As electric cars (EVs) become increasingly popular in the UK, many drivers are curious about the costs involved, especially when it comes to charging. The price to charge an electric car can vary depending on several factors, including the size of your car's battery, the type of charger you use, and the electricity tariff you have. In this guide, we’ll break down the key elements that determine how much it will cost to charge your electric vehicle and highlight energy providers offering special EV deals, making it easier for you to save on your charging costs.
Factors That Affect the Cost of Charging an Electric Car
The cost to charge your EV depends on a few key factors. Let’s take a look at what you need to consider when calculating your charging costs:
1. The Size of Your Car’s Battery
The bigger your car’s battery, the more it will cost to charge. Electric vehicle batteries are measured in kilowatt-hours (kWh), and most cars have batteries ranging from 30 kWh to 100 kWh. The larger the battery, the more energy is required to fully charge it.
Example: A vehicle with a 60 kWh battery will require more energy to charge than a car with a 30 kWh battery, making it more expensive to charge.
2. Charging Location
Home Charging: If you have access to a home charging point, this is typically the most cost-effective option. The cost of home charging depends on your electricity tariff. You can either use a standard 3-pin plug (which is slower) or install a dedicated EV charging point for faster charging.
Public Charging: Charging your EV at a public charging station can be more expensive than home charging, with prices varying depending on the station and network. You can expect to pay more for fast and rapid chargers compared to slower chargers.
3. Electricity Tariff
The price you pay for electricity depends on your energy provider and the tariff you’re on. Many energy providers now offer special EV tariffs designed specifically to help you save money when charging your electric car. These tariffs typically offer lower rates for charging at night, during off-peak hours when demand is lower.
Tip: Switching to an EV-specific tariff can help you reduce your charging costs significantly, especially if you charge your car overnight.
4. Charging Speed
Fast Chargers and Rapid Chargers: These chargers can fill up your battery more quickly, but they usually come with a higher price tag compared to slower chargers. For example, rapid chargers can cost between £0.30 and £0.50 per kWh, while standard chargers may be cheaper, around £0.20 per kWh.
How Much Does It Cost to Charge an Electric Car at Home?
Charging your EV at home is usually the most affordable option, but how much it will cost depends on your car’s battery size and your electricity tariff. On average, it costs between £6 and £15 to fully charge an electric car at home.
Example Calculation:
If you own an electric car with a 40 kWh battery, and your electricity provider charges 15p per kWh, a full charge would cost approximately £6.
A larger battery, such as the 75 kWh battery in a Tesla Model 3, would cost about £11 to £15 to fully charge at home, depending on your tariff.
Energy Providers Offering Special EV Tariffs
Several energy providers in the UK now offer EV-specific tariffs that can make charging your electric car cheaper, especially if you charge during off-peak hours. These tariffs typically provide lower rates for charging your car at night, allowing you to take advantage of cheaper electricity costs. Here are some of the top energy providers offering deals for EV drivers:
What they offer: Octopus Energy provides an excellent tariff for EV owners called the Octopus Go. This tariff offers cheap off-peak electricity during the night (typically between 00:30 and 04:30), which is ideal for overnight EV charging. The rate is much lower than standard tariffs.
2. EDF Energy
What they offer: EDF offers an Electric Vehicle Tariff that provides a lower rate for EV charging between midnight and 4 AM. It’s designed to help EV owners save on charging costs by taking advantage of off-peak electricity rates.
3. Bulb
What they offer: Bulb offers a cheaper energy tariff for electric car owners, which allows customers to save on their overall energy costs by using off-peak electricity to charge their vehicles.
4. SSE
What they offer: SSE provides a Go Electric Tariff, which includes a cheap night-time rate for charging your electric car. You can take advantage of SSE’s flexible tariffs that let you choose the best time to charge.
5. E.ON
What they offer: E.ON offers a Drive Tariff specifically for EV owners. This tariff provides lower rates during off-peak times for EV charging, making it an excellent option for those looking to charge their car at night at a discounted rate.
How Much Does It Cost to Charge an Electric Car at Public Charging Stations?
Charging your EV at public charging stations is often more expensive than home charging. On average, public charging costs range from £0.20 to £0.50 per kWh, depending on the charger type and location.
Slow Chargers: Typically cost around £0.20 per kWh.
Fast Chargers: Usually cost between £0.30 and £0.40 per kWh.
Rapid Chargers: These are the fastest option but tend to be the most expensive, ranging from £0.40 to £0.50 per kWh.
You can use apps and websites like Zap-Map or ChargePoint to find nearby charging stations and compare prices.
How to Save Money on Charging Your Electric Car
Here are a few tips to help you reduce the cost of charging your electric car:
Switch to an EV Tariff: As mentioned earlier, many energy suppliers offer discounted tariffs for electric car owners, making home charging much more affordable.
Use Off-Peak Charging: If your energy supplier offers off-peak tariffs, make sure to charge your car overnight to save money.
Use Public Charging Stations Wisely: Look for free or low-cost charging stations, and consider using slower chargers if you’re not in a rush.
Install Solar Panels: If you own your home, installing solar panels can allow you to charge your electric vehicle using clean, renewable energy, reducing your reliance on the grid.
Final Thoughts
Charging your electric car can be affordable, especially if you choose the right energy tariff. By switching to an EV-specific plan, charging overnight, and using public charging stations strategically, you can reduce your overall charging costs. Plus, with a variety of energy providers offering tailored deals for EV drivers, you have many options to help you save on electricity bills.
By understanding the factors that influence charging costs and making informed choices, you can keep your electric vehicle running without breaking the bank.
