ECO3 appropriate guarantees

This document lists the guarantees that Ofgem has reviewed and consider to meet the criteria for an appropriate guarantee under the Energy Company Obligation (ECO).

In preparation for the new ECO3 scheme, we are in the process of reviewing this document. As part of this review we are exploring how the new Park Home measure could benefit from guarantee protection during ECO3. Once we have made a decision on this, the appropriate guarantee list will be updated as required. At the time of publication, the appropriate guarantee list remains unchanged in relation to all other ECO measure types.

Update 7 June 2018 (Version 8)

The Version 8 (June 2018) of this document was created for the extension to the ECO2 scheme, known as ECO2t, and reflects that GDGC ECO Installer Guarantee (EEGGDG06) has been superseded by GDGC Domestic Property Insurance Backed Guarantee (GDGQAS01). This new code should be used for measures installed from 01 May 2018 with a GDGC guarantee.

In this update there have been no changes to the guarantee providers that provide ECO appropriate guarantees.

You can view the previous versions of ECO appropriate guarantees on our website. 

Update 14 November (Version 8.1)

The Version 8.1 (November 2018) of this document was created to reflect Ofgem’s new address.
