Martyn's Law for nightclubs and live music venues
Last reviewed:
If you run a nightclub or a live music venue, there's a good chance Martyn's Law already applies to you, or soon will. This guide walks through what that actually means for a venue like yours: whether you're in scope, which tier you're likely in, whose job it is to sort it, and what you'd genuinely need to do, in plain terms rather than statute language.
How to tell if your nightclub needs a plan for Martyn's Law
Martyn's Law works on a headcount, not on what kind of venue you run.
If you reasonably expect 200 or more people on the premises at the same time, staff included, then you are in scope for Martyn's Law. The next question is what tier you belong to.
If you are between 200 and 800 people, on your busiest nights, then you are in the Standard tier.
However, if you reasonably expect 800 or more, you move into the Enhanced tier, which asks more of you.
It's important to note that count isn't your average night; it's the busiest you can reasonably expect, including predictable spikes like a big touring act or a seasonal rush. The guidance defines this as "from time to time." So, if you have one or more event a year that pushes you above 800, then you will be counted as Enhanced tier.
See the standard tier explained and the enhanced tier explained for what each level actually requires.
Nightclubs, live music venues and similar spaces fall under the Act's entertainment and leisure activities category, alongside venues like theatres, arenas and casinos. For most working nightclubs and mid-sized venues, being in scope at some level isn't really in question. The real question is which of your own capacity figures actually reflects what happens on a normal night, because that's what decides the tier.
How to count your capacity: safe occupancy vs licensed capacity
The guidance gives two nightclub examples, and they land in opposite tiers, which makes the test easier to see than most.
One nightclub sets a safe occupancy of 875. Its actual attendance, checked against twelve months of data, peaks at 725 even during its busiest periods. Because that's the number the venue can genuinely expect, not the theoretical maximum, it sits in the standard tier. A second nightclub runs to its full licensed capacity of 975, enforced on the door with a people counter, and adds its staff on top. Because that's its real, evidenced peak, it sits in the enhanced tier.
Which one you resemble depends on what actually happens at your door, not which number looks more official. If your safe occupancy or licence limit is higher than the crowd you genuinely get, the lower, evidenced figure is the one that counts, provided you can show the data behind it (para 4.25).
A worked example: The Vault has a safe occupancy of 600 and a regular Saturday peak of 340, staff included, comfortably standard tier on a normal week. Twice a year it books touring DJs and sells out at 620. Because that happens predictably rather than as a one-off, The Vault treats those specific nights as in scope, while its regular week stays well under. See how to count your capacity for the general method, the "from time to time" rule for more on recurring peaks like this, and the enhanced tier if a big enough touring act could push you past 800.
Who is the responsible person at a nightclub or music venue?
Someone has to be legally on the hook for getting this done. The law calls that person the responsible person, and for a nightclub or live music venue, it's ordinarily whoever operates the venue day to day: the person or company with control over how it's run, not necessarily whoever owns the building.
That stays true on a promoter's night, too. Hiring your venue out to someone else for the evening doesn't hand over your legal duty. The guidance is specific that the responsible person for hired-out premises stays the same, even when someone else is running the night, unless that particular event meets the full test for a "qualifying event": 800 or more people expected, open to the public, and entry controlled through a secure ticketed or paid perimeter (para 6.13). A regular promoted club night rarely meets all three. The exception is a genuinely large one-off, a touring act selling 800-plus tickets through a controlled door, where the promoter running that specific event could become responsible for it, in the same way a hirer taking over a village hall for an 800-person fundraiser becomes responsible for that event. Outside that specific case, contracting out ticketing, security or promotion to someone else doesn't move the duty onto them.

What you'd actually have to do
Once you know you're in scope, the law asks for two things, and neither is complicated on its own.
The first is a one-time notification: telling the SIA, the regulator for this law, that your venue exists and falls under the Act. It's a registration, not an application. There's no approval to wait for and no fee. The SIA hasn't yet opened the portal to do this or confirmed the exact timing, so there's nothing to act on yet, but nothing to prepare for beyond the basic facts about your venue either.
The second is having a plan for four kinds of response, each covering a different way people might need to move or be told what to do if something goes wrong:
- Evacuation. Getting people out of the building and away from danger.
- Invacuation. Moving people to a safer space inside, rather than out onto the street.
- Lockdown. Securing your doors to keep a threat outside.
- Communication. Telling people quickly what's happening and what to do.
The law doesn't dictate exactly how you do any of this. It asks for what's "reasonably practicable," meaning proportionate to your venue, not a fixed technical standard, and never a requirement to buy equipment or overhaul your security setup. See the four procedures explained for the general version of each, and the standard tier explained for the full duty.
Few venues start closer to compliant than a nightclub. Killing the music and bringing the house lights up already works as a near-universal signal that something has changed, which covers most of your communication procedure before you've written a word. Door and floor staff already manage crowd flow and read a room for trouble, so writing a procedure is often just naming what they'd already do on instinct. The part worth thinking through specifically is egress: how long it actually takes a packed dancefloor to clear through the exits you have, not what your capacity certificate implies it should take.
What you do not have to do
A lot of the worry around Martyn's Law comes from assuming it means CCTV upgrades, an expensive consultant, or mandatory training courses for your team. None of that is required at the standard tier.
- You do not need a written plan by law, though the guidance recommends one, since it's hard to demonstrate compliance without it (para 7.32).
- You do not need additional CCTV beyond what you already run for other reasons.
- You do not need paid or accredited training. Using a third-party product or service is never mandatory to comply (para 6.7).
- You do not need to review your procedures on a set schedule. Reviewing periodically is good practice, not a legal requirement (para 7.29).
- You do not need a risk assessment document or a designated senior individual at the standard tier. Those apply only at the enhanced tier.
What all this costs, and an easier way to do it
None of the above costs money. Every duty above can be worked out and written down by hand, for free, and plenty of venues will do exactly that.
What takes real time is the part in between: turning what your door and floor staff already do on instinct into something written down clearly enough that a new starter could read it and know what to do. That's what Martyn's Law Plan is built for. It's a short online questionnaire about your venue, its layout, your capacity figures, and how your team already works, that turns your answers into your four procedures, a written plan, and a printable action card for each role, rather than a generic security-industry template.

Common questions
Is our licensed capacity the number that decides our tier?
It can be your evidence either way, but it isn't automatically the answer. A nightclub with a safe occupancy of 875 and a genuine historic peak of 725 sits in the standard tier, because what actually happens matters more than the theoretical maximum. A nightclub enforcing its full licensed capacity of 975 with a door clicker, and genuinely reaching it, sits in the enhanced tier, because that's its real, evidenced peak. Use whichever method actually reflects your venue's numbers.
Do ticketed club nights make us a qualifying event?
Only if a specific night meets all three tests: 800 or more expected, open to the public, and entry controlled through a secure ticketed or paid perimeter. Most regular club nights, even ticketed ones, don't clear 800 and are governed by your premises's own standing duties, not the separate events regime. See events and festivals if a specific promoted night looks genuinely different from your normal operation.
We already have security staff on the door. Are we compliant?
Door staff already do a lot of what these procedures need. Reading a room, managing flow, stepping in fast, that's a real head start, and they're often the people best placed to help write the procedures. But staffing and procedures aren't the same duty. What the Act asks for is evacuation, invacuation, lockdown and communication procedures your whole team knows and could follow, not just security numbers on the door.
