Energy provider Ecotricity has changed the way customers pay to charge electric vehicles at their motorway network.
In Autumn last year, the company introduced a £6 per charge fee, allowing up to 30 minutes of energy.
The new structure is a £3 connection fee, followed by a 17p/kWh cost for energy. Ecotricity customers will not pay the connection fee.
Dale Vince, Ecotricity CEO, said: "The new model that we’ve developed will give more flexibility and typically lower charging costs across all makes and models.
"The main issue we’ve been wrestling with is the fixed time period charging and the different amounts of energy that various models can use in that time - coupled with the need to reflect in the pricing model the costs of installing and running the infrastructure, not just the cost of energy.
"To better balance these issues we are separating the cost of energy from the cost of providing the service."
The changes will be introduced from June 26.
