A Basic Command Unit (BCU) is the largest unit into which territorialBritish Police forces are divided. This may actually be called a BCU or may have another designation, such as LPU or LPT, Division or Area. There are 228 BCUs (including those with different titles such as division etc.) in England and Wales.
Most forces are divided into at least three BCUs and some have many more. Most BCUs are further subdivided into smaller units. The BCU is usually commanded by a Chief Superintendent.
Warwickshire Police has abolished BCUs, the first British territorial police force to do so. The force is now divided directly into five Districts, each headed by a Chief Inspector. These were formerly grouped into two Areas (BCUs), North and South, each headed by a Chief Superintendent.
