In the long run an EV is likely to cost less than a petrol car

Just like traditional fuel engine vehicles, the cost of buying and running an electric vehicle (or EV for short) varies depending on the model, make and specifics of the vehicle – it means there's an option for everyone.

Good news – electric vehicles are likely to cost you less over the course of ownership. Electricity costs much less than buying petrol or diesel and the battery engine requires less maintenance than a fuel engine.

Before you buy an EV, you should consider the initial cost, the cost of charging and if there are any government grants or schemes to take advantage of as they encourage more people to go electric.

Some more good news for EV owners! You’ll receive plenty of benefits when driving an electric vehicle. You can be entitled to Vehicle Excise Duty discounts or exemption and also exemption from Fuel Duty. Read more information on tax benefits. You could get a discount or possibly drive in the Congestion Charge zone for free. Find out more here.

Upfront costs

The two main upfront costs of buying an EV are buying the vehicle and installing a home charging point.

Costs of charging

Charging your electric car at home is the main charging option for most EV owners. It's important to be on the best home energy tariff to keep this cost as low as possible because the cost of charging will be included in your normal electricity bill.

How much this will be depends on the amount of charging you do, the type of charger you have and also how much you use public charging.

Charging your EV will show up as part of your electricity bill – the same as charging your phone or using your lights would. You won't have a separate bill for your EV charging – it's combined into your normal electricity bill.

Electric vehicle grants and schemes

The UK Government want more people to go electric and are supporting people to afford the switch. To help with the upfront costs of buying an electric vehicle and installing a home charging point, there are a few different government grants available.

You can sign up for the UK Government's EV home charging scheme (EVHS) or find out more about eligibility and the application process.

You can also get a discounted price on the upfront cost of buying a new EV with the government plug-in grant.

Like any schemes or grants this will be subject to change. Check out the latest developments on the website.

Businesses could save money by switching to an electric fleet

35 cities will be introducing diesel charges from 2019. Plus 10 cities across the UK have been awarded a share of £14m to fund around 400 rapid and 150 fast charge points, enabling the take-up of around 23,000 electric taxis nationally.

Are electric cars more expensive to insure?

They shouldn’t cost more to insure than a traditional petrol or diesel car. Insuring an electric car has been tricky in the past because insurers didn’t have any historic data on how they perform and what they cost to repair - but now they do.

As some insurers are still unfamiliar with EVs there can be a premium to insure them. So make sure you shop around for the best possible deal.
