A home battery doesn't need solar to pay its way. On a time-of-use tariff it charges overnight on a cheap rate, then powers your home through the expensive daytime and evening — so you buy far less electricity at the full price. Set the sliders to your home for an instant guide.
Estimate only — savings depend on your tariff and usage pattern. A free survey gives the exact figures for your home.
Got a roof that catches the sun? Adding panels stacks solar generation on top of these savings — try the solar & battery calculator.
Time-of-use tariffs such as Octopus Go or Intelligent give you a few hours of very cheap electricity overnight. Your battery fills up while rates are low, ready to run the home when prices climb. Defaults use a 7p/kWh off-peak rate — adjust it under "Advanced".
Through the day and the evening peak the home draws from the battery instead of the grid, so you sidestep the full day rate. The saving is the gap between the day rate and the off-peak rate, on every unit the battery delivers.
We model a typical household demand curve and only count energy the battery can actually deliver. A 10% round-trip loss is included, and once a battery covers your daily use, going bigger adds little — so the estimate won't over-promise.
This estimate is for a battery on its own — no panels needed. If you do have a sunny roof, solar charges the battery for free on top of this, and our solar & battery calculator shows the combined picture.
