How do tariffs work?
Tariffs set out the way that energy companies charge you for your use of electricity. Electricity is measured in kilowatt hours (kWh) and your energy supplier will charge a unit rate for each kWh you use. Tariffs come with varying rates meaning you will pay a different price for energy depending on your tariff and that rate can change depending on the time of day. Charging your car at home means you use more energy and as a result your bill will go up. The increase is more than off-set by the savings you make on fuel but there are certain tariffs you can switch to that will reduce your bill even further.Why should I switch?
