What Solar Panel Grants Are Actually Available in 2026?
If you’re searching for free solar panels in the UK, here’s the honest answer: fully free installations exist, but only for a narrow band of low-income households. For everyone else, the government offers a patchwork of grants, tax breaks and export payments that can knock thousands off the cost — but you need to know which ones you actually qualify for.
We’ve gone through every current scheme as of April 2026, checked the eligibility criteria against the latest government guidance, and cut through the marketing spin you’ll find on most installer websites. Here’s what’s real and what’s not worth your time.
The Big One: Warm Homes Local Grant (England)
This is the most generous solar panel grant currently available in England. Launched as part of the government’s wider Warm Homes Plan, it can fund up to £15,000 of energy efficiency improvements — including solar panels — at no cost to eligible homeowners.
Who qualifies?
You need to tick all of these boxes:
Income: Household income of £36,000 or less in most areas, though the threshold varies by local authority. Some councils set it as low as £23,000 (Newcastle), while others go up to £38,000 (Isle of Wight). Most sit in the £31,000–£36,000 range.
Property: Must be privately owned (either by you or your landlord) with an EPC rating of D, E, F or G. If your home already has an A, B or C rating, you won’t qualify.
Location: England only. Your property must fall within the eligible postcodes for your local authority’s allocation.
Important caveats
You can’t simply request solar panels. The scheme aims to improve your home’s overall energy efficiency, so the assessor may recommend insulation before solar if your home isn’t well insulated. This makes sense from an energy-saving perspective, but it means you might not get solar panels even if that’s what you applied for.
The process typically takes two to six months from application to installation. You apply through your local council, not directly through the government. Average wait time from application to first contact is around 10 days.
How to apply
Go to gov.uk/apply-warm-homes-local-grant and enter your postcode. You’ll be directed to your local council’s application process. Have your latest energy bills and household income figures ready.
ECO4: Still Available, But Not for Long
The Energy Company Obligation (ECO4) scheme was originally due to end in March 2026, but the government extended it to 31 December 2026. After that, it’s done — there’s no ECO5 or successor scheme announced.
Who qualifies?
ECO4 targets low-income, fuel-poor and vulnerable households. You’ll typically need to be receiving means-tested benefits such as Universal Credit, Pension Credit, or Child Tax Credits, and your home must have an EPC rating of D, E, F or G.
The solar catch
Solar panels are technically an eligible ECO4 measure, but there’s a significant restriction: solar PV is only available where the property’s heating system is a heat pump, high heat retention electric storage heaters, or another electric heating system. If you have a gas boiler (which most UK homes do), you won’t get solar panels through ECO4.
This explains why solar makes up just 5.75% of all ECO4 measures delivered so far — only 38,005 solar installations out of 660,487 total measures. The scheme is overwhelmingly used for insulation and heating upgrades.
How to apply
Contact your energy supplier directly, or use the government’s Simple Energy Advice service. Your supplier will arrange an assessment of your property.
0% VAT on Solar Panels
This isn’t a grant you apply for — it’s a tax break that’s automatically applied by your installer. Since April 2022, solar panel installations in the UK have carried 0% VAT instead of the standard 20% rate.
How much does it save?
On a typical 4kW solar panel system costing around £6,500, the 0% VAT saves you roughly £1,300 compared to the standard rate. On a larger system with battery storage costing £11,000+, you’re saving over £2,000.
The deadline
The 0% rate is confirmed until 31 March 2027, after which it’s scheduled to revert to 5%. There’s been no indication the government will extend it further. If you’re planning to install solar panels anyway, doing it before April 2027 saves you a meaningful amount — a 5% rate on an £11,300 system adds roughly £565 to the bill.
This applies across the whole of the UK, including Northern Ireland (which was added in May 2023).
Smart Export Guarantee (SEG): Get Paid for Surplus Electricity
The SEG isn’t a grant — it’s an ongoing income stream. Once your solar panels are generating electricity, any surplus you don’t use gets exported to the grid, and your energy supplier pays you for it.
Current rates (April 2026)
Rates vary enormously between suppliers and tariff types:
Best fixed rates: E.ON Next Export Exclusive pays 16.5p/kWh. Octopus Energy Outgoing and OVO both offer around 15p/kWh.
Variable/time-of-use rates: If you have a home battery, tariffs like Octopus Flux can pay up to 30p/kWh during peak demand hours. This requires you to store solar energy during the day and export it in the evening when the grid needs it most.
Bottom of the market: Some suppliers offer as little as 1–3p/kWh. Always shop around — the difference between the best and worst tariff could be £150–£200 per year in export earnings.
Requirements
Your installation must be MCS-certified (which any reputable installer will be) and you need a smart meter that can record export data. Registration is free and you can switch SEG providers without changing your electricity supplier.
Warm Homes Plan: Low-Interest Loans for Everyone
Launched in January 2026, the government’s Warm Homes Plan is a £15 billion programme aiming to upgrade 5 million homes by 2030. Unlike the grants above, the loan element is available to all homeowners regardless of income.
The Warm Homes Fund offers 0% interest loans for solar panels, battery storage, heat pumps and insulation. The details on loan amounts and application process are still being rolled out through 2026, so check the latest guidance on gov.uk.
For low-income households, the plan also includes fully funded packages worth up to £30,000 through the Local Grant element described above.
Scotland: Home Energy Scotland
Scottish homeowners have their own scheme through Home Energy Scotland. If your household income is £36,000 or less, you can get up to £6,000 towards a solar panel installation — split as a £1,250 grant and a £4,750 interest-free loan.
Apply through Home Energy Scotland’s website or call their advice line. They’ll assess your property and talk you through what funding you’re eligible for.
Wales: Nest Scheme
The Welsh Government’s Nest scheme offers advice and funding for solar panel installation. To qualify, your home needs an EPC rating of E or lower (or D if someone in the household has an eligible health condition) and your household income must be £38,456 or less.
Contact Nest directly for an assessment — they’ll tell you whether solar panels are recommended for your property and what funding is available.
Northern Ireland
If you’re in Northern Ireland, there are currently no specific solar panel grants available. The 0% VAT does apply, and you can access the Smart Export Guarantee. The Boiler Replacement Scheme occasionally includes renewable energy measures, but solar PV isn’t consistently covered.
Schemes That Don’t Exist (Despite What You Might Read)
A word of warning: many installer websites and lead generation sites advertise “free solar panel schemes” or “government solar panel grants” that either don’t exist or are wildly misleading. Common ones to watch out for:
“Free solar panels” — These were common under the old Feed-in Tariff (ended 2019) where companies would install panels on your roof for free in exchange for the FIT payments. This model is dead. Anyone still advertising it is either out of date or misleading you.
“Government solar panel grant — apply now” — Many of these sites are lead generation forms that sell your details to installers. They’re not government services. The only legitimate application route for the Warm Homes Local Grant is through gov.uk and your local council.
Inflated grant figures — Some sites quote “up to £30,000” without making clear that this is the maximum for the most extensive whole-house retrofits, not a typical solar panel grant.
What Should You Actually Do?
Here’s our honest recommendation based on where you sit:
Low income, poorly insulated home: Apply for the Warm Homes Local Grant first. It’s the most generous scheme and could cover your entire installation cost. Also check ECO4 before it ends in December 2026, particularly if you have electric heating.
Middle income, decent home: You won’t qualify for the major grants. Your best bet is the 0% VAT saving (act before March 2027), a competitive SEG tariff, and potentially a 0% interest loan through the Warm Homes Fund when it’s fully rolled out. On a £7,000 system, you’re looking at roughly £1,400 in VAT savings and £100–£250 per year in SEG payments.
Scotland or Wales: Apply for your regional scheme first (Home Energy Scotland or Nest) before looking at UK-wide options.
Everyone: Get at least three quotes from MCS-certified installers. The biggest variable in what you’ll pay isn’t which grant you get — it’s which installer you choose. We’ve seen quotes for identical systems vary by 40% or more.
