According to new figures last month registrations od new cars fell by 2% and the Society of Motor Manufacturers and Traders (SMMT) said that 82,908 was bought in August.
Battery electric vehicles held a 36.5% share of the new car market.
SMMT chief executive Mike Hawes said: “August was the best month yet this year for EV market share and while it is often volatile due to low overall volumes, the overall trend is positive.
“September will be critical, with the new number plate factor typically driving around one in seven new car registrations for the year.
“There is now a vast choice of electric models across all segments and many consumers will also, for the first time in three years, benefit from a grant to help them switch to electric.
“With more models being added to the Government’s electric car grant each week, there is now every reason for drivers to make the switch, helping deliver both economic growth and decarbonisation.”
Ian Plummer, chief commercial officer at online vehicle marketplace Auto Trader, said: “The Government’s £650 million electric car grant helped reignite consumer interest for EVs, with advert views for new EVs under £37,000 virtually doubling overnight.
“Consumers are keeping a close watch and as more eligible models receive the grant, we’re seeing them attract more attention on our platform.”
