Solar Incentives: Making the Switch to Solar More Affordable

28th Aug 2025

Installing solar panels is one of the most effective ways to reduce your energy bills and cut your home’s carbon footprint. While many homeowners are attracted to the long-term savings and environmental benefits, the upfront cost can feel daunting. Fortunately, there are a range of incentives in the UK designed to make solar more affordable. These include national schemes, council-led programmes, and ongoing payments for the electricity you export back to the grid.

In this guide, we will break down the main solar incentives available today, focusing on how they work, who can benefit, and the real-world advantages they bring.

Local Authority Flex (LA Flex)

LA Flex is part of the Energy Company Obligation (ECO) scheme, but with a key difference: local councils can set their own eligibility criteria. This means they have the flexibility to extend support to households that might not qualify under the standard ECO rules.

For example, you may not meet the usual low-income or benefit-based requirements but could still be considered if your home is hard to heat, you have high energy bills, or someone in your household is vulnerable to cold conditions.

Under LA Flex, funding can be used for a range of energy efficiency improvements, and this can include solar PV installations. For qualifying homeowners, this could mean getting solar panels installed for free or at a significantly reduced cost, often as part of a wider package of home energy upgrades.

The main benefit is that it opens the door for more households to access funding that would otherwise be out of reach. Every council has slightly different rules, so it is worth checking your local authority’s policy.

ECO4 (Energy Company Obligation Phase 4)

ECO4 is the latest phase of the government-backed Energy Company Obligation scheme, running from 2022 to 2026. It requires larger energy suppliers to fund energy-saving measures in homes that are receiving income related support or occupied by vulnerable residents.

Like LA Flex, ECO4 can fund a variety of improvements including insulation, heating upgrades, and renewable technologies such as solar PV systems. For those who qualify, the installation is fully funded, meaning there is no upfront cost.

This scheme is particularly valuable for households struggling with rising energy costs, as it tackles both the efficiency of the home and its ability to generate clean, free electricity. If your property meets the criteria, ECO4 could remove the financial barrier to going solar entirely.

Smart Export Guarantee (SEG)

While LA Flex and ECO4 help with the cost of installing solar, the Smart Export Guarantee is about rewarding you for the electricity you generate. Introduced in 2020 to replace the old Feed-in Tariff, the SEG requires licensed electricity suppliers with more than 150,000 customers to offer payment for surplus renewable electricity you export to the grid.

There is no fixed national rate, so it pays to shop around. Some suppliers offer higher rates per kilowatt-hour than others, and these can be fixed or variable. Payments are made based on accurate readings from an approved meter, ensuring you are rewarded for every unit you send back to the network.

Even though the rates are generally lower than what you pay to buy electricity from the grid, the SEG provides an extra income stream that helps improve the return on your investment in solar panels. Over time, these payments can add up to hundreds of pounds, further shortening the payback period.

Other Incentives and Savings

In addition to the main schemes, there are other ways to make solar more affordable:

  • Zero or reduced VAT – Until 2027, solar panels and certain other energy-saving materials are eligible for zero VAT on installation in the UK, cutting the total cost of your project.

  • Local council schemes – Some councils run their own group-buying or subsidy programmes to encourage residents to go solar at a reduced rate.

  • Energy bill savings – While not technically an incentive, the savings on your electricity bills start from day one and build year after year with solar.

Why These Incentives Matter

For many households, the main hesitation about solar is the upfront price tag. Incentives such as LA Flex and ECO4 can remove that obstacle completely for qualifying homes. Even if you are funding your installation privately, the Smart Export Guarantee and VAT savings reduce your ongoing costs and improve your return on investment.

Together, these schemes make solar accessible to a wider range of homeowners, from those looking for long-term bill reductions to those needing urgent help with high energy costs. They also support the UK’s broader goal of reducing reliance on fossil fuels and cutting greenhouse gas emissions.

Taking the Next Step

If you are interested in installing solar panels, the first step is to check which incentives you might qualify for. This can involve:

  1. Contacting your local council to see if LA Flex is available in your area and whether you meet their criteria.

  2. Checking your eligibility for ECO4, which may require a formal assessment of your home’s energy efficiency.

  3. Comparing Smart Export Guarantee rates from different suppliers to ensure you get the best deal once your system is installed.

Final Thoughts

Solar incentives are there to make the transition to renewable energy more attainable for UK homeowners. Whether through upfront funding, reduced installation costs, or ongoing payments for exported electricity, these schemes can make a significant difference to the affordability and long-term value of your system.

By taking advantage of the options available, you can enjoy lower bills, a smaller carbon footprint, and greater energy independence. If you are ready to explore your eligibility and see how much you could save, now is the perfect time to start.
