As energy costs rise and the UK heads towards its 2050 net-zero carbon emissions target, solar panels are becoming a more popular choice for homeowners looking to cut bills and go green. But the upfront cost of solar panel installation can be a big barrier. So, are government grants for solar panels available in the UK?
The good news is, yes, there are options to help offset these costs, including schemes that offer free solar panels for eligible households. In this guide, we’ll cover the latest solar panel grants, funding and alternative financing options for 2025 so you have all the information you need to make an informed decision.
Yes, you can get free solar panels through specific government-backed schemes, particularly if you’re a low-income household. One of the main schemes is the Energy Company Obligation (ECO4) scheme which runs until March 2026. ECO4 is designed to improve energy efficiency in homes across England, Scotland and Wales, targeting those in fuel poverty or with low energy ratings. Under this initiative, qualifying households can get fully funded solar panel installations, meaning no upfront costs for the equipment or labour. Check your eligibility here
For ECO4 you typically need to meet one of these criteria:
Receiving Benefits: Households on means-tested benefits like Universal Credit, Pension Credit or Child Tax Credit often qualify.
Low Income: Even if you’re not on benefits, a household income below £31,000 may qualify under the Local Authority Flexibility (LA Flex) rules, depending on your local council’s criteria.
Poor Energy Efficiency: Your home must have an Energy Performance Certificate (EPC) rating of D, E, F or G, meaning it’s one of the least energy efficient properties.
The process starts with an eligibility check – often a quick online form or a call to your energy supplier. If approved, a surveyor will assess your home to confirm suitability, followed by a free installation. At Wow Energy, we regularly update our insights on schemes like ECO4 to help homeowners navigate these opportunities.
While ECO4 is the main route for free solar panels, regional schemes offer more options:
Welsh Government Warm Homes Nest Scheme: Available in Wales, this scheme provides free energy-saving upgrades, including solar panels, to households on income-related benefits or living in low-efficiency homes. Find out more here
Home Upgrade Grant (HUG2): Running from April 2023 to March 2025, HUG2 offers up to £10,000 for off-grid, low-income households in England to install solar panels and other upgrades.
These schemes vary by location and eligibility, so check with your local authority or government websites for the latest information.
If you don’t qualify for free solar panels, don’t worry – there are still ways to reduce the cost of going solar in the UK. The government and private sector offer incentives and financing options to make solar energy more accessible to a wider audience.
Zero VAT on Solar Panels (2022–2027)
Since April 2022, the UK government has removed VAT on solar panel purchases and installations, a relief that will last until March 2027. This applies to England, Scotland and Wales, saving up to £2,000 on a typical 4kW system. For homeowners, this means instant savings with no application process – your installer, like the experts at Wow Energy, will apply the 0% VAT automatically at the point of sale.
Smart Export Guarantee (SEG): Earn Money from Your Panels
Introduced in January 2020, the Smart Export Guarantee (SEG) isn’t a grant but a financial incentive that lets you earn money by selling surplus solar energy back to the grid. Available across England, Scotland and Wales (but not Northern Ireland), SEG requires energy suppliers with over 150,000 customers to offer export tariffs. Rates vary – from 1p to 24p per kWh – potentially earning you £80 to £200 per year on a 4kW system, depending on your usage and tariff.
To participate you’ll need:
• A solar PV system (up to 5MW capacity).
• An MCS-certified installation.
• A smart meter to track exports.
This scheme complements the bill savings from solar energy, which can be up to £730 per year for an average household, making it a great long-term investment.
Solar Together: A group-buying scheme run by local councils across the UK to reduce solar panel costs through bulk purchasing. Homeowners and renters in participating areas can join and get 10-25% off standard rates. Check your council’s website to see if Solar Together is available in your area.
Beyond funding, solar panels offer:
Energy Bill Savings: Generate your own electricity and reduce your reliance on expensive grid power.
Environmental Impact: Reduce your carbon footprint with clean, renewable energy.
Energy Independence: Protect yourself from volatile energy prices.
The UK is committed to net zero and the £6.6 billion Warm Homes Plan (launching in 2025) means solar will become more mainstream. Not all households qualify for free installations but the combination of grants, tax relief and export earnings makes solar a good option.
Apply for a solar panel grant depends on the scheme:
ECO4: Visit the ECO4 website or contact your energy supplier. Provide proof of benefits or income and a recent utility bill. For LA Flex, you may need a council tax bill and income evidence (e.g. payslips or P60).* HUG2: Check with your local authority for details as funding is area specific.
Warm Homes Nest: Apply via the Welsh Government’s Nest website or helpline.
Always check eligibility criteria before applying to avoid wasting time. At Wow Energy we recommend starting with a quick eligibility check—our team can guide Cheshire residents through the process.
Reports in late 2024 suggest the government will be expanding solar incentives as part of its 2030 clean energy targets. Details are pending—likely to be confirmed in the Spring 2025 spending review—but schemes like the Warm Homes Plan could open up more solar funding. Stay informed and we’ll keep you up to date on the latest developments for UK homeowners.
Whether you qualify for free solar panels through ECO4 or opt for financing with zero VAT and SEG benefits, 2025 is the perfect time to invest in solar. The combination of government support and falling installation costs makes it more affordable than ever to save on your bills and carbon footprint.
