How to check an SIA licence

Last checked against GOV.UK on 8 October 2026. Fees and rules change, so confirm the details on GOV.UK before you apply.

If you employ security staff, or you want to check the person on your door, you can check an SIA licence for free using the official register. Employers have to do it, and it only takes a minute.

The short version: search the SIA register of licence holders with the 16-digit licence number, or with a surname and other personal details such as date of birth and security role.

How to check

  1. Go to the SIA register of licence holders.
  2. Search by the 16-digit licence number, or by surname and other personal details such as date of birth and security role.
  3. Check the name, licence sector and status match the person in front of you.

The register shows the licence sector, status and name. It does not show a home address.

Why employers must check

The SIA says companies must verify that anyone in a licensable role holds a valid licence, and the register is the simplest way to do that. If someone does not hold the right licence, make sure they get training and a licence before they work.
