Schedule 7 to the Terrorism Act 2000 is a port and border power that allows examining officers to stop, question and, where necessary, detain individuals travelling through ports, airports, international rail terminals and the Northern Ireland border area in order to determine whether they are or have been involved in terrorism. As such, detentions recorded following Schedule 7 examinations relate to the exercise of these border examination powers.

1,487 detentions were made under Schedule 7 in the year to June 2026. Further information on examinations and resultant detentions under Schedule 7 to the Terrorism Act 2000 is published in Table S.03a ('Number of examinations made under Schedule 7 of the Terrorism Act 2000, with grouped self-defined ethnicity breakdowns').
