ECO public reports and data

The table below provides an overview on volumes of both projects and measures submitted under ECO4.

ECO4 commenced on 27 July 2022 and will run to 31 March 2026. Measures delivered between 01 April 2022 to 26 July 2022 will contribute to ECO4 delivery and will be known as ECO3 Interim measures as they are delivered in accordance with ECO3 regulations. Suppliers had to notify us of any ECO3 Interim measures installed between 01 April 2022 and 26 July 2022 by the end of September 2022. Any ECO4 measures completed between 27 July 2022 and 31 July 2022 also had to be notified by the end of September 2022. Any measures completed on or after 01 August 2022 must be notified by the end of the month following the month in which installation of a measure was completed.

We update the information in this table on a monthly basis and have included a breakdown of notified measures by category.

Notes:

  • ECO4 register functionality is undergoing development. We aim to provide a view on projects and supplier compliance progress against their ECO4 obligations in the coming months.

Table commentary:

The table above shows the measures submitted to Ofgem as of 09 May 2023.

A total of 22,748 ECO4 projects have been submitted, increasing by 3,785 projects from the previous month.

* 'First time central heating to an unknown heating system' has been added to the measure table as a small number of measures have been submitted with an invalid post main heating source for the property.

** ‘TBC’ has been added to the Measure Category table due to a small number of measures being submitted with an invalid measure name. We have engaged with the relevant suppliers to resolve these and will update in due course.
