Electric car public charging costs | RAC Charge Watch | RAC Drive (2024)

Charge Watch is the RAC's initiative that monitors the average cost of charging an electric car ('EV') on a pay-as-you-go, non-subscription basis at a publicrapid or ultra-rapid charger. It tracks pricechangesover timeto make sure drivers get a fair deal.

More drivers than ever are looking to make the switch to electric vehicles in the run-up to the2030 ban on the sale of new petrol and diesel cars and vans. Yet as many as one-in-three households are likely to be unable to charge an electric vehicle at home, meaning a large number of drivers will rely on using public chargers away from home. This is why having an affordable, reliable and fit-for-purpose network of chargers across the UK is so important.

The RAC has run Fuel Watch for many years to ensure drivers pay a fair price at the pumps. Charge Watch aims to do the same for drivers of electric cars who want to pay to use the fastest public charge points without a subscription, and without having to signup to a particular operator. The RAC was also a founding supporter of the FairCharge campaign.

The UK has a myriad of charging point operators which run chargers of differing speeds, from so-called 'fast' devices to 'ultra-rapid' devices which can deliver charges up to 350 kilowatts (kW). RAC Charge Watch focuses only on pricesat rapid and ultra-rapid chargers, as increasingly these will be the chargers drivers rely on to complete long journeys or to run an EV if they aren't able to charge at home. The importance of rapid chargers was emphasised by the Government in April 2022 when it announced plans to ensure these chargers are working for drivers 99% of the time.

Charging prices have increased since September 2022, in line with the rise in wholesale electricity costs in the UK, although prices began toplateau through late 2023.

Below are the average costs as analysed by the RAC, in pence per kilowatt hour (ppkWh):

As manufacturers of electric cars only recommend rapid charging to 80% to maximise the charging rate and protect the health of the battery, RAC Charge Watch calculates the cost of charging from 0% to 80%. While electric car battery sizes vary, weusea 64 kilowatt hour (kWh) battery for the basis for all cost calculations as it is an average of several popular family-sized models on sale in the UK today. Rapid charging a 64kWh battery to80% requires51.2kWh of electricity. At a price of 77.38p per kWh for a rapid charge in March 2024- the latestmonth the RAC collected data -the cost of an 80% charge wasaround £40. This would give the driver a range of around 167miles.

Below are the average costs since summer 2022:

To help put the cost of a rapid charge into context, it's also possible tocalculatean average cost per mile of driving an electric car compared to a per-mile cost of driving a petrol or diesel car.

Electric car calculations arebased on a car'sassumed efficiency of 3.5miles per kWh (as with miles per gallon in a petrol or diesel vehicle, an EV's efficiency is affected by a range of different factors including driving style). Petrol and diesel calculations are based on acar averaging 40 miles per gallon, equivalent to 8.81 miles per litre, with average per litre costs taken fromRAC Fuel Watch.

As of January 2024, the cost of only charging an EV at a rapid charger was the equivalent of 21p per mile, compared to 16p for a petrol-powered vehicle.

The cost of charging at home remains significantly cheaper than using a rapid or ultra-rapid public charger, even with high domestic energy prices.

From October 2023,a driver fully charging an electric car with a 64kWh battery (from 0% to 100%) at home pays a maximum of£17.28, based on Ofgem's capped rates for standard variable domestic electricity tariffs. Some energy providers also have tariffs that offer lower overnight prices to help keep the cost of charging a car to a minimum.

As well as taking the lead when it comes to supporting drivers in moving to electric vehicles, the RAC wasa founding backer of the FairCharge campaign, led by transport campaigner and automotive journalist Quentin Willson. FairCharge exists toto speed up the switch to electric cars by removing many of the barriers currently facing drivers, and to push key EV issues to the forefront of the political agenda.

In September 2023, RAC and FairCharge launched the UK's first public electric vehicle charging charter, setting out expectedstandards for charging in order to give drivers - both today and in the future - the best possible experience.
