How it saves you money
Buy electricity when it's cheap, use it when it's expensive
Charge overnight
On a smart tariff such as Octopus Agile or Intelligent Go, off-peak electricity can cost a fraction of the daytime rate. The battery fills up while you sleep.
Already have solar? Keep the surplus
Every system we fit uses a hybrid inverter, so if you already own panels their surplus charges the battery instead of being exported for pennies.
Run the house at peak
Evenings run on stored power, so you barely touch the expensive peak rate. Many customers see bills fall by well over half.

Questions
Is battery storage worth it?
For most homes on a smart tariff, yes — and unlike solar it works whatever your roof faces, with no scaffolding and a one-day install.
What size battery do I need?
It depends on how much electricity you use in the evening. A typical home starts at 5–10kWh; we size it from your bills so you don't overpay.
Will it keep the power on in a cut?
Systems with an EPS or backup gateway can run essential circuits during an outage. Tell us if this matters and we'll spec for it.
Where does it go?
Usually a garage, utility room, loft or external wall. Most installs are completed in a day.
