What can door supervisors for licensed venues legally do?

Spring is here, bank holiday parties and busy nights are coming. For operators, the difference between a smooth evening and a licensing headache often sits at the door. This blog sets out what SIA-licensed door supervisors can legally do in the UK, where the limits are, and how to brief and staff effectively for pubs, bars, clubs and mixed-use spaces.

Legal duties and limits for SIA door supervisors

SIA-licensed door supervisors are private security operatives regulated by the Security Industry Authority. They must display their licence while working and follow the law, venue policies and licence conditions. Their key powers and limits include:

• Entry control and refusal: They can control queues and refuse entry based on house rules, dress code, capacity, intoxication, previously issued bans or safeguarding concerns. Refusals must be lawful and non-discriminatory under the Equality Act 2010 and local licence conditions.
• Age and ID checks: They can request proof of age and check ID. If an ID is inadequate or suspected to be false, they can refuse entry. They cannot however forcibly seize ID, but they may retain suspected fake ID to pass to police where local protocols allow.
• Searches with consent: They may request a bag or person search as a condition of entry. Consent must be freely given; anyone can refuse, but refusal can mean no entry. Searches must be proportionate, same-sex where a pat-down is required, and conducted respectfully in a well-lit, CCTV-covered area with a witness where possible. Intimate searches are not permitted.
• Seizure of prohibited items: With consent or via a condition of entry, they can remove items banned by the venue such as glass, drugs, vape canisters or weapons. Illegal items should be secured and handed to police following the venue’s seizure and evidence procedures.
• Use of reasonable force: They may use reasonable, necessary and proportionate force to prevent crime, protect people, eject for legitimate reasons or defend themselves or others. Force must stop once the threat ends.
• Safeguarding and first aid: Supervisors must escalate welfare concerns, manage vulnerable persons, support spiking protocols, and deliver first aid within their training. They should promptly call emergency services where required and preserve scenes for investigation.
• Ejection and refusal re-entry: They can eject patrons who breach conditions, are violent, cause nuisance or present a safeguarding risk. Ejections should be coordinated, documented, and where practicable, witnessed on CCTV.

Ejections & Documentation

When ejecting someone, staff should explain the reason, seek voluntary compliance, involve at least two staff where possible, and only use force if necessary. Individuals should be guided to a safe area, with welfare support considered.

Serious incidents (e.g. assault or spiking) require evidence preservation and police involvement. Documentation is critical and should include:

• Incident logs (details, actions, witnesses)
• Seizure records (items and chain of custody)
• Refusal registers (reasons and evidence)
• Staff statements for serious incidents

De-escelation & risk management

Most issues arise at queues, entry points and bars. Effective de-escalation includes clear communication, calm behaviour, offering choices, separating conflicts and maintaining visible organisation (e.g. signage, lighting, queue systems).

Good coordination between door and bar staff prevents confusion. Strong de-escalation reduces conflict, improves safety and provides evidence of proportionate risk management.

Staffing Guidelines

Staffing depends on the venue size and risk level:

• Up to 150 capacity: 2 staff (plus floater if needed)
• 150–300: 3–4 staff
• 300–600: 5–8 staff
• 600+: approx. 1 per 75–100 patrons
