Bar security in London works best when your bartenders never have to leave the bar. Sparta Guard supplies SIA-licensed, DBS-checked door supervisors who handle entry, ID checks and difficult customers, so your team can keep serving. Across Central London, bar door staff are usually on site within the hour, for tonight, a launch or every weekend, with no contract.
When bar staff handle security, service slows and small problems grow. A clear split looks like this:
| Situation | Your bar team | Your door supervisor |
|---|---|---|
| Someone looks under age | Asks for ID at the bar if unsure | Checks ID at the door, before they get in |
| A customer has had too much | Refuses the next drink | Backs up the refusal and asks them to leave if needed |
| Queue outside | Keeps serving | Manages the line, dress code and capacity |
| An argument at a table | Signals the door | Steps in, calms it down, removes people if necessary |
| Closing time | Last orders and cash-up | Clears the room and the pavement |
Door supervisors have the same legal powers as any member of the public.
Cocktail bars. Guests expect a host, not a heavy. Door staff in dark suits greet bookings, hold walk-ins politely when you are full and deal with problems out of sight.
Rooftop bars. Capacity is often limited by lifts or a single staircase. Door staff count people in and out and keep the stairs clear.
Basement and late-licence bars. A single entrance and a later crowd mean a tighter door, with more ID checks and more refusals.
Bottomless brunch and daytime sessions. Fast drinking in a two-hour slot can leave groups drunk by mid-afternoon. A door supervisor keeps the handover to the evening crowd calm.
Most bars run a Challenge 21 or Challenge 25 policy, and your premises licence may say which. Door staff check ID at the entrance, so your bartenders rarely have to. Commonly accepted forms are a passport, a photocard driving licence or a card with the PASS hologram. A good door supervisor spots borrowed or altered ID and refuses entry without a scene in the queue.
A busy bar can hide someone in trouble: a customer separated from friends, or someone who suddenly seems far more drunk than they should be. If your bar runs a scheme such as Ask for Angela, include it in the briefing. Door staff can keep a vulnerable person safe, call a friend or taxi, and contact 999 if needed.

Address, hours, capacity, number of door supervisors, dress code and your ID policy.
Local SIA-licensed door supervisors get the job straight away.
Walk them through entrances, the smoking area and how your team will call them.
The regular door supervisor cancels at 7pm on a Friday. A suited replacement is on the door before the late bookings arrive.
On the first warm weekend of the year, two door staff run the lift lobby and count capacity.
A late-licence launch night needs strict ID checks. Two door supervisors cover the door from 9pm.
Prices depend on the day, the hours, the number of door supervisors and the notice you give. Bars with regular weekend cover can ask about membership plans.

Not necessarily. Check your premises licence conditions, which may require door supervisors on certain nights or after a set time. Beyond that, many bars book door staff only when risk rises, such as weekends, late licences, launches or big sporting events.
Yes. Checking ID at the entrance is a normal part of door supervision. Door staff follow your Challenge 21 or Challenge 25 policy and refuse entry when a customer cannot prove their age with acceptable ID. This keeps under-age customers away from the bar.
Tell us your dress code when you book. Many bars prefer a dark suit or smart black clothing that fits the venue, while busier late-night bars may want a clearly identifiable security look. SIA door supervisors must display their licence while working.
Yes. Door supervisors can cover daytime sessions, brunches, launches and private hire, not only late nights. Tell us the start and finish times, expected numbers and whether the session runs straight into your evening trade, and we will cover the whole window.
They ask the customer to leave first and explain why, calmly and away from other guests where possible. Force is a last resort and must be reasonable. If a crime has taken place or someone is at risk, they call the police, and the incident goes in your log.
