# Battery Storage Cost

> Commercial battery storage cost in the UK: no published price scale exists, so this sets out what drives a quote, the payback arithmetic, and domestic pricing.

## Key facts

- A 5kWh home battery typically costs £2,500–£4,500 installed in 2026 quotes; a 10kWh system runs £4,500–£7,000 (varies by brand and installation complexity).
- Battery storage installations have carried 0% VAT since 1 February 2024, including retrofit and standalone batteries, with the zero rate scheduled until 31 March 2027 (HMRC VAT Notice 708/6).
- Typical home battery payback is 8–12 years and depends on the gap between your peak and off-peak rates, batteries earn by moving your usage, not by existing.

## Data

- What sets a commercial battery storage cost, and domestic prices for reference. Methodology: We publish no price range for commercial battery storage because we have not measured one, and no supplier publishes a scale: commercial systems are priced against a specific load profile, connection position and cycling regime. The domestic ranges are typical installed quotes for lithium home batteries observed across the UK market in 2026, varying by brand, usable capacity and configuration. The VAT position is per HMRC VAT Notice 708/6: the zero rate has covered battery storage installations, including standalone and retrofit, since 1 February 2024.
