There is no single universal solar panel grant available to every UK homeowner in 2026 — but there are real schemes open right now that can cut your costs significantly, and two firm deadlines approaching that are worth knowing before you do anything else. This guide cuts through the outdated articles and tells you exactly what you can still claim, before which date, and what's coming next.
What solar panel grants are available in the UK in 2026?
The honest picture is that solar funding in 2026 is means-tested for the best deals — free or fully funded panels are mainly available to lower-income households. But there are also cost reductions open to every homeowner, regardless of income. Here are the four main routes:
- ECO4 — free installations for qualifying low-income homes, closing 31 December 2026
- Warm Homes: Local Grant — the ECO4 successor for eligible low-income owner-occupiers in England, running to March 2028
- 0% VAT on solar — cuts your installation bill automatically, open to every homeowner until 31 March 2027
- Smart Export Guarantee (SEG) — not a grant, but a government-backed right to earn money by selling spare electricity back to the grid
A further scheme — a 0% interest consumer loan open to all homeowners — is expected from 2027. More on that below.
Is ECO4 still available for solar panels?
Yes, but time is running out. Ofgem-administered ECO4 runs until 31 December 2026, and the government has confirmed there will be no ECO5 successor. The Warm Homes Plan takes over from 2027.
ECO4 is a regulatory obligation on large energy suppliers — companies like British Gas, E.ON, Octopus and OVO are required to fund energy improvements in eligible homes. You apply through your energy supplier, not the government directly.
There is one important catch that many articles miss: under ECO4, solar PV is only funded as a heating measure. That means it is generally limited to homes with electric heating or a heat pump — not homes on mains gas. Solar is also typically offered alongside other measures such as insulation rather than as a standalone installation.
To qualify, you usually need to be receiving a means-tested benefit (such as Universal Credit, Pension Credit, or income-based ESA) and have a home with an EPC rating of D–G. Where a household does qualify, ECO4 can cover 100% of the installation cost.
The practical warning: funding is first-come, first-served, and waiting lists are growing as the scheme approaches its end. Processing from application to installation typically takes 6–12 weeks, so if you think you qualify, apply now rather than waiting. See our detailed guide to ECO4 solar panel eligibility before December 2026 for the full criteria.
What is the Warm Homes Local Grant, and can I get solar panels through it?
The Warm Homes: Local Grant is the live successor to ECO4 for low-income owner-occupiers and private renters in England. Unlike ECO4, it is funded directly by government (not energy suppliers), with £500 million allocated to run from April 2025 to March 2028.
Solar panels have been one of the most popular measures funded under the scheme. To be eligible, your home generally needs an EPC rating of D–G and a household income under £36,000. The scheme is run by local councils, so availability and the exact process vary by area — your council contacts you after an eligibility check to arrange a home survey. You cannot simply request solar panels; the assessor recommends the most suitable measures for your home.
The scheme only runs in England. If you live in Wales, the NEST scheme offers equivalent support for eligible households. Scotland and Northern Ireland have their own routes — check the relevant devolved administration for up-to-date details.
One honest caveat: coverage varies significantly by area. Some councils are fully operational; others are still ramping up. If your local scheme isn't yet running, ECO4 may still be your fastest route before December 2026. You can read more about the broader programme in our guide to the Warm Homes Plan and what you can claim in 2026–27.
Does 0% VAT count as a grant for solar panels?
Not technically — but in practical terms it is the most accessible saving available to every UK homeowner right now, regardless of income. Under HMRC VAT Notice 708/6, the installation of solar panels, inverters, battery storage, and associated labour on a residential property is zero-rated for VAT until 31 March 2027. From 1 April 2027, the rate is legislated to revert to 5%.
The saving is automatic — your installer simply does not charge VAT on a qualifying supply-and-fit job. You do not need to apply for anything. But if an installer quotes you with VAT on a standard domestic solar installation, ask them to explain why.
Since 1 February 2024, standalone battery retrofits — adding storage to an existing solar system — also qualify for 0% VAT in their own right. That means if you already have panels and are considering adding a battery, doing so before April 2027 makes financial sense.
There is currently no confirmed extension beyond March 2027, so if solar is on your to-do list, the time to act is before that date. See our full breakdown in 0% VAT on Solar Panels: What to Do Before March 2027.
What about the Smart Export Guarantee — is that a grant?
The Smart Export Guarantee (SEG) is not a grant — it does not reduce your upfront costs. But it is a government-backed right that every solar homeowner should use, and it contributes meaningfully to your long-term savings.
Under SEG, Ofgem-licensed suppliers with 150,000 or more customers are legally required to offer you a tariff for any excess electricity your panels export to the grid. Rates are set competitively by suppliers — not fixed by government — so it pays to shop around. To qualify, your installation must be MCS-certified and you need a smart meter capable of recording half-hourly exports.

What's coming next? The 0% consumer loan scheme
For homeowners who don't qualify for any of the grants above, help is on the way — though not yet available. The government has committed to a 0% interest consumer loan scheme for solar panels, batteries, and heat pumps, backed by up to £2 billion of public funding. This is intended to be open to all homeowners regardless of income, not just lower-income households.
The scheme is not yet open for applications. It is expected to launch in phases from 2027, with full eligibility details and terms to be published during 2026. Until then, the 0% VAT window is the main saving available to homeowners who don't qualify for ECO4 or the Warm Homes Local Grant.

What grants have gone — and what should you ignore?
Several schemes have closed that older articles still mention. The original Feed-in Tariff closed to new applicants in March 2019 and is not available to new solar buyers. The Green Homes Grant was scrapped in 2021. There is no universal free solar grant open to all UK homeowners — any article claiming otherwise is either out of date or misleading.
ECO4 was originally due to end in March 2026 before being extended to December 2026 by the government in January 2026. The government has confirmed there will be no ECO5 — the Warm Homes Plan, which is government-funded rather than supplier-funded, is the intended replacement from 2027 onwards.
Is solar worth it even without a grant?
Honestly, it depends on your home. A south- or south-west-facing roof with little shade and a reasonably high electricity bill is likely to produce a meaningful return. A heavily shaded north-facing roof is a much weaker case. Our guide to solar panel payback time in 2026 sets out the honest numbers for different home types.
The 0% VAT saving, combined with SEG payments and reduced electricity bills, means the maths is more favourable right now than it will be after April 2027. But solar is still a significant purchase and it is only worth doing if the numbers stack up for your home — not based on what a salesperson tells you.

Frequently asked questions
Can I get a grant for solar panels if I own my home?
Yes, depending on your income and EPC rating. If your household income is under £36,000 and your home has an EPC rating of D–G, you may qualify for the Warm Homes: Local Grant (England) or ECO4 (closing December 2026). Every owner-occupier can benefit from 0% VAT on a qualifying solar installation until 31 March 2027, regardless of income.
Is ECO4 still open for solar panel applications in 2026?
Yes, but only until 31 December 2026, and funding is increasingly limited as the scheme nears its end. You must be on a qualifying means-tested benefit and have a home with an EPC rating of D–G. Note that under ECO4, solar PV is only funded for homes with electric heating or a heat pump — not gas-heated homes. Apply through your energy supplier as soon as possible, as processing can take 6–12 weeks.
What happens to solar grants after ECO4 ends in December 2026?
The Warm Homes: Local Grant (running to March 2028) is already live for eligible low-income households in England. A 0% interest consumer loan scheme open to all homeowners is expected to launch in phases from 2027, though full details have not yet been published. The government has confirmed there will be no ECO5.
Does the 0% VAT on solar panels apply automatically, or do I need to claim it?
It applies automatically on a qualifying supply-and-fit job. Your installer simply charges 0% VAT on the invoice — there is no form to fill in. The relief covers panels, inverter, battery, labour, and associated installation costs. It runs until 31 March 2027, after which the rate reverts to 5%, so completing your installation and having it invoiced before that date matters.
Do I need to use an MCS-certified installer to access grants and incentives?
Yes. MCS certification is required to access ECO4 funding, the Warm Homes: Local Grant, and the Smart Export Guarantee. The 0% VAT applies to any qualifying residential installation, but a reputable installer will be MCS-certified regardless. Always verify certification before signing anything — it is also your protection against cowboy operators.
