UK Solar Grants & Incentives 2026
There's a lot of "free solar panels" clickbait about. Here's the honest position for 2026: everyone gets 0% VAT and can earn from exporting power, but genuinely free or fully-funded solar is limited to low-income and fuel-poor households through specific schemes. Three of these schemes have hard end dates. Here is every route, who qualifies, when the deadlines are, and how to claim.
⏰ Three deadlines you need to know
31 Dec 2026 - ECO4 closes. The last scheme that can fully fund solar for low-income households ends this year. Read our ECO4 deadline guide for what to do and who qualifies. 31 Mar 2027 - 0% VAT expires. When the zero-rate ends, a typical install costs ~£1,200-£1,600 more overnight. Contract before the deadline to lock in the saving. Warm Homes Fund (TBC) - 0% loans for everyone. The government's promised interest-free loan scheme for all homeowners still has no launch date. If and when it lands, it could be the biggest solar incentive yet. We are tracking this.

The Warm Homes Fund promises 0% loans for solar and energy-efficiency upgrades, open to all homeowners regardless of income. The catch: it was first trailed in 2025 and still has no confirmed launch date as of August 2026. Government says \"later in 2026.\" When (if) it lands, this will be the most accessible solar incentive in the UK. We are watching this space.
The Warm Homes Plan, published on 20 January 2026, is the biggest home-upgrade programme in British history. It consolidates and expands existing schemes, so grant availability is expected to widen over 2026-27. Check GOV.UK and your local council for the latest eligibility as new funding rounds open.

DIY installers: staying eligible
The catch for DIYers is that SEG and grant funding require MCS certification, and a pure self-install isn't MCS-certified. The standard workaround: do the physical work yourself, then pay an MCS-registered electrician to design, inspect, certify and sign off the system. You keep most of the labour saving and stay eligible for export payments. See our installation guide for how this fits into the build.

Frequently asked questions
Can I still get free solar panels in the UK in 2026?
Only through targeted schemes for low-income or fuel-poor households. ECO4 (to 31 Dec 2026) can fund solar for eligible benefit claimants in electrically heated homes, and the Warm Homes: Local Grant covers households with income of £36,000 or less and an EPC of D-G. There's no universal free-solar scheme.
Do I pay VAT on solar panels in 2026?
No -- domestic solar and battery installations are zero-rated (0% VAT) in Great Britain until 31 March 2027. On a typical £6,000-£8,000 system that saves roughly £1,200-£1,600. It applies to supply-and-install work by a VAT-registered installer.
Can I claim 0% VAT if I install solar myself?
The relief is built around a supply-and-install contract, so buying panels alone at retail doesn't automatically get 0% VAT. If a VAT-registered contractor installs materials for you, the zero rate can apply to that installation work. Pure DIY buyers usually pay standard-rated retail prices on the hardware.
How much can I earn from the Smart Export Guarantee?
SEG rates in 2026 range from about 2p to 29p per kWh depending on supplier. A typical 4kW system exporting around half its generation might earn £150-£400 a year. You need an MCS-certified install and a smart meter.
Do I need MCS certification for grants and SEG?
Yes -- SEG and grant-funded installs require MCS-certified equipment and installation. A pure DIY install isn't MCS-certified, but you can pay an MCS-registered electrician to design, sign off and certify the system so you stay eligible.
