This guide explains every active UK support scheme for solar panels in 2026, who qualifies, and what you can realistically expect to receive.
The phrase 'government grant for solar panels' still circulates widely online, but it describes a scheme that closed years ago. The Feed-in Tariff ended in 2019. There is no universal grant that pays for a new solar installation on a private home in 2026.
What does exist is a set of targeted schemes aimed at lower-income and fuel-poor households, a tax relief that benefits almost everyone, and a payment for surplus power that runs for the life of your system. Each one works differently, and eligibility varies. Knowing which scheme you might qualify for is the first practical step before talking to any installer.
Global events demonstrate there’s not a moment to waste in our drive for clean power because there can be no energy security while we are so dependent on fossil fuels.
The Energy Company Obligation (ECO4) is the main route to heavily subsidised or fully funded solar panels for eligible households. Under ECO4, large energy suppliers must fund energy-efficiency improvements for homes that meet the criteria. An ECO4 income eligibility threshold of under £31,000 applies, and households must typically receive a qualifying means-tested benefit alongside that income limit.
ECO4 does not operate as a direct payment to you. Instead, your energy supplier arranges and funds the work through an approved installer. Solar panels can be included as part of a broader package of measures, though the scheme prioritises insulation and heating improvements first. Eligibility is assessed on your household income, benefit status, and the current energy-efficiency rating of your home. Applying through your energy supplier or a council referral scheme is the standard route in.
The scheme is set to run until March 2026, so checking eligibility sooner rather than later is sensible if you think you qualify.

The Warm Homes Plan is the government's broader ambition to upgrade up to 5 million homes by 2030, according to FMB Home Picks. Within it, the Warm Homes: Local Grant is the most directly relevant scheme for homeowners. It targets owner-occupiers and private renters in lower council tax bands whose homes have a low energy-efficiency rating. The grant can cover up to £15,000 towards energy-efficiency improvements, including solar panels where they form part of a whole-house upgrade.
Delivery is through local authorities, so availability and application processes vary by area. A separate solar top-up fund of £100m has been allocated for social housing and schools, according to the same source. For private homeowners, the Local Grant is worth checking with your council, particularly if your home is poorly insulated or has an EPC rating of D or below.
The Warm Homes Plan also includes a Social Housing Decent Homes Fund targeting 100,000 rented homes, but that stream is directed at landlords and social housing providers rather than individual owner-occupiers.
Government funding allocations under the Warm Homes Plan, £bn
| New grant funding | 1.5 |
|---|---|
| Boiler Upgrade Scheme | 2.7 |
| Total plan budget | 15.0 |
The headline £15bn figure spans the whole parliament and includes existing commitments, the genuinely new money is far smaller.
The most widely available form of government support for solar is not a grant at all. Residential solar installation is charged at 0% VAT, zero-rated to 31 March 2027 under HMRC's VAT Notice 708/6. On a typical installed system cost of £5,000 to £10,000, that represents a meaningful saving compared with the standard 20% rate, without any application or eligibility check.
This relief applies automatically to any qualifying domestic installation by a VAT-registered contractor. You do not need to apply, and it covers both the panels and the installation labour. The zero rate is scheduled to end on 31 March 2027; what happens after that date has not been confirmed, so installations completed before that point lock in the current position.
For the full detail on costs, payback and the Smart Export Guarantee, the Solar Panel Cost UK hub page covers those figures with stated assumptions.
The Smart Export Guarantee (SEG) is not a grant. It is a legal obligation on larger electricity suppliers to pay you for any surplus solar power you export to the grid. Electricity suppliers with at least 150,000 domestic customers must offer an export tariff; the rate is supplier-set and must always be above zero. Your installation must be certified under MCS or an equivalent scheme to qualify.
Rates vary between suppliers, and comparing them pays. The SEG turns your system into an ongoing income stream rather than a one-off subsidy. For a detailed comparison of SEG rates and how to apply, the page on grants and funding for UK solar covers this in full.
The SEG matters for your payback calculation: according to the Energy Saving Trust, a typical payback period is 9 to 12 years on an ideal roof, and longer if east-facing or shaded. The SEG contribution is one of several factors that determine where your system lands in that range.
Most domestic rooftop solar installations fall under permitted development rights, meaning you do not need to apply for planning permission. The rules were updated under the General Permitted Development Order (GPDO), most recently for 2026, but the core position for standard pitched roofs remains the same.
Exceptions apply. If your home is a listed building, you will need listed building consent before any panels are fitted. If it sits in a conservation area, permitted development rights may be restricted or removed entirely. Ground-mounted systems and frame mounts are treated differently from rooftop arrays and are more likely to require a full planning application.
Local authorities can also withdraw permitted development rights in specific areas through an Article 4 Direction. Checking with your local planning authority before committing to an installation avoids delay, particularly if your home is in a designated area. An MCS-certified installer will flag any restrictions during the survey stage.
No grant or scheme changes the underlying physics of your roof. A south-facing pitch between 30 and 40 degrees with no shading delivers the best output. East or west-facing roofs still generate useful power but at a lower yield. A roof older than 20 years is worth inspecting before installation: replacing a roof after panels are fitted costs significantly more than doing it beforehand.
Pairing a battery with your solar panels can improve the economics if you are away during peak generation hours, on a time-of-use electricity tariff, or want resilience against grid outages. The improvement is less pronounced if you already use a high proportion of your solar output directly during the day. Panels carry a typical warranty of 20 to 25 years; inverters typically 5 to 15 years, according to the Energy Saving Trust and Which?. Factor inverter replacement into your long-term cost view.

Answers to the most common questions.
Fully funded solar panels are only available to households that qualify for ECO4 or the Warm Homes Local Grant. Both schemes have income and eligibility conditions. There is no universal free solar panel programme for all UK homeowners. The ECO4 income threshold is under £31,000, alongside a qualifying benefit requirement.
Contact your energy supplier directly and ask about ECO4 funding, or ask your local council about referral routes. An approved installer will assess your home's eligibility. The scheme runs through approved contractors, not through a central application portal, so the first step is contacting your supplier or council.
Solar panels can be included as part of a Warm Homes Local Grant package, up to £15,000 in total, but the grant is not available for solar alone. It is delivered through local authorities and targets homes with a low EPC rating. Check availability with your local council, as delivery varies by area.
No. The Smart Export Guarantee is an ongoing export payment for surplus power sent to the grid, not a one-off grant. Rates are set by individual suppliers and must be above zero. Your installation must be MCS-certified to qualify. It contributes to your payback over time rather than reducing upfront cost.
Most rooftop domestic solar installations are permitted development and do not need planning permission. Listed buildings need listed building consent. Conservation areas may have additional restrictions. Ground-mounted and frame systems are more likely to require a full planning application. Always check with your local planning authority if in doubt.
According to the Energy Saving Trust, a typical payback period is 9 to 12 years on an ideal roof, and longer for east-facing or shaded roofs. The actual figure depends on system size, your consumption pattern, the export tariff you receive under the SEG, and the total installed cost.
