British Gas and SSE to purge petrol and diesel from fleets by 2030

Two of big six energy companies sign up to pledge organised by the Climate Group

Two of Britain's biggest energy suppliers are accelerating the drive towards greener vehicles by pledging to replace their existing fleet of vans with all-electric models by 2030.

British Gas owner Centrica and SSE have committed to switch to electric cars and vans a decade ahead of the government's ban on the sale of new combustion engine vehicles.
