Event Security in the UK: A Practical Guide to Risk, Licensing, Roles and Staffing

Planning security for an event involves more than deciding how many people should be positioned at the entrance.

The appropriate security arrangements depend on the type of event, the venue, expected attendance, access arrangements, activities taking place, operating hours and the risks that have been identified.

Different personnel can also have different functions. Security guards, door supervisors and event stewards are not interchangeable roles, and whether an SIA licence is required depends on the work being carried out and the circumstances in which it is performed.

This guide explains the main considerations when planning event security in the UK and provides a practical framework for event organisers, venue operators and private clients.

Important: This article provides general information and is not legal advice. Licensing requirements depend on the actual duties and circumstances. Where there is uncertainty about a legal requirement, event organisers should obtain appropriate professional or legal advice and check current SIA guidance.

What Is Event Security?

Event security is the planned use of security measures and personnel to help protect people, property and the event environment.

Depending on the event, this can involve:

• Access control

• Entry management

• Protection of restricted areas

• Security guarding

• Door supervision

• Crowd and queue management

• Patrols

• Incident response

• CCTV monitoring

• Protection of property and equipment

• Support for emergency procedures

• Liaison with venue management and other relevant parties

The exact combination will vary from one event to another.

There is therefore no single security arrangement that is automatically suitable for every event.

Why Event Security Planning Matters

An event organiser has responsibilities for managing health and safety risks associated with an event.

The Health and Safety Executive advises event organisers to assess crowd-related hazards, consider the number and characteristics of people attending, assess the suitability of the venue or site and establish appropriate crowd-management arrangements.

Security should form part of the wider event-management plan rather than being considered in isolation.

For example, the security plan may need to work alongside:

• Emergency procedures

• First-aid arrangements

• Fire-safety arrangements

• Venue procedures

• Traffic and transport arrangements

• Evacuation arrangements

• Crowd-management measures

• Communication procedures

• Staff and contractor management

Good planning also allows responsibilities to be identified before an event begins rather than leaving personnel to determine arrangements during an incident.

There Is No Universal Security Staffing Ratio

One of the most common questions asked when arranging event security is:

"How many security guards do I need?"

There is no single number that can be applied safely to every event.

A staffing decision should consider the circumstances of the particular event rather than relying solely on the number of guests.

For example, two events with 200 attendees could have very different security requirements if one is a daytime corporate meeting in a controlled venue and the other is a late-night event with alcohol, multiple access points and several separate areas.

Relevant factors can include:

• Expected attendance

• Venue capacity

• Event type

• Venue layout

• Number and location of entrances

• Number of exits

• Restricted areas

• Queue arrangements

• Operating hours

• Alcohol provision

• Nature of entertainment

• Audience profile

• Previous incidents

• Property or equipment requiring protection

• Traffic and vehicle movements

• Accessibility requirements

• Emergency arrangements

• Specific instructions from the venue or authorities

HSE guidance specifically recommends considering attendance numbers, audience profile, venue or site suitability, entrances and exits and crowd movement when assessing crowd-safety risks.

Why a guest-to-guard formula can be misleading

A simple ratio can give the impression that security requirements are determined only by the number of people attending.

That can be misleading.

The physical layout of a venue may mean that personnel need to cover several separate locations. An event may also require specific positions such as an entrance, backstage area, restricted-access point or car park.

The better question is therefore not simply:

"How many people are attending?"

It is:

"What security functions need to be covered, where do they need to be covered and what risks need to be managed?"

Security Guard or Door Supervisor?

The distinction between security guarding and door supervision is important.

The SIA states that an individual may need a door supervisor licence where they provide a physical presence to guard against damage, theft, unauthorised access or disorderly behaviour at licensed premises in circumstances covered by the licensing requirements.

The SIA also explains circumstances in which security guarding may require a security guard licence, including certain contracted security work at premises that are not licensed premises.

The correct licence therefore depends on the actual work being performed and the circumstances, rather than simply the event organiser's preferred job title.

Door Supervisors

A Door Supervisor licence can be relevant where the licensable activity and circumstances meet the SIA's requirements.

For example, the SIA identifies circumstances involving licensed premises where personnel are guarding against damage, theft, unauthorised access or disorderly behaviour while the premises are open to the public and alcohol is being supplied or regulated entertainment is being provided.

Security Guards

Security guarding is a separate licensable activity.

The SIA describes security guarding as involving a physical presence to guard against damage, theft, unauthorised access or disorderly behaviour in circumstances where the activity falls within the licensing requirements.

Event Stewards

Not every person working at an event is performing licensable security work.

The SIA states that certain stewarding activities do not require an SIA licence, including directing people to seats, toilets or first-aid facilities.

However, the position can change when a person's duties move into licensable security activities. The SIA specifically notes that checking whether someone has paid for entry or has an invitation does not itself require a licence, but refusing entry or making someone leave can create different licensing implications.

This is why event organisers should define duties clearly rather than relying solely on job titles.

SIA Licensing: What Event Organisers Should Check

The SIA publishes guidance specifically for buyers of event security.

Its guidance is intended to help event organisers identify roles that may require an SIA licence and understand the due-diligence checks that should be made before selecting a security provider.

Before engaging a security provider, an organiser should establish:

• What services are actually required

• Which personnel will perform each role

• Whether the role requires an SIA licence

• Whether deployed personnel hold the appropriate licence

• What checks the security provider carries out

• What insurance and contractual arrangements apply

• Who will supervise the security team

• How incidents will be reported

• How the security team will communicate with event management

The SIA also provides guidance on choosing an SIA Approved Contractor and maintains a register that can be used to check approved contractors.

An important distinction should be maintained between individual SIA licensing and the SIA Approved Contractor Scheme (ACS). They are not the same thing.

Risk Assessment and Event Security

Security planning should begin with the risks rather than with a predetermined number of personnel.

A useful assessment can consider:

People

Who will attend?

Consider:

• Expected attendance

• Age profile

• Accessibility requirements

• Whether attendees are familiar with the venue

• Whether alcohol is being served

• Whether particular groups require additional consideration

HSE guidance specifically advises event planners to consider audience characteristics, including young people and people with disabilities or learning difficulties when assessing crowd-safety measures.

Place

What is the venue or site like?

Consider:

• Entrances

• Exits

• Internal circulation

• Outdoor areas

• Car parks

• Restricted areas

• Stages

• Temporary structures

• Lighting

• Barriers

• Queuing areas

• Emergency access

HSE guidance highlights the importance of assessing venue and site suitability, including how people enter, move around and leave an event safely.

Activity

What is actually happening at the event?

A wedding, corporate event, private party, concert, sporting event and public festival can create different operational considerations.

Consider:

• Entertainment

• Alcohol

• Ticketing

• Guest access

• Performances

• VIP areas

• Valuable equipment

• Deliveries

• Vehicle movements

• Closing arrangements

Time

When is the event taking place?

Consider:

• Start and finish time

• Arrival period

• Peak attendance

• Breaks

• Departure period

• Daylight and darkness

• Late-night activity

• Staff changeover requirements

Security arrangements should cover the periods when the relevant risks exist, not simply the advertised event start and finish times.

Access Control

Access control is one of the most common security functions at events.

Depending on the event, this may involve:

• Monitoring designated entrances

• Checking access permissions

• Protecting restricted areas

• Monitoring staff-only areas

• Managing controlled entry points

• Preventing unauthorised access

The precise duties matter.

A person who is simply directing visitors may be carrying out stewarding duties. A person whose role involves refusing entry or removing people from a venue may enter a different regulatory category depending on the circumstances.

Event organisers should therefore make the intended duties clear when requesting security quotations.

Crowd Management Is Not the Same as Security Guarding

Crowd management and security are closely related but are not identical.

Crowd management involves understanding how people move through and around a venue and implementing measures to maintain safe movement.

HSE guidance highlights hazards such as crowd surging, falling, congestion, poor entrances and exits, crossflows and obstructed routes. It also recommends considering expected attendance, audience characteristics, venue suitability and crowd movement.

Depending on the event, appropriate arrangements may therefore involve a combination of:

• Event stewards

• Security personnel

• Venue management

• Traffic management

• First-aid personnel

• Emergency services

• Other specialist contractors

Security personnel should not be expected to replace every other event-safety function.

CCTV and Physical Security

CCTV can complement physical security but should not automatically be treated as a replacement for personnel.

Where CCTV is used as a licensable security activity, the SIA licensing requirements may apply. The SIA identifies public space surveillance using CCTV as one of the licensable activities covered by its guidance.

Physical personnel can provide an immediate presence at entrances, restricted areas and other designated locations, while CCTV can provide monitoring and situational awareness.

The appropriate combination depends on the site and the purpose of the security arrangement.

What Information Should You Give a Security Company?

An accurate quotation is easier to prepare when the security provider receives enough information about the event.

Useful information includes:

Event information

• Type of event

• Date

• Start and finish time

• Expected attendance

• Venue address

Venue information

• Number of entrances

• Number of exits

• Indoor and outdoor areas

• Restricted areas

• Car parks

• Access arrangements

• Venue-specific requirements

Security requirements

• Access control

• Guarding

• Door supervision

• Stewarding

• Patrols

• CCTV monitoring

• Restricted-area protection

• Incident response

Risk information

• Known concerns

• Previous incidents

• Expected disputes

• Alcohol provision

• Valuable equipment

• Any unusual circumstances

Providing this information does not mean that the client has to determine the final staffing arrangement themselves.

It gives the security provider enough information to assess the requested deployment and identify questions that may need clarification.

What Should a Security Provider Do Before Deployment?

A professional deployment should not be based solely on a booking confirmation.

Depending on the assignment, preparation can include:

• Reviewing the booking information

• Confirming the location

• Confirming duties

• Identifying relevant licensing requirements

• Establishing reporting arrangements

• Briefing personnel

• Confirming uniform requirements

• Providing site-specific instructions

• Confirming emergency procedures

• Establishing communication arrangements

• Identifying escalation procedures

For larger or more complex events, additional planning may be appropriate.

The SIA's event guidance for security suppliers covers due diligence and responsibilities before, during and after events.

During the Event

Security arrangements should remain subject to monitoring.

The event environment can change after doors open.

Attendance may be higher than expected, queues may develop, weather may change, an area may become congested, or an incident may require a different response.

HSE guidance recommends monitoring arrangements and reviewing whether risk-control measures are working and being followed.

A clear reporting structure should therefore exist between security personnel, the security supervisor where applicable and event management.

After the Event

The end of the event is not necessarily the end of the security requirement.

Depending on the assignment, personnel may need to remain until:

• Guests have left

• Restricted areas are secured

• Equipment has been protected

• Staff have departed

• The venue has returned to normal operation

• Any outstanding incidents have been reported

HSE recommends debriefing after events, particularly following significant incidents or emergencies, and using the findings to improve future arrangements.

A Practical Event Security Planning Checklist

Before requesting security cover, an organiser can work through the following checklist:

1. Event

• What type of event is it?

• When is it taking place?

• How many people are expected?

2. Venue

• Where is it?

• What is the layout?

• How many entrances and exits are there?

• Are there restricted areas?

3. Activities

• Will alcohol be served?

• Will there be entertainment?

• Are there VIP or staff-only areas?

• Is valuable equipment present?

4. Risks

• What could reasonably go wrong?

• Have there been previous incidents?

• Are there particular crowd or access concerns?

5. Security functions

• Is access control required?

• Is guarding required?

• Is door supervision required?

• Is stewarding required?

• Is CCTV monitoring required?

6. Personnel

• Which roles are required?

• Does the relevant work require an SIA licence?

• Who will supervise the deployment?

7. Communication

• Who is the event manager?

• Who should security report to?

• How should incidents be escalated?

8. After the event

• When can security personnel stand down?

• Are there closing or lock-up responsibilities?

• Does an incident/debrief process apply?

Frequently Asked Questions

How many security guards are needed for an event?

There is no universal number that applies to every event. The appropriate deployment depends on the event's circumstances, including attendance, venue layout, access points, activities, operating hours and identified risks.

Does every event need SIA-licensed security?

No. Not every person working at an event performs a licensable security activity. The requirement depends on the duties being performed and the circumstances. The SIA provides specific guidance on when event staff require a licence.

Do event stewards need an SIA licence?

Some stewarding activities do not require an SIA licence. The SIA gives examples such as directing people to seats, toilets or first-aid facilities. However, duties can become licensable when the person's role changes into a regulated security activity.

Is a Door Supervisor licence different from a Security Guard licence?

Yes. They are separate SIA licence categories, and which licence is relevant depends on the work being performed and the circumstances. Event organisers should not choose a licence category solely from the job title.

Does a security company determine the event's entire safety plan?

Not necessarily. Security is one part of wider event management. Event organisers retain responsibilities for managing the overall event and its health and safety arrangements. HSE guidance sets out responsibilities for event organisers and the wider event-management process.

Can I simply use a fixed number of guards based on guest numbers?

Guest numbers are important, but they are not the only consideration. Venue layout, access points, crowd behaviour, event activities, operating hours and specific risks can materially affect the required arrangements.

Final Considerations

Effective event security starts with understanding the event rather than choosing a predetermined number of personnel.

The most useful approach is to identify the people, property, activities, locations and risks involved; determine which security functions are actually required; establish whether those activities are subject to SIA licensing; and then develop a deployment that is appropriate to the circumstances.

For event organisers, the objective should be a security arrangement that is clear, proportionate and properly integrated with the wider event plan.

SSF Security Ltd provides professional security personnel for events, venues, businesses and private functions across London and the wider UK.

Where security cover is required, SSF can review the event information provided, discuss the required duties and propose suitable security deployment subject to the final booking and personnel availability.
