The UK government does not offer a universal solar panel grant in 2026 — but that doesn’t mean there’s no financial support available. Several schemes reduce the cost or increase the return on a solar investment, and some households qualify for free solar installation entirely.
This guide covers every solar support mechanism available to UK homeowners in 2026: who qualifies, how much they’re worth, and how to apply.
What solar grants are available in the UK in 2026?
The main solar support schemes in the UK in 2026 are: the Smart Export Guarantee (SEG), which pays homeowners for electricity exported to the grid; ECO4, which provides free solar for eligible low-income households; 0% VAT on residential solar installations; and various council and regional energy efficiency grant schemes. There is no universal free solar grant, but significant financial support is available depending on eligibility.
1. Smart Export Guarantee (SEG) — Available to All
The Smart Export Guarantee is the most widely available solar support mechanism in the UK. It is not a grant — it is a tariff that pays you for electricity your solar panels generate but your home does not use, which is exported to the National Grid.
Since January 2020, all energy suppliers with 150,000+ customers are legally required to offer an SEG tariff. You choose which supplier to export with — it doesn’t have to be your import supplier.
Tariff Type
Fixed Rate
Rate Range: 4p – 15p per kwh
Notes: Set rate regardless of time of day. Simpler to manage
Tariff Type
Flexible / Smart Rate
Rate Range: Variable — sometimes 0p, sometimes 20p+
Notes: Higher potential earnings if you can control export timing.
Tariff Type
Octopus Flux
Rate Range: ~19p per kWh peak
Notes: Requires smart meter and battery. High earner.
Tariff Type
E.ON Next Drive
Rate Range: ~15p per kWh
Notes: Competitive fixed option for 2026.
SEG eligibility requires MCS certification on your installation. A typical 4kWp system exports 40–50% of generation — approximately 1,400–1,700 kWh/year. At 10p/kWh average SEG rate, that’s £140–£170/year in additional income.
2. ECO4 Scheme — Free Solar for Eligible Households
The Energy Company Obligation (ECO4) is the UK’s primary mechanism for delivering free energy improvements — including solar panels — to low-income and vulnerable households. The current phase runs to March 2026, with ECO5 expected to follow.
Who Qualifies for ECO4 Solar
Eligibility is based on a combination of benefits entitlement and EPC (Energy Performance Certificate) rating. You are likely to qualify if you receive one of the following benefits AND have an EPC rating of D, E, F, or G:
- Universal Credit
- Child Tax Credit or Working Tax Credit
- Pension Credit (Guarantee Credit)
- Housing Benefit
- Income Support
- Income-based JSA or ESA
- Child Benefit (with income cap of £31,000 for England and Wales)
Owner-occupiers and private renters (with landlord consent) can apply. Council and housing association tenants may be covered by their landlord’s ECO4 obligations — check with your housing provider.
How to Apply for ECO4
- Check eligibility at gov.uk/energy-company-obligation
- Contact your energy supplier — they are obligated to refer you to their ECO4 delivery partner
- Or use a government-approved ECO4 broker to access funding through multiple suppliers
- A survey is conducted to assess your property’s suitability
- If approved, installation is arranged at no cost to you
3. 0% VAT on Residential Solar — Worth £600–£900
Since April 2022, the installation of residential solar panel systems in the UK attracts 0% VAT, down from the previous 5% rate. This is not a grant — it’s a tax exemption built into the price of every qualifying installation.
On a typical £7,500 installed solar system, 0% VAT versus the pre-2022 5% rate saves approximately £375. This saving is automatic and already reflected in all installer quotes — you don’t need to apply for it.
Q: Is there a government grant for solar panels in 2026?
There is no single universal government grant for solar panels in the UK in 2026. However, several support mechanisms exist: the ECO4 scheme provides free solar for eligible low-income households; the Smart Export Guarantee pays homeowners for exported electricity; and all residential solar installations attract 0% VAT. Some local councils and combined authorities also offer energy efficiency grants. Total support available varies significantly by household eligibility.
4. Council and Local Authority Solar Grants
Many UK local authorities run their own energy efficiency grant schemes that can fund solar panel installation. These vary significantly by area and are subject to periodic availability.
Examples of local solar grant programmes in 2026 include:
- Greater Manchester Combined Authority — Warm Homes Greater Manchester fund
- West Yorkshire Combined Authority — Home Upgrade Grant (HUG2)
- Bristol City Council — Warm Homes Bristol programme
- South Yorkshire MCA — South Yorkshire Energy Efficiency grants
- Various county councils — Local Authority Delivery (LAD) scheme funding
To find current schemes in your area: search ‘[your council name] home energy efficiency grant 2026’ or visit gov.uk/improve-energy-efficiency for the central signposting tool
5. Home Upgrade Grant (HUG2) — Off-Gas Rural Properties
The Home Upgrade Grant Phase 2 targets owner-occupied properties not connected to the gas grid, with low EPC ratings. Solar panels are an eligible measure. Funding is delivered through local authorities — contact your council’s energy team to check HUG2 availability in your area.
6. What the Government Is NOT Offering in 2026
Several schemes that previously existed have ended or changed. It is worth knowing what no longer applies:
- Feed-in Tariff (FIT) — closed to new applicants in March 2019. Existing FIT recipients continue to receive payments.
- Renewable Heat Incentive (RHI) — closed. Replaced by the Boiler Upgrade Scheme (not solar).
- Green Homes Grant — closed in 2021.
- 0% VAT does NOT apply to commercial solar installations or solar installed purely for export.
7. How to Maximise Your Solar Support in 2026
- Check ECO4 eligibility first — if you qualify for free solar, there’s no reason to pay
- Ensure your installer is MCS-certified — required for SEG and ECO4
- Register for the best-rate SEG tariff within 30 days of installation going live
- Check your local council website for current energy grant availability
- Get at least 3 quotes — government support does not remove the need to compare prices
Frequently Asked Questions — Solar Grants UK
Can I get free solar panels in the UK in 2026?
Yes, if you qualify for the ECO4 scheme. Eligibility requires being in receipt of certain means-tested benefits (Universal Credit, Pension Credit, etc.) and having a home with an EPC rating of D or below. Owner-occupiers and some private renters are eligible. Check gov.uk/energy-company-obligation or contact your energy supplier to check eligibility.
How much is the Smart Export Guarantee worth?
A: A typical 4kWp solar system exports approximately 1,400–1,700 kWh per year. At an average SEG rate of 10p/kWh, this generates £140–£170/year in export income. On higher-rate tariffs (Octopus Flux, E.ON Next Drive) annual SEG income can reach £250–£350 for the same system. Total SEG income over 20 years ranges from £2,800 to £7,000 depending on tariff choice.
Do solar panels increase my council tax?
No. Solar panel installations do not affect council tax assessments in England, Scotland, or Wales. They are not considered a material change that increases a property’s council tax band.
