Great British Insulation Scheme
- Amount
- Free or £0 to £300 contribution
- Covers
- Cavity wall / loft insulation (the upgrade that makes cooling effective and cheap)
Who it's for
Homes in EPC bands D to G in council tax bands A to D (England, A to E Scotland)
How it works
Not a solar or AC grant directly, but insulation is the precondition that makes any cooling install work: a well-insulated room stays cool for hours after the AC cycles off. Pair this free measure with a bundle and your running cost drops further.
