Great British Insulation Scheme
The Great British Insulation Scheme scores matrix sets out the scores energy companies will receive for measures they install under the scheme. The matrix can be found at the bottom of this page.
Full information on how scores work can be found in chapter 6 of the Draft Great British Insulation Scheme Delivery Guidance.
The Great British Insulation Scheme adopts the ECO4 partial project scores framework. The Great British Insulation Scheme scores matrix is therefore the same as the ECO4 partial project score matrix, except that measure types ineligible for the scheme have been removed.
If you have a query about the scores or their use, you can contact us at ECO@ofgem.gov.uk.
