"Free solar panels": what is really on offer

Fully funded solar exists, but most households will not qualify. Here is who may qualify and what other “free solar” offers involve.

Who may get fully funded solar

Two schemes, and the routes into them are not identical.

ECO4 reaches households on a qualifying means-tested benefit — Universal Credit, Pension Credit, income-based JSA or ESA, Income Support, certain tax credits, or referred by a council under LA Flex, which can qualify households in fuel poverty or living with a health condition made worse by a cold home. It closes on 31 December 2026.

Warm Homes: Local Grant covers privately owned homes in England rated EPC D to G, and has three income routes: you need only one:

| Route | What it means | | --- | --- | | IMD income deciles 1–2 | Your area is among the most income-deprived. No income check at all. | | Low-income proxies | Qualifying benefits and similar indicators. | | Income threshold | Gross household income of £36,000 or less. |

The first is the one people miss, and it is the reason to check your postcode before you conclude you earn too much.

The schemes are real, but eligibility is narrow and the funded package may not include solar.

The other three things called “free solar”

1. Rent a roof

A company installs panels at no cost to you and keeps the export income, in exchange for a lease over your roof, typically 20 to 25 years.

The panels really are free. The roof rights are the price, and they outlast most people’s plans. A long roof lease can complicate a remortgage or a sale, and some lenders will not lend against one without the lease being varied. That is a decision to take to a solicitor, not to a doorstep.

2. The doorstep version

Unsolicited contact, an offer framed as free or as a scheme you have been “selected” for, and pressure to sign today. What is usually being sold is a finance agreement, and the “free” part is either the survey or a discount that was never real.

The rules are simple and they work: never sign on the day, never pay a deposit for something described as free, and check the company on the MCS register under the exact name on the paperwork. The full list of warning signs.

3. “Free” meaning zero upfront

A finance agreement with nothing to pay on day one. That is not free, it is credit, and the total cost over the term is the number that matters.

We do not introduce anyone to a lender: that is a regulated activity we are not authorised for. So we have no interest in whether you take finance. We do have an interest in the word being used accurately.

If you do not qualify: what everyone gets

Two things apply regardless of income:

• 0% VAT on domestic installations until 31 March 2027, after which it reverts to 5%. Nothing to apply for; a compliant installer zero-rates the invoice.
• The Smart Export Guarantee, which pays you for every unit you export. The rate varies enormously between suppliers and the best headline numbers are usually tied to taking your import supply from the same company.

Neither makes solar free. Both are real, and both apply to the large majority of people who arrive at this page.

The three questions that settle it

• Do you meet any one of the three income routes: IMD deciles 1–2, a qualifying benefit, or under £36,000?
• Is your EPC rating D to G? Look it up free on the government register.
• Is the home privately owned: by you, or by a landlord willing to be the applicant?

Three yeses and it is worth pursuing. Otherwise the funded route may not be open to you. The eligibility checker will tell you on screen, without asking for your email first.
