Solar Panel Grants and Funding in the UK: Everything You Need to Know

Installing solar panels is one of the most effective ways to cut your energy bills, boost your property’s value, and reduce your carbon footprint — all while gaining more control over your energy use. But for many UK homeowners, the upfront cost of solar installation is a common barrier. Fortunately, a range of government grants and funding schemes now make solar installation far more affordable. This guide breaks down the latest UK solar panel incentives, who’s eligible, and how to apply so you can start saving on energy costs and move closer to energy independence.

Key Takeaways

• Government grants and local council schemes can reduce the upfront cost of solar panels.
• Initiatives like ECO4, SEG, and Home Energy Scotland make solar funding accessible in many parts of the UK.
• VAT has been removed on solar installations until 2027, helping lower costs even further.
• Combining solar panels with other energy-efficient upgrades enhances savings and sustainability.

Why the UK Government Offers Solar Panel Initiatives

The UK government is focused on reducing carbon emissions and accelerating the transition to a cleaner, more resilient energy system. Solar panel grants are a core part of this strategy.

These initiatives are designed to make renewable energy more affordable and widespread, helping households and businesses take part in the shift. They support the UK’s legally binding commitment to reach net-zero emissions by 2050 while also reducing reliance on fossil fuels and strengthening long-term energy security.

Solar Panel Grants and Funding Available in the UK

Several government schemes are available to help offset the cost of solar panel installation. While eligibility varies, many are designed to assist homeowners, landlords, and businesses looking to improve energy efficiency.

The Energy Company Obligation (ECO4) Scheme

The Energy Company Obligation (ECO4) scheme is a government-backed initiative that helps low-income and vulnerable households access free or subsidised energy-efficient home improvements, including solar panel installation. It’s designed for properties with poor energy performance (typically rated D, E, F, or G on an Energy Performance Certificate). The ECO4 grant is available in England, Scotland, and Wales. It is currently unavailable in Northern Ireland.

Both homeowners and tenants in private or social housing may be eligible if they receive certain government benefits, such as Universal Credit, Pension Credit, or Income Support.

In some cases, households that don’t receive benefits but are facing high energy costs can still qualify through the ECO4 Flex scheme, which is administered by some local councils.

To apply, contact your local council to find out if they’re taking part in the Energy Company Obligation scheme, or contact an energy supplier directly. You can find the contact details of suppliers who are taking part in the scheme on the Ofgem website.

Warm Homes Grant

Set to launch in 2025, the Warm Homes Plan will provide funding for energy-efficient home upgrades, including new solar panel installations, for low-income households. Thousands of families are expected to benefit from improvements such as insulation, clean heating systems, and renewable technologies like solar panels and heat pumps.

Eligibility details will be confirmed closer to the launch, but the programme is expected to focus on households with low incomes or poor energy efficiency. Local authorities are likely to manage applications, so keeping an eye on council announcements or government updates will help you stay informed when the scheme becomes available.

Smart Export Guarantee (SEG)

While not a grant, the Smart Export Guarantee (SEG) is a government-backed initiative that encourages the adoption of solar energy by offering a financial return on the electricity you export. Under this scheme, energy suppliers are required to pay for the renewable energy you generate and send back, with rates typically ranging from 3p to 20p per kWh. For instance, E.ON’s Next Export Exclusive tariff pays 16.5p per kWh, while British Gas offers 15.1p per kWh.

A typical 3.5kW solar panel system in the UK generates between 3,000 and 3,500 kWh of electricity per year. Based on average household usage, around 1,000 to 1,500 kWh could be exported — potentially earning homeowners between £150 and £225 annually at a rate of 15p per kWh.

Zero VAT on Solar Panel Installations

The UK government has scrapped VAT on solar panel installations until 2027, helping homeowners reduce upfront costs and make the switch to renewable energy more accessible. While this isn’t a grant, it’s a meaningful tax break that directly lowers the price of going solar.

Previously set at 5%, the new 0% VAT rate on solar panels and batteries can save homeowners around £250 on a typical £5,000 installation. 

​The Home Energy Scotland Grant and Loan Scheme

​The Home Energy Scotland Grant and Loan scheme offers financial assistance to Scottish homeowners aiming to enhance their property’s energy efficiency and reduce carbon emissions. Eligible applicants can receive up to £15,000 in grants: up to £7,500 for EE improvements and an additional £7,500 for installing clean heating systems like heat pumps. Homeowners in rural areas may qualify for extra funding—up to £1,500 more for each category—to address higher installation costs. ​

To be eligible, you must own and reside in the property in Scotland and plan to implement improvements recommended in an Energy Performance Certificate (EPC), Home Energy Improvement Report, or Home Renewable Selector Report. ​

Applicants can apply by contacting Home Energy Scotland by phone or online to speak with an advisor. If eligible, you’ll receive a personalised application link to submit your documents and begin the process. 

Local Authority and Regional Incentives

Beyond national schemes, many local councils across the UK provide their own solar panel incentives. These regional programmes vary by location — some offer full funding for low-income households, while others provide rebates or low-interest loans to help offset installation costs.

Checking with your local authority is a smart first step, as these tailored schemes can make switching to solar even more affordable and achievable in your area.

Interest-Free Loans & Solar Panel Funding 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: Some 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. 

Let’s Recap

Switching to solar energy is no longer out of reach for most UK homeowners. With a growing range of grants, tax incentives, and funding options now available, the upfront cost of solar panel installation can be significantly reduced. Whether you’re eligible for national schemes like ECO4, regional support from your local authority, or interest-free loans, there are more ways than ever to make your home energy-efficient and future-ready.

While the application process and availability of support vary by region and household type, doing a little research—and seeking advice from trusted providers—can unlock substantial savings. With the added benefit of long-term energy bill reductions and increased energy independence, investing in solar is a smart move for homeowners across the UK.
