Solar Panel Grants UK 2026: ECO4, 0% VAT, Free Solar Schemes and What You Can Actually Claim
There is no single large government grant for solar panels in England in 2026. The Feed-in Tariff closed in 2019 and has not been replaced with a direct capital grant. But there are several legitimate ways to reduce the cost of solar — some worth thousands of pounds — and many homeowners miss them by not knowing they exist.
This guide covers every current UK solar incentive, who qualifies, how to apply, and what each is realistically worth.
In this guide, you'll learn:
Summary: What's Available in 2026
| Scheme | Value | Who qualifies | Where |
|---|---|---|---|
| 0% VAT on solar installation | ~£1,000–£2,000 saving | All homeowners | England, Scotland, Wales |
| ECO4 (free solar) | Full system cost | Low income, certain benefits | England, Scotland, Wales |
| Smart Export Guarantee | £150–£550/year | All solar homeowners with smart meter | England, Scotland, Wales |
| Home Energy Scotland grant | Up to £7,500 | Scottish homeowners | Scotland only |
| Warm Homes Programme | Varies | Low income, Wales | Wales only |
| Green Deal Finance | Loan, not grant | All homeowners | England, Wales |
0% VAT on Solar Installations
This is the most significant universal incentive. Since April 2022, solar panels, battery storage, and heat pumps all qualify for 0% VAT when installed on residential properties in Great Britain. Previously these attracted 5% VAT.
On a £6,500 installed solar system, 0% vs 20% standard VAT saves £1,083. On a combined solar + battery system at £13,000, the saving is £2,167. This is not a grant you apply for — it is automatically applied by your installer. Make sure your quote explicitly states 0% VAT; any installer charging 20% VAT on a residential solar installation is either misinformed or making an error.
The 0% rate applies to: solar panels, battery storage (installed with or after solar), scaffolding costs as part of a solar installation, and inverters and associated equipment.
ECO4: Free Solar for Low-Income Households
The Energy Company Obligation 4 (ECO4) scheme, running until March 2026 (with likely extension under successor schemes), requires large energy suppliers to fund energy efficiency improvements for low-income and fuel-poor households. Solar panels are eligible measures under ECO4.
Who qualifies for ECO4 solar:
- Households receiving means-tested benefits (Universal Credit, Income Support, Pension Credit, Housing Benefit, Tax Credits)
- Households with an EPC rating of D, E, F, or G
- Households referred by local authorities under the LA Flex flex route
How to access ECO4: Contact a registered ECO4 installer or your energy supplier directly. They will conduct a survey to confirm eligibility and identify the most appropriate measures. Solar is typically funded alongside insulation, as the scheme prioritises whole-house energy efficiency. Be cautious of cold-calling companies claiming ECO4 funding — always verify the installer is Trustmark-registered and check with your local council.
ECO4 is being replaced by the Warm Homes Plan from 2025–2026. If you qualify, apply now — the successor scheme's solar eligibility criteria and funding levels may differ.
Smart Export Guarantee Payments
The SEG is not a grant but is ongoing income every solar home is entitled to — and many miss it simply by not registering. Every licensed UK electricity supplier with 150,000+ customers must offer an export tariff. Rates reach 15p/kWh with the best suppliers.
A 4kW system without battery storage exports approximately 2,400–2,500 kWh/year. At 15p/kWh that is £360–£375/year in income — for the 25-year life of the system that is £9,000+ in export payments. Full registration guide and rate comparison: Smart Export Guarantee guide →
Scotland: Home Energy Scotland Grants and Loans
Scotland has significantly more generous solar incentives than England through Home Energy Scotland (HES), operated by the Scottish Government:
- Grant: Up to £7,500 for solar PV installation (subject to income and property criteria)
- Interest-free loan: Up to £17,500 repayable over 10 years at 0% interest for solar and other renewable measures
- Combined grant + loan: Many Scottish homeowners use both — the grant reduces capital cost and the loan covers the remainder interest-free
Apply via Home Energy Scotland: 0808 808 2282 or homeenergyscotland.org. Scottish homeowners have meaningfully better economics for solar than English homeowners due to these incentives — a £6,500 system with a £3,000 grant becomes a £3,500 net investment.
Wales: Warm Homes Programme
The Welsh Government's Warm Homes Programme provides funding for energy efficiency and renewable energy measures for low-income households. Solar panels are eligible measures under the Nest and Arbed schemes. Contact Nest (0808 808 2244) to check eligibility.
Local Authority and Green Finance Schemes
Several additional routes exist that many homeowners overlook:
- Local authority grants: Some councils run their own solar grant schemes, often funded by Shared Prosperity Fund or UKSPF allocations. Check your local council's website for current schemes — these vary widely and change regularly.
- Green Deal Finance: A government-backed loan scheme allowing homeowners to finance solar with repayments attached to the energy bill rather than the homeowner. Interest rates are typically 6–9% — not cheap, but accessible for those without upfront capital.
- Social housing solar schemes: Housing associations and local authorities are installing solar on social housing at pace. If you rent from a housing association, ask them directly about solar installation plans.
What Is NOT Available in England in 2026
To set realistic expectations:
- No universal capital grant for solar in England. The old Low Carbon Buildings Programme and similar schemes have not been replaced. There is no grant available to standard English homeowners who do not qualify for ECO4.
- Feed-in Tariff is closed to new applicants. If you missed it, you missed it. The SEG is the current export payment scheme.
- No boiler upgrade equivalent for solar. The Boiler Upgrade Scheme (BUS) covers heat pumps and biomass boilers — not solar panels.
- Promises of "free solar" from cold callers are almost always misleading for households that do not qualify for ECO4. Free solar is real — but only for qualifying low-income households through registered installers.
Combine incentives for maximum impact. A Scottish homeowner can stack: 0% VAT (saving £1,000+), Home Energy Scotland grant (up to £7,500), interest-free HES loan, and Smart Export Guarantee payments (£300–£550/year). The effective out-of-pocket cost of a solar system can be very low with all incentives combined.
Frequently Asked Questions
Is there a solar panel grant in the UK in 2026?
Yes, but it depends on where you live and your circumstances. In Scotland, grants of up to £7,500 are available through Home Energy Scotland. In England and Wales, low-income households may qualify for free solar through ECO4. All UK homeowners benefit from 0% VAT on installation (saving £1,000–£2,000) and Smart Export Guarantee payments for surplus electricity exported to the grid.
Who qualifies for free solar panels in the UK?
Free solar panels in England and Wales are available through ECO4 to households receiving means-tested benefits (Universal Credit, Pension Credit, Income Support, Housing Benefit, Tax Credits) and with an EPC rating of D or below. Scottish homeowners have access to Home Energy Scotland grants regardless of benefit status, subject to property criteria.
What happened to the solar panel Feed-in Tariff?
The Feed-in Tariff closed to new applicants in April 2019. Existing FiT recipients continue receiving their guaranteed generation and export payments for their full 20-year term. New solar installations since then register for the Smart Export Guarantee instead, which pays only for electricity exported (not generated) at market rates of 12–15p/kWh in 2026.
