Are free solar panels real? What UK funding covers

What “free” really means

Some eligible households in England may be offered solar panels as one of several improvements, if the council has funding and the survey recommends them. Public money pays in limited cases only. However, it depends on your income, your home and where you live. For most households, panels are something you pay for yourself.

Be wary of any offer that says “free” with no conditions. The word usually hides a cost somewhere else, such as a loan, a contract or a long tie-in. Real schemes ask about your home and your income first, so a no-questions offer should worry you.

This guide covers the main routes. Each UK nation runs its own schemes, so the rules differ. Nothing here promises that you will qualify.

England: the Warm Homes: Local Grant

In England, the main route is the Warm Homes: Local Grant. GOV.UK says you could get free energy saving improvements if you are on a low income, get certain benefits or live in a certain postcode area. Solar panels are one of the improvements your council might suggest.

However, the offer is local. The council only arranges a survey if it has funding available. If you are eligible, GOV.UK says the council arranges and pays for the agreed work.

You can read the full rules on our page about solar funding routes in England. The home must be in England, belong to you or your landlord, and have an EPC of D to G. If you do not know your rating, you can find it out when you apply.

The Warm Homes Plan and what may come next

The government published its Warm Homes Plan in January 2026. It says low-income households could get support covering the full cost of rooftop solar. The word is “could”, not “will”. Therefore, treat it as an aim.

The plan also describes low-interest solar and battery loans. As of October 2026, we found no launch date. Check GOV.UK before you rely on it.

ECO4 is not a grant

Many “free panel” adverts lean on ECO4. Ofgem is clear that ECO is not a grant scheme. Energy suppliers decide what they fund, and you may be asked to contribute.

ECO4 only covers solar in limited cases, and the type of heating in the home matters. For example, the rules name heat pumps and some electric heating. The scheme runs until 31 December 2026. Our guide to ECO4 and solar panels in 2026 explains what has changed.

Scotland, Wales and Northern Ireland

In Wales, Nest lists solar panels among the improvements it may fund. Nest is a tailored package for eligible homes, not a promise of panels. Our page on solar funding routes in Wales has the detail.

In Scotland, Home Energy Scotland stopped funding solar for people who got an application link after 6 June 2024. Look at solar funding routes in Scotland for what is still available. Meanwhile, Warmer Homes Scotland may help some households. Ask Home Energy Scotland whether solar is included.

In Northern Ireland, nidirect says there is no financial support for homeowners who want to generate their own electricity. However, the Utility Regulator lists schemes under NISEP, some of which include solar. See solar funding routes in Northern Ireland and check the official list.

Who tends to qualify

Most schemes look at three things. They check your income, any means-tested benefits and your home’s energy rating. Because each scheme sets its own limits, you may qualify for one and not another. Therefore, check each route in turn.

These guides go deeper on each point:

• Solar panel grants for pensioners
• Solar funding if you get benefits
• Your EPC rating and solar funding

How to spot a false offer

A court case shows how this goes wrong. The Insolvency Service shut down a solar firm after 80 complaints about cold calls and unsolicited visits. The firm promised customers refunds from government grants, and they never got them.

Complainants in that case averaged 76, so older people can be at particular risk. Use these checks before you agree to anything:

• Did you ask for the contact, or did they approach you?
• Is the firm asking for a payment up front?
• Can you get the offer in writing, with the full price?
• Is the installer MCS certified, and can you check that on the MCS site?

You never have to decide on the spot. If you sign a contract at home, you usually have 14 days to cancel it.

If you pay for panels yourself

Without a grant, you can still cut the cost. GOV.UK shows VAT on installing solar panels at 0% until 31 March 2027, then 5%. Since suppliers pay for surplus power under the Smart Export Guarantee, you may also earn a little back. Our guide to choosing a Smart Export Guarantee tariff shows how to compare offers.

If you want prices, you can ask installers for quotes through our quote request page. That is optional and separate from any funding check.
