Solar panel grants in Wales: what exists in 2026
Searches for solar panel grants in Wales mostly turn up pages written for England, or adverts. Here is what actually applies to a Welsh home, scheme by scheme, and what doesn't.
In brief
There is no general solar grant in Wales. Warm Homes Nest, run by the Welsh Government, can include rooftop solar for eligible low-income owners and private tenants. Warm Homes: Local Grant is England only. Everyone can use 0% VAT on installed solar until 31 March 2027 and export payments; owner-occupiers can borrow through the Warm Homes Loan Scheme.

How Wales does it
One national scheme, not 22 council ones
In England, public money for solar on lower-income homes flows mainly through councils, under Warm Homes: Local Grant. Wales does it differently. Home energy support for households in fuel poverty is run nationally by the Welsh Government through Warm Homes Nest, which launched in its current form following the 2023 Warm Homes Policy Statement. The same scheme, with the same rules, covers Anglesey and Monmouthshire alike.
That has two consequences for anyone searching from North Wales. First, the English route simply isn't available: GOV.UK's Local Grant pages are for England. Second, the place to start is Nest itself, rather than your council. Councils in Wales may run or refer to other help, but the scheme that can put solar on a lower-income home is Nest.
Nest is described by the Welsh Government as demand-led: households apply or are referred, and eligible homes get a package designed for that property.

The grant route
What Nest's figures say about solar
The Welsh Government's first annual report on the new Nest scheme covers its opening months. Between October 2024 and March 2025, Nest installed improvement packages in 348 households. Packages are designed for each property, so there's no standard set of measures; the report lists boilers, central heating, insulation, solar panels and heat pumps among them. Solar and other renewable energy measures made up 26% of installations, heating systems around 31%, and air source heat pumps with their hot water cylinders about 2%.
Nest also has a per-household threshold: projects above £35,000 need additional assurance and sign-off before going ahead. Average spend varies by area; the report gives Gwynedd's average as £6,100 per home, the lowest in Wales, and the Vale of Glamorgan's as £19,700. The six North Wales areas are set side by side on our council areas page.
In other words, solar is a real and regular part of what Nest fits, but it's the Nest team's decision, made for each home. See Warm Homes Nest and who Nest is for.
Everyone else
If you're not eligible for Nest
Most households in Wales won't meet Nest's routes, which require a means-tested benefit or a qualifying health condition with a low income, and a low EPC rating. For them, solar is paid for privately, with three things that genuinely help.
- 0% VAT on solar installed in a home until 31 March 2027, then 5%.
- The Warm Homes Loan Scheme, borrowing for owner-occupied homes through participating lenders, repaid in full.
- Export payments under the SEG for electricity sent to the grid from a certified, metered system.
See export payments and VAT and the loan scheme.
Dates
What changes soon
ECO4, the supplier-funded scheme that has paid for some low-income home improvements across Great Britain, ends on 31 December 2026, and the government has said there will be no successor obligation on suppliers. The 0% VAT rate on installed solar, batteries and heat pumps becomes 5% on 1 April 2027. And the higher £9,000 Boiler Upgrade Scheme amount for off-gas homes replacing oil or LPG runs until March 2027 (see oil and LPG homes).
None of these is a reason to rush. They are reasons to check which rules apply on the date work is invoiced, and to be wary of offers built around a closing scheme. See the timeline to 2028 and ECO4 in Wales.
The claims
Offers that claim Welsh Government backing
If an advert or caller offers solar paid for by the Welsh Government to any homeowner, it is misdescribing something. It may be a loan, a roof-rental arrangement, a closing ECO4 offer, or a lead-generation form. The genuine Welsh scheme is Nest, it is means-tested, and you can contact it yourself. Since April 2025, falsely claiming approval by a public body has been banned outright under consumer law. See spotting fake offers.
Solar grant questions in Wales
Is there a government grant for solar panels in Wales?
Not a general one. The Welsh Government’s Warm Homes Nest scheme can include rooftop solar in improvement packages for eligible low-income owners and private tenants. Households that can pay have no solar grant.
Why do I keep reading about council solar grants?
Those are usually about Warm Homes: Local Grant, which English councils run. It doesn’t apply in Wales.
How much solar did Nest fit?
The Welsh Government reports that solar and other renewable measures made up 26% of installations between October 2024 and March 2025, across 348 households that received improvement packages in that period.
Is the Boiler Upgrade Scheme a solar grant?
No. It applies in Wales but pays only towards heat pumps and biomass boilers.
Border areas
Living near England
Flintshire and Wrexham sit on the border, and many households there see English news, English adverts and English council websites. That makes it easy to read about a council solar grant and assume it applies. Warm Homes: Local Grant is run by English councils for homes in England; a Welsh address is outside it, however close to Chester or Shrewsbury.
The same goes the other way for the English planning changes of August 2026 for flats, balconies and plug-in solar: they apply in England only. Welsh homes follow Welsh rules.
Putting it together
A sensible order of checks
First, check whether your household might meet one of Nest’s routes. If so, contact Nest before anything else, because a package costs eligible households nothing.
If not, decide whether solar suits your home on its own merits: get an MCS installer’s survey and written estimate, and compare quotes. Then use the reliefs that apply to everyone, and the loan scheme if you own your home and need to borrow. If a heat pump is also on your mind, the Boiler Upgrade Scheme applies in Wales.
