Last year councillors declared a climate emergency and made a commitment to ensure its activities and operations are carbon neutral by 2030.
The arrival of the new electric vans replace six diesel vans and will help to reduce its emissions by around 6 tonnes per year.
Each will be driven by the highways and enforcement teams for duties around the borough.
Councillor Carolyn Healy, cabinet member for climate change, said: “We’re really pleased to be able to start replacing the diesel vehicles that currently make up our fleet with new environmentally friendly, economical electric vehicles.
“These new vans will ensure that we are fulfilling our promise to work to reduce the Council’s carbon emissions over the next decade.
“We are already looking to add a further three electric vans to the fleet and will continue to replace the older vans as needed.”
Additionally, the council is looking to improve the network of electric vehicle charging points across the borough soon.
