Ofgem published its consultation decision on the administration of the Great British Insulation Scheme and amendments to ECO4 on 22 August 20231. The decision sets out the regulator's final position on how it will administer the two policies, following a consultation that opened on 11 May 2023 and closed on 16 June 20231.
The consultation drew 17 responses from what Ofgem describes as a variety of stakeholders, including energy suppliers, installers and an independent organisation promoting energy efficiency1. The published document is Ofgem's consultation response, which it says sets out its final position1. In it, Ofgem states that it summarises stakeholder views, presents the points raised and responds to that feedback, then outlines the outcome of the consultation and, where relevant, how it has changed its approach1. The main document is a PDF of 545.68KB1.
"The document below is our consultation response which sets out our final position."
The decision covers administration of the Great British Insulation Scheme and amendments to ECO4, the current Energy Company Obligation scheme1. Ofgem is the energy regulator for Great Britain; its role and remit are set out in our guide to what Ofgem does and what it covers. The wider framework of home energy rules sits within UK home energy regulation and policy.
Why it matters for households
The Great British Insulation Scheme and ECO4 are the two main routes through which insulation and related efficiency measures are funded by energy suppliers under obligation. How Ofgem administers them determines how suppliers report and demonstrate compliance, and how the schemes are monitored. For a household, the practical effect is on the delivery of measures under these schemes rather than on the eligibility rules themselves, which are set elsewhere. The decision does not itself change what a home can receive; it concerns the administrative arrangements the regulator will apply. Households weighing the two schemes against each other can read our comparison of the Great British Insulation Scheme vs ECO4, and the relationship between fabric measures and a home's ability to reduce reliance on bought energy is covered in insulation, glazing and energy independence.
