Grants and Subsidies for Installing Solar Panels

Three professionals in hard hats walk through a solar panel field, appearing to discuss planning or funding opportunities. The context suggests a review of site development possibly supported by grants and subsidies.

The transition to clean energy is no longer a matter of future planning – it’s a pressing necessity. In the UK, more homeowners, businesses, and community organisations are turning to solar energy as a reliable, sustainable, and cost-effective alternative to fossil fuels. However, the initial cost of installing solar panels remains one of the main barriers to adoption. That’s where grants and subsidies come into play, offering a practical way to make renewable energy systems more accessible to a wider audience.

Thanks to a combination of government support schemes, local council initiatives, and evolving energy policies, there are various grants and subsidies available across the UK that can help reduce the upfront cost of going solar. These incentives vary by region, household income, type of property, and the kind of system you intend to install, but they all share one goal: promoting a cleaner and more energy-independent future.

In this article, we’ll explore the key options for grants and subsidies available in the UK, explain who can access them, what steps to follow, and what considerations to take into account before making the switch. Whether you’re a homeowner looking to cut energy bills or a business seeking to reduce your carbon footprint, understanding the available support is crucial to making solar energy a realistic and rewarding investment.

What Are Grants and Subsidies for Solar Power?

When we talk about grants and subsidies in relation to solar panels, we refer to financial incentives that help lower the cost of purchasing and installing a solar photovoltaic (PV) system. These incentives might be offered in the form of one-off payments, tax relief, zero-interest loans, or tariff-based payments for electricity generated.

The purpose of these schemes is to encourage wider adoption of solar energy by reducing the economic barrier of entry. They not only support the UK’s transition to net zero by 2050, but they also help households and businesses mitigate the impact of rising energy prices.

The types of support available can range from national-level programmes to localised council grants, and they often come with specific eligibility criteria. Some are geared towards low-income households or properties that meet certain efficiency standards, while others are open to anyone installing a qualifying solar PV system.

National Solar Incentives and Government Support

At the national level, the UK has gone through several iterations of solar incentives. While some of the early schemes – like the Feed-in Tariff (FIT) – are no longer open to new applicants, other opportunities have emerged in their place.

The most prominent support currently in place is the Smart Export Guarantee (SEG), which was introduced in January 2020. This scheme requires licensed electricity suppliers to offer payments to small-scale solar energy producers for the surplus electricity they export to the grid.

Smart Export Guarantee (SEG)

Under SEG, if your solar PV system produces more electricity than you use, your energy supplier will pay you for the excess. The rates and terms vary between suppliers, but this provides a meaningful way to offset costs over time and improve the return on your solar investment.

To qualify, your system must be installed by a Microgeneration Certification Scheme (MCS) accredited installer, and it must include a smart meter capable of measuring export amounts accurately.

SEG is not a grant in the traditional sense, but it acts as a long-term financial benefit for solar owners by turning your home into a mini power station.

Local and Regional Grants and Subsidies

In addition to national-level schemes, many local councils and devolved administrations offer their own grants and subsidies for installing solar panels. These can vary widely in scope, availability, and eligibility.

Scotland

In Scotland, homeowners can benefit from the Home Energy Scotland Loan, which offers interest-free loans of up to £6,000 for solar PV systems, with cashback available for certain technologies. This scheme is especially attractive as it reduces the need for upfront capital and can be combined with other efficiency improvements.

Wales

The Welsh Government has previously supported renewable energy adoption through the Nest scheme, which focuses on improving energy efficiency and reducing fuel poverty. While not always directly tied to solar panels, these schemes often include options for renewable installations where they significantly improve household sustainability.

Northern Ireland

In Northern Ireland, solar incentives are more limited, but households can explore options through local council programmes and community grants. Some credit unions and cooperative banks also offer green loans specifically tailored for renewable energy improvements.

Local Councils in England

Across England, many local authorities have initiated their own support schemes. These might include partial grants, zero-interest loans, or bulk purchase initiatives that reduce the cost through collective procurement. Councils such as Camden, Brighton & Hove, and Bristol have led successful schemes encouraging solar adoption at a community level.

Because these programmes change frequently and are highly localised, it’s always worth checking your local council website or contacting their energy efficiency or sustainability team directly.

Who Can Apply for Solar Grants and Subsidies?

Eligibility for grants and subsidies in the UK largely depends on several factors, such as:

  • Type of property: Residential homeowners, tenants (with landlord consent), and businesses may be eligible.

  • Income level: Some schemes are means-tested, prioritising low-income households or those in fuel poverty.

  • Energy performance: Properties that meet or improve their Energy Performance Certificate (EPC) rating may be favoured.

  • Installer certification: You typically need to use an MCS-certified installer to qualify for most schemes.

  • Installation purpose: Some subsidies are available only for off-grid systems, while others require grid connection.

Always review the specific criteria for each grant or scheme before applying. Consulting with a certified solar installer or an energy advisor can also help clarify which options best suit your needs.

The Role of MCS-Certified Installers

Using an installer accredited by the Microgeneration Certification Scheme (MCS) is crucial for both system performance and eligibility for grants and subsidies. MCS certification ensures that your installer meets quality and safety standards, and it’s typically a requirement for any financial support scheme in the UK.

Certified installers are also familiar with the documentation and compliance needed for grant applications, and many will help guide you through the process. This added support can save you time, avoid delays, and improve your chances of securing financial incentives.

Moreover, MCS certification often extends to the equipment itself, so make sure both the installer and the solar PV system components (like inverters and panels) are MCS-approved.

How Much Can You Save?

The cost of a typical domestic solar panel system in the UK ranges from £4,000 to £8,000, depending on system size, battery storage, and installation complexity. With grants and subsidies, plus earnings from the Smart Export Guarantee, the effective cost can be significantly reduced.

For example, if you access an interest-free loan of £6,000 through Home Energy Scotland and earn £150 to £300 per year from SEG payments, your system could pay for itself in 7 to 10 years, depending on your usage. After that, the savings continue, and with panels typically lasting 25 years or more, the long-term benefit is considerable.

Additional savings come from reducing or nearly eliminating your electricity bill. In homes with battery storage, reliance on the grid can be minimised further, particularly during spring and summer.

Key Steps Before Applying

Before applying for grants and subsidies, it’s advisable to take the following steps:

  1. Assess your electricity usage to determine the right system size.

  2. Check your roof condition and orientation—ideally south-facing, unshaded, and in good repair.

  3. Request multiple quotes from MCS-certified installers.

  4. Research all national and local schemes for financial support.

  5. Make sure your property meets energy efficiency requirements, especially if applying for schemes that involve other insulation or heating upgrades.

Environmental and Social Benefits

Installing solar panels supported by grants and subsidies doesn’t only reduce your energy bills—it also has a meaningful environmental impact. Solar energy systems significantly lower your carbon emissions, helping the UK reach its legally binding climate targets.

On a social level, government-backed schemes often prioritise households in fuel poverty, offering access to clean energy where it’s needed most. Community solar programmes also empower neighbourhoods to collectively invest in renewable energy, creating a more equitable and sustainable energy future.

Additionally, increased demand for solar installations supports job creation in green industries, helping drive a just transition to a low-carbon economy.

The Future of Solar Incentives in the UK

The outlook for grants and subsidies in the UK is promising, especially with continued government emphasis on reaching net zero by 2050. As part of this commitment, we’re likely to see more support for energy-efficient homes, integration of solar with heat pumps and electric vehicle charging, and expanded community energy schemes.

Programmes like Green Home Finance and updates to the Energy Company Obligation (ECO) suggest a future where low-carbon home improvements, including solar, become the norm rather than the exception.

Keeping informed about policy changes and upcoming schemes is essential, as the funding landscape evolves rapidly.
