The Great British Insulation Scheme (GBIS) provides free or low-cost insulation for UK homes in council tax bands A–D (England) or A–E (Scotland/Wales). Unlike ECO4, GBIS has no income requirements.
A-D (England) A-E (Scotland/Wales)
Minimal contribution
Until March 2026
The Great British Insulation Scheme (GBIS) is a UK government initiative launched in 2023 to improve home insulation across England, Scotland, and Wales.
GBIS is unique because it has no income requirements — eligibility depends entirely on your property's council tax band and EPC rating. This makes the scheme accessible to a much wider range of households than ECO4. The scheme runs until March 2026 and provides free or heavily subsidized insulation measures.
Check your GBIS eligibility instantly. We connect you with government-approved installers who conduct free property assessments and manage the full installation process — often at no cost to you.
The Great British Insulation Scheme (GBIS) provides funding for insulation improvements to homes in council tax bands A-D (England) or A-E (Scotland/Wales) with EPC ratings D-G.
GBIS may be fully funded for households on qualifying benefits. Others may receive heavily subsidized insulation with a small contribution required.
GBIS focuses solely on insulation and has no income requirements (only council tax band limits). ECO4 covers broader improvements including heating systems and has income/benefit requirements.
You cannot receive funding from both schemes for the same measure, but you may qualify for both if you need different types of improvements.
The GBIS process typically takes 6-10 weeks from initial application to completed installation.
