Energy supplier E.On has launched what it says is Britain’s cheapest EV tariff.
From October 27, the operator has cut prices on two of its EV-specific tariffs – Next Drive Smart and Next Drive Fixed.
The changes bring the overnight cost of energy on Next Drive Smart down from 8p/kWh to just 6.5p/kWh – the cheapest overnight rate currently on offer.
The reduction means owners of a Renault 5 E-Tech with its 52kWh battery will pay just £3.38 to fully charge their car. With an official range of up to 259 miles that means running costs of just 1.3p per mile.
At the other end of the EV scale, the 500-mile BMW iX3 will cost £7.06 to fully charge its 108.7kWh battery at the overnight rate, equating to running costs of around 1.4p per mile. That’s less than a tenth of the average petrol running cost, which due to the ongoing fuel crisis sits at 18p per mile.
E.On says that compared with the current standard domestic price cap rate, the changes will see EV drivers save up to £475 per year.
It’s worth noting, however, that charging outside of the 12am-6am off-peak window will see drivers pay E.On’s “day rate” of 34p/kWh – 8p more than the standard variable rate.
Alongside the changes to the dynamic Next Drive Smart rate, the supplier has also cut the cost of its Next Drive Fixed tariff to 8.5p/kWh overnight. E.On says this less flexible rate could still save drivers up to £428 per year compared with the current price cap.
Customers signing up for either tariff also get a free one-year subscription to Zoom EV, which provides benefits and discounts including public charging, parking and car hire, as well as a one-off donation to the Woodland Trust to contribute towards restoring the UK’s ancient woodland.
With fuel prices still hovering at nearly £1.80 per litre for petrol and close to £2/litre for diesel, interest in EVs appears to be soaring as drivers switch on to the massive savings in running costs for those who can charge at home.
