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. This change would reflect an anticipated fall in measure installation activity from March 2026 data onwards, the original end date of the ECO4 scheme. Because the ECO statistical release reports ECO measure installations two months in arrears, figures up to the end of March 2026 were published in the May 2026 publication. 

Although the period for ECO4 delivery has been extended to end 2026 to allow suppliers further time to meet targets and carry out remediation work, we expect low installation activity. We therefore propose ceasing with monthly updates and having two further publications: one publication in six months (i.e. at the end of 2026) and one publication with final figures up to the end of the scheme (including any final data revisions) in summer 2027. 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.

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.
