Do Office Buildings Need SIA Licensed Security Guards?

Direct Answer Summary: Office buildings need SIA-licensed security guards when staff carry out licensable security activities. This includes guarding against unauthorised access, theft or disorder, controlling entry, patrolling as security, or monitoring public space CCTV. If the duties are purely reception or concierge, with no security function, an SIA licence may not be required. Always check the exact duties and your local risk.

In practice, the key question is not “Is this an office?”, it is “Are people being paid to carry out licensable security activity?” If the answer is yes, the person usually needs the correct SIA front-line licence. The company supplying them must also meet its compliance duties.

Important: This guide provides practical information, not legal advice. If you are unsure, get competent security and legal guidance before deploying staff in a role that could be classed as licensable.

Quick Answer: When An Office Needs SIA-Licensed Security

You typically need SIA-licensed security in an office building when any of the following apply:

• Access Control Is Being Enforced: Challenging entry, refusing access, or controlling who can enter for security purposes.
• Security Patrols Are Carried Out: Patrolling to deter theft, vandalism, trespass, or disorder.
• Security Incidents Are Managed: Responding to aggression, removing trespassers as part of a security role, or protecting people and property.
• Public Space CCTV Is Monitored: Watching cameras covering public areas for crime prevention and public safety purposes.
• A Guarding Service Is Contracted: A third party provides “manned guarding” or security officers to protect premises.

If the duties are genuinely non-security, for example welcoming visitors, booking meeting rooms, or providing directions, SIA licensing may not be required. The main risk is “role creep”, where a receptionist or concierge is expected to act like security when a situation escalates.

What Is The SIA And What Does ‘Licensable Activity’ Mean?

The Security Industry Authority (SIA) is the UK regulator for the private security industry. It sets training, licensing, and standards for specific security roles. You can read the regulator overview here: Security Industry Authority (SIA).

The law defines licensable activity, mainly under the Private Security Industry Act 2001. In plain terms, if someone is paid to carry out certain security functions, they may need an SIA licence.

Security Guarding Vs Door Supervision Vs CCTV (Public Space Surveillance)

Most office confusion comes from choosing the right licence type. Here is a practical, office-focused breakdown:

• Security Guarding Licence: Usually covers static guarding, patrols, controlling access to premises, and protecting property in offices and commercial buildings.
• Door Supervision Licence: Typically linked to licensed premises and events. Some corporate events may also trigger door supervision requirements, depending on what the staff are doing.
• CCTV (Public Space Surveillance) Licence: Required for people monitoring public space CCTV for security purposes, such as cameras covering publicly accessible areas like building entrances and surrounding public areas.

Two people in the same office can legitimately need different licences. For example, one officer may focus on guarding, while another operates CCTV covering public areas.

Contracted Security Vs In-House Staff: Why It Matters

Whether staff are contracted or in-house can affect licensing obligations and how you manage risk:

• Contracted Security Officers: If you hire a security provider to supply guards, those individuals generally need the correct SIA licence for the duties they perform.
• In-House Staff: Some in-house roles may be exempt in specific circumstances, but exemptions are often misunderstood. If an in-house role effectively involves guarding, treat licensing as a serious consideration and check the current rules.

Even when a technical exemption exists, many organisations still choose SIA-licensed personnel. It improves competence, auditability, and reassurance for tenants, HR, and insurers.

Common Office Scenarios: Do You Need An SIA Licence?

The simplest approach is to document what the person is expected to do on shift. Include what should happen when something goes wrong. The examples below cover common office “edge cases”.

Reception/Concierge: Greeting Visitors, Passes And Signing-In

A front-of-house receptionist or concierge may not need an SIA licence if they do hospitality-style duties only. Typical non-licensable tasks include:

• Welcoming and Directing Visitors: Booking in guests and giving directions.
• Admin Support: Handling post, logging maintenance requests, and booking taxis.
• Issuing Passes As Administration: Providing pre-approved badges without making security decisions.

The role can become licensable if the person is expected to prevent unauthorised access, handle aggressive behaviour as a security function, or act as a deterrent presence.

If you want a blended role done correctly, a dedicated concierge security model can combine customer service and compliant security duties under appropriate licensing.

Access Control And Searching: Bags, ID Checks And Turnstiles

Many offices have turnstiles, barriers, and visitor management systems. Licensing risk usually depends on whether the person is:

• Observing Only: Reporting issues to management or a security team.
• Making Security Decisions: Refusing entry, challenging identity, stopping tailgating, or directing someone to leave.
• Conducting Searches: Performing bag searches as part of a security procedure.

If the role requires enforcement and intervention, it is commonly treated as security guarding activity. If your access control requirement is high, consider a dedicated manned guarding provision with clear, compliant post orders.

Patrols And Building Checks (Including Out-Of-Hours)

Patrols are a strong indicator of licensable guarding, especially when they aim to deter crime or detect suspicious activity. This often includes:

• Internal Patrols: Checking stairwells, floors, plant rooms, and fire exits.
• Perimeter Checks: Inspecting doors, gates, and delivery bays.
• Lock and Unlock Routines: Securing the building at night and opening in the morning.

If you do not need a full-time officer, a scheduled option can be more proportionate. For example, you can use security patrol contractors.

CCTV Monitoring And Control Rooms

If your office has CCTV, there are two key compliance considerations:

• SIA Licensing: If staff monitor public space surveillance for security purposes, they may need the CCTV (Public Space Surveillance) licence.
• Data Protection Compliance: You must handle CCTV lawfully, including signage, retention, and access requests.

For CCTV compliance guidance, refer to the ICO guidance on CCTV and video surveillance.

Managing Conflict And Removing Trespassers: Where The Line Is

This is one of the biggest grey areas in offices. If a person is expected to physically intervene, escort people out, or manage disorder as part of their role, the duties are likely security in nature.

Good practice is to define the following in writing:

• What Staff Should Do: Verbal challenge, calling the police, and escalating to a duty manager.
• What Staff Must Not Do: Physical removal unless trained, authorised, and operating under the correct licensing and policy.
• Use Of Force Policy: Clear rules, reporting, and oversight.

Office Events, Parties And Visitor-Heavy Days

Events can change the risk profile and your licensing needs, particularly where:

• Alcohol Is Present: Increased likelihood of disorder and conflict.
• Large Guest Lists Exist: Queue management and entry control becomes security-led.
• Late-Night Finishes Apply: Lone working risks and safeguarding become more significant.

For high-profile events, a short-term bespoke approach may be appropriate. You can explore tailored options via bespoke security.

When You Might Not Need SIA-Licensed Guards (Common Exemptions And Grey Areas)

Some office roles look like security but are facilities or customer service positions. The issue is not the job title; it is the real duties.

Purely Customer Service Or Facilities Duties (Non-Security)

You may not need SIA licensing when the role is limited to:

• Reception and Hospitality: Welcoming, meeting room bookings, and switchboard duties.
• Facilities Support: Contractor sign-in and basic building checks not linked to crime prevention.
• Reporting Only: Calling security or management rather than intervening.

Be careful with wording in job descriptions and contracts. If you describe someone as “security”, “guard”, or “responsible for preventing unauthorised access”, you may move into licensable territory.

Building Staff And Wardens: What They Can And Can’t Do

Wardens, marshals, and building staff can support safety and operations, but you should set clear limits:

• Can: Observe, report, assist with evacuations, and support visitor flow.
• Cannot (Without Correct Setup): Act as the primary security function for deterrence, enforcement, and intervention.

Legal And Business Risks Of Using Unlicensed Security

Using unlicensed staff for licensable activity creates legal exposure and commercial risk. The Private Security Industry Act 2001 sets out the legal framework.

Offences, Enforcement, And Contract/Insurance Implications

• Criminal and Regulatory Risk: Employing or supplying unlicensed operatives for licensable work can lead to enforcement action.
• Insurance Problems: Insurers may question cover if foreseeable risks are managed by non-compliant providers.
• Contractual Breach: Landlord and tenant obligations often require competent security provision and documented controls.
• Reputational Harm: Incidents involving untrained or unlicensed staff can escalate and attract unwanted attention.

How To Stay Compliant: A Simple Procurement Checklist

If you are an office manager, landlord, or facilities team, this checklist helps you procure security with fewer surprises.

Confirm Licence Type, Check The Register, And Document Role Duties

• Write A Clear Scope Of Duties: Define whether the role is customer service, security, or blended.
• Match Duties To Licence Type: Security guarding, door supervision, or CCTV (PSS), depending on activities.
• Verify Licences: Use the official service to check status: Find an SIA licence holder.
• Keep Evidence: Store licence checks, assignment instructions, and training records for audit purposes.

Example Role Wording (Office Concierge, Non-Security): “Provide a welcoming front-of-house service, manage visitor sign-in, and escalate security concerns to the nominated security contact. No enforcement or intervention duties.”

Example Role Wording (Office Security Officer): “Control access to the premises, conduct patrols to deter theft and unauthorised access, respond to security incidents, and complete incident reports in line with site instructions.”

Site Risk Assessment: Crime, Lone Working, And Response Expectations

Security should be proportionate to risk. HSE provides a useful starting point for structuring risk assessments here: HSE risk assessment guidance.

• Local Crime And Threat Profile: Consider theft, protest activity, domestic incidents, and unauthorised access risks.
• Lone Working And Out-Of-Hours: Define welfare checks, escalation routes, and minimum staffing levels.
• Response Expectations: Decide whether security should observe and report, or intervene and detain when lawful.

Policies: Incident Reporting, Use Of Force, Data Protection (CCTV)

• Incident Reporting: Ensure consistent logging, handover notes, and escalation thresholds.
• Use of Force: Set clear limits, training expectations, and post-incident review.
• CCTV Governance: Align with ICO guidance, including signage, retention, and controlled access to footage.

What Level Of Security Is Right For Your Office?

Compliance is the minimum. The goal is a safe, welcoming office with the right controls for your risk level and budget. Common models include:

Concierge Security Vs Manned Guarding Vs Mobile Patrols

• Concierge Security: Best for offices needing a professional front-of-house presence plus controlled access and incident response.
• Manned Guarding: Best for higher-risk sites, complex access control, deliveries, or multiple tenants.
• Mobile Patrols: Best for lower-occupancy sites, out-of-hours checks, and cost-effective deterrence.

FAQs

Can A Receptionist Also Be ‘Security’?

Yes, but it needs careful design. If a receptionist is expected to prevent unauthorised access, challenge people, patrol, or respond to disorder, the duties may be licensable and require the correct SIA licence. To avoid accidental non-compliance, define the role in writing. Make sure responsibilities, training, and escalation routes are realistic.

Do Night Guards Need A Different Licence?

Not usually. The key factor is the activity, not the time of day. Night guarding that involves patrolling and protecting premises is typically security guarding activity, so the appropriate SIA front-line licence is still required.

Do You Need An SIA Licence To Monitor Internal-Only CCTV?

If CCTV monitoring is genuinely internal only and not classed as public space surveillance, a CCTV (PSS) licence may not apply. However, this is a common grey area. Many office systems cover entrances and areas accessible to the public, which can change the position. Separately, you still need to meet ICO expectations on lawful use, signage, and retention.

How Do I Verify An SIA Licence Quickly?

Use the official GOV.UK checker: Find an SIA licence holder. Build it into your supplier onboarding so checks are repeatable and recorded.

Conclusion: Define The Duties, Then Match The Licence

Office buildings do not automatically require SIA-licensed guards. You need SIA licensing when people are paid to carry out licensable security activities, such as guarding, enforcing access control, patrolling as security, or monitoring public space CCTV. The safest approach is to define the role clearly, assess site risk, verify licences, and keep records.
