How much to charge an electric car? Around 26.11p per kWh

Charging an electric car in the UK typically costs around 26.11p per kilowatt-hour (kWh) for those on a standard variable home tariff, though this figure can fluctuate significantly based on where and when you charge. Understanding these costs is crucial for UK electric vehicle (EV) owners and prospective buyers looking to manage their running expenses effectively. This guide breaks down the various factors influencing EV charging costs, from home charging to public networks, and offers strategies to keep your bills down.

Understanding electric car charging costs in the UK

Electric vehicle ownership brings a new set of considerations, particularly around "fuelling" costs. Unlike petrol or diesel cars, where prices are relatively straightforward at the pump, EV charging costs can vary widely depending on your charging habits and the electricity tariff you use.

The basics of EV charging costs

The fundamental unit for measuring electricity is the kilowatt-hour (kWh). Just as you pay per litre for petrol, you pay per kWh for electricity. The price you pay for each kWh is your unit rate, and this forms the basis of your charging expenses. Beyond the unit rate, a daily standing charge also applies to your electricity bill, covering the fixed costs of supplying energy to your home.

Key factors influencing your bill

Several factors determine how much you pay to charge your EV. These include the size of your car's battery (measured in kWh), the efficiency of your vehicle, the type of electricity tariff you are on, and whether you charge at home or use public charging infrastructure. The time of day you charge can also significantly alter the cost, especially with tariffs that offer different rates for peak and off-peak periods.

Home charging costs: optimising your savings

Charging your EV at home is typically the most cost-effective option, offering greater control over your expenses.

Standard home tariffs

For those on a standard variable home tariff in the UK, the electricity unit rate is around 26.11p per kWh, effective from 1 July to 30 September 2026. This rate is set by the energy price cap regulated by Ofgem, the UK's energy regulator. The average UK home uses around 2,500 kWh of electricity per year, so understanding your unit rate is the first step to calculating your EV charging costs.

Dual-rate variable tariffs and off-peak charging

Significant savings can be achieved by switching to a dual-rate variable tariff, which offers different pricing depending on the time of day. These tariffs provide much lower rates during off-peak hours, typically overnight. To be eligible for a dual-rate tariff, you generally need a smart meter or a multi-register meter installed at your property, allowing your energy supplier to accurately track your consumption during different time periods.

Public charging costs: navigating networks and speeds

While home charging offers the best value, public charging is essential for longer journeys or when home charging isn't feasible. However, public charging often comes at a higher price.

Rapid, fast, and slow chargers

Public charging points vary by speed:

• Slow chargers (typically 3-7kW) are often found at destinations like workplaces or supermarkets and can take several hours to fully charge an EV.
• Fast chargers (7kW to 22kW) are more common and offer a quicker charge, suitable for a few hours of parking.
• Rapid chargers (50kW and above) are the fastest option, often found at motorway service stations, capable of adding significant range in a short period.

The faster the charger, the more expensive the per-kWh rate usually is.

Public charging network pricing

Public rapid chargers can cost significantly more than home charging, typically around 76p per kWh on average, with some networks charging between 55p and 92p per kWh. These higher rates reflect the convenience, speed, and infrastructure costs associated with public charging networks. Prices can also vary between different charging network providers, so it pays to compare rates before plugging in.

Strategies to reduce your EV charging expenses

Taking proactive steps can help you keep your EV charging costs in check, regardless of where you charge.

Smart charging habits

Adjusting your charging habits is one of the most effective ways to save money. Prioritise home charging during off-peak hours, especially if you are on a dual-rate tariff. Many EVs and smart home chargers allow you to schedule charging sessions, ensuring your car only charges when electricity is cheapest. Pre-conditioning your car while it's still plugged in can also save energy, as the cabin heating or cooling uses grid power rather than your battery.

Leveraging technology and tariffs

Ensure you have a smart meter installed to take full advantage of dual-rate variable tariffs. These tariffs, with their lower off-peak rates, are designed to reward flexible electricity consumption. Utilise your EV's companion app or third-party charging apps to locate the most affordable public charging points when you're away from home. Regularly reviewing your energy consumption and tariff ensures you're always on the best deal for your driving and charging needs.

EV charging vs petrol/diesel: a cost comparison

When comparing the running costs of an EV to a petrol or diesel car, electric vehicles generally come out on top. While the upfront purchase price of an EV can sometimes be higher, the "fuel" costs are typically much lower. Even with fluctuating electricity prices, charging an EV at home, especially during off-peak hours, remains significantly cheaper than filling up a traditional internal combustion engine vehicle. This cost saving, combined with lower maintenance and potential tax benefits, makes EVs an economically attractive option in the long run.
