Are there any solar panel grants in the UK 2026?

In 2026, the main UK solar grant is ECO4 (Energy Company Obligation), which provides up to £10,000 for eligible low-income households. Additionally, all solar installations benefit from 0% VAT (saving £1,000-1,500), and the Smart Export Guarantee pays 12-15p per kWh for exported electricity. Some councils offer local grants of £500-2,000.

Who qualifies for ECO4 solar panel grants?

ECO4 eligibility requires receiving means-tested benefits (Universal Credit, Pension Credit, Child Tax Credit, Income Support, or similar) OR having a household income under £31,000 AND an EPC rating of D-G. The scheme covers up to £10,000 for combined solar panels and home insulation improvements.

How much is the 0% VAT saving on solar panels?

The 0% VAT on solar installations (available until March 2027) saves 20% on all costs. For a typical £6,000 system, this saves £1,200. The zero rating applies to solar panels, batteries (when installed with panels), inverters, and installation labour.

Solar Panel Grants & Subsidies UK 2026: Complete Guide to Funding

Key Grants Available in 2026: ECO4 government scheme (up to £10,000 for eligible households), 0% VAT on all solar installations introduced in April 2022 (saves £1,000-1,500), Smart Export Guarantee mandated by UK government (12-15p/kWh for exported electricity), and various local council grants (£500-2,000). While there's no universal grant for everyone, these schemes significantly reduce costs.

ECO4: The Main Solar Grant Scheme

The Energy Company Obligation (ECO4) is a UK government scheme running until March 2026 and provides the most substantial solar grants available to eligible UK households.

Who Qualifies for ECO4?

You must meet ONE of these criteria:

Receive means-tested benefits (Universal Credit, Pension Credit, Income Support, Child Tax Credit, JSA, ESA, Working Tax Credit, Housing Benefit)
Household income under £31,000 AND Energy Performance Certificate (EPC) rating of D, E, F, or G
Referred by your local council as "vulnerable to cold"

What ECO4 Covers

ECO4 provides up to £10,000 for whole-house energy improvements, which can include:

Solar panels (typically 3-4kW systems)
Loft and wall insulation
New heating systems
Solar battery storage (when combined with panels)

Important: ECO4 rarely funds solar panels alone. The scheme prioritises insulation first. You'll typically receive solar panels as part of a package that includes loft insulation, cavity wall insulation, or similar improvements.

0% VAT: Everyone's "Grant"

The most valuable benefit available to ALL solar panel buyers is the 0% VAT rate on installations, a UK government policy introduced in April 2022 and extended through March 2027.

System Size	Cost at 20% VAT	Cost at 0% VAT	Your Saving
3kW	£5,400	£4,500	£900
4kW	£6,600	£5,500	£1,100
6kW	£9,000	£7,500	£1,500

The 0% VAT applies to solar panels, inverters, batteries (when installed with panels), mounting equipment, and labour. This is effectively a £900-1,500 grant that everyone receives automatically.

After March 2027: VAT is expected to return to 5% for solar installations. If you're considering solar, installing before March 2027 saves an additional £250-400 compared to the 5% rate.

Smart Export Guarantee (SEG): Ongoing Payments

The Smart Export Guarantee (SEG) is a UK government scheme requiring energy suppliers to pay for exported solar electricity. While not technically a grant, SEG provides ongoing income, effectively subsidising your system.

How SEG Works: Energy suppliers pay you for every unit of electricity you export to the grid. Rates in 2026:

Supplier	Export Rate	Annual Payment (4kW System)
Octopus Outgoing Fixed	15p/kWh	£378
E.ON Next Export	12p/kWh	£302
OVO Energy	8p/kWh	£202
British Gas	4p/kWh	£101

Based on 70% export rate (2,520 kWh annually) for typical 4kW system.

Over 25 years, SEG payments add £7,500-9,500 to your total returns, making it a significant long-term subsidy.

Local Council Grants

Some councils offer additional solar grants, though availability varies widely:

Current Council Schemes (2026)

Warrington Borough Council: £1,000 grant for solar panels + £500 for battery storage
Scotland Home Energy Scotland: Interest-free loans up to £7,500
Wales Nest Scheme: Free solar for eligible low-income households
Various Scottish Councils: Grants of £500-2,000 through Area Based Schemes

Check your local council's website or call their energy advice service. Many councils don't widely advertise solar grants, so it's worth asking directly.

Interest-Free Loans and Finance Schemes

If you don't qualify for grants, several schemes offer affordable financing:

Scotland: Home Energy Scotland Loan

Interest-free loans up to £7,500
Cashback of £1,000-2,000 depending on measures installed
10-year repayment period
No credit check, income assessment only

Wales: Interest-Free Loan Scheme

Loans up to £5,000 for solar panels
5-10 year repayment
Managed by Welsh Government

Commercial Finance Options

Many solar installers offer finance packages:

Typical rates: 6.9-9.9% APR over 5-10 years
Monthly payments: £90-120 for £6,000 system over 5 years
Your solar savings often cover most/all of the monthly payment

What About the Feed-in Tariff?

The Feed-in Tariff (FIT) closed to new applicants in March 2019. If you installed solar panels before this date, you continue receiving FIT payments (typically 4-16p/kWh) for the remaining duration of your 20-year agreement.

New installations in 2026 use the Smart Export Guarantee instead, which offers similar or better rates (12-15p/kWh) than later FIT tariffs, though without the generation payment that early FIT recipients received.
