Complete Guide to Solar Panel Grants and Funding in the UK

Investing in solar panels is a great way to cut energy bills and reduce your carbon footprint. With advancements in solar technology and growing government support, switching to renewable energy has never been more accessible. 

Power your home with Upvolt’s smart solar solutions.

The UK offers various incentives and funding options to help homeowners and businesses install solar panels without facing high upfront costs. This guide will walk you through the available programs and how to take advantage of them.

Solar Panel Grants and Funding: Everything You Need To Know 

• The UK offers several government-backed schemes to reduce solar panel installation costs and provide financial benefits.
• The Smart Export Guarantee (SEG) allows solar panel owners to earn money by selling surplus electricity back to the grid.
• VAT has been removed from solar panel installations until 2027.
• The Energy Company Obligation (ECO4) scheme offers free or subsidised solar panel installations for low-income and vulnerable households.

How Can Government Schemes and Financial Support Make Solar Energy More Accessible?

Switching to solar energy and improving home efficiency is more affordable than ever, thanks to a range of government-backed schemes. These initiatives help reduce installation costs and provide ongoing financial benefits.

Smart Export Guarantee (SEG) Scheme

The SEG scheme allows solar panel owners to earn money by selling surplus electricity back to the national grid. Under this program, energy suppliers must pay for the renewable electricity they generate and export, typically offering rates between 3p and 20p per kWh. For example, E.ON’s Next Export Exclusive tariff offers 16.5p per kWh, while British Gas provides 15.1p per kWh. 

A standard 3.5kW solar panel system in the UK produces around 3,000 to 3,500 kWh of electricity annually. Based on typical household energy usage, homeowners may export 1,000 to 1,500 kWh back to the grid. With an SEG rate of 15p per kWh, this could generate an additional income of £150 to £225 annually.

Zero VAT on Solar Panel Installations

To encourage more homeowners to switch to solar energy, the UK government has removed VAT on solar panel installations until 2027. This reduction from 5% to 0% lowers costs, making installations more affordable. For a typical £5,000 solar panel system, for instance, homeowners can save around £250.

This VAT exemption is a key financial incentive that helps reduce the initial financial barrier and supports the government’s broader commitment to increasing renewable energy adoption and reducing carbon emissions. 

The Energy Company Obligation (ECO4) Scheme

The Energy Company Obligation (ECO4) scheme provides free or subsidised energy-efficient home improvements, including solar panels. The scheme targets low-income and vulnerable households, particularly those living in properties with poor energy efficiency (EPC rating of D, E, F, or G). 

Homeowners and tenants in private or social housing may qualify if they receive benefits such as Universal Credit, Pension Credit, or Income Support. 

Some local councils may also offer funding through the Flexible Eligibility (ECO4 Flex) scheme, which allows households that do not receive benefits but are still struggling with energy costs to apply.

Warm Homes Plan 

Launching in 2025, the Warm Homes Plan aims to fund energy-efficient upgrades, including solar panel installations, for low-income households, with thousands of families set to receive energy performance and clean heating upgrades in the form of insulation, solar panels, and heat pumps.

Local Authority Grants and Regional Schemes

In addition to national government initiatives, many local councils across the UK offer additional grants, funding programs, and incentives to support the installation of solar panels. These regional schemes can vary widely depending on where you live, with some councils offering up to 100% funding for eligible low-income households, while others provide rebates or low-interest loans to reduce installation costs. 

It’s worth checking with your local authority to see what specific schemes are available in your region, as these programs can make the transition to solar even more affordable and accessible. 

Interest-Free Loans & Solar Panel Financing Options

Some solar panel installers offer financing options to help homeowners install solar panels without paying the full amount upfront. These options make solar energy more accessible by spreading the cost over time:

1. Interest-Free Loans: Several energy providers and financial institutions offer interest-free loans specifically for solar panel installations. These loans typically have flexible repayment terms and allow you to pay monthly, making it easier to afford the installation without incurring additional interest costs.
2. Solar Panel Financing from Installers: Some solar panel installation companies offer their own financing options, including interest-free loans or affordable payment plans. 
3. Solar Together Scheme: While not a loan, the Solar Together group-buying scheme offers discounted prices on solar panel installations. Some participating installers may also offer financing options, including interest-free periods, to make the upfront costs more manageable.

How to Apply for Solar Panel Grants and Funding

To apply for solar panel grants and funding in the UK, follow these steps:

1. Check Eligibility: Research government schemes like the Energy Company Obligation (ECO4) or local council grants for financial support. Visit their websites for details.
2. Explore Financing: Some solar companies offer interest-free loans or payment plans. 
3. Consider the Solar Together Scheme: This group-buying initiative offers discounted solar panel installations through local councils.
4. Prepare Documentation: Gather necessary documents like proof of income and property details for your application.
5. Apply: Submit your application directly through the respective program or contact solar installers for guidance.

FAQ

Are solar panels worth the investment?

Yes, solar panels are often a worthwhile investment. While the upfront cost can be significant, solar panels can lower your energy bills over time, and with government incentives, interest-free loans, and the Smart Export Guarantee (SEG), the financial benefits are enhanced. 

Can I get free solar panels from the government?

The UK government does not provide free solar panels, but there are schemes like the Energy Company Obligation (ECO4) that offer subsidised solar panel installations for low-income and vulnerable households. These schemes help reduce the cost, but homeowners must meet specific eligibility criteria to qualify for free or heavily subsidised installations.

How does the Smart Export Guarantee (SEG) work?

The Smart Export Guarantee (SEG) allows homeowners with solar panels to sell the surplus electricity they generate back to the grid. Energy suppliers must pay for the renewable electricity you export, typically offering rates between 3p and 20p per kWh. This can generate an additional income stream, depending on how much surplus energy you produce.

What financing options are available for homeowners?

Homeowners can access various financing options for solar panel installations, including interest-free loans, payment plans from solar installers, and energy efficiency loans from banks. These options allow homeowners to spread the cost of installation over time, making solar energy more affordable without the need for large upfront payments.

What tax benefits are available for solar panel installations?

In the UK, there are no direct tax credits for solar panel installations, but the removal of VAT on solar panel installations until 2027 significantly reduces costs. Additionally, homeowners can benefit from the Smart Export Guarantee (SEG), which allows them to earn money from surplus energy generated.
