GivEnergy All in One
B4.2 13.5kWh
Integrated battery, inverter and gateway in one cabinet, with whole-home backup. A strong fit for storage on a single unit, but check warranty support given GivEnergy's recent administration.

Our verdict
The All in One simplifies installs by combining storage, hybrid inverter and a backup gateway, with strong value per usable kWh. GivEnergy entered administration in 2026, so the brand may continue, but confirm who stands behind the 12-year warranty before buying.
Good
- Whole-home backup included
- High usable capacity
- Single-cabinet install
Watch out
- Warranty support uncertain after administration
- Large physical footprint
Will it pay for itself?
14.6 years to pay back a £4,999 GivEnergy All in One from £342 a year of off-peak savings. That's 2.6 years after the warranty ends.
A typical home using 9.3 kWh a day, 58% of it at
peak. Day rate 26.32p, Intelligent Octopus Go off-peak 8p, 89% round trip. Hardware only, so installation adds to the payback time. Rates
