Policy areas

The Energy Company Obligation 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. Measures that meet the scheme rules can be delivered from 1 October 2018.

We have published the Delivery guidance document on a draft for comment basis to assist suppliers with early delivery before commencement on 3 December 2018. 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 29 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 the overall tone of the guidance, is the draft guidance easy to read and understand?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 is the draft guidance user friendly?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 are there any sections of the draft guidance which are ambiguous?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 was enough detail provided in the draft guidance document around our approach to the administration of ECO? 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 Delivery guidance is aimed at suppliers and the broader supply chain, describing how to deliver measures that are eligible to contribute towards the ECO targets. The Delivery guidance addresses the following:

  • how a supplier achieves its obligations
  • which measures are eligible under ECO and the criteria that must be met
  • specific requirements relating to eligibility
  • how to determine ECO savings, including information on deemed scores and SAP/RdSAP
  • how measures are notified and the information we require
  • the technical and score monitoring requirements that suppliers must meet
  • the auditing and counter fraud processes that suppliers will be subject to.

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