The short answer
There is no universal cash grant for owner-occupiers to buy solar, but three forms of support exist: 0% VAT until 31 March 2027, ongoing income from the Smart Export Guarantee (SEG) for exported power, and means-tested help for qualifying low-income households through schemes such as ECO and the Warm Homes route. Headlines promising 'free solar panels' usually refer to those means-tested schemes or to finance deals — always read the eligibility and the small print.
The support picture is often misrepresented online. Here's what's real, what's conditional, and what to be sceptical of.

What's genuinely available
- 0% VAT on residential solar and batteries until 31 March 2027 (expected 5% after).
- Smart Export Guarantee: ongoing payments for surplus power you export.
- ECO / Warm Homes: help for qualifying low-income or vulnerable households, delivered via approved installers — eligibility-tested, not universal.
How to check what you qualify for
For means-tested schemes, eligibility usually depends on income, benefits or your property's energy rating, and is confirmed by an approved installer or your local authority — not by an advert. For everyone else, the practical 'support' is the 0% VAT window plus SEG export income. Use official sources (gov.uk, Ofgem, Energy Saving Trust) to verify any scheme before sharing personal details.
Frequently asked questions
Is there a government grant for solar panels?
There's no universal cash grant for owner-occupiers. Support comes via 0% VAT until March 2027, SEG export income, and means-tested schemes such as ECO and Warm Homes for qualifying households.
Are 'free solar panels' real?
Offers of free panels usually mean a means-tested grant you must qualify for, or a finance deal you repay over time. Always read the eligibility and small print before engaging.
Will I still get 0% VAT?
Residential solar and batteries carry 0% VAT until 31 March 2027, after which it is expected to return to 5%. Your installer should reflect the current treatment in the quote.
