What is the Great British Insulation Scheme? (GBIS)

GBIS (formerly known as ECO+) is a government energy efficiency scheme administered by Ofgem, on behalf of the Department for Energy Security and Net Zero. GBIS will run from July 2023 – March 2026.

The scheme delivers improvements to the least energy-efficient homes across Great Britain (with an energy performance certificate (EPC) of D to G) and aims to help reduce energy bills and carbon emissions by providing free or cheaper insulation to eligible households. Depending on eligibility and current insulation levels, some households may need to make a contribution to the cost of the measure.

The scheme complements the Energy Company Obligation (ECO4) scheme, however unlike ECO4’s ‘whole house’ approach, GBIS will mostly deliver single insulation measures. GBIS is available to homes within Council Tax bands A-D in England or A-E in Scotland or Wales, as well as low-income and vulnerable households.


Information for installers

There are standards that installers must follow for the installation of GBIS measures. TrustMark registered businesses must be certified as compliant with PAS 2030:2019 by a PAS accredited scheme provider or certification body. All installers registered with TrustMark must deliver energy efficiency measures within the scope of PAS 2035:2019 and PAS 2030:2019.

TrustMark is responsible for ensuring installers comply with PAS and MCS standards and that appropriate guarantees are in place.

Suppliers and installers are responsible for checking and confirming each individual household’s SAP bands, via an RdSAP assessment which should take place at the premises before determining the appropriate measures to install.


You can find further information and read the guidance document for the scheme on the Ofgem website.
