There is no grant that pays every UK homeowner towards solar panels in 2026. What exists is targeted: the Warm Homes Plan is starting to fund fully free solar and battery installations for low-income households, ECO4 can include solar in narrow cases until 31 December 2026, and Nest in Wales installs free panels for eligible homes. If you are not in one of those groups, your support is the 0% VAT rate on installation until 31 March 2027 and Smart Export Guarantee payments for the electricity you sell back. That combination still stacks up, it is just not a grant.
Solar funding in 2026: the whole picture in one table
Five schemes get mentioned in the same breath as "solar grants UK", and only some of them will ever pay for your panels. Here is where each one stands as of July 2026.
| Scheme | Who it helps | Solar panels? | Status (July 2026) |
|---|---|---|---|
| Warm Homes Plan | Low-income households; loans for everyone else | Yes, fully funded solar and battery for eligible homes | Rolling out in phases; eligibility detail due later in 2026 |
| ECO4 | Benefits-linked, fuel-poor households (Great Britain) | Only in narrow cases tied to electric heating | Runs until 31 December 2026 |
| Nest (Wales) | Eligible lower-income households in Wales | Yes, free improvements can include solar panels | Open |
| Home Energy Scotland | Scottish homeowners | No. Standalone solar PV is not in the current funding table | Open, but for heat pumps and insulation, not solar PV |
| Great British Insulation Scheme | Was insulation only, never solar | No | Ended 31 March 2026 |
The rest of this page takes each scheme in turn, then covers the two things every household gets regardless of income: the VAT zero rate and export payments. If you are costing up a system first, start with our full guide to solar panel costs in the UK.
Why "you qualify for a solar grant" is usually a sales line
For most UK homeowners there is no solar grant to qualify for, so treat an installer or cold caller offering one as a red flag. The support that exists is aimed at low-income and fuel-poor households, and none of it is something a salesperson can sign you up to on your doorstep. The genuine schemes run through government delivery bodies, councils, and energy suppliers, with their own eligibility checks.
This matters because a typical 4.5kWp system costs around £6,100 to install, per the Energy Saving Trust. A fictional grant makes an overpriced quote look subsidised. If a company leads with "grant funding available", ask which scheme, who administers it, and where you can read the eligibility rules. Our guide to choosing a solar installer covers the other red flags.
Warm Homes Plan: fully funded solar for low-income homes
The Warm Homes Plan is the big one: £15 billion of public investment to upgrade up to 5 million homes, including fully funded solar and battery installations for low-income households. The government's January 2026 announcement said eligible families "could receive fully funded installations of solar panels and a battery, to the full average cost (currently £9,000-£12,000)", backed by £5 billion for low-income schemes. Source: gov.uk, Warm Homes Plan.
Two honest caveats before you plan around it:
- It is rolling out in phases, and you cannot simply apply today. Low-income funding is being delivered first through the Warm Homes: Social Housing Fund and the Warm Homes: Local Grant, which run through social landlords and local councils. The government says it "will set out further details of the scheme's eligibility later this year". If you rent from a social landlord or think you may qualify, your landlord or council is the place to ask.
- The free installs are for low-income households. For everyone else, the plan commits up to £1.7 billion to low- and zero-interest consumer loans covering solar panels, batteries and heat pumps. That reduces the cost of borrowing, not the price of the system. Detail on accessing the loans is also still to come.
So in July 2026 the Warm Homes Plan is real, funded, and worth watching, but for most people it is not yet a route to cheaper panels. If you were waiting for it before getting quotes, the maths of buying without a grant may surprise you anyway; see whether solar panels are worth it in the UK.
ECO4: benefits-linked help, and solar only in narrow cases
ECO4 can fund energy improvements if you receive certain benefits and your home is inefficient, but it is built around insulation and heating, not solar. The Energy Company Obligation requires larger energy suppliers to improve the homes of low-income, fuel-poor and vulnerable households across Great Britain. Following a nine-month extension, it runs until 31 December 2026. Source: Ofgem, Energy Company Obligation.
On eligibility, the government's guidance points to qualifying benefits including Universal Credit, Pension Credit, Income Support, income-based JSA, income-related ESA, Child Benefit and Housing Benefit, combined with a home rated EPC D to G if you own it, or E to G if you rent. Source: gov.uk, Energy Company Obligation.
Where does solar fit? Ofgem's ECO4 delivery guidance lists solar PV as an eligible heating measure only in specific circumstances tied to the property's heating system, broadly homes heated by electricity rather than gas. Your supplier decides which measures suit the property after a retrofit assessment, so nobody can promise you panels under ECO4 up front. If you qualify, apply through a participating energy supplier or your council, and treat any solar as a possible part of the package rather than the point of it.
You may still see the Great British Insulation Scheme mentioned on older pages. It closed on 31 March 2026, and it only ever funded insulation measures, never solar panels. Any current article offering "GBIS solar funding" is wrong twice over.
Scotland: no Home Energy Scotland funding for standalone solar PV
If you own a home in Scotland, Home Energy Scotland does not currently fund standalone solar panels. The current Home Energy Scotland Grant and Loan funding table includes solar thermal and hybrid solar PV-T systems, each with a £5,000 interest-free loan and no grant, and a footnote confirming that only PV-T systems qualify on the hybrid row. A standard solar PV system is not in the table at all. Source: Home Energy Scotland.
The scheme is generous elsewhere: heat pumps attract a £7,500 grant plus an optional £7,500 interest-free loan, with a £1,500 uplift for rural and island homes. But for a straightforward solar install, a Scottish homeowner is in the same position as one in England: 0% VAT until 31 March 2027 and Smart Export Guarantee income, which does apply in Scotland. Check current export rates in our SEG rates comparison.
Wales: Nest can install free solar panels for eligible households
Wales is the one nation where an open scheme explicitly lists free solar panels today. Nest, the Welsh Government's home energy scheme, provides free advice and, for eligible households, free home energy efficiency improvements that can include solar panels, heat pumps and insulation. Eligibility is aimed at lower-income households, and the advice service will also check whether you are entitled to benefits you are not claiming. You can reach Nest free on 0808 808 2244.

Northern Ireland: the GB schemes do not apply
None of the schemes above covers Northern Ireland, and neither does the Smart Export Guarantee. The SEG only applies in Great Britain, ECO4 is a Great Britain scheme, and the Boiler Upgrade Scheme covers England and Wales only (and is for heat pumps, not solar, in any case). NI has its own support arrangements, so if you are installing solar in Northern Ireland, ask your electricity supplier what it pays for exported units and check current NI schemes before budgeting. The 0% VAT rate on energy-saving materials does apply UK-wide, including Northern Ireland.
What every household gets: 0% VAT and export payments
No grant does not mean no help. Two things cut the real cost of solar for every UK household, whatever your income.
0% VAT until 31 March 2027. The installation of energy-saving materials, including solar panels and batteries, is zero-rated for VAT. HMRC's guidance is explicit: the zero rate runs to 31 March 2027, and from 1 April 2027 it reverts to the reduced rate of 5%, not 20%. Batteries were added to the zero rate from 1 February 2024, so a battery fitted with your panels, or retrofitted later, gets the same treatment. On a £6,100 system, the zero rate is worth several hundred pounds against the post-2027 position. Source: gov.uk, VAT Notice 708/6.
Smart Export Guarantee payments. Once your panels are generating, suppliers pay you for every unit you export to the grid. Rates are set by each supplier, not the government, and they range widely; the Energy Saving Trust puts the typical rate around 12p per unit, while the best tariffs in mid-July 2026 paid up to 18p with conditions attached. You will need an MCS-certified installation to register, which is why installer choice matters. Current rates and the small print are in our Smart Export Guarantee comparison.
Put together, the honest 2026 position is this: a typical system costs around £6,100 with VAT at zero, pays back in roughly 9 to 12 years with export payments per the Energy Saving Trust, and no grant is coming for most working households before the Warm Homes Plan loans arrive. The way to protect the maths is not grant-hunting, it is paying a fair price for a well-specified system.
