How much does it cost to charge an electric car?

The good news is that the government is keen for motorists to go green and is offering generous subsidies, so if you have a unit fitted by an authorised installer, then the Office of Zero Emissions Vehicles (OZEV) will stump up 75% of the overall cost up to a maximum of £350. Of course, the prices vary, but with the grant, you can expect to pay around £400 for a home charging station. Better still, if you’ve still not bought your EV, bear in mind that a number of manufacturers are offering a free wallbox and installation when you buy one of their electric models.

The not so good news is that the Government is pulling the plug on the funding for this scheme for homeowners that reside in single unit properties (bungalows, detached, semi-detached and terraced housing) in April 2022. That means to still qualify for the grant you’ll need to have the unit installed before 31 March 2022 and have submitted all the relevant paperwork to OZEV by 30 April 2022. On the plus side, you’ll still be eligible for the grant if you rent this type of property or if you’re a homeowner that lives in a block of flats.

Also, bear in mind that, if you are a homeowner in a single unit property and still haven’t bought your EV then, a number of manufacturers are still offering a free wallbox and installation when you buy one of their electric models.

How much will it cost at a public charging station?

Again, this is dependent on your car and the way you use it, because there are numerous options when it comes to public charging stations. For instance, if you only need to charge when out and about infrequently, then a pay-as-you-go method is possible, costing between 20p and 70p per kWh, depending on whether you’re using a fast or rapid charger, the latter costing more to use. Recent arrival Instavolt works on this principle, requiring nothing more than contactless payment as when you need to top up, Others providers will charge an hourly rate (effectively a parking charge) plus a kWh charge for electricity consumed.

If you travel further afield more frequently, then providers such as BP Pulse offer a subscription service with a monthly fee of just under £8, which gives you discounted rates on many of its 8,000 chargers, plus free access to a handful of AC units. You’ll need an RFID card or smartphone app to access them, but once connected you can charge at 50kW 52p per kWh and 55p per kWh for the 150kW chargers. Better still, the service is currently offering a month's subscription free plus £45 of credit.

It’s also possible to use many of the chargers on a pay-as-you go basis with a contactless bank card, with a rate of 26p per kWh for 7kW AC chargers, or 33p and 44p per kWh for its 50kW and 150kW chargers respectively.

Rival oil company Shell has its Recharge network which has been rolling out 50kW, 150kW and 175kW rapid chargers at its filling stations across the UK. These can be used on a contactless pay-as-you-go basis on a flat rate of 79p per kWh for it 85kWh Rapid chargers and 85p per kWh for its 150kW and 175kW Ultra Rapid chargers, although it’s worth noting there’s a £20 pre-authorisation requirement on your card. This price remains unchanged if you sign up to the Shell Recharge account, which bills you monthly for your use but also allows you to use over 250,000 chargers from over 250 providers across Europe.

It’s also worth bearing in mind that some hotels and shopping centres offer free charging to customers. The widespread use of smartphone apps for all providers makes it easy to see where the charging points are, how much they cost to use and and whether they’re free, so you can easily tap into a provider that suits your needs and budget.

Many manufacturers also offer simplified charging by giving access to numerous providers under their own charging scheme. For instance, Audi’s E-tron Charging Service account gives access to nearly 20 different energy firms, while all new E-trons come with a voucher that’ll cover the first 1000 miles worth of charges for free.

Tesla owners get their own dedicated rapid-charging Supercharger network, plus a number of Destination fast chargers at locations such as hotels. Owners of a Tesla Model S or Model X registered before 2017 are eligible for free charging, while owners of later cars will currently be charged at a rate of 28p per kWh, although that varies from site to site so you'll need to check your Tesla App for the costs at a specific location. Bear in mind, however, that Tesla charges ‘idle fees’ if you remain parked-up once your car is charged. If the Supercharger station is over 50 percent full then you’ll be charged 50p for every minute you’re parked in a fully charged car, which rises to £1 if the station is completely full.

Tesla has recently announced that it will soon make its Superchargers available to owners of other brands of EV. It’s likely that you’ll be charged more than Tesla drivers to use them, with drivers of the slowest charging vehicles forking out the most as a way to dissuade them from spending too long plugged in.

How much does it cost for motorway charging?

You’ll pay a little more to charge at a motorway service station, largely because most of the chargers there are fast or rapid units. Until recently, Ecotricity was the only provider at these locations, with around 300 chargers available, but it has now been joined by companies such as Ionity. In the case of Ecotricity, it has recently sold its Electric Highway network of chargers to Gridserve, which has promised greater investment and more 350kW rapid chargers, including the 12 units just installed at Rugby Services in Warwickshire.

Over the rest of the Electric Highway network here’s the existing choice of both AC and DC charging options, all with a 45-minute maximum use time. There are only a handful of the AC fast chargers left, but they are still free to use with an Ecotricity RFID card. The rapid DC chargers offer 120kW, 180 kW or 350kw charging and can be all be used on a pay-as-you-go basis for 66p per kWh at both its motorway services locations, which driops to 64kWh at its Gridserve Forecourts, which are essentially standalone hubs of main trunk roads and provide amenities such as cafes and newsagents. The firm also recently slashed its pre-authorisation requirement from £20 to £1.
