This checker takes a few answers (your nation, whether anyone is on income-related benefits, in England whether household income is £36,000 or less, your EPC band and whether you own the home) and points you to the scheme most likely to fit. It runs entirely in your browser, sends nothing anywhere, and gives you a likely verdict rather than a guarantee.
After your result
The checker is a first filter, so read the scheme it names before you contact anyone. In England that is the Warm Homes: Local Grant, or ECO4 for some households on benefits until it closes on 31 December 2026. In Scotland it is the Home Energy Scotland loan. Each page covers what the scheme pays for on windows and how to apply. To compare every scheme across the four nations side by side, see our double glazing grants guide.
Why most people end up paying privately
The honest position is that grants reach a minority of households. With ECO4 winding down and the remaining schemes carrying strict income and EPC tests, the majority of homeowners will fund their windows themselves. That is not bad news on its own, because a well-chosen uPVC casement is already good value, but it does mean you should plan around the private cost rather than hope for funding. If you are comparing quotes, our guide on avoiding overcharging is worth a read before you sign.
Frequently asked questions
It gives a likely verdict, not a decision. In England it tests the headline conditions of the Warm Homes: Local Grant: a listed benefit or a household income of £36,000 or less, plus an EPC band of D to G. In Scotland, Wales and Northern Ireland it points you to the scheme for your nation and what it will and will not pay for on windows. The council or scheme provider decides after a full assessment of your income, your home and the local budget. The checker cannot see whether your council still has money: several, including Liverpool, Leeds and Stoke-on-Trent, have spent their funding for April 2026 to March 2027.
Choose "I am not sure" and the result will tell you what depends on it. You can look up your home's rating on the GOV.UK EPC register using your postcode. In England the band matters because the Warm Homes: Local Grant is only for homes rated D to G.
No. The Warm Homes: Local Grant also accepts homes in eligible postcode areas without an income test, and each council sets its own list. If the checker says you are unlikely to qualify in England, ask your council whether your postcode is on its list before you budget to pay privately.
