Great British Insulation Scheme

About the scheme

The Great British Insulation Scheme is a new government energy efficiency scheme (formerly known as ECO+) that will be administered by Ofgem. It is designed to deliver improvements to the least energy-efficient homes in Great Britain to tackle fuel poverty and help reduce energy bills.

The scheme complements the Energy Company Obligation (ECO4) scheme, yet unlike ECO4’s ‘whole house’ approach, this scheme will mostly deliver single insulation measures.

As well as supporting low-income and vulnerable households, it will also be available to those living in homes with an Energy Performance Certificate rating of D-G, and within Council Tax bands A-D in England and A-E in Scotland and Wales.

The scheme will work by placing an obligation on medium and large energy companies to deliver measures that result in reduced energy usage. It is intended to run from around April 2023 until March 2026.
