Energy suppliers are looking to offer special tariffs for electric vehicle (EV) owners as demand for EVs increases in the UK.

Ovo Energy said it is “absolutely looking at tariff propositions for EV drivers”, while big six suppliers EDF, Scottish Power and Npower are joined by independent supplier First Utility in saying they are “monitoring the EV market closely.”

The comments follow Tesla’s UK and Ireland country director Georg Ell saying he is “engaged in conversations with an energy supplier” to try and convince them to offer a tariff for EV drivers who inevitably consumer more energy at home by charging their vehicles.

It was reported by edie.net that he said energy suppliers need to “speed up with the transition.”

However independent supplier Ecotricity already offers an annual discount on its own Green Electricity tariff of £40 a year for EV drivers, a discount equivalent to at least 1,000 “free miles” a year.

Both big six suppliers Npower and British Gas introduced a special EV tariff in 2011 in anticipation of the growing EV market, but were forced to scrap them on the introduction of the four tariff cap in 2014.

The competition and markets authority has proposed scrapping the cap in its provisional remedies, which would allow energy suppliers to reintroduce specialised tariffs.
