Search for "free solar panels UK" and you'll find plenty of adverts promising government money that doesn't exist. Here's the honest picture: there is no universal solar panel grant for UK homeowners in 2026. But there are several real schemes that cut the cost — some worth thousands of pounds — and one that pays you for decades after installation. This guide covers what's genuinely available, who qualifies, and what to avoid.
| Scheme | What you get | Who qualifies | |
|---|---|---|---|
| 0% VAT | No VAT on solar & battery installations — typically £1,000+ off | Everyone, automatically, until 31 March 2027 | Universal |
| Smart Export Guarantee | ~12–15p/kWh paid for exported electricity, ongoing | Anyone with an MCS-certified installation and smart meter | Universal |
| ECO4 | Free or heavily subsidised upgrades, can include solar | Low-income households (broadly under £31,000/year) or on qualifying benefits | |
| Warm Homes Local Grant | Council-delivered upgrades, rolling out from 2026 | Low-income households in participating council areas (England) | |
| Nest (Wales) | Free improvements, can include solar | Low-income Welsh households in homes rated EPC E or worse | |
| Solar Together | Group-buying discounts, often well below typical market prices | Residents of participating council areas |
Indicative summary as of July 2026. Eligibility rules and scheme availability change — confirm with the official scheme operator before making decisions.
The biggest saving available to all households is the zero rate of VAT on solar panel and battery storage installations, which runs until 31 March 2027 before reverting to 5%. You don't apply for anything — it's simply not added to your quote. On a typical 4 kWp system costing £5,500–£8,000 installed, that's roughly £275–£400 you're not paying versus the 5% rate, and considerably more versus full VAT. If you're also adding storage, see our guide to solar battery costs — batteries qualify for the zero rate too, even when installed on their own.
The SEG pays you for every unit of electricity you export to the grid, typically 12–15p/kWh from major suppliers in mid-2026. A typical household exporting 1,700 kWh a year at 15p earns around £255 annually — on top of what you save by not buying electricity at the current price cap rate of about 26.1p/kWh (July–September 2026). Over 25 years, that beats any one-off grant. Rates vary widely between suppliers, so compare the best SEG rates before you commit.
ECO4 obliges energy suppliers to fund efficiency upgrades for low-income homes, and it runs until December 2026. Broadly, you may qualify if your household income is under £31,000 or someone receives a means-tested benefit. Be aware it's an insulation-and-heating scheme first: solar panels usually only feature when a home is moving to electric heating. It applies in England, Scotland and Wales.
In Scotland, the popular Home Energy Scotland solar loan was withdrawn in June 2024 and hasn't returned as of July 2026 — despite what some older articles claim. Scottish households still get 0% VAT, SEG payments and ECO4, and panels perform better north of the border than many expect — see are solar panels worth it in Scotland? In Wales, the Nest scheme provides free improvements, which can include solar, to low-income households in energy-inefficient homes (EPC E or worse).
The government's £5 billion Warm Homes Plan is expected to offer low or zero-interest loans for solar panels, batteries and heat pumps, with full details due later in 2026. The Warm Homes Local Grant, delivered through councils in England, is also rolling out from 2026 as a successor to earlier low-income schemes. If you don't qualify for anything today, this is the one to watch.
If a company cold-calls offering free panels with no eligibility checks, be cautious. Legitimate schemes are means-tested or council-run, and none require an upfront "survey fee". The reliable route for most households is simple: get several quotes from MCS-certified installers, claim the 0% VAT automatically, and sign up to a competitive SEG tariff. All figures here are estimates, not guarantees — your savings depend on your roof, usage and tariff.
Compare installation quotes from up to 4 MCS-certified installers — free, no obligation. 0% VAT until March 2027.
