Home Insulation Grants 2026: Full UK Eligibility Guide

The grant picture changed in 2026. The Great British Insulation Scheme closed on 31 March 2026, leaving two main national schemes plus various local programmes. Both remaining schemes target the least efficient homes, those rated EPC D to G, owned or privately rented by lower-income households. The table below compares them at a glance, and the sections that follow explain who qualifies and how to apply.

The main change for 2026 is the closure of the Great British Insulation Scheme on 31 March 2026, which had offered wider eligibility, including some middle-income homes in lower council tax bands, and typically funded a single measure. Its closure leaves two national schemes that both target lower-income households more tightly. The other shift is timing: ECO4 now has a firm end date of 31 December 2026, so it is the scheme with the shortest remaining window, while the Warm Homes Local Grant runs on to 31 March 2028. For homeowners this means two things. If you would have used GBIS, you may need to check the income and benefit tests more carefully than before, because the remaining schemes are less generous on who qualifies. And if you are eligible for ECO4, the closing date makes it the one to act on first. Insulation Quotes Walsall tracks these changes so the guidance here stays accurate.

ECO4 is the Energy Company Obligation, funded by energy suppliers. It fully funds insulation and heating upgrades for eligible households, so you pay nothing. You qualify if you receive a means-tested benefit, or through your local council's LA Flex criteria even without benefits. ECO4 takes a whole-house approach and can fund expensive measures such as solid wall insulation in full, which makes it valuable for older homes. It closes on 31 December 2026, so it is the scheme to act on first if you are eligible.

The Warm Homes Local Grant is administered locally rather than by energy suppliers. It offers up to £15,000 for energy-efficiency measures, including insulation, plus up to £15,000 for low-carbon heating. You qualify if your household income is below £36,000 or you receive a means-tested benefit, you own or privately rent your home, and it is rated EPC D to G. The scheme runs until 31 March 2028, giving it a longer window than ECO4. Delivery varies by area: in the West Midlands, including Walsall and Dudley, it is handled by Acton Energy.

Beyond the national schemes, many councils run their own support. In Walsall, the Walsall Energy Action Project (WEAP) offers free home energy visits with thermal imaging to show where heat escapes. Staffordshire residents near Cannock can use the Staffordshire Warmer Homes programme, and Telford homeowners can access Warm and Well Telford. These local schemes often act as a front door, assessing your home and pointing you to the national grant you qualify for.

If you might qualify for more than one scheme, the order you check them in matters. ECO4 is fully funded, so for eligible low-income households it is the most generous option, and it closes earliest, in December 2026. That makes it the scheme to act on first. The Warm Homes Local Grant has a longer runway to March 2028 and a wider income gateway, so it is the natural fallback if ECO4 does not fit. Local advice services such as WEAP sit alongside both and can point you to the right one. The summary below shows the sensible order of priority for most Walsall homeowners weighing up their options.

• Check ECO4 first if you are on a means-tested benefit or could qualify through LA Flex, because it is free and closes soonest.
• Check the Warm Homes Local Grant next if your income is below £36,000 but you do not qualify for ECO4.
• Use a free local audit such as WEAP if you are unsure which route fits your home.
• Plan to self-fund the fastest-payback measures if no grant applies, starting with loft insulation.

Eligibility for the two national schemes turns on a small set of tests: a qualifying benefit, a household income figure, your EPC rating and your tenure. The table below maps the main entry points so you can see at a glance which scheme each situation points to. Every route still requires a home rated EPC D to G that you own or privately rent.

1. 1Check your EPC rating (free on the government EPC register) and confirm it is D to G.
2. 2Check your income and benefits against the scheme thresholds above.
3. 3Apply through the relevant route, or use a local advice service like WEAP to be pointed the right way.
4. 4Have the work done by a TrustMark-registered, PAS 2035 installer.

Knowing why applications fall down helps you avoid wasted time. The most frequent reason is an EPC rating that is too high: both ECO4 and the Warm Homes Local Grant target homes rated D to G, so a property already rated A to C will not usually qualify. The second is the income or benefit test, where a household sits just above the £36,000 threshold for the Warm Homes Local Grant and is not on a qualifying benefit. The third is tenure, where a private tenant cannot get the landlord to agree to the work. Less obvious snags include an out-of-date EPC certificate that no longer reflects the home, or a property type that does not suit the proposed measure, such as a wall that cannot safely take cavity fill. Checking your EPC on the free government register and confirming your figures before you apply heads off most of these. If one scheme rejects you, it is still worth checking the other, as their tests differ.

Working out which 2026 grant fits your home takes three quick checks. First, find your EPC rating on the government's free register: ECO4 and the Warm Homes Local Grant both target homes rated D to G, so a property already rated A to C will usually fall outside them. Second, check your household income and benefits, because ECO4 leans on means-tested benefits or a council's LA Flex rules, while the Warm Homes Local Grant uses an income threshold of around £36,000. Third, confirm your tenure, since owner-occupiers and private tenants with landlord permission can apply, but the route differs. If one scheme rejects you, it is still worth checking the other, as their tests are not the same. Once you know which grant applies, Insulation Quotes Walsall can connect you with vetted, accredited installers who handle the relevant paperwork, so funded work is arranged without the guesswork.
