About Battery Storage Cost

What is on this site

One question, "commercial battery storage cost", answered with a quote form that works on the page with no account, 3 guides on the questions around it, a data table you can cite (the figures and their method), and the sources every figure rests on.

• Battery storage without solar: is it worth it in the UK?: A battery without solar earns purely from tariff arbitrage: charge cheap off-peak, use at peak. When the maths works, when it doesn't, and the honest payback picture.
• 0% VAT on battery storage: the relief explained, 2024 to 2027: Battery storage installations carry 0% VAT since 1 February 2024, retrofit and standalone included, until 31 March 2027. How the relief works and who gets it.
• What size battery does a UK home need? 5kWh vs 10kWh: The average UK home uses about 2,700 kWh of electricity a year, roughly 7.4 kWh a day. Why 5kWh suits most homes, who actually needs 10kWh, and sizing mistakes.
