Solar panel grants in the UK in 2026: what support actually exists
Searches for free solar panels run hot every year, and most of what ranks for them is a lead form in a hat. This page sets out the support that genuinely exists in 2026, who it is aimed at, and what to do if none of it applies to you.

The short answer
What support exists in September 2026
Four separate things get muddled together in search results. They are not the same, and only some of them are live.
Warm Homes: Local Grant
Available in England, delivered through local councils. It is aimed at lower-income households living in privately owned or privately rented homes with an Energy Performance Certificate rating of D, E, F or G. Funding can include solar panels alongside measures such as insulation, smart controls and air-source heat pumps.
The council arranges a survey and pays approved contractors directly for approved work. You do not receive cash, and eligibility depends on your council having funding available when you apply. Our grants and funding page covers the qualifying routes in more detail.
ECO4
The Energy Company Obligation scheme runs until 31 December 2026. It obliges larger energy suppliers to fund energy-efficiency improvements for eligible households, typically those on qualifying benefits or in low-income circumstances, in poorly performing homes. What is offered under it depends on the supplier, the assessment of your property and the measures judged appropriate for it.
Because the scheme has a fixed end date, check the official guidance and your supplier rather than assuming the version of ECO4 described on a third-party site is current.
0% VAT on qualifying solar installations
Qualifying residential solar installations currently benefit from 0% VAT through 31 March 2027. This is not a grant and no application is involved: it should already be reflected in the price a compliant installer quotes you. It is worth naming in a quote conversation, because the useful question is whether the quoted total is VAT-free under the relief, not whether VAT is added later.
Government-backed low-interest loans
Government-backed consumer loans for home-energy improvements have been announced and are expected in 2027. They are not currently available, so they cannot form part of a 2026 decision. Treat any installer or comparison site that offers to arrange one today with considerable suspicion.
Could I qualify?
A first filter, not an eligibility decision. Only your council, your supplier or the official scheme page can decide that.
- 01Is the property in England, and privately owned or privately rented? If yes, the Warm Homes: Local Grant is the first thing to check with your local council.
- 02Is the EPC rating D, E, F or G? Warm Homes: Local Grant is aimed at properties in that band. You can look up an existing certificate on the official EPC register.
- 03Is household income at the lower end, or does someone receive qualifying benefits? Both schemes are targeted at lower-income households, and benefit receipt is often the clearest route in.
- 04Is your energy supplier a larger obligated supplier? If so, ask them directly what is available under ECO4 before the scheme ends on 31 December 2026.
- 05If none of the above fits, you are self-funding, with 0% VAT applied by a compliant installer on a qualifying installation through 31 March 2027.
What if I do not qualify?
Most households do not, and that does not settle whether solar is a good idea for your roof.
Missing out on a grant changes the cost side of the calculation, not the logic of it. Solar pays when you use a decent share of what you generate, when the installed price is sane for the system you get, and when you are staying in the house long enough to see it through. The honest test is arithmetic on your own numbers rather than a headline saving from a brochure.
- Find your annual electricity use in kWh from a bill or your smart meter data, and be honest about how much of it happens in daylight.
- Put your own import price, quoted cost and export rate into the calculator rather than accepting an installer's assumed figures.
- Get more than one itemised quote, and compare like for like: panel count and wattage, inverter, scaffolding, electrical work and warranties.
- Confirm the quote reflects the 0% VAT relief on a qualifying installation rather than adding VAT at the end.
- Price any battery separately, so you can see what each part of the bundle is actually buying you.
- Check whether shifting usage into the middle of the day is realistic for your household before sizing a larger array.
Common mistakes with grant searches
- 01Treating free solar panels as a scheme name. It is a marketing phrase, not a programme, and the pages using it are usually lead-generation.
- 02Handing over contact details before checking the official eligibility criteria, which are free to read and take minutes.
- 03Assuming a grant that covers insulation or a heat pump automatically covers solar. Measures are assessed per property.
- 04Believing a scheme is still open because an article says so. ECO4 has an end date of 31 December 2026 and the VAT relief runs to 31 March 2027.
- 05Accepting a higher installed price because a grant or discount is mentioned. Compare the total you pay, not the discount claimed.
- 06Counting on the government-backed loans expected in 2027 when deciding what to sign in 2026.

Run the numbers on your own roof
Grant or no grant, the decision comes down to what you generate, what you use and what you paid. The calculator shows the workings rather than a marketing figure.
