Switching to an electric vehicle (EV) is not just a greener, more sustainable choice—it can also save you money in the long run. But how much does it actually cost to charge your EV at home in the UK?

Average Cost of Home EV Charging

Using a standard 7kW home EV charger, such as Brim’s 7.4kWh charger, a full charge typically costs between £12 and £13. This is based on the average UK electricity rate—but your actual cost may vary depending on a few key factors.

Let's break it down:

What Affects the Cost of Charging Your EV?

Electricity Tariffs

• Standard rate: Charging during the day at peak hours can cost more. 

• Smart EV tariffs: Many UK energy providers offer off-peak EV charging tariffs, with rates as low as 7p per kWh—especially during overnight hours.

Tip: Consider switching to an EV-specific electricity plan to lower your charging costs. Companies such as Octopus Energy, EDF and British Gas offer EV Super off peak tariffs. 

Battery Size

• Larger EV batteries store more energy and take longer to charge.

• For example, a 60kWh battery will cost more to charge than a 40kWh one, even at the same rate per kWh.\

State of Charge (SoC)

• Charging from 0% to 100% uses more energy and time than topping up from 30% or 50%.

• Frequent partial charges are more efficient and can extend battery life.

Weather Conditions

• Extreme cold or hot weather can affect charging efficiency.

• Cold temperatures, in particular, may slow down charging and increase energy use.

Making the most of an EV charging tariff can offer super off-peak tariffs as cheap as 7p per kWh!
