It was established in 2019 as a merger of the previous Forest Heath District with the Borough of St Edmundsbury.
The district also contains the towns of Brandon, Clare, Haverhill, Mildenhall and Newmarket, along with numerous villages and surrounding rural areas.
Prior to West Suffolk's creation, its predecessors Forest Heath District Council and St Edmundsbury Borough Council had been working together for a number of years, having shared a joint chief executive since 2011.
The whole district is also covered by civil parishes, which form a third tier of local government.
[12] The council is based at West Suffolk House on Western Road in Bury St Edmunds.
