Your venue’s door is your first line of defence, and your first impression. The wrong person let in can put your customers, your staff, your premises, and your licence at risk in seconds. The right door supervision team does the opposite: it deters trouble before it starts, manages situations professionally when they arise, and creates a safe, welcoming environment that keeps your customers coming back.
Guard Mark Security provides professional door supervision services across the UK, with SIA-licensed and BS7858-vetted door supervisors available for licenced venues, nightclubs, bars, pubs, hotels, events, festivals, and private functions. All our door supervisors hold the full SIA Door Supervisor (DS) licence, a legal requirement for working at licensed premises that a standard security guard licence does not cover.
From Yorkshire and Manchester to London and the West Midlands, our experienced door supervision teams are deployed 24 hours a day, 7 days a week, 365 days a year.
