Allstar has highlighted the disparity between home and public EV charging rates in the first of a new series of reports.
The AllCosts report takes proprietary data from millions of fuel transactions and hundreds of thousands of on-the-road charging events throughout the Allstar network, and at-home charges, with the aim of providing businesses and fleets with real-life costs for electric, petrol and diesel vehicles on-the-road today.
It reveals that, in Autumn 2023, the average cost of home charging an EV was 28p per kWh, with a lowest recorded cost on an ultra-low tariff of 4p, while the average public charging cost was 70p, with a highest recorded cost of £1.20.
Allstar says this means running an EV on public chargers alone could be over 20 times more expensive than home charging, once variables such as time limits on ultra-low tariffs are taken into account.
It said the average rates equated to a cost of 9.7p per mile to run a family car on home charging, and 24.1p per mile on public charging, while costs for petrol and diesel equivalents were 15.8p and 15p respectively.
Allstar Chargepass UK MD Ashley Tate said: “As an industry, we are collectively migrating to alternative power for vehicles which is a huge moment in the history of mobility. With that comes plenty of questions around the various running costs, so we’ve harnessed our proprietary data to provide clear insights and help drivers get a better understanding of real-life costs of electric vehicle charging, petrol and diesel.
“For those that are opting for EVs, our inaugural edition has shown the clear cost benefits of charging at home. While we understand that this isn’t an option available for everyone, where possible drivers could make significant savings by charging at home compared to those using public charge points.
“We’ve provided the pence-per-mile figures of cars and vans in the report based on our real-life electric and fuel costs so that businesses and fleets can see our estimated indicative costs of various cars and vans models, however they choose to power them. We’ll keep a close eye on these figures and keep reporting on the latest trends.”
