Solar panels decrease electricity bills by hundreds of pounds every year. So what is the problem? Installation costs thousands upfront. But there’s a way around this. Government schemes can cover the full cost or give you serious discounts on solar panel installation.

This guide walks through all the solar panel grants UK homeowners can claim right now. You’ll learn who qualifies, what each scheme offers, and how to apply.

What Solar Panel Funding Is Available?

Several government programs help UK households to install solar. Each scheme works differently and targets various groups of people. Let’s break down what’s out there.

ECO4 Grants Scheme

ECO4 stands out as the biggest source of solar panel grants UK families can access. Running through to 2026, this scheme pays for complete solar installations at zero cost to eligible households.

How it works:

Big energy companies must help reduce UK carbon emissions by law. They do this by funding energy improvements in people’s homes. Solar panels are one of the upgrades they’ll pay for.

Who gets ECO4? 

People claiming benefits get priority. Also, if your home has an energy rating of D, E, F, or G on its EPC certificate, you’re in the target group. The worse your home’s energy efficiency, the stronger your application. Getting solar panels through ECO4 means no money out of your pocket. The energy company covers everything, panels, installation, the lot.

Smart Export Guarantee

The Smart Export Guarantee works differently from other solar panel grants UK programs. It doesn’t pay for installation. Instead, it pays you for the electricity your panels produce. Once you’ve got solar panels working, they generate power all day. Sometimes you’ll make more than your home uses. That extra electricity goes back into the national grid. Energy companies pay you for it.

Payment rates vary between companies. Some offer 15p per unit of electricity. Others pay less. But whichever company you pick, you’re earning money from sunshine hitting your roof. You need panels installed first before SEG kicks in. Think of it as ongoing income that helps recover your installation costs faster.

0% VAT on Solar Panels

Since April 2022, solar panel installation carries no VAT. This applies to everyone getting panels fitted, regardless of income or circumstances. Before the change, you’d pay 5% VAT on the whole job. On a £6,000 installation, that’s £300 extra. Now that £300 stays in your pocket.

This isn’t a grant payment. Nobody gives you cash. But you save money on the total bill, which amounts to the same thing. Every household getting solar panels benefits from this automatically.

Warm Homes Plan

The Warm Homes Plan bundles multiple energy improvements together. Solar panels often come as part of a bigger package that might contain insulation, new heating systems, and other upgrades. This plan mainly focuses on households struggling with energy costs. Low-income families get priority. People living in the coldest, most inefficient homes also qualify more easily.

What makes this different? 

You might get solar panel grants UK, UK funding, plus other improvements, all at once. Your home gets a complete energy makeover rather than just one upgrade. Everything works together to cut your bills as much as possible. The plan started in 2025 and has limited funding. First-come, first-served applies here.

How the Application Process Works

Getting solar panel grants in the UK follows a clear path. The exact steps vary slightly by scheme, but the basics stay the same across all programs. Start by checking eligibility. Each scheme has its own criteria. Some look at the benefits you receive. Others check your income or your home’s current energy rating. Know where you stand before going further.

Next, find an approved installer. This matters more than you’d think. Random solar companies can’t access grant funding. You need installers registered with the specific scheme you’re applying through. These approved companies handle all the paperwork and know exactly what’s required.

An assessment comes next. Someone visits your property to check if solar panels will work. They look at your roof’s direction, angle, and condition. They check for shade from trees or nearby buildings. Not every roof suits solar panels, so this step filters out unsuitable properties.

If your home passes the assessment, installation gets scheduled. Most jobs take one or two days, depending on system size. After that, you’re generating your own electricity and watching your bills drop month after month.

Who Can Get These Grants?

Different schemes have different rules. Understanding who qualifies for each solar panel grants UK program helps you pick the right one to apply for.

ECO4 mainly serves benefit recipients. Universal Credit, Pension Credit, and Child Tax Credit etc these are the main benefits that qualify you. There’s also the LA Flex route. If your home has a D-G energy rating but you don’t claim benefits, your local council can still refer you to ECO4 based on low income or other factors.

The 0% VAT rule is universal. Everyone getting solar panels installed pays zero VAT. No forms to fill, no means testing. The discount applies automatically.

Warm Homes Plan eligibility centers on fuel poverty and low incomes. If heating your home properly is a struggle financially, this scheme targets you specifically. Households in the least energy-efficient properties also get priority.

Smart Export Guarantee is the most open. Anyone with solar panels and a smart meter can sign up. Your income doesn’t matter. Whether you own or rent doesn’t matter. You just need panels producing electricity and the ability to export surplus back to the grid. Mainly, the Installation requires MCS (or equivalent) certification, and a smart meter with half-hourly export readings capability.

Don’t Delay – Check If You Qualify Now

None of these schemes runs forever. ECO4 definitely ends in 2026. Warm Homes Plan funding gets allocated until it runs dry. Once the money’s gone, you wait for the next funding round – which might be months or years away. Every month you delay means another month of paying full electricity prices. If you qualify for free or heavily discounted solar panels, waiting makes no financial sense.

Checking eligibility takes minutes, not hours. You fill in basic details about your property, household, and income. The form tells you straight away what you might qualify for. Simple as that. Read our blogs to get the latest news and all the required information about schemes.

What Solar Panels Actually Do For You

Why do solar panel grants UK schemes even exist? Because solar energy delivers real benefits to households and the environment. Here’s what changes when panels go on your roof.

Electricity bills fall dramatically. The average household saves £300-500 yearly. Heavy electricity users during daylight hours save even more. Some households cut their bills by two-thirds. Grid dependency drops. Sunny days mean your panels power your home completely. You buy nothing from energy companies during those hours. Cloudy days still generate electricity, just less of it. Extra income arrives through the Smart Export Guarantee. Surplus electricity you don’t use gets sold automatically. This creates a second income stream that continues year after year. 

Carbon footprint shrinks. Every unit of electricity your panels generate is one less unit produced by burning gas or coal. You’re directly reducing carbon emissions just by having panels on your roof.

Conclusion

Solar panel grants UK are designed to make renewable energy accessible. Through initiatives like ECO4 and the Warm Homes Plan, alongside 0% VAT on installations, Solar panel grants UK opportunities provide multiple routes for households to cut costs dramatically or even eliminate them entirely.
