Ecotricity is set to begin charging customers using its ‘Electric Highway’ car charging network.

A rapid charge of 30 minutes will cost £6 for users who are not ­Ecotricity domestic energy ­customers.

The Electric Highway network has 296 chargers, of which 276 are rapid ­chargers, across Britain. Ecotricity said network usage trebled in 2015.

In its busiest month, May 2016, the Electric Highway provided 347.3MWh of electricity through 43,211 separate charges.
