When businesses hire security guard services in London, there is often an assumption that guards will “handle everything security-related”. In reality, professional guarding services have a clear scope of responsibilities, and understanding what is included — and what is not — is essential for setting expectations and avoiding gaps in protection.
This guide explains exactly what professional security guards do, what guarding services typically exclude, the different types of manned guarding available, and when on-site security is essential for your business.
Core Responsibilities of Professional Security Guards
Professional manned guarding services are designed to provide a visible deterrent, maintain control of a site, and respond appropriately to incidents.
Access Control and Site Monitoring
Security guards are responsible for:
- Controlling entry and exit points
- Verifying authorised personnel and visitors
- Monitoring deliveries and contractors
- Enforcing site rules and procedures
This is a core function of on-site security for commercial premises.
Patrols and Surveillance
Depending on the contract, guards may carry out:
- Regular patrols of buildings or perimeters
- Internal and external site checks
- Identification of security risks or hazards
Patrolling reduces blind spots and increases deterrence.
Incident Prevention and Response
Professional guards are trained to:
- Deter theft, vandalism, and unauthorised access
- Respond calmly to incidents
- Escalate issues according to agreed protocols
- Liaise with emergency services when required
Reporting and Documentation
Guards provide:
- Incident reports
- Daily activity logs
- Shift handover notes
- Evidence support following incidents
Accurate reporting is critical for accountability and compliance.
What Guarding Services Typically Exclude
While commercial security guards play a vital role, there are limits to their responsibilities.
Law Enforcement Powers
Security guards are not police officers. They do not:
- Conduct criminal investigations
- Make arrests beyond lawful citizen powers
- Use force except where legally justified
Alarm and System Monitoring
Unless specifically contracted, guards do not:
- Monitor CCTV systems remotely
- Operate alarm receiving centres
- Replace electronic security systems
Guards work alongside technology — they do not replace it.
Technical Repairs or Maintenance
Security guards are not responsible for:
- Fixing CCTV or alarms
- Repairing access control systems
- Maintaining building infrastructure
Unauthorised Duties
Guards should not be expected to:
- Perform cleaning or reception tasks (unless part of concierge guarding)
- Carry out managerial or HR duties
- Act outside agreed SOPs
Clear guarding contracts prevent scope creep and risk.
Differences Between Static, Patrol, and Concierge Guarding
Not all guarding services are the same. Choosing the right type depends on your site and risk profile.
Static Guarding
Static guards remain at a fixed location such as:
- Entrances
- Reception points
- Access gates
Ideal for access control and visible deterrence.
Mobile or Patrol Guarding
Patrol guards:
- Cover larger sites
- Perform regular checks
- Focus on perimeter security
Common in warehouses, construction sites, and industrial premises.
Concierge or Corporate Guarding
Concierge guards combine security with customer service:
- Corporate offices
- Residential buildings
- High-end commercial sites
They require higher communication and presentation standards.
When Guarding Services Are Essential
Professional business guarding services are particularly important when:
- You manage high-value assets or stock
- Your premises operate overnight or 24/7
- You experience theft, vandalism, or trespassing
- You need visible deterrence for staff and visitors
- You require controlled access to sensitive areas
Retail, construction, logistics, offices, and corporate environments all benefit from tailored guarding solutions.

Frequently Asked Questions
Are security guards trained and licensed?

No. Guards complement electronic systems. Alarms and CCTV enhance detection, while guards provide human judgement and response.
Can guards work overnight?
Yes. Night guards are commonly deployed for warehouses, offices, and construction sites operating outside normal hours.
Are guarding services flexible?
Yes. Guarding contracts can be scaled up or down based on risk levels, operating hours, and seasonal demand.
What’s the difference between manned guarding and mobile patrols?
Manned guarding provides continuous on-site presence, while mobile patrols involve periodic site visits across multiple locations.
