This publication contains the ECO3 Deemed Scores Matrix, which can be used for measures delivered from 1 October 2018.
The deemed scores presented in this document are ‘lifetime scores’, and relate to the average treatable area for the measure type. Additional versions of scores are included which incorporate any applicable uplifts. In some cases, the percentage of the measure installed and percentage of property treated must also be determined to ensure the correct score is notified.
Full guidance on the use of deemed scores is given in Chapter 6 of the ECO3 Guidance: Delivery document.
This page also includes any deemed scores which have been applied for by suppliers and approved by Ofgem. Once published on this page, any supplier can claim the scores for the appropriate measures, assuming all the relevant criteria are met.
Further information on the development of the deemed scores is published on our ECO3 deemed scores consultation decision page.
If you have a query about the deemed scores or their use, you can contact us at email@example.com.
ECO3 Deemed Scores Matrix - version information
Version 1.1 was published on 30 November 2018. Changes from the previous version are the removal of scores for the measure type “B_broken” relating to the following pre main heat sources:
- electric room heaters
- electric storage heaters
- gas room heaters
- solid fossil fuel room heaters
B_broken scores for these heat sources were developed prior to the ECO3 legislation being finalised. Whilst they were in line with our understanding of policy intentions at the time, they cannot be used under the legislation as passed. These heat sources can still be replaced as first time heating measures.
Version 1.0 was published on 23 July 2018 alongside the ECO3 deemed scores consultation decision.
