Policy areas

The Energy Company Obligation (ECO) is a government energy efficiency scheme for Great Britain, administered by Ofgem. Our guidance documents provide information on the legislative requirements of the draft ECO3 Order and our administrative processes. Pending the commencement of the ECO3 Order powers in the autumn, measures that meet the scheme rules can be delivered from the 1 October 2018. 

We have published the Supplier Administration guidance document as a draft for comment basis to assist suppliers with early delivery before the commencement of the ECO3 Order. It is our intention that stakeholders may apply these policies and use the documents from 1 October onwards. However, as noted above, the ECO3 Order is still in draft form, and as such, any delivery is at stakeholders’ own risk.  

Stakeholders should provide any feedback on this draft copy by email to by 14 November 2018 so that we can publish this in a final version as soon as possible.

We would like to seek feedback on the following questions:

  1. the overall tone of the guidance, is the draft guidance easy to read and understand? Are there any sections which could have been better explained?
  2. is the draft guidance user friendly?
  3. are there any sections of the draft guidance which are ambiguous?
  4. was enough detail provided in the draft guidance document around our approach to the administration of ECO3? If not, where is more detail needed, and why?

We have split the ECO3 Guidance into two parts.

  1. ECO3 Guidance: Supplier Administration, and
  2. ECO3 Guidance: Delivery.

The Supplier Administration guidance is aimed mainly at suppliers, describing the processes that suppliers and Ofgem follow to meet the requirements of the ECO3 Order. It addresses the following:

  • when a supplier is obligated under ECO3 and how its obligations are set
  • details of the solid wall minimum requirement
  • details of the rural sub-obligation
  • how suppliers notify completed ECO measures
  • carry-over and early delivery of measures
  • the application process for trading obligations
  • the application process for transfers and re-elections, and
  • our role as the ECO administrator

For measures installed before 30 September 2018, please refer to our ECO2t guidance Delivery and Administration, Versions 1.1.
