The Department of Energy Security and Net Zero consulted on the policy proposals for a household insulation scheme under the name "ECO+" in November 2022, according to Ofgem's account of the scheme's history1. The department later named Ofgem as the intended administrator of the scheme, which by the time of Ofgem's own consultation had been renamed the Great British Insulation Scheme1.
Ofgem's administration consultation ran for five weeks, opening on 11 May 2023 and closing on 16 June 2023, with a listed closed date of 17 June 2023 and a status of "Closed (with decision)"1. Responses were directed to gbisconsultation@ofgem.gov.uk, with Chandni Bhudia named as the contact1. The consultation document itself was published as a PDF of 459.86KB1.
The policy consultation that preceded it, run by the department under the ECO+ name, had its response published in March 20231. Ofgem's consultation also covered an amendment to ECO4, the energy company obligation scheme then in force1.
"The Department of Energy Security and Net Zero has named Ofgem as the intended Administrator of the Great British Insulation Scheme. Through this consultation, we are seeking views on our proposed administration of the scheme."
"This scheme was previously consulted on by the Department of Energy Security and Net Zero under the name 'ECO+' in November 2022."

Why it matters for households
The naming history matters because households and the people advising them will encounter the same scheme under two different labels. Material referring to ECO+ and material referring to the Great British Insulation Scheme describe the same policy line, consulted on by the department in November 2022 and then handed to Ofgem to administer1. The scheme sits alongside ECO4, which the Ofgem consultation also sought to amend, so the two obligations are connected in administration even though they are separate schemes1.
Who administers a scheme shapes how eligibility is checked, how delivery is verified and how complaints and compliance are handled. Ofgem's role as intended administrator places those functions with the energy regulator rather than with the department that designed the policy1. For a household, that distinction is practical rather than technical: it determines which body's rules and processes apply once work is carried out.
The department responsible for the policy is covered in our guide to DESNZ, and the wider landscape of support is set out under grants and schemes. Eligibility for the scheme as it now operates is covered in our guide to Great British Insulation Scheme eligibility, and its relationship to the earlier obligation in Great British Insulation Scheme vs ECO4.
