What actually pays for solar panels where you live, what does not, and two deadlines most guides have not noticed. Nobody is going to ring you. It is just the numbers.
Both are real dates in current legislation. If the guide you were just reading mentions neither, check when it was last updated. A surprising number were written in 2025 and never touched again.
This is the one that actually buys panels, and it is England only. You apply through your council, not through a company that rang you. Up to £16,600 towards making the house more efficient, and the same again towards low carbon heating. You can qualify three ways: household income under £36,000, or living in one of the most deprived postcodes with no income check at all, or being on certain means-tested benefits. Your EPC needs to be D to G. Owner-occupiers and private renters both count. Solar goes on where a survey says the roof suits it, which is the right answer even when it is not the one you were hoping for. One thing to watch: plenty of guides still say the cap is £15,000. It went up in July 2026.
This is the scheme behind most of the free solar panels advertising, and the ads leave out the important half. ECO4 can pay for panels, but only alongside a heat pump or certain electric heating fitted in the same job. There is no route where panels turn up on their own. The rules never actually use the word solar, which is partly why so many websites get it wrong and partly why the ads get away with it. You need to be on means-tested benefits, or referred by your council, with an EPC of D to G.
Solar PV funded only as part of a heating measure, where the home has or is getting a heat pump or qualifying electric heating in the same project

That is the gap between the scheme and the marketing. Panels ride along with a heating measure, or they do not come at all. Nobody putting a leaflet through your door is going to lead with that. If you arrived here from a free solar advert, the free solar page goes through what those adverts usually mean.
If you live in Scotland, there is no grant and no loan for solar panels or batteries. That is the honest answer and it is not the one most websites give you. It was withdrawn in 2024. Sites still advertising a £6,000 interest-free solar loan for Scotland are quoting something that has not existed for over two years. The one thing still funded is hybrid solar thermal, at £5,000 on an interest-free loan.

Wales runs its own scheme, Nest, and solar panels are on its list of possible improvements. You need to own your home or rent privately, and either be on a means-tested benefit or under the low-income thresholds. Your EPC has to be band E or lower, or band D or lower if someone in the house has a qualifying health condition. Batteries are not named on the official pages, so do not count on one.

Northern Ireland has no homeowner support for generating your own electricity. The zero VAT rate applies here as it does everywhere else, and that is the whole list.
Right now you pay no VAT at all on a solar installation, or on a battery, anywhere in the UK. That includes adding a battery to panels you already have. It ends on 31 March 2027 and goes to 5% the next day. On a typical install that is a few hundred pounds of difference for the sake of timing.
Mean installed cost per kW on existing homes, from the government's own record of certified installations rather than from anyone hoping to sell you one. New builds are left out, because a developer's price is not yours. Panels, fitting and grid connection. No battery.
| System size | Typical cost, existing homes | Rate used | Cost band |
|---|---|---|---|
| 3 kW | £6,326 | £2,108.65/kW | 0 to 4 kW |
| 4 kW | £8,435 | £2,108.65/kW | 0 to 4 kW |
| 5 kW | £8,257 | £1,651.40/kW | 4 to 10 kW |
| 6 kW | £9,908 | £1,651.40/kW | 4 to 10 kW |
Those four totals are our arithmetic from the DESNZ retrofit mean for existing homes, not published figures. Two things to read before you use them. The 5 kW total sits below the 4 kW one, and that is not a typo: the government's bands carry different rates, the bigger band is cheaper per kW, and five times the lower rate comes to less than four times the higher. It is the bands, not the market, which is why the rate sits beside each total. And the government publishes its bands as 0 to 4 kW and 4 to 10 kW without saying which side a system of exactly 4 kW falls on. We have put it in the smaller band. Treat that row as the top of the small-system range rather than a quote.

The full cost page has the battery figures, the regional pattern and why the three official numbers differ.
This one gets listed as a solar grant constantly. It is not. It pays for heat pumps and biomass boilers replacing fossil fuel heating, in England and Wales. Not a penny of it goes towards panels.
Closed in March 2026, and it only ever paid for insulation. If a page is still offering it to you, that page has not been touched in months.

The third is the Scottish loan above. Withdrawn in 2024, still advertised today.
There is no replacement coming from energy suppliers. From 2027 the government plans to fold the Warm Homes Local Grant into one larger scheme for low-income households, and solar panels and batteries are both named in it. What it will be called, who will qualify and when it opens have not been published. When they are, this page will say so. Anyone telling you the rules of a scheme that does not exist yet is guessing.
No successor supplier obligation. A single low-income capital scheme from 2027/28, not yet named
