Safe Capacity
The maximum number of people who can safely occupy a venue, set by fire risk assessment and premises licence conditions.
Safe capacity is the maximum number of people who can safely occupy a venue. It is set by two overlapping frameworks. Fire safety law (the Regulatory Reform (Fire Safety) Order 2005) requires a fire risk assessment that includes maximum occupancy for safe evacuation. Licensing law (the Licensing Act 2003) sets capacity through premises licence conditions and the layout submitted with the application. Where the two figures differ, the lower one governs. For venues with multiple layouts (seated, standing, mixed), the safe capacity differs per layout, which makes per-layout occupancy logging important.
Key Points
- Safe capacity is the maximum number of people who can safely occupy a venue.
- Set by fire safety law (Fire Safety Order 2005) and licensing law (Licensing Act 2003).
- Where figures differ, the lower one governs.
- Per-layout capacity profiles are needed for venues that flex between configurations.
- Capacity logging at intervals through the night is increasingly a licence condition.
How capacity is calculated
For fire safety, capacity is calculated based on floor area, the available means of escape, and the time required to evacuate. The standard is that everyone must be able to leave to a place of safety within a defined time. A typical formula starts with the minimum exit width per person (often 5mm of exit width per person for level escape) and applies it across all available exits, then cross-checks against floor area at expected occupancy density. For licensed premises, the layout plans submitted with the licence application typically set out capacity by area; the licensing authority may set conditions that align or diverge from the fire risk assessment.
Per-layout capacity profiles
Many venues operate multiple layouts. A 600-capacity seated venue may permit 800 standing. A nightclub may have a "main floor" capacity and a "main floor plus mezzanine" capacity. Each layout has different exit widths effective, different fire load, and different evacuation times. Operators should document a capacity profile for each layout, activate the right one per session, and log occupancy against the active profile.
Why capacity records matter
Capacity is one of the most cited issues at licensing review and the most likely to come up in fire safety inspections. Records that show occupancy stayed within capacity through the night - and that the venue closed entry when approaching capacity - are strong evidence of responsible operation. Records that show occupancy was never measured at all are concerning. Many premises licences now explicitly require capacity logging at intervals.
Frequently Asked Questions
How is venue capacity calculated?
Through the fire risk assessment using floor area, exit widths, and evacuation time. The Regulatory Reform (Fire Safety) Order 2005 makes the responsible person accountable for the assessment. Licensed premises additionally have capacity set or implied by the licence layout plans.
What's the difference between safe capacity and licensed capacity?
Safe capacity is the fire safety figure (how many can evacuate safely). Licensed capacity is the figure set or implied by the premises licence (how many the venue is authorised to admit). Where the two differ, the lower figure governs operationally.
Can I have different capacities for different layouts?
Yes. Many venues operate seated, standing, and mixed layouts with different capacities. Each layout should have a documented capacity profile, and capacity logs should be tied to the active profile.
What happens if I exceed capacity?
Exceeding capacity is a breach of the premises licence and the fire risk assessment. Consequences range from informal action (police asking the venue to clear excess) through to fire safety enforcement notices, prosecution, and licensing review. In serious cases the venue can be closed under fire safety provisions.
