What Does a Security Guard Do?, planned around the premises.
A security guard's duties should come from the risks and operating procedures of the premises. Depending on the assignment, the role may include access control, visible presence, patrols, visitor records, incident response and shift handovers.
For organisations defining or reviewing an on-site security guarding requirement.
Every enquiry starts with the actual building or site. We review the reason for cover, the duties required, proposed staffing, operating hours and the instructions that personnel will need to follow. This avoids treating a temporary fire safety or security assignment as a generic guard booking.
When this service may be considered
A guarding role needs clear duties
Reception and security responsibilities overlap
Incident thresholds are unclear
A tender needs measurable deliverables
These examples are not a substitute for competent assessment. The responsible person and their appointed professionals remain responsible for determining the appropriate fire safety, evacuation or security arrangements for the premises.
Duties defined by the premises
Security guards may control entrances, verify visitors, record deliveries, patrol agreed areas, monitor specified systems and respond to incidents. The exact role depends on the site's risks, people, operating hours and client procedures. Written instructions should define what the guard must do and what falls outside their authority.
A construction guard may focus on gates, vehicles, plant and perimeter. A residential guard may require professional resident-facing conduct, while a commercial officer may support reception and out-of-hours access. One generic list should not be copied across materially different properties.
Authority, licensing and emergencies
Licensing follows the activities performed. Personnel carrying out licensable guarding work need the appropriate current SIA licence, but that does not grant unlimited authority. Search, exclusion, key use, CCTV, emergency and police-contact procedures should be established by the client and provider.
Guards should protect their own safety and follow the site's emergency procedures. They are not expected to investigate hazards or confront situations beyond training and instruction. Immediate escalation takes priority, followed by a factual written record.
Patrols, records and handovers
Patrol routes should identify locations, timing, access and exceptions. Electronic checkpoints can support evidence, but supervision must examine missed points and unusual patterns. Incident reports should state facts, actions, contacts and follow-up without unsupported conclusions.
Every shift needs a handover covering incidents, open actions, access, equipment and temporary instruction changes. Performance can then be reviewed against attendance, patrol completion, reporting and corrective action. Metrics measure service delivery, not the legal compliance of the premises.
