Ovo is launching a tariff enabling EV drivers to pay just 1p per mile, and it will be available tomorrow.
The “type of use” tariff will charge users less for electricity used to charge their cars.
This is not the only deal on the market encouraging the switch to electric cars.
Mitsubishi has discounted the Outlander petrol hybrid model by £4,000.
The car can manage 32.5 miles per gallon and only produces 196 g/km of CO2 emissions.
This puts it into one of the lowest car tax brackets.
Those who purchase the Outlander PHEV benefit from extra incentives including 10,000 miles of free electricity when customers switch to OVO Energy.
Mitsubishi said the vehicle will be available under finance, with motorists paying £289 a month for 49 months.
Electric cars are set to be the future, as the Government plans on banning the sale of new petrol and diesel cars by 2030.
Speaking on Sky News, Secretary of State for Business, Energy and Industrial Strategy, Kwasi Kwarteng, spoke of the role electric cars will have in reducing emissions.
He said: “It is not something that will happen overnight, it’s a gradual process.
“If you take up an electric vehicle now, it’s considerably cheaper than it was a few years ago.
“We’re trying to roll out charging points and we’re trying to affect that transition.”
