Published figures on people detained in the United Kingdom solely under Immigration Act powers include those held in short term holding facilities, pre departure accommodation and immigration removal centres. Figures exclude those held in police cells, Prison Service establishments, short term holding rooms at ports and airports (for less than 24 hours), and those recorded as detained under both criminal and immigration powers and their dependants. The period of detention starts when a person first enters the Home Office detention estate.
If the person is then moved from a removal centre to a police cell or Prison Service establishment, this period of stay will be included if the detention is solely under Immigration Act powers.
