Twenty-one of the 28 buses are currently in service and the remaining seven will operate early next year.
The new fleet is serving smaller local estates and communities, with the compact buses specifically designed for narrower roads in more rural and outlying areas.
John Cliffe, head of operations at Mellor, said: “These vehicles not only improve access to public transport by offering enhanced operational efficiency through their compact size and low carbon emissions, but they also play a crucial role in connecting communities and reducing social isolation.”
