629.This section sets out the requirements on a relevant offender to notify the police when there are changes to his notified details. This includes changes to any new requirements as provided for in section 108(2)(h) and (3). As a result of subsection (2)(c) an offender must notify the police, within 3 days, of the address of any premises in the UK at which he has stayed for a “qualifying period” and, which he has not already notified to the police. This place might be a friend or relative’s house or a hotel where he has stayed. A “qualifying period” is defined at subsection (9) and is a period of 7 days, or two or more periods, in any twelve months, which taken together amount to 7 days.
630.Subsection (4) allows an offender to notify the police before a notifiable event occurs. The advance notification must give a date when the event is expected to occur.
