How to Get a Roof Grant Under the Warm Homes Plan (UK 2026)
Eligible UK homeowners and tenants can claim £1,200–£7,500 toward roof insulation, EPC-uplift roof works and (in the lowest EPC and income bands) full reroof grants under the 2026 Warm Homes Plan — the successor scheme to ECO4 from April 2026. This is a 6-step plan: check eligibility, confirm EPC band, find a TrustMark-approved contractor, apply via the local authority delivery partner, get the roof works done, and submit the post-works EPC for grant settlement.
How do I get a roof grant under the Warm Homes Plan in 2026?
The 6-step UK 2026 application path:
- Check eligibility — EPC band D–G, household income under £36,000, or recipient of a qualifying benefit
- Confirm EPC band via gov.uk EPC register — grants are tiered to EPC band
- Find a TrustMark / PAS 2030 contractor — only these can claim the grant
- Apply via your local authority delivery partner — not directly to government
- Approval, then roof works — typically 4–8 weeks from approval to start
- Post-works EPC — contractor lodges the new certificate; grant pays out 6–8 weeks later
Typical award levels: roof insulation upgrade £1,200–£2,400 · EPC-uplift roof + insulation £2,800–£4,800 · full reroof + insulation (EPC F/G fuel-poor only) £5,500–£7,500.
Confirm you're eligible (2026 rules)
The Warm Homes Plan from April 2026 has three eligibility routes — you only need to qualify under one.
Route A: EPC band & income
Property in EPC band D, E, F or G AND household gross income under £36,000 (single-occupant) or £46,000 (multi-occupant). Both owner-occupied and privately-rented properties qualify; tenants need landlord consent for the works.
Route B: Qualifying benefit
Anyone in the household receives Universal Credit, Pension Credit, Income Support, Income-based JSA, Income-related ESA, Housing Benefit, Working Tax Credit or Child Tax Credit — with no income cap. Property must be in EPC band D–G.
Route C: Local authority "Flex" referral
Around 50% of UK local authorities operate a "Flex" route allowing them to refer households who don't qualify under Routes A or B but are in vulnerable circumstances (e.g. medical conditions exacerbated by cold homes, recent bereavement, single-parent households on tight budgets). Property still needs EPC D–G. Check directly with your council.
The full application path
Step 2: Confirm your EPC band
Search the gov.uk EPC register for your address. If your last EPC is more than 10 years old, get a fresh one (£60–£120, accredited assessor). The register confirms your current EPC band and predicted band after recommended works — the difference between these two numbers determines your grant level. Bands F and G qualify for the highest awards.
Step 3: Find a TrustMark / PAS 2030 contractor
Only contractors registered to TrustMark AND certified to PAS 2030:2023 for the relevant measure (Insulation: Pitched Roofs / Flat Roofs / Room-in-Roof / Loft) can claim under the scheme. Ask for both numbers up front. The TrustMark website has a postcode finder. Get 3 quotes — the lowest is rarely the best because grant-claiming admin overhead favours mid-priced fully-insured firms.
Step 4: Apply via the local authority delivery partner
Applications go through the local authority's appointed delivery partner (typically British Gas, E.ON Next, Octopus, EDF, or a regional installer). Your TrustMark contractor will tell you which partner covers your postcode. The partner runs the eligibility check, processes the grant, and pays the contractor on works completion. Do not pay the contractor up-front — the grant pays the contractor directly.
Step 5: Approval & roof works
Approval typically takes 3–5 weeks from a complete application. Works start 4–8 weeks after approval (contractor scheduling). Pitched roof insulation upgrades take 1–2 days; full reroof + insulation 5–10 days. The contractor must provide a PAS 2030 install certificate and as-installed photographs.
Step 6: Post-works EPC & grant settlement
The contractor commissions the post-works EPC (typically within 2 weeks of completion) and lodges it with the Energy Performance register. The grant pays out to the contractor 6–8 weeks after lodgement. You don't see the money in your bank account — the works are simply done at zero cost to you up to the grant cap, with any over-cap excess invoiced to you separately at quote time.
Typical 2026 grant levels for roof works
Awards are caps — the contractor's quote determines the actual amount, up to the cap. If the quote exceeds the cap, the difference is payable by the homeowner.
