Finance options, if you need them
This is a 5 kWh all-in-one, not a 10 to 15 kWh wall kit. Typical UK 5 kWh installs still land around £3,000 to £4,500 once an electrician has been in. Larger 10 to 15 kWh systems are a different product class, typically £6,000 to £8,000. We do not pretend a 5 kWh box is the same size as those. If you need more later, expansion packs stack on the same system.

Typical 5 kWh installed range is from our home battery cost guide. 10 to 15 kWh systems are larger and cost more. Actual quotes vary by installer, brand and property.
Best-case range for a 5 kWh battery on Octopus Go (9.5p night, 33.555p to 37.4209p day, checked 10 October 2026), one full cycle a day with an assumed 90% round-trip efficiency, so real savings will be lower. That is up to about £35 to £41 a month. See how we worked it out or try the calculator.
