Solar Panel Grants UK 2026: Every Scheme Explained

Solar panel grants available in the UK in 2026 include free solar through the Warm Homes Local Grant (for low-income households in England), ECO4 (for homes with electric heating), 0% VAT on residential installations until March 2027, and Smart Export Guarantee payments for surplus electricity exported to the grid.

"Can I get free solar panels?" is one of the most searched energy questions in the UK. The answer is more nuanced than most websites admit. This guide covers every scheme available in 2026 — who actually qualifies, what's covered, and how to apply.

Every solar scheme at a glance

1. Warm Homes: Local Grant — the main route to free solar

The Warm Homes: Local Grant is the UK government's flagship energy efficiency programme, backed by £500 million in funding. It provides completely free home energy upgrades — including solar panels — to eligible homeowners.

Who qualifies

• Homeowners or private tenants in England (with landlord consent for tenants)
• Household income below your council's threshold (typically £31,000–£36,000)
• EPC rating of D, E, F, or G (meaning your home is energy-inefficient)
• Not in social housing (different schemes apply)

What's covered

Solar panels are one of several measures that can be installed — but only if a home assessment recommends them. Other measures include wall insulation, loft insulation, underfloor insulation, air source heat pumps, and smart heating controls. The assessor decides what's most cost-effective for your home.

Important: You can't request solar panels specifically. The scheme aims to improve your home's overall energy efficiency, and the assessor may recommend insulation before solar if your home isn't well insulated. This is actually in your interest — solar saves more money when your home doesn't leak heat.

How to apply

1. Check your eligibility using our free eligibility checker
2. Contact your local council's energy efficiency team
3. A surveyor visits your home to assess what improvements are needed
4. Approved improvements are installed at no cost to you

2. ECO4 — funded by your energy supplier

The Energy Company Obligation (ECO4) requires large energy suppliers to fund home energy improvements for vulnerable and low-income households. It has been extended to 31 December 2026.

Who qualifies

• Receiving qualifying benefits: Universal Credit, Pension Credit, Child Tax Credit, Income Support, Housing Benefit, or Income-based JSA/ESA
• Home with EPC rating D, E, F, or G
• Or via your council's ECO Flex pathway (broader criteria including low income without benefits)

Key difference from the Warm Homes Grant

ECO4 is funded by energy suppliers, not the government. This means your energy supplier (or an ECO-accredited installer working on their behalf) arranges and pays for the work. The measures are similar — insulation, heating, and potentially solar panels — but the eligibility route is different.

Act soon: ECO4 ends on 31 December 2026, and there will be no successor scheme. Once suppliers meet their obligations, they stop funding installations. Don't wait until December.

3. 0% VAT — for everyone

This is the scheme that benefits every UK homeowner, regardless of income. Since April 2022, residential solar panel installations are charged 0% VAT instead of the standard 20%.

On a typical solar system costing £7,000 before VAT, this saves you £1,400. It applies to:

• Solar panels (PV systems)
• Battery storage
• Solar thermal panels (hot water)
• Insulation materials
• Heat pumps

The 0% rate is confirmed until at least March 2027 (HMRC guidance). It applies automatically — your installer handles the VAT.

4. Smart Export Guarantee — get paid for surplus

The Smart Export Guarantee (SEG) isn't a grant — it's a payment scheme. Once your solar panels are installed, energy suppliers must offer you a tariff to buy your surplus electricity.

To qualify, you need:

• An MCS-certified installation (non-negotiable)
• A smart meter or SMETS2 meter
• A system of 5MW or less (all residential systems qualify)

Best SEG rates in 2026

• Octopus Outgoing Fixed: 15p/kWh — the best fixed rate
• Octopus Agile Outgoing: Variable (tracks wholesale prices, can exceed 30p/kWh at peaks)
• Most other suppliers: 4–6p/kWh

Choosing the right export tariff can double or triple your export income. Our solar calculator uses live Octopus Energy rates for your region.

Don't qualify for a grant? Solar is still worth it.

Most UK homeowners won't qualify for free solar panels — the income thresholds are deliberately targeted at those who need help most. But that doesn't mean solar is out of reach.

With 0% VAT, falling panel costs, and electricity at around 24.50p/kWh (Ofgem price cap, Q2 2026), a typical solar system pays for itself in 8–12 years and then provides 15+ years of near-free electricity. Many installers also offer 0% finance options, spreading the cost over 10–15 years with no interest.

Watch out for "free solar panel" scams

A warning: if someone cold-calls or knocks on your door offering "free solar panels from the government," be cautious. Legitimate schemes work through councils and energy suppliers, not door-to-door salespeople.

Red flags:

• Pressure to sign immediately — real grants don't expire in 24 hours
• Upfront fees — legitimate schemes are free; you should never pay to "apply"
• No MCS certification — always verify the installer on the MCS register
• Vague about which scheme — ask specifically: "Is this under the Warm Homes Local Grant or ECO4?"
• Not TrustMark registered — check on trustmark.org.uk

What's coming next: the Warm Homes Plan

The government's broader Warm Homes Plan includes nearly £15 billion in funding for home energy efficiency over the coming years. This includes:

• An additional £1.5 billion in capital funding from 2027/28 onwards
• Proposed low-interest and zero-interest loans for solar and insulation
• Under the proposed Future Homes Standard, all new-build homes are expected to have solar panels from April 2027

The direction is clear: the UK is moving towards solar being standard on every home. Getting panels now means you benefit from current schemes and start saving immediately, rather than waiting for future programmes that may have different terms.
