Solar panel grants and funding in 2026: what actually exists, and what is a sales pitch
Search for solar grants and you will find a wall of lead-generation sites implying free panels for everyone. The truth in 2026 is simpler and still genuinely good: there is no blanket grant, but the zero VAT rate, a government-backed loan of up to £15,000 for solar, export payments on everything you do not use, and targeted support for lower-income households add up to the friendliest funding picture solar has had in a decade.

Funding for solar in 2026 comes in four honest flavours: a tax break everyone gets, a government-backed loan most owner-occupiers can apply for, export income everyone with an MCS-certified installation can earn, and fully funded help for a defined group of lower-income households. Everything else you see advertised is one of those four wearing a costume.
The short version
| Support | Who gets it | Worth, roughly |
|---|---|---|
0% VAT to 31 March 2027 | Every domestic supply-and-install job in Great Britain | A five-figure system priced as if VAT never existed |
Warm Homes Loan | Owner-occupiers of existing homes, some landlords | Up to £15,000 for solar PV, up to £15,000 for battery, low or zero interest |
Smart Export Guarantee | Anyone with an MCS-certified installation and a smart meter | Ongoing income on every exported kWh, tariff-dependent |
ECO and targeted schemes | Lower-income and fuel-poor households, criteria apply | Up to fully funded measures where eligible |

Why there is no blanket solar grant, and why that is fine
The Energy Saving Trust states it plainly: there are no dedicated solar panel grants from the UK Government. The economics explain why. With an average system around £7,600 and payback periods that reached roughly nine to twelve years across the UK on the Trust's July 2026 figures, solar no longer needs a purchase subsidy to make sense; it needs financing and a fair export price, which is exactly what the current mix provides.
The zero rate is the grant nobody calls a grant
0% VAT on domestic solar until 31 March 2027 takes a five-figure sum and quietly removes what would otherwise be the tax on top. No forms, no eligibility test, no waiting list: we apply it at the point of quoting.
The Warm Homes Loan, the piece most adverts are actually describing
The Warm Homes Plan commits close to £15 billion to improving UK homes, and its loan scheme is the route most relevant to solar: published per-technology caps of up to £15,000 for solar PV and up to £15,000 for battery storage, with participating lenders cutting their own rate by up to 5 percentage points, for owner-occupiers and private landlords. An EV charger can ride along with a solar or battery installation. The scheme launched on 26 to 27 October 2026, and GOV.UK names ten lenders.
We keep a dedicated page on the Warm Homes Loan tracking the official Scheme Rules, dated on every claim, including how it stacks with the £7,500 Boiler Upgrade Scheme grant for households pairing solar with a heat pump.

Export income: the funding that keeps paying
The Smart Export Guarantee obliges larger suppliers to pay for every kilowatt hour you export, and over 25 years that stream routinely outearns any historical grant. The catch is that rates vary enormously between suppliers and tariff structures, and the best rates usually carry conditions. That is a decision worth twenty minutes: our guides on export rates as of August 2026 and why tariff choice moves payback more than kit choice do that arithmetic with dated sources.
Fully funded help, and who genuinely qualifies
Fully funded installations are real but targeted: ECO places obligations on suppliers to help fuel-poor and lower-income households, and the Energy Saving Trust notes the Warm Homes Plan is set to include fully funded government support to install solar for people on low incomes. Eligibility runs on benefits received, household income and the property itself. If you qualify, it is the best deal on this page; if a salesperson implies everyone qualifies, that is your cue to end the call.
One date matters here: ECO4, the current supplier-funded scheme, closes to new applications on 31 December 2026 and the government has said there is no successor supplier obligation, so this is the last scheme of its kind rather than one due to renew. What follows it is grant funding through the Warm Homes Plan, not a like-for-like replacement, so anyone who might qualify on income or benefits should check eligibility well before the closing date rather than after.
The test for any funding claim
Ask which scheme, by name, and where its rules are published. The four on this page all have official, public rules. An offer that cannot name its scheme is marketing, not funding.
How the pieces stack on a real installation
Price the system at 0% VAT
Get the supply-and-install quote first; the zero rate is already in it. This is the baseline every other support works against.
Decide financing: loan or savings
If the Warm Homes Loan is live for your area and you qualify, its caps comfortably cover a domestic solar and battery installation at low or zero interest. Compare its total cost of credit against your own savings rate rather than assuming either way.
Choose the export tariff before the kit
The spread between a weak and a strong export arrangement is worth more than most hardware upgrades. Lock the tariff decision into the design conversation, not after commissioning.
Check targeted eligibility once
If anyone in the household receives qualifying benefits, check ECO and Warm Homes Plan support before self-funding anything. Ten minutes against a published criteria list settles it.
A free remote design call prices your actual roof at the zero rate, sets the export tariff conversation up properly, and tells you honestly whether any targeted scheme fits your household. No visit, no obligation.

Are there any free solar panel schemes in the UK in 2026?
Not as a general offer. Fully funded installations exist only through targeted schemes for lower-income households, such as ECO and the support signalled under the Warm Homes Plan. Anyone advertising free panels to the general public is either describing those narrow schemes loosely or selling something else, such as a roof-rental arrangement, and the small print deserves close reading.
Is there VAT on solar panels in 2026?
No. Domestic solar installations in Great Britain attract 0% VAT until 31 March 2027, which on a typical installation is worth more than most grants ever were. The rate applies to supply-and-install packages, panels plus batteries included, rather than to kit bought separately for self-installation.
How much can I borrow under the Warm Homes Loan for solar?
The published per-technology caps allow up to £15,000 for solar PV and up to £15,000 for battery storage, with participating lenders cutting their own rate by up to 5 percentage points, for owner-occupiers and private landlords. The scheme launched on 26 to 27 October 2026 with ten lenders named on GOV.UK; our Warm Homes Loan page tracks the official rules and is dated on every claim.
Do export payments count as funding?
Functionally, yes: the Smart Export Guarantee pays for every kilowatt hour you send to the grid, and over a system's life that income is often worth more than any upfront grant. The rate you get depends on your supplier and tariff choices, which is exactly why tariff choice moves payback more than kit choice.
