Scheme closed

Great British Insulation Scheme (GBIS): Closed

The Great British Insulation Scheme (GBIS) ended on 31 March 2026. It funded insulation only, never solar panels. If you are looking for help with insulation or solar now, the live routes are ECO4 (until 31 December 2026, for low-income and fuel-poor households) and Warm Homes: Local Grant (council-run, England only).

Funding amount

None: GBIS closed to new work on 31 March 2026.

Warm Homes: Local Grant (England): owner-occupied or privately rented homes rated EPC D to G, household income usually £36,000 or less, where the council takes part

Not eligible if

New GBIS applications (the scheme ended on 31 March 2026)
Solar panels were never funded by GBIS

Step by step

How the application works

Check ECO4

ECO4 has no single application form: contact your local council, if it takes part, or any obligated energy supplier. Suppliers decide which measures to fund after a retrofit assessment, and solar is never guaranteed.

Check Warm Homes: Local Grant

In England, apply through gov.uk/apply-warm-homes-local-grant. Your council then contacts you. Not every council runs it.

Paying for solar yourself

Home solar panels and batteries in Great Britain carry 0% VAT until 31 March 2027, then 5%. We quote every line up front.
