ECO4: The UK’s Only Route to Completely Free Solar Panels
ECO4 (Energy Company Obligation, fourth phase) is the only scheme in 2026 that can cover 100% of your solar installation — panels, survey, labour, and MCS certification all included, at no cost to you. It’s funded via a regulatory levy on big energy suppliers (British Gas, Octopus, EDF, OVO, and others), managed by Ofgem. As of April 2026, ECO4 has already delivered over 950,000 energy efficiency measures across the UK.
You qualify if someone living in your home receives one of these benefits and your property has an EPC rating of D, E, F, or G:
- Universal Credit
- Pension Credit
- Child Tax Credit
- Income Support
- Income-based Jobseeker’s Allowance
Not on benefits? Ask your local council about ECO4 Flex (LA Flex) — a council-administered extension that can cover households earning under roughly £31,000, or those with health vulnerabilities. It’s free to check and absolutely worth a call.

Warm Homes: Local Grant — Up to £30,000 for Low-Income Homes
Launched as part of the government’s landmark £15 billion Warm Homes Plan in January 2026, the Local Grant is the successor to the now-closed HUG2 scheme. It’s currently open to homeowners and private tenants in England with a household income under £36,000 (or on means-tested benefits) and an EPC of D–G. The maximum funding is £30,000 per property — covering solar panels, insulation, heat pumps, and other energy improvements.

0% VAT on Solar Panels: The Saving Every Homeowner Gets Automatically
This one requires zero admin on your part. Since April 2022, all residential solar panel installations carry zero VAT — saving you roughly £1,000–£2,000 on a typical 4kW system (that’s the full 20% knocked straight off). It runs until at least March 2027, and every installer must already reflect this in their quotes. If yours doesn’t, ask them why.

Smart Export Guarantee (SEG): Get Paid for the Power You Don’t Use
Once your panels are installed, the SEG pays you for any surplus electricity you export to the grid. Rates vary significantly between suppliers — shopping around can make a real difference of hundreds of pounds a year. Here’s where the top tariffs sit in June 2026:

Rates verified June 2026. Variable tariffs may change. You can switch SEG providers at any time — no exit fees apply.
A typical household earns £150–£400 per year from SEG exports. Combined with reduced energy bills, most 4kW systems pay for themselves within 6–9 years, then keep saving for a further 15–20 years on top.
Scotland, Wales & Northern Ireland: What’s On Offer?
🏴 Scotland
Home Energy Scotland offers a £1,250 grant plus a £4,750 interest-free loan (£6,000 total) for households earning up to £36,000 per year.
🏴 Wales
The NEST scheme provides fully funded solar panels for homes with an EPC of E or below and a household income of £38,456 or less.
🇬🇧 Northern Ireland
No direct solar grant currently. However, the 0% VAT saving on all installations still applies and makes a meaningful difference to upfront costs.

☀️ ECO4 Closes 31 December 2026 — Don’t Leave It Too Late

Who qualifies for solar panel grants in the UK in 2026?
It depends on your income, the benefits you receive, and your home’s EPC rating. ECO4 (open until December 2026) covers households on Universal Credit, Pension Credit, Income Support, or income-based JSA with an EPC of D–G. The Warm Homes: Local Grant targets those in England earning under £36,000 with a low EPC. And the 0% VAT saving applies to every UK homeowner automatically — no means-test, no application required.
Is ECO4 still available in 2026?
Yes — but only until 31 December 2026. Waiting lists are growing in most areas, so if you think you qualify, apply now rather than waiting until autumn. Contact your energy supplier directly (British Gas, Octopus, EDF, OVO, etc.) or ask your local council about their ECO4 Flex scheme. There’s no cost to check your eligibility, so there’s nothing to lose.
How much can solar panels save on my energy bills?
A typical 4kW system cuts energy bills by over £800 per year. The Smart Export Guarantee adds a further £150–£400 per year in export payments depending on the tariff you choose — with the best rate hitting 32.17p/kWh in June 2026. With payback periods of 6–9 years and panels lasting 25+ years, the long-term financial case is hard to argue with.
