How Much Does It Cost to Charge an Electric Vehicle (EV)?

With the UK set to ban the sale of new petrol and diesel cars by 2030, electric vehicles (EVs) are becoming an increasingly popular choice for drivers. As more people look to reduce their carbon footprint and avoid rising fuel costs, the shift towards EVs is well underway. Offering lower running costs and environmental benefits, EVs present a sustainable alternative to traditional combustion-engine vehicles. But one of the key questions for many prospective owners is: how much does it cost to charge an electric vehicle compared to filling up with petrol or diesel? Let’s break it down.

What Factors Affect the Cost of Charging an Electric Car?

Several factors influence the cost of charging your electric vehicle (EV). Here’s a quick breakdown of the key considerations:

1. Charging Location

  • Home Charging: Charging your EV at home is usually the most cost-effective option, especially if you’re on a cheaper, off-peak electricity tariff.
  • Public Charging: Public chargepoints vary in cost. Some, like supermarket chargepoints, can be free, while others, particularly rapid chargers at service stations, tend to be more expensive.

2. Vehicle Type and Battery Size

  • Larger EVs with bigger batteries will require more electricity to charge, which could lead to higher costs.
  • The efficiency of your vehicle also plays a role in how much energy it uses per mile.

3. Electricity Rates

  • Home Tariffs: The cost per kWh of electricity varies depending on your home energy provider and tariff.
  • Public Chargepoints: Prices can range significantly depending on the provider and whether you’re using a fast or rapid charger.

Understanding these factors will help you estimate your EV charging costs more accurately.

How Much Does It Cost to Charge an EV?

The cost of charging an electric vehicle (EV) can vary depending on whether you charge at home or at public chargepoints. Here’s a breakdown of the potential costs in both scenarios:

Charging Location Cost for 10,000 miles/year Cost Per Mile
Home Charging £523.18 5.2p
Public Chargepoints £1,297.78 13p
70% at Home, 30% Public Chargepoints £755.55 7.6p

Charging at Home

Charging your EV at home is often the most convenient and affordable option. You can take advantage of off-peak electricity tariffs, which can significantly reduce your costs. A dedicated home chargepoint also ensures faster and safer charging than a standard UK socket.

  • Annual cost for 10,000 miles: £523.18
  • Cost per mile: 5.2p

Charging at Public Chargepoints

Public chargepoints can be found at locations such as supermarkets, service stations, and car parks. The cost of using these chargers varies depending on their speed (standard, fast, or rapid). Rapid chargers, which provide the quickest charge, are generally the most expensive.

  • Annual cost for 10,000 miles: £1,297.78
  • Cost per mile: 13p

Combined Charging (70% at Home, 30% at Public Chargepoints)

If you regularly charge at both home and public chargepoints, the blended cost will be somewhere between the two. This method offers flexibility but can still result in notable savings compared to traditional petrol or diesel vehicles.

  • Annual cost for 10,000 miles: £755.55
  • Cost per mile: 7.6p

Charging at home remains the most economical option, but public chargepoints offer convenience for longer journeys or those without home chargepoint access.

How Much Does Charging an EV Add to Your Electricity Bill?

Charging an electric vehicle (EV) at home will naturally increase your electricity bill, but it is still considerably cheaper than paying for petrol or diesel. The exact increase depends on several factors, such as your electricity tariff, how often you charge, and your overall energy consumption.

Impact on Home Energy Bills

On average, charging an EV at home for 10,000 miles annually could add around £523.18 to your electricity bill. This estimate assumes an average electricity price of around £0.14 per kWh on a standard home tariff. While this may seem like a significant rise, it is far less than the cost of fuel for a petrol or diesel vehicle.

  • Annual EV charging cost (home): £523.18
  • Annual petrol/diesel cost (for comparison): £1,554.64 (for a petrol vehicle driving 10,000 miles)

Smart Tariffs and Off-Peak Charging

Many energy suppliers offer specific EV tariffs that make charging even more affordable, especially if you take advantage of off-peak electricity rates. These tariffs allow you to charge your EV during low-demand hours, typically overnight, at a reduced rate. Switching to a dedicated EV tariff could reduce your charging costs even further.

  • Example savings with off-peak tariffs: Up to £300 annually compared to standard tariffs.

Potential Savings vs. Fuel Costs

The switch to electric vehicles doesn't just cut fuel costs; it can also help you save money in the long term, even with the added electricity usage. As electricity is typically cheaper than petrol or diesel, the overall cost per mile is significantly lower.

  • Cost per mile (home EV charging): 5.2p
  • Cost per mile (petrol vehicle): 14p

By charging at home and using smart tariffs or off-peak hours, EV owners can drastically reduce their transportation costs compared to traditional vehicles.


What is the Best Way to Charge an Electric Car?

The most cost-effective and convenient way to charge your EV is typically at home, especially if you have access to a driveway or garage. Charging overnight with a dedicated chargepoint can save you significantly, with costs around £523.18 per year for 10,000 miles. Many energy providers also offer off-peak tariffs, allowing you to charge during low-demand hours for even lower rates.

Public charging is useful for longer trips or when you're away from home but tends to be more expensive, costing up to £1,297.78 annually for the same mileage. Rapid chargers, while convenient, are the priciest option.

Tip: To maximise savings, consider switching to an EV-friendly energy tariff and use government grants to install a home chargepoint.
