De-duplication of ECO measures

This note describes the ECO2 de-duplication process and outlines Ofgem E-Serve’s and the obligated suppliers’ responsibilities. It also outlines the general timeframes for this process.

Why we carry out de-duplication

We carry out de-duplication of ECO2 measures to make sure that all savings claimed under ECO2 reflect actual savings. When more than one measure of the same type is notified for the same address, there is a risk that the savings of one installation are claimed multiple times. Therefore we need to determine which of the duplicated measures are valid notifications and which are invalid notifications.
