How much does it cost to charge an EV?

The cost of charging an electric vehicle varies based on several factors such as the vehicle model, battery capacity, charging speed and electricity rates. Prices also differ depending on whether you’re charging at home, at work or using public charge points whilst on-road.

Calculating the cost to charge an EV

To calculate the cost of charging your EV, you should consider the cost in pence per kilowatt-hour (kWh), rather than pence per litre. A kWh is a standard unit of measurement of energy that your supplier uses to bill you. To estimate the cost of a full charge, you can multiply the battery size of your EV by the electricity price per kWh from your supplier.

As of April 2024 (Ofgem), the average standard electricity rate in the UK is roughly 24.5p per kWh. For a typical electric car with a 70kWh battery, it would cost approximately £17.15 for a full charge. Considering the average range of an EV is 240 miles, the cost of charging remains lower than traditional fuel costs.

The table below shows the charging costs for three example vehicles, based on the average standard electricity rate in the UK. From this information, we can determine the pence-per-mile cost.

Cost to charge an EV at home

Charging your EV at home is often the most convenient and cost-effective way to charge your EV. Home chargers typically have a power output of 7kW, charging the average EV in approximately 8-10 hours. Due to this, many drivers prefer to charge their EV overnight, allowing them to start the day with a full battery. When combining overnight charging with an off-peak energy tariff, home charging becomes even cheaper. Off-peak energy tariffs mean your EV is charged, often periodically, throughout the night when the electricity prices are cheapest. As of March 2024, the average off-peak energy rate is 7.5p/kWh, costing just £5.25 to fully charge an EV with a 70kWh battery.

Public EV charging cost

Public EV chargers are generally more powerful and robust than home chargers, allowing drivers to quickly recharge whilst on the road. As more power is being delivered to your vehicle at a quicker rate, on-road charging tends to be more expensive than charging at home. The table below shows approximate pricing for charging on-road, based on the speed of the charger.

Rapid charging is unlikely to be part of your everyday charging routine, but access to these charge points is essential for long car journeys.

EV charging point cost

The price of a charge point depends on the hardware model and the power output chosen. As the power output increases, the hardware size and price usually increase in line with this. Contact our EV team for more information on pricing.
