The cost of charging an electric car

How switching to an electric car could save you money - compare the cost of electric vs petrol.

How much does it cost to charge an electric car?

Whilst the initial spend on an electric car is still more expensive than a petrol or diesel car, the cost of running them is significantly lower, with the average petrol and diesel cost over £1.63 per litre1; more than the average cost of electricity at 34p/kWh2. Plus, if you get your energy from E.ON Next you can rest assured that you're powering your car with 100% renewable electricity.

EV vs Petrol - Compare the costs

It costs £12.00 to drive 100 miles in an electric car

The average electricity cost in the UK is 34p per kWh.1

It costs £18 to drive 100 miles in an average petrol car

The average cost of petrol is £1.631

An electric car costs £6 less than the average petrol car for every 100 miles

Electric car running costs

Charging at home is cheaper and more convienient than filling a conventional car at a petrol station.  With the average UK electricity cost at 34p per kWh you could fill a Nissan leaf with a 40 kWh battery for as little as £14.1 That would give you a range of 151 miles. 

Charging with a specific EV electricity tariff could save you even more as they're designed to give you cheaper energy costs at night meaning you can plug in when you go to bed and benefit from the cheaper price overnight. 

3 cost benefits of driving an EV

Tax free

For drivers of Battery Electric Vehicles (BEVs), that's purely electric cars rather than plug-in hybrids, road tax is absolutely free. Even if you have a plug- in hybrid car your road tax will be less than a petrol or diesel car. 

Re-sale demand

Between July and September 2021, 83,000 ultra-low emission vehicles were registered in the UK.2  The increased demand for EV’s is keeping the re-sale value high, meaning more money in your pocket when you sell.

Government incentives

You may find that you're eligible for grants and incentives that aim to make home chargers more affordable and you could even help your workplace to benefit with workplace charging incentives and company car tax relief for EV's.

The cost of public charging...

The cost of charging on the road can vary, based on the speed of the charger. As an example, you could charge a Nissan Ariya Evolve 87kWh Auto with a 50kW charger in an hour for just £23.3

There are also still many free EV chargers available across the UK. This is a great incentive to switch to electric. Most of them can be found in supermarket car parks, so you can charge whilst you do your weekly shop. You can locate public charge points on the E.ON Drive map.

Public charging speeds explained

Public chargers come in a range of speeds, slow, fast, rapid and ultra-fast like our network of chargers across Europe. 

Fast

Fast chargers are the most common public chargers found in supermarkets and public car parks. They usually give you a charging power of 7kW or 22kW.

Slow

Slow chargers will give you a charging power of 3kW.

Rapid

Rapid chargers will give you a charging power of 50kW.

What are the benefits of driving an electric car?

The environmental benefits of driving an electric vehicle are huge. Unlike petrol and diesel cars EV's don't release carbon into the atmosphere through exhaust fumes, helping to keep the air clean where you live. You'll also have a quieter drive in an electric car, and you may even benefit from government grants and free parking initiatives. 

We've pulled together a list of benefits that driving an EV can provide and with UK cities investing more and more in charging infrastructure you can take advantage of a range of funding and parking schemes aimed at electric car drivers. 

Environmental

Electric vehicles don't have a tailpipe releasing carbon exhaust fumes into the air, so by driving an EV you're helping to reduce air pollution and combat climate change.

Experience

Electric cars offer a quieter, smoother ride. You can use a home charger and they're automatic too so you can just put your foot down and enjoy your surroundings.

Economic

Although the initial purchase price of electric vehicles is high, the running costs are much lower than petrol or diesel cars.1 The electric car tax benefits reduce costs too.

What's the battery capacity of an electric vehicle?

The idea of powering your car with a battery is a new one to most of us. Electric car batteries can be huge but they're essentially lithium-ion batteries similar to those you'd find in your mobile phone or tablet. Depending on the size of your EV's battery and the power of your charger it could take anywhere from 30 minutes to 12 hours to fully charge your vehicle. Understanding the battery capacity of your electric car will help you plan your journeys effectively.
