What Is Physical Intervention in Security?

Physical intervention means any direct physical action taken to control a person or situation - from guiding someone away with minimal contact through to restraint – used only when de-escalation hasn't worked and there's a genuine risk of harm.

It sits at the bottom of a clear hierarchy: communication and de-escalation come first, and for most staff, that's where training rightly stops. Physical intervention is the last resort, not the default response.

There's no direct SIA requirement for standard security officers to complete physical intervention training to hold a licence, but door supervisors have needed it since 2010, given the higher likelihood of physical confrontation in that role. Many employers require it for general security staff regardless, since the same legal test of necessity and proportionality applies either way. Our Advanced Conflict Management & Physical Intervention course is built around that test, pairing the legal framework with safe, defensible technique.
