Can You Really Get Solar Panels Through ECO4 in 2026?
Yes, some households can still receive solar panels through ECO4 in 2026 — but the offer is much narrower than many “free solar panel grant” adverts suggest.
ECO4 now runs until 31 December 2026, following a nine-month extension. However, the Government did not increase the scheme’s overall obligation, so availability depends on energy suppliers, delivery partners and whether your whole-house retrofit produces enough qualifying energy savings. ECO4 is not an automatic grant that every eligible household can claim.
The biggest restriction is the heating system. Under Ofgem rules, solar PV is treated as a heating measure and is normally eligible only where the home has — or will receive — a hydronic heat pump, high-heat-retention electric storage heaters or another qualifying responsive electric heating system. A property heated primarily by gas, oil or LPG will not usually receive solar PV as a standalone ECO4 measure.
Check your ECO4 eligibility
Answer a few quick questions to see whether your household may qualify for ECO4 support.
Quick answer
You can genuinely get solar panels through ECO4 in 2026, but only in qualifying circumstances. Your household must meet an approved low-income, benefit, vulnerability or ECO4 Flex route; your property must normally have a low EPC rating; and the package must satisfy ECO4’s whole-house improvement rules. Solar PV is generally restricted to homes using suitable electric heating or a heat pump, because ECO4 counts it as a measure that reduces electric heating costs. Funding can cover all or part of the installation, but eligibility does not guarantee solar panels, approval or zero customer contribution. The scheme closes on 31 December 2026, and remaining capacity may be limited.
ECO4 solar eligibility at a glance
| Check | Likely requirement in 2026 | What it means |
|---|---|---|
| Location | Property in Great Britain | Northern Ireland uses different programmes |
| Household | Qualifying benefit, low income, vulnerability route or ECO4 Flex referral | Benefits are not the only route |
| EPC | Usually D–G for owner-occupiers; tighter rules for rented and social homes | A current assessment may be required |
| Heating | Qualifying electric heating or heat pump | Gas-heated homes are unlikely to receive solar alone |
| Property works | Insulation and minimum EPC improvement rules | Solar may form part of a larger package |
| Funding | Supplier and project dependent | Support may be full or partial |
Is ECO4 still available in 2026?
Yes. ECO4 was due to finish on 31 March 2026 but was extended to 31 December 2026. The extension gives obligated suppliers more time to complete existing targets and remedial work; it does not create a new, expanded solar fund. Availability may therefore be limited.
ECO4 places an obligation on medium and large energy suppliers to improve low-income, fuel-poor and vulnerable households. Ofgem administers the scheme, but households do not apply to Ofgem for a payment. Suppliers and their partners select projects.
Who can qualify for solar panels through ECO4?
The benefits route includes:
- Universal Credit
- Pension Guarantee Credit
- Pension Savings Credit
- Income Support
- Income-based Jobseeker’s Allowance
- Income-related Employment and Support Allowance
- Housing Benefit
- Child Benefit, subject to the applicable income limits
Owner-occupied homes generally need an EPC rating of D, E, F or G. Private rented homes generally need an E, F or G rating and the landlord’s permission.
ECO4 Flex can support households outside the main benefits route. Flex Route 1 covers gross annual household income below £31,000. Other routes may use approved indicators such as low-income council tax support, free school meals, energy debt, vulnerability to cold or specified serious health conditions. Participation varies by council.
Passing the household test is only the start. The heating, EPC improvement, insulation, roof and project economics must also work.
The heating-system rule most applicants miss
ECO4 does not treat solar PV as a general electricity-saving giveaway. It is eligible where the generated electricity helps run qualifying electric heating.
The home must have, or receive within the project:
- A hydronic heat pump
- High-heat-retention electric storage heaters
- An electric heating system with the required SAP responsiveness rating
Solar should not be installed where a non-electric primary heating system is planned, and some generated electricity must be available to heating equipment in the home.
That is why “benefit claimants get free solar” is incomplete: receiving a qualifying benefit does not override the heating and property rules.
Why insulation often comes before solar
ECO4 uses a fabric-first, whole-house approach. It aims to improve band D and E homes to at least band C, and band F and G homes to at least band D.
Heating measures are subject to insulation preconditions, which may require suitable loft, roof, wall or floor insulation to be fitted first or confirmed as adequate.
A proper assessment should examine the complete home. The package may combine insulation, heating, controls and solar PV.
This approach matters because installing renewable technology in a poorly insulated home may not provide the best overall reduction in heating costs. Reducing heat loss first can lower the amount of energy the household needs.
What could ECO4 pay for?
ECO4 has no fixed household tariff. The supplier decides which projects to support, which measures are included and the funding level.
Ofgem stresses that ECO4 is not a conventional grant scheme. Some households may be asked to contribute, and eligibility does not guarantee installation.
| Item | ECO4 position | Buyer check |
|---|---|---|
| Solar panels and inverter | Can qualify within an eligible project | Ask for system size, generation estimate and warranties |
| Insulation | Often required or included | Confirm what will be installed and how disruption is managed |
| Heat pump or electric heating | May form part of the package | Request running-cost calculations and controls training |
| Battery | May be installed but earns no ECO score | Confirm whether it is included and who pays |
| Customer contribution | Possible | Obtain the complete written price before signing |
| Self-funded benchmark | Typical 4.5kWp solar is about £7,600 | Use only as a broad comparison |
Ofgem caps ECO-scored solar capacity at 10kWp per home. Existing solar capacity counts towards that limit.
Batteries may be fitted during the retrofit, but they do not count as an ECO measure because they do not improve the property’s SAP rating. A provider may include a battery using another source of funding or as a customer-paid addition, but it should never be assumed to be free.
Energy Saving Trust’s current benchmark is around £7,600 for a typical 4.5kWp domestic system, although access, roof work and system design can substantially change the price.
An accurate quotation requires a property survey.
How to apply: a seven-step guide
Check the EPC
Find your property’s current energy rating. An outdated EPC may not reflect recent improvements, so another assessment may be required.
Check the household route
Review the qualifying benefits and ask your local council whether it operates ECO4 Flex.
Confirm the main heating system
Ask the assessor to explain in writing why solar qualifies under Ofgem’s heating rules.
Book a whole-house survey
The assessment should consider insulation, ventilation, electrics, roof condition, shading, orientation and expected generation.
Request the complete improvement package
Ask what measures are proposed, what EPC rating the project should achieve and whether any customer contribution is required.
Read the contract
Check the equipment models, scaffolding, roof repairs, electrical work, warranties, making good, monitoring and aftercare.
Verify the delivery chain
Solar microgeneration installers must meet the relevant MCS requirements. ECO work must also follow applicable PAS and consumer-protection processes.
Will ECO4 solar panels save money?
Solar panels generate electricity from daylight and still work on cloudy days, although output is much higher during brighter months.
Savings depend on:
- System size
- Roof orientation and angle
- Shading
- Location
- Electricity prices
- Household consumption
- How much solar electricity is used inside the home
Homes with electric heating or a heat pump can have high electricity demand, so solar may reduce daytime grid imports.
However, solar will not normally run the heating throughout winter. Generation is lowest during the months when heating demand is highest, and the household will still need grid electricity.
Surplus electricity may qualify for Smart Export Guarantee payments. Ask who will register the installation, provide the MCS documentation and help arrange the required export setup.
Why the installer matters
Installation quality affects safety, performance, warranties and lifespan.
Before work begins, obtain:
- The proposed system design
- Panel and inverter model numbers
- Estimated annual generation
- Product and workmanship warranties
- Details of relevant guarantees
- The installer’s identity
- The Retrofit Coordinator’s identity
- A clear aftercare and complaints process
Poor roof fixing, cable routing or badly coordinated insulation can create expensive defects. The suitability of the roof structure, inverter location and existing electrical installation should all be checked.
Ofgem’s complaints process points consumers towards the installer, scheme provider, TrustMark and relevant ombudsman routes when problems occur.
How to avoid misleading offers
Be cautious if a caller guarantees approval before checking your EPC, heating system and property.
A genuine provider should be able to explain:
- Which energy supplier or council supports the project
- Which eligibility route applies
- Why solar PV qualifies with your heating system
- Which other improvements are required
- Whether the installation is fully or partly funded
- Whether finance is involved
- Whether a battery is included
- Who owns the installed equipment
Verify the company through the supplier or council it claims to represent. Do not rely solely on a government-style logo, social-media advert or salesperson’s ID card.
Do not sign under pressure. Ofgem advises consumers to agree only after receiving a contract and to compare offers when a contribution is requested.
What if you do not qualify?
In England, the Warm Homes: Local Grant can fund measures including solar panels for eligible low-income households in privately owned EPC D–G homes, subject to council funding and a home survey. Scotland, Wales and Northern Ireland have different programmes.
Self-funded solar may also merit assessment, particularly for homes with:
- A largely unshaded roof
- High daytime electricity consumption
- An electric vehicle
- A heat pump
- Plans to remain in the property long term
Compare expected lifetime savings, warranties, inverter replacement costs and aftercare rather than choosing solely by panel count or headline price.

Yes, ECO4 solar panels are real in 2026 — but only for a relatively narrow group of households and properties.
You need an eligible household route, a low-performing home, a compliant whole-house plan and, crucially, suitable electric heating or a heat pump. The supplier then decides whether to fund the project and may offer full funding, partial funding or another package.
The next step is a transparent eligibility check and home survey. You should receive a clear explanation of each measure, cost, expected saving and aftercare responsibility.
