Martyn's Law for Nightclubs and Late-Night Bars
TL;DR
Nightclubs and late-night bars with 200 to 799 people inside (customers plus everyone working) fall under the standard tier of Martyn’s Law and need procedures for evacuation, invacuation, lockdown, and communication. Your busiest Saturday sets the number, smoking areas count, and a handful of 800-plus special nights a year tips the whole venue into enhanced tier. Your door team is your biggest advantage: they’re already counter-terrorism trained. Below: a worked example for a 450-capacity club.

Start with our 5-minute guide.
If your club or late-night bar regularly holds between 200 and 799 people (customers, door supervisors, bar team, DJs, cloakroom, and glass collectors combined), it falls under the standard tier of Martyn’s Law. Above 800 you’re into enhanced tier instead, which carries a heavier set of duties beyond the scope of this guide. Nightclubs sit under Schedule 1’s entertainment and leisure use; bars sit under food and drink. The duties are identical either way: public protection procedures for evacuation, invacuation, lockdown, and communication.
Late-night venues concentrate almost every hard case the Act throws up. Crowds who have been drinking, dark rooms, loud sound, and twice a night the risk sits outside the building entirely: the queue before midnight and the pavement at closing time. You also hold an advantage most venues don’t. If you run SIA door supervisors, which for most clubs is a licensing condition, you already employ people with current counter-terrorism training who manage crowds for a living.
Does Martyn's Law Apply to Nightclubs and Late-Night Bars?
Nightclubs and Late-Night Bars fall under Entertainment and leisure (Schedule 1, paragraph 3) of the Terrorism (Protection of Premises) Act 2025. If your nightclub regularly has between 200 and 799 people present at the same time, it qualifies as a standard tier premises. At 800 or more, you're into enhanced tier instead, which carries a heavier set of duties.
Standard tier means two duties: notify the SIA that you are a qualifying premises, and put public protection procedures in place covering evacuation, invacuation, lockdown, and communication.
No physical alterations. No equipment to buy. No consultants to hire.
How to Work Out Your Nightclub Capacity
Count your busiest regular night, not the average one. That means everyone working it: door supervisors, bar team, cloakroom, DJs, the promoter’s own people, glass collectors. A packed Friday or Saturday counts as happening ‘from time to time’ even if midweek is dead, so weekend numbers set your tier.
Outdoor areas on your own land are part of the premises. A smoking terrace or rear courtyard counts, and so do the people standing in it. The statutory guidance says nothing about whether a queue on the public pavement counts toward your number, so don’t agonise over it: whatever the capacity answer, your procedures have to cover an attack on the queue anyway (more on that below).
Watch the special-events trap. The statutory guidance’s own nightclub example is a venue that usually holds fewer than 800 people but tops it on five or six event nights a year. That venue is enhanced tier, because those nights happen ‘from time to time’. If you’re anywhere near the line, a hard entry cap (one-in-one-out against a set number) is both an operational tool and written evidence for your capacity assessment.

Key Challenges for Nightclubs and Late-Night Bars
Every nightclub is different, but these are the issues that come up most often:
The queue and the smoking area
Your procedures must cover an attack at the premises or in its ‘immediate vicinity’, and the guidance deliberately puts no fixed distance on that. For a club, the immediate vicinity is where your people are most exposed: the queue before midnight, the smoking area all night. The Manchester Arena bombing targeted a crowd leaving a venue, not one inside it. Your door team should own this space. Agree who watches the queue, who decides whether people outside come in or move away, and how they signal the inside of the building.
Closing time is a mass movement you run every night
Several hundred people leaving at once, into the dark, many of them drunk: you already manage this at every close. In an incident, that practised dispersal is your directional evacuation. The difference is direction. A fixed assembly point rarely works for a club crowd, so plan agreed routes away from the building instead, and have door supervisors physically lead people along them rather than pointing.
Giving instructions people can follow at 2am
Intoxicated people process instructions slowly and follow what they see more than what they hear. Music off and house lights up is step one, always: it signals that something real is happening faster than any announcement. Then short, scripted, repeated instructions from the DJ booth mic, while bar and floor staff physically walk people towards the right exit. A fire alarm on its own gets ignored in a venue where people expect noise.
Basements and multi-room layouts
Many clubs run a second room in the basement, and a single staircase is a pinch point in an evacuation. But the same room can be your best invacuation space: below street level, no external windows, solid doors. Work it out per room: the nearest way out, the safest interior space, and who is responsible for clearing it. Nobody should have to guess which applies mid-incident.
A team that changes every week
Agency door staff, guest DJs, a promoter’s own crew on hired nights: plenty of the people working your venue on a Saturday may never have seen your fire exits. A five-minute pre-doors briefing covering exits, the code word, and who is in charge fixes most of this. For promoter-run nights, put your procedures in the hire agreement so their team is briefed to the same standard as yours.
Worked Example: Nightclub Procedures
A 450-capacity nightclub on two levels: ground-floor main room with entrance lobby and cloakroom, basement second room, and a rear smoking terrace. 25 staff on a Saturday night, including six SIA door supervisors.
| Procedure | Implementation |
|---|---|
| Capacity | 475 (450 customers + 25 staff at peak) |
| Evacuation | Main entrance to the high street; rear fire exit through the terrace gate to a side street; basement fire escape stairs direct to street level. DJ kills the music and brings house lights up. Door supervisors marshal each exit and steer people away from the threat side. Cloakroom is abandoned: coats wait, people don’t. |
| Invacuation | Basement room is the designated safer area (below street level, no external windows, solid stairwell doors). If the threat is in the street, door supervisors bring the queue and the smokers inside first, then secure the doors behind them. Terrace cleared into the main room. |
| Lockdown | Front doors and lobby shutter secured by the head door supervisor; terrace gate bolted by the floor supervisor; both fire exits secured from inside (still openable from within if a fire starts); basement used as the shelter point. Music off, lights off, phones on silent, everyone moved away from the shopfront glass. |
| Communication | The door team is already on radios and the duty manager holds the channel. A code word over the radio starts the response without alarming customers. The DJ booth has a kill switch and a mic for a short scripted announcement, repeated twice. Duty manager calls 999; the head door supervisor meets police on the street and briefs them. |
| Training | Door supervisors hold current ACT certificates from their licence-linked training, so the venue briefing maps that knowledge onto this specific building. Agency staff and guest DJs get the five-minute pre-doors briefing. Laminated procedure cards behind both bars and in the DJ booth. Lockdown walkthrough before doors open, once a quarter. |
This is one example. Your procedures should reflect your specific building, layout, and circumstances. Read our full guide to public protection procedures for a detailed breakdown of what to include.

If you use SIA door supervisors, their licence-linked training already covers terror threat awareness, and licence renewals require ACT Awareness and ACT Security e-learning certificates completed within the previous year. That makes them the obvious nominated individuals for lockdown points, queue-watching, and meeting the emergency services. Two cautions. Their licence doesn’t discharge your duties: the responsible person is still the venue operator. And door staff hired in for the night don’t know your building until you brief them.
Promoter-run nights need the same standard as your own. If a promoter hires the venue, their crew is on your premises implementing your procedures, so put those procedures in the hire agreement and give their people the pre-doors briefing. The responsible person doesn’t change just because the night has someone else’s name on it.
Write procedures for your smallest crew, then scale up. A plan that needs six door supervisors fails on a Tuesday with two people in the building. If the midweek version works, the Saturday version is just the same plan with more hands.
The free ACT Awareness e-learning (45 minutes) is a good baseline for anyone who wants to go further. It covers recognising threats, suspicious items, and what to do during an attack.
Quick Checklist
- Work out your busiest-night numbers: customers plus door supervisors, bar team, cloakroom, DJs, and any promoter’s crew
- Check the special-events trap: if you’d top 800 people even five or six nights a year, you’re enhanced tier, not standard
- Include the smoking area or terrace in your procedures, and decide when you’d bring the people out there back inside
- Agree the queue protocol with your door team: who watches it, and what happens if an incident starts on the pavement
- Map exits from every room, including the basement, and plan a managed closing-time-style exit for emergencies
- Set the alert chain: radio code word, DJ kill switch, house lights up, scripted announcement
- Nominate named people for each lockdown point, with the door team covering the entrance
- Brief every shift, including agency staff and guest DJs, and keep laminated cards in the DJ booth and behind each bar
Getting Started
Compliance is not complicated. Here is what to do:
- Work out your capacity (try our free calculator). Under 200? You are not in scope.
- Write procedures for evacuation, invacuation, lockdown, and communication tailored to your nightclub.
- Make sure your staff and volunteers know the procedures. Brief them, put up posters, hand out one-page summaries.
- Keep records of what you have done and who has been briefed.
- Review at least once a year.
You can do this yourself, or use Standard Tier to document your procedures in 10 minutes, set up a training portal your staff and volunteers can access on their phones whenever it suits them, and keep a digital audit trail without chasing signatures or filing paperwork.
