Can You Get Solar Panels for Free in the UK?
Author: Steve Fairless
Originally Published: 17th June 2024 · Updated: 3rd September 2026
There is no universal UK Government grant that gives every homeowner free solar panels. However, some eligible households can receive fully funded energy-efficiency improvements that may include solar PV through targeted schemes such as the Warm Homes: Local Grant in England, and solar can also appear within certain ECO4 projects under specific conditions.
At Sustainable Energy Engineering, we think the important distinction is between genuinely funded work, finance that still has to be repaid, and a commercial offer marketed as "free" because another party owns or controls the equipment. Those are not the same thing.
Funding rules change, local availability matters and not every eligible home will receive solar specifically. We therefore advise customers to check the current official scheme route before relying on an advert or paying an application fee.
If you are not eligible for a fully funded route, we can still assess whether a conventional domestic solar PV system or solar with battery storage makes sense for your home. We provide the design and quotation separately from any government eligibility decision.

Free Solar Panels in 2026: The Short Answer
- No universal free-solar grant exists for every UK homeowner. Energy Saving Trust explicitly notes that there are no dedicated UK Government solar-panel grants for everyone.
- Warm Homes: Local Grant can fully fund agreed improvements for eligible households in England. Solar panels are one of the measures a local council may recommend after assessment.
- ECO4 can support solar PV in specific eligible projects. It is not a blanket entitlement to free panels.
- Low- and zero-interest finance is not "free". The Warm Homes Plan includes a major finance programme, but loans remain finance and rollout/availability must be checked.
- Always confirm ownership, warranties and ongoing obligations. A no-upfront-cost commercial arrangement can differ substantially from a grant-funded installation.
What Does "Free Solar Panels" Actually Mean?
The phrase is used for several very different arrangements. A fully funded government/local-authority measure can mean the eligible resident does not pay for the agreed installation. A loan can remove or reduce the upfront payment but still has to be repaid. A commercial third-party ownership arrangement can involve no purchase cost while giving another organisation contractual rights over the system or roof.
Before agreeing to anything, identify which of those categories applies.
Warm Homes: Local Grant Can Include Solar Panels
The official GOV.UK application service says eligible households in England can receive free energy-saving improvements where the local council has funding and agrees the measures. Solar panels are specifically listed as one of the improvements a council may suggest after a home survey.
The council then organises and pays for the agreed work. This is the clearest current example of a route that can genuinely result in no homeowner payment for an eligible owner-occupier, subject to the scheme rules and local decision.
Who Can Qualify for Warm Homes: Local Grant?
The GOV.UK eligibility page states that the home must be in England, privately owned and normally have an EPC rating of D, E, F or G. Household income must usually be £36,000 a year or less, although certain postcode or benefit routes can allow eligibility above that figure.
A landlord may have to contribute in some circumstances. Eligibility also does not guarantee that solar will be the chosen measure; the survey determines which upgrades are suitable for the property.
What "Fully Funded" Means Here
For an eligible household where the council approves solar as part of the Warm Homes: Local Grant work, GOV.UK states that the council will organise and pay for the agreed improvement work and the resident will not need to pay for it.
Can ECO4 Pay for Solar Panels?
ECO4 is an energy-company obligation aimed at improving eligible homes. Solar PV can be used within ECO4 in defined circumstances, but the technical and household eligibility rules mean it should not be advertised as a universal free-panel scheme.
Ofgem s current ECO4 delivery guidance reflects the scheme extension to the end of 2026. If an installer or lead generator says ECO automatically gives you solar, ask them to identify the exact eligibility route and measure package.
What About the Warm Homes Plan?
The 2026 Warm Homes Plan commits major public investment for home upgrades, with direct support for low-income households and new low- and zero-interest finance intended to widen access to solar, batteries and other technologies. The plan is significant, but a finance product is not the same as a free grant.
Availability is being delivered in phases and through different programmes. We recommend using current GOV.UK pages for the specific scheme rather than relying on an old headline about future support.
Energy Saving Trust s Current Position on Solar Grants
Energy Saving Trust states that there are currently no dedicated UK Government solar panel grants. It also notes that solar can be funded through other government schemes and highlights the Warm Homes Plan. This distinction is important because it prevents a targeted support programme being presented as something available to every homeowner.
The right question is therefore not "where is the free solar grant?" but "which current scheme, if any, applies to my household and property?"
| Route | What it means | What we would check |
|---|---|---|
| Warm Homes: Local Grant | Targeted local-authority support in England that can include solar where the household, property and assessment meet the scheme rules. | Eligibility, the measure package proposed after assessment and exactly what the grant covers. |
| ECO4 | Energy-supplier obligation support for eligible households; solar can form part of qualifying improvement work in the right circumstances. | Whether the household and property qualify and whether solar is included in the approved package. |
| Warm Homes Plan | A wider government programme that includes fully funded support for some low-income households and other finance routes as delivery develops. | Which live scheme or finance route applies at the time, rather than treating the policy headline as a universal free-solar offer. |
| Private solar purchase | Not a grant: the homeowner buys or finances an owned system and receives the generation and export benefits. | Installed specification, expected generation, finance terms where relevant and the complete long-term cost. |
Be Careful With "No Upfront Cost" Offers
No upfront payment does not automatically mean the system is a grant. Read the contract to establish who owns the panels, who receives export income, who is responsible for maintenance, how long the agreement lasts and what happens if the property is sold.
We would not recommend signing a long-term energy or roof agreement solely because an advert uses the word "free".
How to Check a Funding Offer Before You Commit
Questions We Would Ask
- What is the exact official scheme name?
- Which government department, local authority or regulated programme funds it?
- What household and EPC eligibility route is being used?
- Will the homeowner own the solar system after installation?
- Is any loan, charge, lease or roof agreement involved?
- Who receives export payments?
- Who is responsible for warranties, servicing and removal if the roof needs work?
- Is any upfront fee being requested simply to apply for a government scheme?
Do Not Pay for an "Eligibility Certificate" Without Checking
Official schemes set out their application route. If a company pressures you to pay for a certificate, survey or application before it will even identify the scheme, check the official GOV.UK or Ofgem information first.
A legitimate solar project can include chargeable professional work in some contexts, but the funding route should be transparent and independently verifiable.
What If You Are Not Eligible for Free Solar?
That does not mean solar is unsuitable. A conventional owned system can still reduce purchased electricity and may receive export payments. The financial case should be modelled from your roof, electricity use and current tariff rather than compared with a grant you cannot access.
Energy Saving Trust currently quotes around £7,600 for an average 4.5 kWp home system, giving a useful benchmark before property-specific quotation.
Can Export Payments Help With the Cost?
The Smart Export Guarantee is not an installation grant. It is a mechanism under which eligible small generators can be paid for electricity exported to the grid. Supplier rates and contract terms vary.
We separate export income from the purchase price so customers can see the difference between funding the installation and earning value from the system after it is operating.
Our Recommendation on Free-Solar Claims
Start with the official scheme, not the sales advert. If you qualify for targeted support, use the published government or Ofgem route and understand exactly what is funded. If finance is involved, treat it as finance. If a third party will own the system, read the ownership and property obligations carefully.
Where there is no applicable funded scheme, compare an owned solar installation on its own merits rather than waiting for a universal free-panel programme that does not currently exist.
Not Eligible for a Funded Scheme? We Can Still Assess Solar Properly
We can design a conventional owned solar system around your property and electricity use, with a clear quotation and realistic performance estimate.
