Average Cost of an Electric Car UK 2020

Electric cars are known for being cheaper to run than combustion engine cars, but how much does an electric car really cost? We've gathered data on three costs of EV ownership that people are often curious about: purchase prices, the cost of a full charge and the cost of electricity per mile.

Purchase Prices of Electric Cars UK

The average cost to buy an electric car in the UK is around £44,000, but prices range from £17,350 up to £138,826, or even more. Luxury cars such as Tesla, Porsche, Audi, Jaguar and Mercedes (many of which made our list of fastest electric cars) will set you back £80k on average, while a non-luxury EV costs £27k on average. The top 10 cheapest electric cars in the UK cost between £17,350 and £26,800.

Cost to Charge an Electric Car UK

The cost to fully charge an electric car ranges from £2.36 up to £15.49, assuming the unit cost of electricity is 16.3 pence per kWh. Charging costs largely depend on the size of the car battery (which determines the range of the car)—the usable size of batteries for EVs available in the UK ranges from the smallest batteries at just 14.5 kWh (Citroen C-Zero) up to the largest batteries with 95 kWh (Tesla Model S Long Range and Tesla Model X Long Range).

Luxury cars typically have larger batteries, so cost more to charge—but they deliver more range as a result. On the other hand non-luxury cars usually have smaller batteries so cost less to charge.

Non-luxury electric cars40.7£6.64
All UK electric cars57.7£9.41
Luxury electric cars81.1£13.21

We can also see how the cost to charge an electric car changes with battery size. For example, a car with an advertised battery size of 30 kWh will cost around £4.55 to fully charge; a 100 kWh battery would cost around £15 to charge.

30 kWh£4.55
50 kWh£7.58
80 kWh£12.13
100 kWh£15.16

An additional consideration is where you charge. Using a public charge point can be very expensive, especially for ultra-fast charging. For example, Ionity ultra-rapid EV charging costs 69 pence per kWh—more than 4X as much as home charging.

Electric Car Charging Cost Per Mile

Per mile, electric cars cost around 4.8 pence to power. Heavy, luxury cars cost more—around 5.3 pence per mile—while lighter-weight, non-luxury cars cost around 4.4 pence per mile.

Methodology

We gathered data from the EV Database on battery capacities, starting OTR prices (reflecting UK government grants up to £3,000) and ranges to learn more about the cost of EVs in the UK. Here are the cars we used in the study, which we grouped by luxury and non-luxury cars:

  • Hyundai Kona Electric 64 kWh

Note: to estimate the cost to fully charge cars by battery size, we adjusted the battery capacity because not all of a battery is usable. On average, the usable battery is 93% of the battery capacity of an electric car. To calculate the cost to fully charge a car, we therefore multiplied the advertised battery capacity of a car by 93% to find the usable capacity, then applied the unit cost of electricity.

Also, the 16.3p/kWh cost of electricity assumes cars are charged at home. Cars charged at expensive fast-charge public stations can cost multiples of these figures to charge.
