UK Solar Incentives and Grants Available in 2024

Introduction: The Current Incentive Landscape

While the UK's generous Feed-in Tariff scheme ended in 2019, several incentives remain available to help homeowners make solar energy more affordable. The government continues to support renewable energy adoption through various schemes, tax reductions, and export payments.

Understanding these incentives is crucial for calculating the true cost and payback period of your solar installation. In many cases, combining multiple incentives can reduce your initial investment by thousands of pounds and significantly improve your return on investment.

Smart Export Guarantee (SEG)

What is the Smart Export Guarantee?

The Smart Export Guarantee (SEG) replaced the Feed-in Tariff scheme in January 2020. Under SEG, electricity suppliers with more than 150,000 customers must offer tariffs to pay small-scale generators for excess renewable electricity they export to the grid.

How SEG Works

When your solar panels generate more electricity than your home uses, the excess is exported to the national grid. Energy suppliers pay you for this exported electricity at rates they set themselves, creating a competitive market for export tariffs.

Current SEG Rates (2024)

SEG rates vary significantly between suppliers:

• Octopus Energy: Up to 15p per kWh (Outgoing Fixed)
• British Gas: 3-7p per kWh
• E.ON: 4-5.5p per kWh
• EDF Energy: 3.5-8.4p per kWh
• SSE: 5.5p per kWh
• Scottish Power: 4p per kWh

Note: Rates change frequently. Always check current rates when planning your installation.

Eligibility Requirements

• Installation capacity up to 5MW
• MCS-certified installation
• Smart meter or export meter capable of half-hourly readings
• Installation commissioned after 1st January 2020 (or not previously claimed FIT)

Maximizing SEG Benefits

To get the most from SEG:

• Shop around for the best export rates
• Consider time-of-use tariffs that pay more during peak hours
• Size your system to maximize export without over-investing
• Monitor your export patterns to choose the best tariff type

VAT Reduction to 0%

Zero VAT on Solar Installations

Since April 1, 2022, residential solar panel installations are subject to 0% VAT instead of the standard 20%. This applies to both the equipment and installation costs, providing immediate savings of approximately 17% on your total investment.

What's Included

The 0% VAT rate applies to:

• Solar panels and mounting systems
• Inverters and electrical components
• Battery storage systems
• Installation labor costs
• Associated electrical work

Eligibility Criteria

• Installation must be on a domestic property
• Property must be used as a dwelling
• Installation must be carried out by a VAT-registered installer
• No minimum or maximum system size restrictions

Financial Impact

For a typical 4kW system costing £7,000:

• Previous cost with 20% VAT: £8,400
• New cost with 0% VAT: £7,000
• Immediate saving: £1,400

Local Council Grants and Schemes

Regional Variations

Many local councils offer additional solar incentives. These vary significantly by location and change frequently based on local priorities and available funding.

Types of Local Support

Direct Grants: Some councils offer grants ranging from £500 to £3,000 for solar installations, often targeted at low-income households or specific property types.

Interest-Free Loans: Several councils provide interest-free loans for renewable energy installations, typically repayable over 5-10 years.

Group Buying Schemes: Councils may organize group purchasing schemes to reduce costs through bulk buying power.

Notable Council Schemes

Warrington Borough Council: Offers solar panel grants up to £1,600 for eligible residents through their Green Energy Grant scheme.

Bristol City Council: Provides low-interest loans for renewable energy installations through their Energy Service.

Milton Keynes Council: Offers free solar panel installations for qualifying households through partnerships with social housing providers.

How to Find Local Schemes

• Check your local council's website
• Contact your council's environmental or sustainability department
• Search for "[Your area] solar grants" online
• Check local environmental groups and community organizations
• Ask your solar installer about local schemes they're aware of

ECO4 Scheme

Energy Company Obligation

The ECO4 scheme runs until March 2026 and requires large energy suppliers to help low-income and vulnerable households improve their home's energy efficiency. While primarily focused on insulation and heating, some solar installations may qualify.

Eligibility

ECO4 is primarily targeted at:

• Households receiving certain benefits
• Properties with an EPC rating of D, E, F, or G
• Low-income households in LA declarations
• Households with specific vulnerabilities

Solar Panel Inclusion

Solar panels may be included as part of a whole-house energy efficiency package, particularly when combined with insulation measures. Contact participating energy suppliers to check if solar installations are available through their ECO4 programs.

Green Finance Options

Green Mortgages

Several lenders offer green mortgage products with preferential rates for energy-efficient homes or those planning energy improvements:

• Barclays: Green Home Mortgage with cashback for EPC A or B properties
• NatWest: Green Mortgage with reduced rates for efficient homes
• Santander: Green mortgage products with cashback incentives
• Virgin Money: Green Additional Borrowing for home improvements

Specialist Solar Finance

Solar Loans: Several specialist lenders offer loans specifically for solar installations with competitive rates (typically 3-8% APR).

Credit Card Options: Some 0% purchase credit cards can be used for solar installations, though this requires careful planning to pay off before promotional rates end.

Personal Loans: Standard personal loans can be used, with rates varying based on credit score and loan amount.

Financing Comparison

For a £7,000 solar installation:

• Cash purchase: Best ROI, no interest costs
• Green loan (4% APR, 7 years): £107/month, total £8,988
• Personal loan (7% APR, 7 years): £114/month, total £9,576
• 0% credit card (paid off in 2 years): £292/month, total £7,000

Business and Commercial Incentives

Enhanced Capital Allowances

Businesses can claim 100% first-year allowances on solar panel installations, allowing the full cost to be offset against corporation tax in the year of installation.

Business Energy Efficiency Grants

Various schemes support business energy efficiency:

• Green Business Grants from local councils
• Carbon Trust support programs
• Sector-specific efficiency schemes
• Government innovation funding for larger installations

Power Purchase Agreements (PPAs)

Large commercial installations may qualify for Power Purchase Agreements, where a third party funds and maintains the installation in exchange for long-term electricity purchase agreements.

Future Incentive Changes

Upcoming Developments

Several potential changes could affect solar incentives:

• Heat and Buildings Strategy: May include additional support for renewable technologies

Conclusion

While the solar incentive landscape has changed significantly since the Feed-in Tariff era, substantial support remains available for UK homeowners. The combination of 0% VAT, Smart Export Guarantee payments, and various local schemes can significantly improve the economics of solar installations.

The key to maximizing benefits is understanding all available incentives in your area and designing your system accordingly. Work with experienced installers who understand the current incentive landscape and can help you navigate application processes.

Remember that incentives can change, so it's important to stay informed and act promptly when favorable schemes are available. The long-term benefits of solar energy extend far beyond current incentives, making it a sound investment even as support mechanisms evolve.
