Free Solar Panels UK
Find out if you qualify for fully funded solar panels under the ECO4 grant — no upfront cost. Free 60-second eligibility check.
Check your eligibility free“Free solar panels” in the UK are delivered through the government-backed ECO4 scheme, which funds energy efficiency improvements — including solar PV — for eligible low-income and vulnerable households at no upfront cost. The scheme is funded by the major energy suppliers under their Energy Company Obligation.
Solar is installed where it is the most appropriate measure for your property, often alongside insulation and heating upgrades. The sections below explain who qualifies, how to apply, and how to avoid the common “free solar” scams.
Free Solar Panels — FAQs
Are free solar panels real in 2026?
Yes. Under the government ECO4 scheme, eligible UK households can receive solar panels fully funded with no upfront cost, where solar is the most appropriate measure for the property. The scheme is funded by energy suppliers and runs to March 2026, with successor schemes expected.
Who qualifies for free solar panels?
Eligibility typically requires receiving a qualifying benefit (such as Universal Credit, Pension Credit, Income Support or Child Benefit within income thresholds) and living in a property with an EPC rating of D or below. LA Flex routes let some councils widen eligibility to lower-income households not on benefits.
How do I apply for free solar panels?
Start with a free eligibility check. If you qualify, an MCS-certified installer carries out a free home assessment, the ECO4 application is submitted on your behalf, and approved installers fit your system at no cost.
Is there a catch with free solar panels?
The main conditions are genuine eligibility (benefits and EPC), using an approved installer, and that solar is the right measure for your home. There are no hidden fees under a properly administered ECO4 grant — be cautious of any provider asking for upfront payment.

Start my free checkAre free solar panels real, or is it a scam? The honest answer
It is a fair question, and the short answer is: genuinely free solar panels are real for some households, but not for everyone — and a lot of what gets advertised as “free solar” is not free at all. The confusion comes from two very different things sharing the same headline.
The real version is government-backed funding. Under the ECO4 scheme (the Energy Company Obligation, funded by the major energy suppliers and running to around March 2026, with successor schemes expected), eligible low-income and vulnerable households can have solar PV installed with no upfront cost and nothing to repay — where solar is the most appropriate measure for the property. You own the system and keep all the savings. That is the legitimate, “actually free” route.
The misleading version is the sales pitch. Some installers advertise “free solar panels” to mean a finance deal, a roof-rental arrangement, or a quote that simply applies an unrelated discount. If you do not meet ECO4 eligibility, the honest position is that you are usually paying — either directly or over time. Knowing which version you are looking at is the whole game, and the sections below show you exactly how to tell them apart.
Who actually qualifies for free (fully-funded) solar panels
Genuinely free solar under ECO4 is means-tested, so eligibility hinges on two things: your household circumstances and your property. As a guide, you typically need someone in the home receiving a qualifying benefit, and a property that is currently energy-inefficient.
Qualifying benefits commonly include:
- Universal Credit
- Pension Credit (Guarantee Credit)
- Income Support
- Income-based Jobseeker’s Allowance (JSA) or Employment and Support Allowance (ESA)
- Working Tax Credit / Child Tax Credit
- Housing Benefit
On the property side, homes with a lower EPC rating (typically D to G) are prioritised, because the scheme targets the least efficient housing first. You do not need to be on benefits in every case: under LA Flex (ECO Flex) some councils widen eligibility to lower-income households not claiming a listed benefit, via an income route, a health-condition route, or a proxy. Crucially, solar is funded where it is the right measure for your home — sometimes insulation or heating is fitted first. Because the rules vary by household and council, the only reliable way to know is a free eligibility check. There is never a guarantee of approval.
How to get free solar panels: the step-by-step process
If you think you might qualify, the legitimate ECO4 route follows a clear, no-cost path. You should not pay anything at any stage of a properly administered grant.
- 1. Free eligibility check. Confirm your benefit status, property type and EPC band. This takes a couple of minutes and tells you whether it is worth proceeding — with no obligation.
- 2. Free home survey. An MCS-certified installer assesses your roof orientation, shading, electrics and existing energy efficiency to confirm solar is the appropriate measure.
- 3. Grant application. The installer submits the ECO4 application on your behalf and liaises with the funding energy supplier — you do not deal with the paperwork.
- 4. Installation at no cost. Once approved, approved installers fit the system. Where solar is fully funded, the grant covers supply and installation, though in some cases a small contribution can apply.
- 5. Sign-off and ownership. You receive certification (including MCS paperwork), you own the panels outright, and you keep the bill savings — plus any export payments via the Smart Export Guarantee.
If you do not qualify for full funding, you are not out of options: solar still pays back over time when bought outright, and export payments add to the return. The key rule throughout: a real free-solar grant never asks you for money up front.
How to spot a free solar panel scam
Because the genuine ECO4 route is free, any request for an upfront fee, deposit or admin charge to “secure your grant” is the clearest red flag there is. Legitimate grant funding is paid by the energy suppliers, not by you. Treat these warning signs seriously:
- Upfront payments or “refundable” deposits. A real grant install costs you nothing — walk away from anyone who asks.
- Pressure and fake deadlines. “Today only” or “last few grants left” tactics push you to sign before you can check the company.
- “Rent-a-roof” deals dressed up as free. Here a company installs panels free but keeps the electricity or the export income, and the long contract can complicate selling or remortgaging your home. That is not the same as owning fully-funded panels.
- Vague eligibility claims. A genuine provider checks your benefits, EPC and property; a scam promises “everyone qualifies”.
- No MCS certification. Funded installs must use MCS-certified installers — ask for the number and verify it.
Protect yourself: confirm the installer is MCS-certified, never pay to apply, and get everything in writing before you agree to anything. If a deal sounds too good and comes with a contract you do not fully understand, take time to read it — a legitimate grant has nothing to hide.
| Type of “free” solar | Is it actually free? | Who owns the panels | What to watch for |
| ECO4 fully-funded grant | Yes — no upfront cost, nothing to repay (for eligible homes) | You own them outright | Must meet benefit + EPC eligibility; uses MCS-certified installer; never pay to apply |
| Bought outright with any available grant/discount | No — you pay (typically around £5,000–£9,000 for a 3–4kW system before any funding) | You own them outright | Pays back over time; check the quote and that grants are genuine, not just marketing |
| Finance / “pay monthly” solar | No — spread cost plus interest | You own them (often once the agreement ends) | Compare total repayable; “free” usually means “no deposit”, not no cost |
| Rent-a-roof arrangement | Free to install, but you give something up | The company owns the panels | They may keep the electricity or export income; long contract can affect selling/remortgaging |
Frequently asked questions
Are free solar panels real in the UK in 2026?
Yes, for eligible households. Under the government-backed ECO4 scheme, funded by the major energy suppliers, qualifying low-income and vulnerable homes can have solar PV installed with no upfront cost and nothing to repay, where solar is the most appropriate measure. The scheme runs to around March 2026, with successor schemes expected. If you do not qualify, beware deals advertised as free that are actually finance or roof-rental arrangements.
Why does Reddit say free solar panels are a scam?
Much of the scepticism comes from misleading sales pitches, not the genuine grant. Some companies advertise free solar to mean finance deals, rent-a-roof contracts, or quotes with unrelated discounts, and a few ask for upfront fees to secure a grant that should cost nothing. The real, fully-funded route is ECO4 for eligible households. Once you separate legitimate grant funding from the sales spin, the picture is far clearer than an anonymous thread suggests.
How do I get free solar panels with no upfront cost?
Start with a free eligibility check based on your benefits, EPC rating and property type. If you qualify, an MCS-certified installer carries out a free home survey, submits the ECO4 application on your behalf to the funding energy supplier, and fits the system at no cost once approved. You then own the panels and keep the savings. A genuine grant never asks you to pay to apply, so treat any upfront fee as a warning sign.
Do free solar panels exist in Scotland and Wales?
It varies by nation. In Scotland, Home Energy Scotland offers solar PV as an interest-free loan rather than a grant, though fully-funded support exists for low-income households through Warmer Homes Scotland for eligible measures. In Wales, the Nest / Warm Homes Wales scheme provides free measures for eligible households. ECO4 operates across Great Britain. Because rules differ, an eligibility check tailored to where you live is the reliable way to know what funding applies to your home.
What is the catch with free solar panels?
With a properly administered ECO4 grant there is no hidden catch: no upfront fee, and you own the system. The genuine conditions are that you must meet the eligibility criteria, use an approved MCS-certified installer, and that solar is the right measure for your property. The real catches appear in lookalike deals, such as rent-a-roof contracts where a company keeps your electricity or export income, or providers charging to apply. Always check eligibility, certification and any contract before agreeing.
