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 firstname.lastname@example.org.
ECO3 Deemed Scores Matrix - version information
The current version is 1.3, and was published on 7 June 2019. The only change is the addition of scores relating to smart thermostats. Information on the use of these scores can be found in Chapter 6 of the ECO3 Guidance: Delivery document.
Version 1.2.1 and was published on 8 March 2019. Changes between v1.1 and v1.2 were:
- The addition of a new measure type, CWI_partial_fill
- The addition of new variants of non-insulation measure types incorporating the uplift “LA_F&G_nonPRS”
- The addition of new variants of insulation measure types combining the heat source “Gas boiler*” and the uplift “nonmainsgas_insulation”
CWI measures installed to cavities with partial fill insulation where the measure is completed and handed over from 1 April 2019 onwards, must be notified using the CWI_partial_fill measure type. CWI measures installed to empty cavities should continue to be notified using the standard CWI measure types.
Version 1.2.1 was published on 8 March 2019 with the same changes as above, but was replaced, as two measure names (RIRI_res_in and RIRI_res_unin) contained errors.
Version 1.1 was published on 30 November 2018. Changes from the previous version were the removal of scores for the measure type “B_broken” relating to non-boiler heat sources. These heat sources should be replaced as first time heating measures.
Version 1.0 was published on 23 July 2018 alongside the ECO3 deemed scores consultation decision.
