Owning an electric car comes with many cost-saving advantages, from cheaper road tax and government grants, to cheaper running costs.

One of the most common questions new EV owners ask is ‘how much does it cost to charge an electric car?’

The cost to charge an electric car can vary depending on how you choose to charge your vehicle, as well as your vehicle model. Although, what is for certain is that EV charging costs are considerably lower than fuelling a petrol car.

EV charging costs can also differ between home, work, and public charging stations. So depending on your lifestyle and the way you intend to charge your electric vehicle, the costs of charging in the UK can differ.

There is a simple way to work out the cost of charging an electric car. Running costs can be calculated by pence per kilowatt hour (kWh). By working out the pence per kWh, you can calculate the average cost to charge your electric car and charge more efficiently. 

Here’s a run down of EV charging costs in the UK, based on battery size, home charging and public charging. 

Calculate Your EV Charging Costs

When calculating your EV charging costs, it’s useful to know or have an estimate of your energy tariff. Energy suppliers will usually charge by kWh as a standard measurement of energy usage.

To calculate the cost of fully charging your electric car, multiply your energy supplier’s kWh charge by your car’s battery size. For instance, if your energy tariff charges 16p per kWh, and your car’s battery size was 40kWh, the cost to fully charge your car would be £6.40:

Pence per kWh cost (16p) x battery size (40kWh) = full charge cost (£6.40)

Using this simple formula, you can calculate the cost of charging an electric vehicle at home.

Cost Of Charging An Electric Car At Home

Charging your electric car at home is one of the most popular ways to power up your EV. Charging at home provides ultimate convenience, with a dedicated charging station that powers up the car battery as and when it is needed. 

But, how much does it cost to charge an electric car at home?

UK home electricity prices are on average around 17p per kWh. Using this as an average figure, the table below shows examples of how much it costs to charge an electric car at home.

ModelBattery SizeDrive RangeAverage Cost of Full ChargeAverage Cost Per Mile
Volkswagen ID.358kWh264 miles£9.863.7p
Nissan LEAF40kWh168 Miles£6.804p
Tesla Model 375kWh360 Miles£12.573.5p

The cost of charging an electric car at home is considerably lower than many people often expect before becoming an EV owner. In comparison to the cost per mile in a petrol vehicle, charging an electric car is the more cost-effective option. 

Additionally, many energy suppliers offer a dual-rate tariff specifically for electric car charging. These tariffs offer a cheaper energy rate during off-peak hours, such as overnight. Octopus Energy’s Go tariff offers energy as low a 5p per kWh over a four-hour nighttime period. Additionally, they offer a £50 reward when you refer a friend.

This would make charging the Volkswagen ID.3 cost as little as 1p per mile to drive.

Saving Costs With A Smart Home Charger 

One of the major cost-saving benefits of charging from home is that you can choose a specialised home charger that best suits your budget and lifestyle.

For instance, a smart home EV charger can significantly reduce the cost of charging your electric vehicle. Smart home chargers offer advanced features, such as scheduled charging times that only use power during off-peak hours, when electricity supply is cheaper.

Many leading EV charger manufacturers offer scheduled charging through a free mobile app, meaning you can even schedule and monitor your electric car charging costs on the go.

Some smart home chargers take cost-saving measures to a new level.

The Zappi 207UB comes with eco modes that charge your electric car using any surplus energy from your home, helping save costs on your total energy bill.

Cost of Public Electric Car Charging Stations

Public car charging stations are something that we see more and more commonly, often in the car parks of supermarkets, gyms, petrol stations or even office buildings. 

As more UK drivers make the switch to electric, commercial spaces are introducing public car charging stations available for EV owners. 

Charging your car in public is a great way to top up your electric vehicle on the go, and many places offer public charging for free. Although, some public chargepoints charge a standard tariff usually paid via an app or card. 

Whilst the costs of charging an electric car at a public charging station are low, it can be impractical as a long-term charging solution. Additionally, public chargers often offer slower charging speeds than the impressive speeds offered by home charge points, making home charging the more cost-effective option.

EV Charging Costs: Things to Consider

Whilst the cost of EV charging is much cheaper than the cost of fuelling petrol vehicles, there are ways to make sure your EV charging costs are kept within your budget. 

If you are looking to buy an electric vehicle, or just looking to understand the costs of charging your electric car, there are important factors to consider. These can include:

  • Your electric car’s battery capacity (kWh)
  • Your energy tariff’s cost per kWh
  • Your EV charger’s smart features

Your electric car’s battery capacity (kWh) will tell you how much energy your EV can consume and hold. Knowing this will help you work out how much energy is required to fully charge your electric car battery, and with the cost of your energy tariff’s kWh charge, how much it will cost to charge your electric vehicle.

Additionally, it’ll be useful to consider how your home charger’s smart features can help save on costs in order to fully understand your budget. To understand more about the cost-saving features that home chargers can offer, explore our range:
