Great British Insulation Scheme - GBIS

The Great British Insulation Scheme is a new government energy efficiency scheme (formerly known as ECO+). 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 install measures that result in reduced energy usage. It is intended to run  until March 2026.

West Sussex have a statement of Intent published which allows eligible residents to take part in the scheme. Many energy supplier sare still finalising their offer, but you can register your interest. Once published further information will be found here. Further information is available on the OFGEM website. external link icon
