov.uk in advance. 

We welcome feedback from users on this proposed change, including any concerns or specific data requirements we should consider.

Monthly release of data on the Great British Insulation Scheme. The tables provide analysis on the measures installed and households receiving measures. The statistics provide analysis by measure type and geography. Within each publication, a commentary explaining the key trends is provided. This scheme covers Great Britain.

The statistics cover the scheme from the launch at the end of March 2023. The data included are two months in arrears.

These statistics are provisional and are subject to future revisions.
