Funding runs on a dual cost-cap structure: up to £15,000 per home for energy-performance upgrades (insulation, solar, ventilation) plus up to £15,000 for low-carbon heating — a combined ceiling of £30,000 per home. The scheme is funded to 31 March 2028, giving it the longest runway of any live grant. One practical note: councils receive annual allocations, so some pause applications between funding years once a year’s budget is committed — if your council is paused, register interest for the next release rather than assuming the scheme is closed.
The Warm Homes: Local Grant is England’s main publicly funded home-energy programme. Solar panels are the #1 funded measure. 271 local authorities are involved. Check whether your postcode qualifies.
DESNZ reports around 5,470 households upgraded and 11,250 measures installed to the end of July 2026 (up from ~5,100 households / 10,460 measures last month). Solar PV leads at 38%, insulation 24%, and batteries have risen to 18%. Regionally the South East leads (23% of upgraded homes), then the North West (19% — and the highest average measures per household at 2.33) and the East of England (14%). TrustMark holds ~14,700 lodged measures across ~6,700 households, so validated totals are likely to revise upward under DESNZ’s new methodology. Figures are provisional. Next release: Thursday 26 November 2026.
The Warm Homes: Local Grant (WH:LG) is an England-only Government programme that funds home-energy improvements for eligible owner-occupiers and private tenants. It is delivered through local authorities and covers a wide range of measures including solar panels, battery storage, insulation, heat pumps and smart controls.
Crucially, WH:LG is not applied for through Insulation Comparisons or through a central Government website. If your local authority is participating, they arrange and fund the works through their delivery partners. We help you understand eligibility and point you toward the official route.
Postcode eligibility: The Government publishes an eligible postcode dataset for WH:LG. Some areas have a postcode-priority route that does not require household income verification. Enter your postcode to check.

The Government publishes eligible postcode data. Not all postcodes are eligible — priority areas may not require income verification.
271 local authorities are involved in WH:LG — covering most of England. Some programmes may already be oversubscribed (e.g. Liverpool year two was at capacity as of mid-2026).
Contact your council directly or through their WH:LG delivery partner. Insulation Comparisons is not the application route — we help you understand eligibility.
A retrofit assessor will visit your property to confirm what measures are suitable and fundable.
Important — transparency: For Warm Homes Local Grant, councils arrange and fund the agreed works. We can help you understand eligibility and direct you to the official route. We can also match you with a private installer if you don't qualify or prefer not to wait.
No. ECO4 is a separate supplier-obligation scheme closing December 2026. WH:LG is publicly funded, delivered through local authorities, and covers different measures including solar and batteries that ECO4 did not cover.
Yes. Solar PV was the most-installed measure under WH:LG, accounting for 38% of all reported installations to end-July 2026, according to Government statistics published 30 July 2026.
Yes. Battery storage accounted for 17% of WH:LG installations to end-July 2026. It is typically funded alongside solar panels rather than as a standalone measure.
If your local authority has exhausted its WH:LG allocation or you don’t meet the eligibility criteria, you may qualify for ECO4 (still open to December 2026) or the Warm Homes Loan Scheme (Rollout developing — consumer products launching as lenders are approved). You can also compare private installation options through Insulation Comparisons.
