Home charging costs drop 12% but public charging prices rise, finds AA
Costs for charging an EV at home fell by 4p per kWh in July but public flat rate charging prices increased, according to the latest AA EV Recharge Report.
On 1 July, the new Energy Price Cap fell from an average of 34p/kWh to 30p/kWh. However, all flat-rate public charging costs rose by at least a penny compared to June, with slow rate on average rising by 4 pence to 48 p/kWh due to a big rise in one city.
Slow charging in residential areas through lampposts actually remained largely static across the country – but due to the council-announced increase in Brighton and Hove (up 56% from 39p/kWh to 61p/kWh), the average kerbside cost across the country went up 4p per kWh
Meanwhile, all peak and off-peak rates of charging in the public realm remained static offering some comfort to EV owners.

The data also reveals that flat-rate slow charging is now at its highest point this year. With domestic energy prices falling and OFGEM reporting that wholesale electricity prices are down considerably from the same time last year, EV drivers may feel disappointed that public realm charging has not fallen.
Jack Cousens, head of roads policy for the AA, said; “The majority of EV owners have their own dedicated charging source and would have reaped the benefits of the drop in the Energy Price Cap when charging at home.
“However, that benefit may have been missed completely for those who are solely reliant on the public network. While wholesale electricity costs have dropped considerably from last summer, some networks increased their prices.”
He added: “With the Competition and Markets Authority and government keen to keep an eye on pump prices, there is a strong argument to consider mirroring their activities for EV charging costs in the public realm.”
