Solar Panel Grants UK 2026: What You Can Actually Claim

If you’ve searched for “solar panel grants 2026” and come away more confused than when you started, you’re not alone. There’s a lot of noise online about free solar panels, and most of it either oversells what’s on offer or buries the genuinely useful schemes under sponsored ads. So here’s the straight version: what’s actually available right now, who qualifies, and what it’s worth in real money.

There isn’t a single government grant that hands every homeowner a cheque for solar panels. What there is, is a stack of separate schemes that overlap depending on your income, your property, and what you’re trying to install. Some apply automatically. Others need an application. A couple are means tested. We’ll go through each one in turn.

Solar Panel Grants UK 2026: The Full Picture

Solar panel grants in the UK for 2026 aren’t a single scheme you tick a box for, they’re a mix of automatic savings, application based funding, and tax relief that stack depending on your circumstances. Below we’ve broken down every route that’s actually live right now, starting with the one that applies to every household automatically, through to the means tested grant that can cover a full system, and the heat pump grant that pairs well alongside it:

1. Zero VAT on solar panels and batteries

This is the one that applies to absolutely everyone, no forms, no eligibility check. Residential solar panel and battery storage installations carry 0% VAT, and that’s confirmed to run until at least March 2027. On a typical system costing around £10,000, that’s roughly £1,000 to £2,000 you’re not paying compared to standard rate VAT, depending on system size and your installer’s pricing.

You don’t need to do anything to get this. Any MCS certified installer applies it automatically at the point of quoting and invoicing.

2. Smart Export Guarantee (SEG) payments

Once your panels are up and generating more than your home needs, the surplus goes back to the grid, and under the Smart Export Guarantee, your supplier has to pay you for it. Any licensed electricity supplier with more than 150,000 customers is required to offer at least one export tariff, and you can register with a different supplier for your SEG payments than the one you buy your electricity from.

Rates move around fairly often as suppliers compete for solar customers. As things stand, fixed rate tariffs from the larger suppliers tend to sit somewhere between 3p and roughly 16.5p per kWh. If you’ve got a compatible battery and you’re happy with a variable rate, some tariffs pay considerably more during peak evening hours, up into the 25 to 30p per kWh range between around 4 and 7pm. The catch with those higher rates is they usually need you to take your electricity import from the same supplier too, so it’s worth comparing the whole package, not just the headline export rate.

For a typical 4kWp system exporting around half its generation, annual SEG income usually lands somewhere between £50 and £250 a year, though it can run higher with a well matched battery and a peak rate tariff.

3. Warm Homes: Local Grant (for lower income households)

This is the closest thing to a genuine free solar panel scheme in England right now. If your household income is below roughly £36,000 a year, or you receive a qualifying means tested benefit such as Universal Credit, Pension Credit, Housing Benefit or Tax Credits, and your home has an EPC rating of D, E, F or G, you may be eligible for a fully funded package of energy efficiency improvements worth up to £15,000. That can include solar panels and battery storage alongside insulation and other upgrades.

The exact income threshold is set locally, so it does vary a bit from council to council, but £36,000 is the figure most areas use. The scheme is run through your local authority and is funded through to March 2028, though pots are allocated regionally and do run out, so it’s worth applying sooner rather than later if you think you qualify.

How to apply: contact your local council directly. In our coverage area that’s Liverpool City Council, Warrington Borough Council, Cheshire West and Chester Council, or your relevant Greater Manchester borough.

4. ECO4 (still running, despite what you may have read)

There’s a fair bit of outdated information floating around saying ECO4 ended in March 2026. It didn’t. The government extended it to 31 December 2026, and no like for like replacement has been confirmed yet, so if you’ve got a qualifying low income or you’re on a relevant benefit, it’s genuinely worth checking your eligibility now rather than waiting for a successor scheme that may take time to launch. ECO4 is funded by the larger energy suppliers and can cover solar, insulation and heating upgrades for eligible households, often working alongside the Warm Homes Local Grant rather than instead of it.

5. Boiler Upgrade Scheme: £7,500 towards a heat pump, pairs well with solar

The Boiler Upgrade Scheme gives homeowners £7,500 towards an air source heat pump (the same amount for ground source), and as of late April 2026 the rules got noticeably easier. You used to need a valid EPC showing no outstanding loft or cavity insulation recommendations before you could apply. That requirement has now been scrapped, which opens the scheme up to a lot of properties that were previously turned away on a technicality. The scheme itself has also been extended through to 2030, with a total budget of £2.7 billion.

Why it matters for solar: a heat pump running on electricity you’ve generated yourself is one of the more cost effective ways to heat a home long term. You’re not eliminating your heating costs, but you’re meaningfully reducing them, especially if your system and battery are sized with the heat pump’s daytime running in mind.

6. Enhanced Capital Allowances for businesses

This one’s for limited companies and partnerships rather than homeowners. Most commercial solar and battery installations qualify for 100% first year tax relief through Enhanced Capital Allowances, meaning the full capital cost can be deducted from taxable profit in the year you buy the system. It’s not a grant in the traditional sense, it’s a tax mechanism, but it materially changes the return on investment for a business installation.

As a rough example, a 50kWp commercial system costing £35,000 could see a company paying 25% corporation tax save £8,750 in tax, bringing the effective net cost down to £26,250. Speak to your accountant to confirm your specific situation, since eligibility depends on your company structure and tax position.

What this actually saves you in the North West

Numbers help more than percentages here. A 4kWp solar system with a 5kWh battery typically saves North West homeowners somewhere between £600 and £900 a year on electricity, depending on usage patterns and how much of your generation you’re able to use yourself rather than export. Add SEG income on top and most households see payback somewhere in the 7 to 11 year range, with the system continuing to generate savings well beyond that, since panels are commonly warrantied for 25 years.

Liverpool, Warrington, Cheshire and Greater Manchester all receive a reasonably similar amount of usable solar irradiance, generally in the range of 850 to 950 kWh per installed kWp annually. That’s noticeably less than the South East of England gets, but it’s still more than enough to make the financial case work, particularly as electricity prices have continued to climb.

Choosing an installer: don’t skip this part

None of the above matters much if the installation itself is done badly or by someone who isn’t properly accredited. A few things are worth checking before you sign anything with any installer, anywhere in the country, not just with us.

• MCS certification. This isn’t optional if you want to access the Smart Export Guarantee or most of the grants above. Without it, your exported electricity goes unpaid and most schemes simply won’t accept your application.
• NICEIC accreditation or equivalent. Solar work involves high voltage DC wiring, and your installer needs to correctly notify your Distribution Network Operator under G98/G99 regulations, particularly for systems over 3.68kW.
• An actual site survey before you get a quote. Roof orientation, shading, structural condition and your existing electrical setup all affect what’s realistic. If a company quotes you a price and a savings figure without sending someone to look at your roof, treat that figure with real scepticism.
• Warranty terms in writing. Twenty five years on panels and ten years on the inverter is the industry standard from reputable manufacturers. Anything shorter is worth questioning.
• Who’s actually doing the work. Ask whether the engineers on site are directly employed or subcontracted. It affects accountability if something needs fixing after the job’s done.
