ECO4 is a government obligation on energy suppliers running until March 2026. You may be eligible if you receive benefits such as Universal Credit, Pension Credit, Child Tax Credit, or Income-Based JSA, and your home has an EPC rating of D, E, F, or G. Eligible improvements include loft insulation, cavity wall insulation, boiler replacements, and first-time central heating.
GBIS provides free or heavily subsidised insulation to homes in council tax bands A–D in England and A–E in Scotland and Wales. It covers cavity wall insulation, loft insulation, flat roof insulation, and room-in-roof insulation. You do not need to be on benefits to qualify — it is available to a wider group of homeowners.
The Boiler Upgrade Scheme provides £7,500 towards an air source heat pump or ground source heat pump installation. The grant is applied directly by your MCS-certified installer, reducing the upfront cost. You must own your property and have a valid EPC to qualify.
Yes, in many cases you can combine grants. For example, you could receive ECO4 funding for insulation and separately apply for the Boiler Upgrade Scheme for a heat pump. However, you cannot use two grants for the same measure on the same property.
ECO4 applications typically take 2–4 weeks from initial survey to approval. The Boiler Upgrade Scheme is usually processed within a few days once your MCS installer submits the application. GBIS timelines vary by local authority but are generally 2–6 weeks.
For the Boiler Upgrade Scheme, yes — you must own your property. For ECO4 and GBIS, both homeowners and private tenants (with landlord permission) can apply. Social housing tenants may also qualify through their housing provider.
ECO4 runs until March 2026. The Boiler Upgrade Scheme has been extended to 2028. GBIS is currently funded through March 2026. Funding is allocated on a first-come, first-served basis, so applying early is recommended.
