“Is there a grant for solar panels?” is one of the most common questions we get, and the honest answer disappoints a lot of people: for most households, there is no government grant that pays for solar panels.
That is not the whole story though. Two national schemes still cut the cost or pay you back over time, and one route does fund solar outright for households that qualify. Here is what is real in 2026, so you can stop chasing something that does not exist and work with what does.
The short version
| What | Who it helps | What it does |
|---|---|---|
| ECO4 | Households on qualifying benefits with a poor EPC | Can fund solar outright, alongside insulation and heating |
| 0% VAT | Everyone | Removes VAT from the install, until 31 March 2027 |
| Smart Export Guarantee | Anyone with an MCS-certified system | Pays you for the electricity you export |
There is no fourth scheme waiting behind those. If you have seen a “UK solar programme” or a “government solar grant” advertised as free panels for all, treat it with suspicion.
ECO4: the one route that can actually fund solar
ECO4 is the scheme that pays for energy efficiency work in full for qualifying households. It is funded by the large energy suppliers rather than paid out as cash, and the work is delivered by approved installers.
Solar is not the main focus. ECO4 leads with insulation and heating, because those usually do more for a cold, expensive home than panels do. But solar PV can be included where a property assessment supports it.
Who qualifies. Broadly, you need to be receiving certain means-tested benefits and live in a property with a poor EPC rating. Some councils also run flexible eligibility routes for households that are not on benefits but are still struggling with energy costs, so it is worth asking even if you think you fall outside the rules.
The timing matters now. ECO4 closes on 31 December 2026, with the Warm Homes Plan taking over from January 2027. If you might qualify, apply in 2026 rather than waiting to see what replaces it. The detail of the new scheme is not settled, and there is no guarantee the same measures will be covered on the same terms.
0% VAT: the discount almost nobody notices
Since April 2022 the government has charged zero VAT on energy-saving materials and their installation. Solar panels and battery storage both qualify, as do heat pumps and most insulation.
You will not see this as a line on a form, because it is already baked into the price your installer quotes. On a typical home solar and battery system it is worth a four-figure saving.
It ends on 31 March 2027, after which the previous 5% reduced rate is expected to return. If you are paying for solar yourself, having the work done before that date keeps the saving.
Smart Export Guarantee: money back, slowly
The Smart Export Guarantee (SEG) is not a grant. It is a requirement on larger electricity suppliers to pay you for surplus electricity your panels send back to the grid.
Every licensed supplier with 150,000 or more customers has to offer an SEG tariff, and you can choose any of them. It does not have to be the supplier you buy electricity from.
Two things people get caught out by:
- Your system has to be installed by an MCS-certified installer and registered at handover. A cheap install outside that framework locks you out of SEG permanently.
- You need an export-capable smart meter and an export MPAN from your local network operator. In some rural postcodes the smart meter rollout still lags, and not every meter type is accepted.
Check with your chosen supplier that they can actually register your address before you build your sums around a headline export rate. Treat the money you save on your own bills as the main return, and export payments as the second layer.
If you do not qualify for ECO4
This is where most people land, and it is worth being straight about it. If you are not on qualifying benefits, the realistic position is that you pay for solar, with the VAT removed and export payments coming back over time.
That still works for a lot of households, but it depends entirely on your roof, your usage pattern, and whether a battery makes sense alongside the panels. The only way to know is a proper quote against your own property rather than an average.
Our sister company UKEM Group installs solar and battery systems across mainland Britain and publishes what a solar and battery system involves and costs, including how the export side works once the system is running. If you want a figure for your own home rather than a national average, that is the place to start.
What to check before you commit to anything
- Be wary of “free solar panels” adverts. Outside ECO4, free solar in the UK usually means a rent-a-roof arrangement where somebody else owns the panels and keeps the income. Read what you are signing.
- Check the installer is MCS certified. Without it you lose SEG, and most manufacturer warranties expect it.
- Get the EPC question answered early. If your home has a poor rating and you are on benefits, ECO4 may cover far more than solar, and insulation first is usually the better order of work.
- Do not wait for a better scheme. ECO4 closes at the end of 2026 and the zero VAT rate ends in March 2027. Both current concessions have an expiry date; the replacement does not exist yet.
The bottom line
There is no universal solar grant in 2026, and anyone telling you otherwise is selling something. What there is: full funding through ECO4 if you are on qualifying benefits and your home needs the work, zero VAT for everyone until March 2027, and ongoing export payments once your system is running.
If you think you might qualify for ECO4, apply this year. If you do not, the question is not “which grant” but “does this stack up for my roof”, and that needs a real quote.
