Solar panel grants & schemes (UK 2026)

Six routes to cutting the upfront cost of a UK solar install in 2026 — and the ones that look like grants but aren't.

Home › Guides › Solar panel grants & schemes (UK 2026)

0% VAT — the only universal one

Until 31 March 2027, residential solar PV (and batteries fitted at the same time, or retrofitted from Feb 2024) is zero-rated for VAT. Your installer applies it directly — there's no application. On a £7,000 install that's a £1,400 saving versus the pre-2022 standard rate.

ECO4 — for low-income households (England, Scotland, Wales)

ECO4 is a supplier-funded scheme delivering free or heavily subsidised energy upgrades, including solar PV in some cases, to households on qualifying benefits or in EPC band D–G. It's not a cash grant — your installer claims the value from an obligated energy supplier.

Eligibility hinges on receiving Universal Credit, Pension Credit, Income Support, or being referred via a council 'flexible eligibility' route (LA Flex). The scheme runs to March 2026, with ECO5 expected to follow.

Home Energy Scotland Loan (Scotland)

Up to £6,000 interest-free for solar PV, plus up to £6,000 more for battery storage, repayable over 12 years. Scottish residents only, owner-occupier or private landlord. Combine with the cashback grant (up to £1,250 on solar) for households on qualifying benefits.

Nest scheme (Wales)

Free home energy improvements — including solar PV in qualifying cases — for low-income Welsh households, delivered by the Welsh Government via British Gas. Applies in EPC bands E–G; income or benefits criteria apply.

Smart Export Guarantee — not a grant but treated like one

SEG isn't a grant; it's a legal obligation on large suppliers to pay you for surplus electricity exported to the grid. Best 2026 rates run 12–15p/kWh on smart-tariff variants. Applying takes 10 minutes once your install is MCS-certified.

Schemes that aren't really grants

Be careful with: 'free solar' rent-a-roof deals (you don't own the panels, they can complicate resale), 0% interest finance (still a loan, often hides product markup), and council 'solar together' bulk-buy schemes (good prices, but the discount comes from volume, not subsidy).

Frequently asked questions

Is there a UK government grant I can claim directly?
No. There's no universal cash grant for solar in 2026. The closest things are ECO4 (supplier-funded, low-income) and the Home Energy Scotland Loan (Scotland only). The 0% VAT applies universally and is the largest single saving for most households.
Can I combine multiple schemes?
Yes — 0% VAT applies regardless. ECO4 and Home Energy Scotland support generally cannot be stacked on the same measure, but you can pair either with SEG and council top-ups.
Do I have to repay an ECO4 install if I sell?
No. ECO4 measures are not a charge on the property and don't need repaying. Keep the certificates for the buyer's solicitor.
