More than half of all new registrations - around 1.3 million a year - will be made up of electric vehicles (EV) by 2027, according to industry experts.
This year started with the best period for EV uptake since records began, with thousands of people purchasing a green motor.
Trends show that the country is on the right road to meet government forecasts for all new cars and vans to be electric by 2040.
The figures were revealed in a report by Go Ultra Low, a government and industry-backed campaign.
The launch of the plug-in car grant in 2011 sparked the growth of the vehicles’ popularity.
Thousands of electric cars have been registered every year since, including more than 28,000 last year.
Government grants are currently available to help cover the cost of a new electric car or van, as long as it meets certain conditions.
Poppy Welch, head of Go Ultra Low, said: “The huge interest in electric vehicles and their subsequent rapid rise in uptake has been spectacular so far, with more than 60,000 EVs registered in the past five years.
“These rises are just the start of the electric revolution as Go Ultra Low analysis suggests that electric vehicles could dominate the new car market as early as 2027.”
Car manufacturers are introducing more and more electric and plug-in hybrid models and the popularity of these motors is poised to overtake petrol and diesel models.
Many companies are jumping on the bandwagon, including Volkswagen, which has announced plans to release a fleet of electric-powered cars by 2025.
More than 30 electric-powered vehicles could be introduced by VW, with the company predicting to sell between two and three million a year.
