RAC says the increase is down to the 'soaring costs' of wholesale gas and electricity.
The U.K. wants to stop the sale of new diesel and gasoline cars and vans by 2030. It will require, from 2035, all new cars and vans to have zero-tailpipe emissions.
With more EVs set to arrive on Britain's roads in the years ahead, the RAC is backing calls for a sales tax cut in electricity sold at public chargers in order to redress what it sees as an imbalance between public and private charging.
In a statement sent to CNBC, a government spokesperson said EVs continued to "offer opportunities for savings against their petrol and diesel counterparts with lower overall running costs thanks to cheaper charging, lower maintenance costs and tax incentives." "We want consumers to have the confidence to make the switch to cleaner, zero emissions cars, and that is why we continue to support the growth of our world-leading charging network and have pledged £1.6bn since 2020 to delivering chargepoints across the country," the spokesperson added.
With European economies facing an energy crisis and soaring prices over the coming months, there have been concerns in some quarters that the increasing cost of charging an EV will disincentivize uptake among consumers., the head of equity strategy at Saxo Bank said "the cost advantage for electric vehicles versus a gasoline car" was "fast diminishing" in Europe.
