What does venue security involve?

A venue is the one place where every security problem turns up eventually: the queue that will not move, the guest who should not be inside, the fire exit someone has propped open with a keg. Venue security is the plan that deals with all of it before it becomes a story.

In short, it involves five things: knowing your safe capacity and keeping your exits clear, controlling who gets in and what they bring, putting the right licensed people at the right points, meeting the conditions on your premises licence or temporary event notice, and having procedures your staff can follow if something serious happens. The rest of this guide takes each in turn, for bars, clubs, halls and event spaces in London and the Home Counties.

This is general guidance, not legal advice. Your licence, your risk assessment and your local authority decide what applies to your venue.

What does venue security involve?

Layers, planned before the doors open. The UK’s protective security guidance, published by the police through ProtectUK, says that to deliver protective security effectively a security plan is essential along with a full risk assessment. It adds that it is important to identify an individual responsible for security. That is the starting point for any venue: one named person, one written plan, and one risk assessment that the plan answers.

The same guidance says effective physical security is best achieved by multi-layering different measures, and sums up the core principles as deter, detect, delay and initiate an effective response. For a venue that means an entrance that is obviously watched, a search policy that finds what it should, a layout that slows anyone heading somewhere they should not be, and a team that knows what to do when it happens. Our event security guards are the visible layer; the plan behind them is the part most venues skip.

Who is responsible for security at a venue?

The person running the event and the venue, together. The Health and Safety Executive says that as an organiser you must, as far as reasonably practicable, ensure the safety of visiting crowds. It also notes that control of a venue may be shared with venue management, and that if so the respective responsibilities should be clearly defined and assigned.

In practice that means writing down who owns each decision: who sets the capacity, who briefs the door team, who can stop entry, who calls the police and who signs the incident log. Picture a hypothetical: a 400-capacity music venue in east London hires out its main room for a private launch. The venue keeps responsibility for the building, the exits and the licence conditions; the hirer owns the guest list and the running order; the security team is briefed by both before doors. Agree that split in writing the week before, not on the night.

How does capacity shape venue security?

Capacity is the first security decision, not the last. The HSE’s guidance on venue and site design says the capacity of a venue depends on the available space for people, and that the limiting factors are often the emergency exits and the audience circulation capacity of the venue. It also warns organisers not to create pinch points where channelling the public could lead to dangerous overcrowding during emergencies.

So venue security starts with a number: how many people the exits and the floor can safely take, which is often lower than the number the bar would like. Everything else follows from it: a clicker count on every entrance, a running total the supervisor can see, a plan for what happens when the number is reached, and a one-in-one-out policy that the door team actually holds. Our crowd capacity calculator gives a first estimate from the floor area; the fire risk assessment and the licence give the figure that counts.

Which venue security roles need an SIA licence?

Anyone who decides who gets in or who leaves. Government guidance on SIA licensing defines manned guarding as including guarding premises against unauthorised access or occupation, against outbreaks of disorder or against damage. It says you need a door supervisor licence if you guard licensed premises against damage, theft, unauthorised access or disorderly behaviour. It also warns that if you work in the private security industry without an SIA licence you may be breaking the law.

The line that matters for venues is between stewarding and security. The same guidance says you do not need a licence to check people have paid for entry or have an invitation, or to perform stewarding duties such as directing people to their seats, toilets or first-aid facilities. But if you then refuse them entry and/or make them leave, you will need a licence. Door supervision at a licensed premises is one of the activities where a licence is needed even for in-house staff. Every officer we deploy is SIA-licensed, and our door supervisors hold the licence the role requires.

What do your licence conditions say about security?

Read them before you book anyone. A premises licence often carries conditions about door staff, CCTV, searches and incident records, and the door team should know every one of them. If your venue is not licensed for what you are planning, the route is a temporary event notice. Government guidance says you need one to carry out a licensable activity on unlicensed premises in England or Wales. The event must have fewer than 500 people at all times, including staff running the event. You must apply at least 10 clear working days before your event.

The police can object to a notice if they think the event could lead to crime and disorder or be a threat to public safety, which is why a credible security plan helps the notice through. The guidance also says you must display a copy of the notice where it can be easily seen. Treat the licence or the notice as part of the security brief: the door team should know the closing time, the age policy, the capacity figure and any condition about searches or door numbers before the first guest arrives.

What does Martyn’s Law ask of venues?

Procedures first, and no new equipment at the standard tier. The government’s factsheet on the Terrorism (Protection of Premises) Act 2025, known as Martyn’s Law, explains the two tiers. Where the number of individuals, including staff, reasonably expected to be present at the same time is between 200 and 799, the premises will be in the standard tier. Where 800 or more may be reasonably expected, they are enhanced tier premises. Standard tier premises must have public protection procedures. These are procedures to be followed by people working at the premises where they suspect an act of terrorism is occurring. The factsheet says the Act does not require physical alterations to premises or the purchase of equipment for these procedures, which are expected to be simple and low cost.

Two dates matter. The Act received Royal Assent on 3 April 2025, and the government expects the implementation period to be at least 24 months from that date. The factsheet is clear that the requirements are not yet in force and so do not need to be complied with until brought into force by regulations. The Security Industry Authority will discharge the regulatory functions when they are. A venue that writes its procedures now, and briefs its security team on them, will have nothing to scramble for later. Our Martyn’s Law readiness check walks through the questions.

What does good venue security look like on the night?

Quiet, early and written down. A good team arrives before doors for a briefing that covers the capacity figure, the licence conditions, the search policy, the layout and exits, who the duty manager is and how to reach them. ProtectUK’s guidance counts identifying and notifying supervisors or the police about suspicious behaviour among the relevant steps any site can take, so the briefing also covers what to report and to whom.

Then the night runs on a few habits. Counts at every entrance. Exits checked and kept clear. Searches done the same way for everyone. Refusals handled by a licensed officer, politely and away from the queue. Every incident, refusal and ejection written up on the night with times and the names of the staff involved, because the licensing authority, your insurer and the police may all ask for it later. Picture a hypothetical: a 300-capacity bar in the Home Counties with a Saturday club night, two door supervisors on the entrance, one officer inside on the floor, radios linked to the bar manager, and an incident log on the desk. Nothing dramatic happens, which is the point.

How do you book venue security?

Tell us the venue, the date and the capacity. Our minimum booking is four hours per guard, we accept bookings with as little as 24 hours’ notice, every officer we deploy is SIA-licensed, we carry £5 million of public liability cover, and we work across all areas of London plus the six Home Counties. We size the team to the risk rather than the head count.

Get a quote with the venue address, the licence conditions that mention security and the expected numbers, and we will come back with a plan for the door, the floor and the exits.
