UK Government Solar Incentives in 2026: What Homeowners Need to Know

The cost of solar energy in the UK has dropped significantly, but installing a premium oak frame solar carport still represents a substantial investment. The good news: the UK government offers multiple schemes to help offset the cost, from VAT relief to direct grants and export payments.

Whether you're considering a simple pergola or a full solar carport with battery storage and EV charging, there are incentives available to you. Let's walk through every scheme currently available in 2026 and how to access them.

1. Zero VAT on Solar Panels (Extended)

The biggest financial incentive is reduced VAT. Since January 2022, solar panel systems have been subject to 0% VAT instead of the standard 20%, making them significantly more affordable.

How it Works

When you purchase a solar carport from Oak Frame Solar, the solar tiles and installation are charged at 0% VAT. This isn't a rebate or grant—it's a direct reduction in the cost.

The Saving

On a £50,000 oak frame solar carport system:

• Without 0% VAT: £60,000 (20% VAT applied)
• With 0% VAT: £50,000
• Direct saving: £10,000

Important note: While the solar tiles qualify for 0% VAT, the oak frame structure itself (the "building") is currently subject to standard VAT. Only the solar tile components, inverters, and battery storage (if ordered together) benefit from the 0% rate. Oak Frame Solar's prices reflect this breakdown.

How to Access

Nothing to do—you automatically receive 0% VAT when you purchase a solar system from a registered installer like Oak Frame Solar.

2. Smart Export Guarantee (SEG)

SEG is an ongoing payment scheme, not a one-time grant. If your solar carport generates excess electricity that you export to the grid, energy suppliers will pay you for it.

Current Rates (2026)

SEG rates vary by supplier, but typically range from 11p to 15p per kWh exported. This means:

• A 4kW carport exporting 1,400 kWh annually: £150-£210 per year
• A 6kW carport with battery storage exporting 1,000 kWh: £110-£150 per year
• An 8kW carport with EV charging exporting 400 kWh: £44-£60 per year

Over 10 years, this represents cumulative savings of £1,100-£2,100 depending on your system.

Eligibility

You're eligible if your system is MCS certified (all Oak Frame Solar installations are). No income limits, no location restrictions. Every UK homeowner with solar can claim SEG.

How to Access

After your solar carport is installed and commissioned, register with your chosen energy supplier (usually online or by phone). Provide your MCS certificate number. Payments typically begin within 4-6 weeks.

3. ECO4 (Energy Company Obligation) – for Low-Income Households

ECO4 is a government-backed scheme that requires large energy suppliers to fund energy-saving improvements for low-income households, off-grid properties, and those in rural areas.

Eligibility

You qualify if you:

• Receive certain benefits (Universal Credit, Income Support, Child Tax Credit, Pension Credit, etc.)
• Own or are purchasing a property that meets Energy Performance Certificate (EPC) criteria
• Have occupied the same property for 12 months (minimum)
• Live in England, Scotland, or Wales (note: different schemes apply in each)

What ECO4 Can Fund

Solar panels are eligible if they're part of a broader energy improvement package (e.g., alongside insulation, heat pump, or other energy-saving measures). You cannot receive solar-only funding through ECO4 alone, but solar can be bundled with other improvements.

Potential grants: £3,000-£15,000 depending on the comprehensive package.

How to Access

Contact your energy supplier's ECO4 team directly and discuss a comprehensive energy improvement plan. Oak Frame Solar can provide installation quotes that align with ECO4-eligible measures. The process typically takes 8-12 weeks from application to completion.

4. BUS Grant (Business to Support Grants) – for SME Businesses

If you run a small business (sole trader, partnership, or limited company with fewer than 50 employees), the BUS grant scheme can help fund solar installations.

How Much

Grants up to 40% of eligible costs, with a cap of £25,000 per installation. For a £50,000 solar carport, this could mean up to £20,000 back (40% cap).

Eligibility

• Your business is registered in the UK
• You have fewer than 50 employees
• You own or lease the property where the solar will be installed
• Annual turnover is less than £10 million

How to Access

Apply through your local authority's business grants team. Processes and availability vary by region, so contact your local council first. Typical application requires: business plan, quotes from installers, energy assessments, and proof of business registration. Process takes 6-12 weeks.

5. Local Authority Grants & Schemes

Some UK local authorities offer additional grants, loans, or subsidies for renewable energy. These vary significantly by region.

Examples Include

• Green Homes Grant (if still available locally): Up to £5,000 for energy improvements
• Council-run solar schemes: Some councils partner with installers to offer discounted rates or direct grants
• Energy efficiency loans: Some councils offer discounted loans for renewable energy at below-market rates
• Community energy grants: Some areas fund solar as part of community decarbonisation projects

How to Find Out

Contact your local council's climate or energy efficiency team directly. You can also search the Government's Energy Saving Trust website for your postcode to see current schemes in your region.

6. Energy Performance Certificate (EPC) Improvements

While not a direct cash grant, an improved EPC rating can have real financial value when you sell or rent your property. Solar installations typically improve your EPC rating by 1-2 bands.

The Impact

• Better rental income: If letting your property, better EPC = higher rental rates
• Increased resale value: Properties with solar and good EPC ratings attract premium prices (estimated £5,000-£15,000 uplift for a solar carport)
• Landlord compliance: From April 2020, landlords cannot let properties rated F or G. Solar can push you from F to E, making the property legal to let

This isn't an incentive from government, but the market value of a better-performing home is a real financial benefit.

How Solar Carports Specifically Benefit From These Incentives

Oak Frame Solar structures offer several advantages under UK incentive schemes:

Permanent Building = Better Recognition

Because our oak frame solar carports are permanent, load-bearing structures (not bolt-on systems), they're recognized as building improvements in your property appraisal. This improves their position for financing, EPC ratings, and potential future grant eligibility.

Integrated Systems = Efficiency Bonus

When solar, battery storage, and EV charging are integrated into one structure, they're often treated more favourably under ECO4 and energy efficiency schemes than separate bolt-on installations.

MCS Certification = Automatic Eligibility

All Oak Frame Solar installations come with full MCS (Microgeneration Certification Scheme) certification, making you instantly eligible for SEG, ECO4, and other government schemes without additional verification.

Combining Multiple Incentives

You can often combine multiple schemes. For example:

• Scenario 1 (Homeowner, Low-Income): 0% VAT + ECO4 bundle grant + SEG export payments
• Scenario 2 (SME Business): 0% VAT + BUS grant (40%) + SEG export payments + improved EPC value
• Scenario 3 (Standard Homeowner): 0% VAT + SEG export payments + EPC uplift value + potential local authority schemes

The combination of these often brings the effective cost of a solar carport down by 30-50% when all incentives are applied.

Important: Tax Implications

While most of these incentives are tax-free, it's worth noting that SEG payments are technically taxable income. However, you have a trading allowance of £1,000 per year, so only higher earners need to declare SEG income. Consult your accountant for details specific to your situation.
