Solar Panel Grants UK 2026: What's Real, Who Qualifies

Solar Panel Grants UK in 2026: The 6 Routes That Exist

There are 6 official routes, and only 3 of them put free panels on a roof. Here's each one as it stood on October 29, 2026.

The government's Warm Homes Plan also announced a "rooftop revolution" aiming to put solar on up to 3 million more homes by 2030. The plan says its measures taken together could do this. That's a target, not a new grant you can apply for. The plan's funding table sets aside £960 million for low-income home grants in 2026 to 2027 and £1 billion a year for the three years after, and says those grants will focus on solar, batteries and insulation.

Who Gets Free Solar Panels: Grantsights Analysis of the Warm Homes: Local Grant

Solar is now the single most common measure in England's main low-income grant: 4,297 homes had panels fitted by the end of July 2026. Grantsights analysis of Table 2 of the DESNZ Warm Homes: Local Grant statistics shows what councils have installed so far.

Source: DESNZ, Warm Homes: Local Grant statistics, August 2026, Table 2 (England, April 2025 to July 2026, 67 of 74 grant recipients reporting). "Other insulation, windows and doors" is the remainder of the published total.

Those 11,247 measures went into 5,469 homes, and 79% of those homes got solar panels. A case in point: in England's main low-income scheme, a typical solar measure cost £7,200 and the household paid nothing. That's the clearest evidence that "free solar panels" can be real in England. It's also the clearest evidence of scale: 4,297 homes in 16 months, against 296,000 solar installations across the UK in the last 12 months.

Who qualifies. The GOV.UK Warm Homes: Local Grant page (opens in a new tab) says the home must be in England, privately owned (by you or your landlord) and rated EPC D, E, F or G. Household income must usually be £36,000 a year or less, though you might still qualify above that if you live in certain postcode areas or someone in the household gets certain benefits. If you have a landlord, they may need to pay for some of the work.

What happens. If your council has funding, it arranges a home survey and decides which upgrades suit your home. Solar is one option alongside insulation, heat pumps and controls, so you can't insist on panels. The council organises and pays for the agreed work, and GOV.UK says it usually contacts you within 10 working days. The assisted digital helpline is 0800 098 7950.

DESNZ says 271 councils, over 97% of eligible councils in England, have funding through 74 projects, with £500 million allocated from April 2025 to March 2028.

ECO4 and Solar: A Big Contributor That's About to Stop

ECO4 has put solar PV on more low-income homes than any other scheme. According to the DESNZ June 2026 data (Table 1.6), it delivered 65,484 solar PV measures between April 2022 and April 2026, 6.3% of its 1,043,846 measures. Most went in as part of a package with insulation or heating, not on their own.

But ECO4 ends on 31 December 2026, and the government has said there'll be no successor supplier obligation. Suppliers' notified savings already exceed the scheme's total target, so few are taking on new whole-house jobs. Ofgem says ECO isn't a grant scheme: suppliers choose what to fund, and some ask for a contribution. Our ECO4 scheme guide explains who qualifies and how to check an offer before you sign.

Help for Everyone Else: VAT, Export Payments, Loans and Plug-in Panels

Most UK homes don't qualify for a free installation. Four official measures still cut the cost, and the first saves 5% on the price compared with the rate that returns in April 2027.

1. 0% VAT until 31 March 2027. HMRC's VAT Notice 708/6 (opens in a new tab) says the installation of energy-saving materials in homes, including solar panels and, from 1 February 2024, batteries, is zero-rated from 1 May 2023 to 31 March 2027. From 1 April 2027 it reverts to 5%. The catch: the relief applies when an installer supplies and fits the materials. Panels you buy from a retailer and fit yourself are charged at the standard rate.

2. The Smart Export Guarantee (SEG). Ofgem's SEG guidance for generators (opens in a new tab) says licensed suppliers must offer a tariff to eligible small generators, the rate must always be above zero, and you can choose any SEG supplier, not just your own. Installations must be in Great Britain and no bigger than 5MW. Each supplier sets its own rate and contract length, so shop around.

3. The Warm Homes Loan Scheme. Launched on 28 October 2026, the Warm Homes Loan Scheme (opens in a new tab) is open to homeowners anywhere in the UK, including Northern Ireland. The government's factsheet lists maximum loans of £15,000 for solar panels and £15,000 for a battery, offered by 10 lenders, with rates up to 5 percentage points below regular loans and some loans interest-free. Repayment can run up to 30 years with some lenders. You apply to a lender (directly, through an installer or through your mortgage provider), and an MCS certified installer must do the work.

4. Plug-in solar. A government press release on August 27, 2026 said plug-in solar panels are legal to buy and install in Great Britain, and could save households up to £110 a year. They're small balcony-style panels that plug into a socket, not a grant, but they're the only official option for many renters.

What a typical system costs. Home Energy Scotland's solar panels page (opens in a new tab) puts the average Scottish system at around 4kWp and about £6,500 installed, and gives two payback ranges on the same page: 5 to 10 years in its key facts and 8 to 12 years in the main text. That's close to the £7,200 average cost of a Warm Homes: Local Grant solar measure in England.

Where Solar Is Going In: Grantsights Analysis by Region

The South East added 39,339 solar installations in the year to September 2026, more than four times London's 9,226. Grantsights analysis of Table 4 of the DESNZ ET 6.3 data shows every nation and English region, using the cumulative count at the end of September 2025 and September 2026.

Source: DESNZ, Energy Trends ET 6.3, solar photovoltaics deployment, October 2026 update, Table 4 (all installations by region) and Table 3 (domestic installations by parliamentary constituency, summed by region by Grantsights). Regional rows don't add to the UK total because 19,081 installations are unallocated to a region. Provisional.

According to the DESNZ September 2026 data, the UK now has 2.16 million solar installations and 23.4GW of capacity. Domestic systems make up 1,781,735 installations but only 31% of capacity, because solar farms are much bigger. Almost 200,000 homes added panels in the last 12 months, and 2025 was the biggest calendar year on record with 269,500 installations.

The pattern matches house type and ownership: growth is fastest in the North East, Wales and the Midlands, and slowest in London, where flats and rented homes make rooftop solar harder. Put the two tables together and the honest answer is plain: grant-funded solar is a small slice of a market that's growing on its own, so most people who want panels will pay for them, helped by 0% VAT and SEG payments.

What GOV.UK Doesn't Tell You About Solar Panel Grants

GOV.UK lists each scheme on its own page. What it doesn't say in one place is how they fit together for someone deciding now.

"Government-backed" usually means a loan, not a grant. From 28 October 2026, adverts can truthfully say solar is available with government backing. That's the Warm Homes Loan Scheme: you repay it. The factsheet's own example is a £10,000 loan, so read the total amount repayable, not just the monthly figure.

The VAT deadline is the one most buyers underestimate. On a £7,000 job, going from 0% to 5% VAT after 31 March 2027 adds about £350. The date that counts is the installation, so if you want panels anyway, leave time for surveys and scheduling before March.

Free solar is real, but you don't choose the measure. Under the Warm Homes: Local Grant, the council's survey decides what goes in. You might be offered loft insulation and controls instead of panels. That's the scheme working as designed, not a rejection.

Scotland's main grant doesn't fund standard solar panels. The current Home Energy Scotland Grant and Loan (opens in a new tab) table lists hybrid solar PV-T systems (a loan of up to £5,000, no grant), not ordinary solar panels. Scottish homeowners wanting standard panels should look at the Warm Homes Loan Scheme.

Northern Ireland misses out on export payments. The SEG covers Great Britain only, per Ofgem. Northern Ireland homeowners can use the Warm Homes Loan Scheme and 0% VAT, but should ask their supplier directly about any export tariff.

Free Solar Panel Scams: How to Check an Offer

"Free solar" is one of the most common cold-call pitches, and the official guidance comes down to 6 rules:

• Councils, not cold callers, deliver England's free solar. The Warm Homes: Local Grant is applied for through GOV.UK and run by your council. Check your local council's website (opens in a new tab) yourself rather than trusting a caller who says they work for it.
• MCS doesn't cold call. MCS's scam guidance (opens in a new tab) says it never shares your details with installers or asks them to contact you, and won't sell warranties. In 2025 it warned about texts showing "MCS" as the sender and claiming a solar warranty had expired. Ofcom's advice is to forward spam texts to 7726.
• Watch for "maintenance" and "safety" upsells. MCS says scammers offer free checks, system upgrades, extended warranties and claims that parts need replacing. If you already have panels, contact your original installer.
• Check the installer. Use the MCS installer search (opens in a new tab). A Warm Homes loan, ECO4 and the SEG all depend on MCS certified installation.
• Don't give personal or bank details to an unexpected caller. Citizens Advice (opens in a new tab) says scammers pretend to be from energy companies or government departments, and not to use contact details or links they send.
• Report it. MCS points people to the Citizens Advice Consumer Service on 0808 223 1133. For fraud involving a Warm Homes loan, GOV.UK lists WHLScounterfraud@energysecurity.gov.uk.

A common mistake is signing on the doorstep because an offer "ends today". MCS says not to sign up on the spot. No government solar scheme closes at the end of a sales visit.

How to Get Solar Support in 2026: Steps by Situation

Here's the order to check things in, based on the official pages. None of these steps costs anything.

1. Check your EPC rating on the GOV.UK energy certificate register (opens in a new tab). D to G opens the low-income routes.
2. On a low income in England? Apply for the Warm Homes: Local Grant through GOV.UK. In Wales, call Nest on 0808 808 2244.
3. On benefits and want to try ECO4? Contact your council or an energy supplier now; anything installed must be finished by 31 December 2026.
4. Paying yourself? Get 2 or 3 quotes from MCS certified installers. Confirm each quote shows 0% VAT if it's installed before 31 March 2027.
5. Need to spread the cost? Compare Warm Homes loans with each lender's total amount repayable. A heat pump grant can be combined with a loan; see our Boiler Upgrade Scheme guide.
6. After installation, keep your MCS certificate and apply to a Smart Export Guarantee supplier.
