The new energy price cap in October could make charging an electric vehicle more costly than filling a car up with petrol.
The RAC has issued a warning to motorists that electric vehicles will be pricier to maintain than petrol cars once the new cap comes into effect on October 1.
According to the insurance company, the price of a full charge for an electric vehicle with a 64-kilowatt hour battery will be £33.80 — up from the current cost of £18.37.
