The number of electric charging locations will outnumber PFSs within four years, according to Nick Bywater, associate director of Christie & Co. He says that while sales of EVs currently represent only a small percentage of new car registrations, he believes it is the lack of public rapid charging infrastructure that is one of the barriers to their use.

"Considering the 23% increase in electric charging locations in 2017, the number of charging locations will outnumber petrol filling stations within four years," he said.
