Grants & tax
Grants, VAT relief and what actually qualifies.
There is no direct UK government grant for home batteries in 2026 — but 0% VAT runs until 31 March 2027, after which the rate reverts to the 5% reduced rate (VAT Notice 708/6). Installing before the deadline saves around £225–£425 on a typical install.
