By choosing to remain on a flat-rate tariff, you may be overpaying on your energy bills. You're missing out on the opportunity to maximise the cost savings available to you through smart charging your car.

Being on a flat-rate tariff means that you pay a fixed price for your energy 24h a day, seven days a week. Smart charging is designed to optimise your charging for the cheapest available times. If the price of your energy is always the same, you can't save by charging during cheaper, low demand windows.

By switching to an economy 7 or variable rate tariff you could save up to an additional £150 a year! The new E.ON Next Drive tariff which has an off-peak rate of only 4p/kWh is a great example of these new innovative tariffs designed for EV drivers. We realise that switching can be a hassle, so we've put together a handy list of suppliers and tariffs here.
