E.On has  launched a new tariff for electric and hybrid vehicle owners, using energy purchased from 100% renewable electricity and green gas. The tariff acts like an Economy 7 deal:  the night rate – when many electric and hybrid car owners will choose to charge their vehicle - is priced 33% below the day rate (described as ‘competitive’).

E.On said the tariff would save on average £261 a year when compared with an average of all dual fuel standard variable tariffs offered by the larger suppliers, and £173 a year, when compared with an average of dual fuel Economy 7 tariffs offered by the larger suppliers.

Chris Lovatt, managing director of residential at E.On, said: “For many electric or hybrid car owners, choosing the right energy tariff may be the last piece of the jigsaw in helping them lower fuel emissions and energy costs.”

The tariff is available to existing customers who own an electric or hybrid vehicle. E.On will have to fit an Economy 7 programmed smart meter to give access to the tariff.
