In the spring of 2011, Kent Fire and Rescue underwent changes to its structure, these included restructuring from three divisions to fivearea groups: North Kent, East Kent, West Kent, South Kent and Mid Kent. Each group consists of a number of clusters, which are made up of a number of certain stations where resources are locally managed. The Letter prefix for each division was dropped in the station call sign, for instance Swanley, under the old system was named as Station S31 the S standing for South Division, now it is just Station 31.
