Solar electricity grants explained

Installing solar panels can significantly reduce your energy bills and carbon footprint, but the initial cost often feels prohibitive. Various UK government-backed schemes and incentives exist to help homeowners reduce this upfront investment, making solar electricity more accessible.

Fuse Energy is an energy supplier that offers competitive Smart Export Guarantee (SEG) tariffs once your solar panels are installed. We provide smart tools to help you monitor and manage the electricity you generate and export. Click here to switch to Fuse Energy today.

Understanding solar electricity grants

Solar electricity grants are financial incentives designed to encourage the adoption of solar photovoltaic (PV) systems in the UK. These schemes aim to reduce the initial cost of installation, not to provide 'free' solar panels, by offering financial support to homeowners. The goal is to accelerate the transition to renewable energy, decrease carbon footprints, and lower household energy expenditures.

What are solar panel grants?

Solar panel grants are financial aid packages from governmental bodies, local authorities, or energy companies. They help offset the cost of purchasing and installing solar panels, making the technology more affordable. These grants are crucial for homeowners looking to invest in renewable energy without facing the full financial burden upfront.

Why consider solar panel funding?

Beyond the immediate financial relief, securing funding for solar panels offers a pathway to long-term savings and energy independence. Grants help make the investment more manageable, allowing you to benefit from reduced electricity bills and contribute to a more sustainable energy system. The availability of such funding addresses the core problem many UK homeowners face: the perceived high initial investment in solar technology.

Key UK solar grant schemes

Several national and regional schemes are available to support homeowners in installing solar panels. Eligibility criteria vary, so it's important to check the specifics for each.

The Energy Company Obligation (ECO4) scheme

The ECO4 scheme is a government energy efficiency initiative in Great Britain, administered by Ofgem, that focuses on improving the energy efficiency of low-income and vulnerable households. It can potentially cover a significant portion of solar panel installation costs for eligible homeowners. This scheme aims to tackle fuel poverty and reduce carbon emissions by improving the energy efficiency of the least efficient homes in the UK. The ECO4 scheme is scheduled to run until 31 December 2026.

Regional and local authority grants

Beyond national schemes, local authorities and regional bodies sometimes offer specific grants or incentives for solar panel installations. For example, homeowners in Scotland might find support through Home Energy Scotland, which offers advice and grants for energy-efficient home improvements. These regional schemes often have specific eligibility criteria based on location and household income, so it's worth checking what's available in your area.

The Smart Export Guarantee (SEG)

The SEG is a government-backed initiative that allows homeowners to earn money by exporting surplus electricity generated by their solar panels back to the National Grid. It's a key financial incentive for solar panel owners in the UK.

What the SEG is and how it works

The SEG mandates that licensed electricity suppliers offer a tariff to pay small-scale low-carbon generators for electricity exported to the grid. This means that if your solar panels generate more electricity than you use, you can sell the excess back to an energy supplier. The SEG was launched on 1 January 2020, replacing the previous Feed-in Tariff (FiT) scheme.

Eligibility for SEG tariffs

To be eligible for an SEG tariff, your solar panel system must have an installed capacity of up to 5 MW (megawatts). Your installer must be certified under the Microgeneration Certification Scheme (MCS) or an equivalent scheme, ensuring your installation meets high standards. You also need a smart meter that can send half-hourly readings to your energy supplier, as this accurately measures the electricity you export. If you don't have one, your SEG supplier can often arrange a smart meter installation for you.

Maximising your SEG earnings

To get the most out of the SEG, compare the tariffs offered by different energy suppliers. Rates can vary significantly, so shopping around is crucial. Some suppliers offer higher rates for customers who also buy their electricity from them. Monitoring your energy generation and consumption can also help you understand how much surplus electricity you're exporting, allowing you to optimise your usage and maximise your earnings.

Additional financial incentives for solar

Beyond grants and export tariffs, other financial benefits make solar panel installation an attractive investment for UK homeowners.

Zero-rated VAT on solar panel installation

The VAT on the installation of energy-saving materials, including solar panels, is currently zero-rated for residential properties in Great Britain. This significantly lowers the upfront cost of installing a solar electricity system, making it more affordable for homeowners. This VAT relief applies to the supply and installation of solar panels, as well as other energy-saving measures, and is set to last until 31 March 2027, after which it will revert to a 5% rate.1

Potential for energy bill savings

A typical UK home uses around 2,500 kWh of electricity per year, according to Ofgem's medium Typical Domestic Consumption Value (TDCV), effective from 1 July 2026. By generating your own electricity with solar panels, you can significantly reduce the amount of power you need to buy from the grid, leading to substantial savings on your energy bills. The extent of these savings depends on your household's electricity consumption, the size and efficiency of your solar system, and how much of the generated electricity you use directly. Understanding your energy bill can help you track these savings.

Eligibility and application process

Navigating the eligibility criteria and application process for solar electricity grants can seem complex, but breaking it down into steps makes it more manageable.

General eligibility criteria

Eligibility for solar panel grants and incentives typically depends on several factors:

• Property ownership: Most schemes are for homeowners.
• Household income: Some grants, like ECO4, are specifically for low-income households.
• Property type and energy efficiency: Older, less efficient homes might qualify for more support.
• System specifications: The size and type of your solar panel system may need to meet certain standards, such as the 5 MW capacity limit for SEG.
• Installer certification: Installers must be MCS certified to ensure eligibility for most grants and the SEG.

Step-by-step application guide

1. Research available schemes: Identify grants and incentives applicable to your location and circumstances.
2. Check eligibility: Carefully review the specific criteria for each relevant scheme.
3. Obtain quotes: Get quotes from several MCS-certified solar installers.
4. Apply for grants: Submit applications for the grants or schemes you qualify for.
5. Arrange installation: Once approved, schedule the installation of your solar panels by an approved installer.
6. Apply for SEG tariff: After installation, apply for an SEG tariff with an energy supplier like Fuse Energy. You will need your export MPAN; if you don't have one, Fuse can help generate it. For more information on this, you can read our article on what is an MPAN.

Finding MCS certified installers

MCS certification is crucial for ensuring your solar panel installation meets industry standards and for qualifying for schemes like the SEG. You can find MCS-certified installers through the MCS website, which provides a searchable database of approved contractors. Always verify an installer's certification before committing to any work.
