Calculators

Do the sums before you decide.

How much you save a year by charging at home, and how long your car takes to charge depending on the power you install. It is all worked out in your browser: we neither send nor store anything.

And every kilometre costs less.

Charging at home costs a fraction of what filling up costs. Choose how much you drive a year and see the difference.

The car has the final say: if its onboard charger takes less power than the charging point, it will charge at whatever it takes. We check this during the initial survey.
