There is no battery purchase grant in the UK
No government scheme pays for your battery. What genuinely helps: 0% VAT on residential battery installations until 31 March 2027 (then 5%), typically worth £1,000-3,000 versus the standard 20% rate, and the tariff maths. Exported solar earns around 12p/kWh on a typical SEG flat rate while grid power costs around 25p/kWh (Ofgem cap average, changes quarterly), so a stored kWh you use at home is worth roughly double one exported. Households on EV or time-of-use tariffs can also charge the battery cheaply overnight and run the house off it at peak times.
