Household Energy Efficiency Statistics
This series brings together statistical releases relating to the Energy Company Obligation (ECO), Green Deal, and insulation levels.
Proposed change to ECO statistics release schedule – user feedback requested
We propose moving ECO measures statistics from a monthly publication to a less frequent publication, for example quarterly. This change would reflect an anticipated fall in measure installation activity from March 2026 data onwards, the original end date of the ECO4 scheme prior to the extension announced in January 2026. Because the ECO statistical release reports ECO measure installations two months in arrears, figures up to the end of March 2026 will be published in the May 2026 publication.
We welcome feedback from users on this proposed change, including any concerns or specific data requirements.

This series presents statistics on the Energy Company Obligation (ECO) and Green Deal (GD). It incorporates changes as set out in response to the user consultation of National Statistics on the Green Deal, Energy Company Obligation and Insulation statistics. The headline releases present monthly updates of ECO measures and quarterly updates of in-depth ECO statistics, carbon savings and the Green Deal schemes. The detailed report presents annual updates on in-depth ECO statistics and insulation levels.
Historical releases are available on request, see contact details below.
