This publication is for ECO1 reference only and applies to measures installed on or before 31 March 2015. For measures installed under ECO2 (1 April 2015 - 31 March 2017) please refer to the ECO2 Guidance.
This page explains how we let energy suppliers know if we have refused or revoked approval of an energy efficiency measure under the Energy Companies Obligation (ECO1).
After a supplier notifies a measure to Ofgem we must decide whether we can attribute savings to the measure. We may decide that we can and in this case we say we have ‘approved’ the measure. We may decide that we cannot and in this case we say we have ‘refused to approve’ the measure.
Sometimes we need to revoke an earlier decision to approve a measure – and in this case we say we have ‘revoked our approval’ of the measure.
If we have decided to refuse or revoke approval to a measure, we will notify a supplier of this in writing using a decision notice. The decision notice will give the reasons for our decision and the following information:
Supplier licence number
Measure reference number
Date of completed installation
Installers and other parties in the supply chain may ask suppliers to share these notices as proof that a measure has been refused or revoked approval by Ofgem.
