How to Choose the Right Home Battery
Assess your daily usage
Check your smart meter or energy bill. The average UK home uses 8–10 kWh per day. Match your battery capacity to your evening/overnight consumption — typically 4–8 kWh.
Check your tariff
A time-of-use tariff (Economy 7, Octopus Go, Octopus Flux) is essential for maximum savings. The bigger the difference between peak and off-peak rates, the more you'll save.
Decide: plug-in or hardwired?
Plug-in batteries (plug-in) cost less, install in minutes, and suit most homes. Hardwired batteries (such as Fox ESS hybrid, EP Cube, Hinen or Duracell, fully installed via Battery Compare) give higher power output but cost more once installation is included.
Consider solar integration
If you have or plan solar panels, check compatibility. plug-in home batteries work with any solar setup. To automatically store excess generation you'll need the smart meter (CT clamp) — included with Pro Install, or available as a separate electrician-fitted add-on for self-install.
