Capacity Management Requirements for UK Venues

Exceeding your venue's capacity is one of the fastest ways to lose your premises licence. It is also dangerous. Every major crowd crush incident in UK history has involved a venue or space that exceeded its safe capacity.

Capacity management is not just about counting heads. It is a legal obligation with specific requirements around how you determine, monitor, and enforce your limits.

How venue capacity is determined

Your venue's maximum capacity is set by one or more of these factors:

Fire risk assessment

Your fire risk assessment must calculate the maximum number of occupants based on available escape routes. The calculation considers:

• Width of escape routes - measured at the narrowest point
• Number of exits - assuming the largest single exit is unavailable
• Travel distance - the maximum distance anyone needs to cover to reach an exit
• Floor area - usable space excluding fixed furniture, bars, stages, and equipment

This calculation assumes at least one exit is out of action. If your venue has three exits, the capacity is based on the remaining two being able to handle full evacuation.

Premises licence conditions

Your premises licence may specify a maximum capacity figure. This is typically set by the licensing authority based on fire safety calculations and may also account for:

• Noise and public nuisance considerations
• The character of the surrounding area
• Police and environmental health recommendations

The capacity on your premises licence is legally binding. Exceeding it is a breach of your licence conditions.

Building regulations

The original building design will have incorporated capacity assumptions into structural engineering, ventilation, and sanitary provision. These may differ from your fire-calculated capacity and premises licence figure. The lowest figure applies.

Your legal obligations

Know your number

It sounds obvious, but many venues cannot immediately state their maximum permitted capacity. Every member of management staff should know:

• The maximum permitted capacity for the entire premises
• The capacity for each floor or distinct area if your licence specifies this
• Whether the capacity figure includes or excludes staff

Monitor in real time

You need a system for knowing how many people are in your venue at any given time. Acceptable methods include:

• Clicker counts at each entrance and exit
• Electronic counting systems (turnstiles, beam counters, camera-based systems)
• Ticket-based events where total ticket sales plus guest list equals maximum capacity

Whatever system you use, it must be reliable and auditable. "We roughly estimate" is not a system.

Enforce your limit

When your venue approaches capacity, you must have procedures in place:

• Stop admissions - door staff must be empowered to stop the queue, regardless of commercial pressure
• One-in-one-out - a manageable approach for venues near capacity
• Monitor re-entry - people leaving for a cigarette still count towards your total
• VIP and guest list - these do not exempt people from the capacity count

Record and evidence

You should be able to demonstrate your capacity management to any inspector. This means:

• Attendance records - ideally timestamped records showing occupancy throughout the night
• Peak occupancy - the highest number reached during each trading session
• Actions taken - any time admissions were stopped or limited, and when

Common compliance failures

No counting system

The most basic failure. If you have no method of tracking occupancy, you have no way of knowing whether you are exceeding capacity. Licensing authorities will treat this as a serious concern.

Counting entrances but not exits

If you only count people coming in but not going out, your count drifts upward all night and becomes meaningless. You need counting at every point where people enter or leave.

Ignoring staff and performers

Your capacity figure may or may not include staff, depending on how it was calculated and what your premises licence states. Check the specific wording. If it says "maximum occupancy of 350 persons" without qualification, that includes everyone - staff, performers, security.

Commercial pressure overriding safety

The busiest night of the year is also the night you are most likely to exceed capacity. Managers and door staff need explicit authority - backed by the licence holder - to stop admissions regardless of the queue size, the importance of the event, or the revenue implications.

Build a culture where stopping the queue is a professional decision, not a failure.

Different areas with different limits

If your premises licence specifies capacity limits for individual areas (ground floor, first floor, garden), you need to track each separately. Total venue capacity of 400 does not mean you can put 400 people on the ground floor if that area has a limit of 250.

Capacity and Martyn's Law

The Terrorism (Protection of Premises) Act 2023 (Martyn's Law) uses capacity thresholds to determine your obligations:

• 200-799 capacity - standard tier requirements
• 800+ capacity - enhanced tier requirements

Your capacity figure directly determines which tier of counter-terrorism obligations apply to your venue. Accurate capacity management is therefore linked to your Martyn's Law compliance.

Methods for counting

Manual clicker counts

The simplest method. Door supervisors use mechanical or digital clickers at each entry and exit point.

Pros: Low cost, no technology dependency, easy to implement Cons: Human error, requires discipline, difficult to audit retrospectively

Electronic counting systems

Beam counters, turnstiles, or camera-based systems that count automatically.

Pros: More accurate, auditable data, real-time dashboards Cons: Higher cost, technology failures, requires calibration and maintenance

Ticket and wristband systems

For ticketed events, capacity is controlled at the point of sale.

Pros: Precise control, advance visibility of numbers, no counting needed at the door Cons: Does not account for no-shows or early leavers, requires a ticketed model

Digital attendance tracking

Purpose-built venue management systems that combine door counts with timestamped records.

Pros: Real-time tracking, historical data, audit-ready reports, alerts at threshold Cons: Requires investment and staff training

The best approach for most venues is a combination: electronic or digital counting as the primary system, with manual counts as verification and backup.

What to do when you reach capacity

1. Notify door staff - clear communication that the venue is at capacity
2. Stop admissions - no exceptions. VIPs, guest list, and "just one more" all count
3. Implement one-in-one-out if appropriate for the event
4. Inform waiting patrons - manage expectations to reduce frustration and potential disorder
5. Monitor exits - track people leaving so admissions can resume when safe
6. Log the event - record the time capacity was reached, when admissions stopped, and when they resumed
