Solar panel grants UK 2026: who qualifies for free or funded panels

Solar panel grants at a glance

Free solar: what is realistic?

Free solar is possible for some households, but it is not a public offer for every home. Installers and councils normally check income, benefits, EPC rating, fuel poverty risk, roof suitability, ownership or landlord consent, and whether solar makes sense alongside insulation or heating improvements.

If you receive benefits, start with free solar panels on benefits and ECO4 eligibility. If you are a homeowner but not benefit-eligible, the broader government grants for homeowners route may be more useful.

Free solar vs funded solar: who genuinely qualifies

It helps to separate two different things people mean by a "solar grant". A small number of households can get panels fully funded (free), while a much larger group can only get the cost reduced. Being honest about which group you are in saves a lot of wasted time and stops you falling for over-promising adverts.

In short: fully free solar is mainly an ECO4 or council-route outcome for eligible homes, while everyone else combines 0% VAT, SEG and competitive quotes to bring the net cost down. If you are not sure which group you fall into, the eligibility checker is the quickest way to find out.

ECO4 solar panels: the main free-solar route

ECO4 (the fourth phase of the Energy Company Obligation) is still the main route where solar PV may be installed at no upfront cost. It is funded by obligated energy suppliers rather than paid to you as cash, and it is designed to improve the least efficient homes — so solar is usually assessed as one measure within a whole-house package rather than as a standalone giveaway. The scheme has been extended and now runs to 31 December 2026; the government has confirmed there will be no "ECO5", with the publicly funded Warm Homes Plan taking over the supplier-obligation model from 2027 (GOV.UK, "Extending the ECO4 end date").

Because ECO4 is a fuel-poverty scheme, solar is only funded where it genuinely helps a qualifying household in a qualifying home. In practice, installers and Ofgem-obligated suppliers check:

• Benefits or low income: you usually qualify through a means-tested benefit (Universal Credit, Pension Credit, Income Support, income-based JSA/ESA, Working/Child Tax Credit, Housing Benefit) — or through LA Flex if you do not receive those benefits (see below).
• EPC rating: the home normally needs to be inefficient enough (typically EPC band D–G) for funded measures to make sense, and solar is often paired with insulation to lift the rating.
• Property and tenure: tenants need landlord permission; landlords should also read energy grants for landlords.
• Survey approval: final approval depends on a survey, the measure mix, funding availability and each installer's criteria — so an initial "you qualify" is not the same as an approved install.

If your household receives benefits, start with the ECO4 eligibility rules and the free solar panels on benefits guide, then use the eligibility checker to see whether a solar package is realistic for your postcode and property.

LA Flex: the route if you are not on benefits

LA Flex (Local Authority Flexible Eligibility) lets your council widen ECO4 eligibility to households that do not receive standard qualifying benefits but are still on a low income, vulnerable to cold, or living in fuel poverty. Each council publishes a "Statement of Intent" setting its own criteria — for example an income cap, a health condition made worse by a cold home, or living in a priority postcode. If you are a homeowner just above the benefits threshold, LA Flex is often the difference between qualifying and not. See our dedicated LA Flex scheme guide for how to be referred, and check your own council's Statement of Intent.

Warm Homes and council support

The Warm Homes Plan and local delivery schemes can affect which measures councils and installers prioritise. Some areas may support solar, while others focus first on insulation, heating or whole-house upgrades.

Because local rules vary, check your council, LA Flex statement of intent and low-income grant routes before assuming solar is excluded. A council-backed path may be stronger if you are not on standard ECO4 benefits but still face high energy costs.

Warm Homes: Local Grant — the post-GBIS council route

Since the Great British Insulation Scheme closed to new applications on 31 March 2026, the Warm Homes: Local Grant has become one of the main council-delivered routes for lower-income households in England. It launched in April 2025 and is funded to run until March 2028, so it outlasts ECO4. Local authorities deliver it and set some of their own detail, but the core eligibility is broadly:

• Your home is in England with an EPC rating of D, E, F or G.
• Your household income is usually £36,000 a year or less, or you live in one of the most deprived areas (income deciles 1–2), or you receive a means-tested benefit.
• GOV.UK lists the covered improvements as wall, loft and underfloor insulation, air source heat pumps, smart heating controls and solar panels — so solar is explicitly in scope, though your council and surveyor decide the final measure mix for your home.
• You must own the home (or rent from a private landlord who consents); social-housing tenants are covered by separate funding.

If you are not on standard ECO4 benefits but still have a low income and a colder home, this is often the strongest route to check. Apply via the GOV.UK "Apply for the Warm Homes: Local Grant" service, which routes you to your local council. Scotland, Wales and Northern Ireland run their own separate schemes.

0% VAT on solar panels UK 2026

VAT relief is not a grant paid into your bank account. It reduces the installed cost because qualifying domestic solar panels and battery storage can be charged at 0% VAT during the relief period. In Great Britain this zero rate currently runs until 31 March 2027, after which the rate is due to return to the reduced 5% band — so the saving is worth locking in while it lasts.

Private buyers should ask every installer quote to show the VAT treatment clearly. If you are comparing paid solar options, use the full solar panel costs guide alongside this page.

Solar incentives UK 2026: what counts?

When people search for solar incentives, they usually mean a mix of upfront grants, tax relief, export income and cheaper group-buying routes. ECO4 and LA Flex can reduce or remove upfront costs for qualifying homes, while 0% VAT and SEG are available on a broader paid-install route when the installation meets the rules.

Smart Export Guarantee

The Smart Export Guarantee pays eligible households for surplus solar electricity exported to the grid. It does not reduce the upfront installation price, but it can improve lifetime payback.

• You usually need an MCS-certified installation or equivalent evidence accepted by the supplier.
• You need export metering, usually through a suitable smart meter.
• Rates vary by supplier, so compare tariffs once your system is installed.

Smart Export Guarantee rates in 2026

SEG rates are set by each licensed supplier and are not capped by Ofgem, so they vary widely and change often. Ofgem only requires larger suppliers to offer a SEG tariff above zero — it does not set the price. As a rough guide to the 2026 market:

To claim SEG you normally need an MCS-certified installation (or Flexi-Orb equivalent) and a smart or export meter. Because rates can change on roughly a month's notice, treat every figure here as indicative and compare live tariffs when your system is installed — a strong export tariff can be worth several hundred pounds a year. Ofgem sets the framework but not the price; see its Smart Export Guarantee guidance for the rules.

Solar panel grants in Scotland, Wales and Northern Ireland

Energy support is not identical across the UK. ECO4 and 0% VAT apply UK-wide, but the Warm Homes: Local Grant is England-only, and Scotland, Wales and Northern Ireland run their own devolved schemes with different names, budgets and rules. This is one of the most misunderstood parts of solar funding, so it is worth being precise.

Scotland: Home Energy Scotland and Warmer Homes Scotland

There are two main non-ECO routes in Scotland, and it is important to know that Home Energy Scotland does not fund standard standalone solar panels:

• Home Energy Scotland Grant and Loan — this is aimed mainly at heating. A heat pump can attract a grant of up to £7,500 (with a £1,500 rural uplift) plus an optional interest-free loan of up to £7,500. Standard solar PV is not a fundable measure on its own; only hybrid solar PV / water-heating (PV-T) systems qualify, via an interest-free loan of up to £5,000 with no grant (Home Energy Scotland).
• Warmer Homes Scotland — the Scottish Government's fuel-poverty scheme, which can install measures (potentially including solar) free for eligible low-income and vulnerable households.
• ECO4 — the UK-wide route above also operates in Scotland and is usually the strongest path to fully funded solar for benefit or LA Flex households.

So in Scotland, "free solar" generally means an ECO4 or Warmer Homes Scotland outcome, while Home Energy Scotland is a low-cost loan route for heating-led upgrades. See our energy grants in Scotland guide for the current detail, and treat all amounts as indicative — devolved figures change often.

Wales: the Nest (Warm Homes) programme

In Wales the main route is the Welsh Government Warm Homes Nest scheme, which can provide free home energy improvements — including insulation, heating and, where suitable, solar panels — to eligible homeowners and private tenants. Broadly, your home needs an EPC rating of E (54) or below (or D/68 or below if someone has an eligible cold-related health condition), and you must meet an income or means-tested benefit test. A Nest adviser checks eligibility, then arranges a survey and a tailored package installed at no cost. Free energy advice is available to everyone in Wales on 0808 808 2244 (GOV.WALES, Nest).

Northern Ireland

Northern Ireland is outside ECO4 and runs its own support, such as the NI Sustainable Energy Programme (NISEP) and the Affordable Warmth scheme through local councils and the Housing Executive. Solar is less commonly funded than insulation or heating, so check the current NI schemes and your local council before assuming a solar grant is available.

Solar Together and group buying

Solar Together is a council-backed group-buying model, run by the specialist organisation iChoosr in partnership with local and county councils across much of England (including most London boroughs, Greater Manchester, the West Midlands, and counties such as Essex, Suffolk, Surrey, Kent, Hampshire, Devon and Cornwall). It uses collective bargaining to secure a lower installed price — not a free solar grant. It works in a few steps:

• Register free during an open round, with no obligation, giving basic details about your roof and electricity use.
• Installers bid in a reverse auction to supply the whole registered group, which drives the price down.
• You get a personal recommendation and can accept or walk away. Councils and the Greater London Authority have reported savings of roughly 20–30% versus buying alone.

Treat it as one strong comparison point rather than the only quote you get. You should still compare product quality, panel and inverter warranties, battery options, installer accreditations (MCS) and the full paid-cost breakdown against normal market quotes — see solar panel costs for the private-pay benchmark.

Ended schemes to ignore

The Feed-in Tariff is closed to new applicants, and the Green Homes Grant voucher scheme has ended. Be cautious with any advert implying those schemes are still open for new solar applications.

Myths and scams

• "Everyone can get free solar" is false. Eligibility is restricted and survey-led.
• "SEG is a government grant" is misleading. It is an export tariff paid by suppliers.
• "You must sign today" is a red flag. Take time to compare quotes and check accreditations.
• "No survey needed" is risky. Roof condition, shading and electrical setup matter.

Solar panel grants by region

The national schemes above apply UK-wide (or England-wide for the Warm Homes: Local Grant), but what is actually available locally depends on your council — its LA Flex criteria, whether it is running a Solar Together round, and any area-based programmes. Uptake also tends to be higher where there is older, less-efficient housing stock.

Check the routes framed for your area on our local guides — for example London, Birmingham, Manchester, Bristol, Leeds, Cornwall, Glasgow and Edinburgh — or search your own council's household support and Statement of Intent pages. Scottish and Welsh households should also check energy grants in Scotland and Welsh Government routes, which differ from England.

Which route should you take?

Paid solar costs in 2026

Costs vary by roof access, scaffolding, inverter choice, battery size, monitoring, warranties and local labour. Treat any quote that is far below market as something to verify carefully. For the full private-pay picture — payback periods, battery economics and financing — see the dedicated solar panel costs guide; this page focuses on the funding routes that reduce that bill.

Grants vs paying yourself: the net cost

It helps to see how the routes stack up on the same system. Take a typical 4 kWp install:

• If you qualify for ECO4 or a council route: the solar element can be fully funded, so your out-of-pocket cost is £0 for the panels, though the scheme decides the specification.
• If you pay privately: you already benefit from 0% VAT (worth roughly £1,200–£1,600 on a £6,000–£8,000 job versus the old 5% rate), you can shave a further ~20–30% through a Solar Together round, and then SEG export income plus bill savings pay the rest back over time.

In other words, most households do not get free panels — they get a paid install that is heavily de-risked by tax relief, group buying and export income. The eligibility checker tells you which side of that line you are on.

Next steps

1. Use the eligibility checker if you may qualify for ECO4, LA Flex or low-income support.
2. Read free solar panels on benefits if your household receives benefits.
3. Compare the full paid route in solar panel costs if you are funding the installation yourself.
4. Check local routes: council support, Solar Together, Scotland or Wales-specific schemes.
5. Only proceed after a proper survey, written quote, warranty review and MCS/installer checks.
