How To Check A Security Guard's SIA Licence

Licensed officers are a legal requirement and a sign of a responsible supplier. Here is how to check, and what to ask.

How To Check A Security Guard's SIA Licence

By RMSS LTD · Updated 25 October 2026

In the UK, the Security Industry Authority licenses people who carry out certain security activities. Working in a licensable role without a licence is a criminal offence, and so is using someone who does not hold one. Checking is quick and it protects you.

Which Roles Need A Licence

Licensable activities include security guarding, door supervision, CCTV operation, close protection and key holding. Directors and managers of companies that supply licensable security staff under a contract also need a licence. The SIA explains who needs one on GOV.UK.

How To Check A Licence

  1. Ask the supplier for the name and licence number of each officer before the shift or event.
  2. Search the SIA's public register of licence holders on the SIA website to confirm the licence is valid, the dates, and the activity it covers.
  3. On the day, ask to see the officer's licence card. Check the photograph, the name, the expiry date and the activity.

What To Ask Your Supplier

  • How do you check licences, and how often?
  • Can I see the licence numbers of the people you are sending?
  • What happens if someone arrives without a valid licence?
  • Are you an SIA Approved Contractor, and for which activities?

What Happens If A Company Uses Unlicensed Staff

Using unlicensed staff in licensable roles can lead to prosecution, and directors have been convicted. For a venue or organiser it can also put insurance, licensing conditions and your reputation at risk. This is one reason that a supplier's systems for checking licences matter as much as its price. Our SIA Approved Contractor status means the SIA has assessed ours.

Event Stewards

Whether a steward needs a licence depends on the duties. People who only guide and help attendees usually do not. People who carry out licensable activities, such as controlling entry at a licensed venue, do. The SIA's events guidance explains where the line sits, and a good supplier will explain which of its staff are licensed for which role. For planning, see our event security planning checklist.
