SIA Licence
The credit-card-sized badge issued by the Security Industry Authority that authorises an individual to carry out licensable conduct in the UK private security industry.
An SIA licence is the credit-card-sized badge issued by the Security Industry Authority under the Private Security Industry Act 2001. It authorises the holder to carry out licensable conduct in the UK private security industry. The SIA was established to raise standards in private security: every door supervisor at licensed premises, every security guard, every close protection officer, and every CCTV operator (where applicable) must hold a current SIA licence in the relevant category. Operating without a licence is a criminal offence. Knowingly using unlicensed personnel is a more serious offence.
Key Points
- An SIA licence authorises an individual to carry out licensable conduct in the UK private security industry.
- Door supervisors at licensed premises require the SIA Door Supervisor licence.

SIA licence categories
There are several SIA licence categories: Door Supervisor (front-line at licensed premises), Security Guard (general manned guarding), CCTV Operator (Public Space Surveillance), Close Protection (bodyguard work), Cash and Valuables in Transit, and Vehicle Immobiliser (Northern Ireland only). The Door Supervisor licence is what venue operators care about most. It authorises front-line work at licensed premises and is mandatory for door staff.
Verifying an SIA licence
The SIA provides a public register at services.sia.homeoffice.gov.uk/rlr where you can look up an individual's licence by badge number or by name and date of birth. Verify three things: the licence number matches the holder, the licence type is Door Supervisor (other categories such as Security Guard or CCTV Operator are not authorised for door work), and the expiry date is in the future. Record the verification with the date and the staff member who verified.
Validity, renewal, and ACS
An SIA licence is valid for three years. Renewal requires retaking the relevant qualification (or top-up training where eligible) and reapplying. The Approved Contractor Scheme (ACS) is a voluntary quality scheme run by the SIA for security businesses. ACS-approved companies meet a published standard covering management, training, and operational performance. Many local authorities expect or require venues to engage ACS-approved providers.
Frequently Asked Questions
How do I verify a door supervisor's SIA licence?
Use the SIA public register at services.sia.homeoffice.gov.uk/rlr to check the licence number against the holder's name and confirm the expiry date. Verify at the point of engagement and record the verification.
How long does it take to get an SIA licence?
Once an applicant has completed the qualification (typically a 4 to 5 day course for the Door Supervisor) and submitted their application with DBS check, the SIA aims to process applications within 6 weeks. Top-up renewals are usually faster.
Does an SIA licence need to be visible while on duty?
Yes. Section 9 of the Private Security Industry Act 2001 requires licensable conduct to be carried out by individuals displaying their licence in a manner readily visible. Door supervisors typically wear the badge on a lanyard or armband.
Can a venue use unlicensed staff for door work?
No. Carrying out licensable conduct without an SIA licence is a criminal offence carrying up to 6 months imprisonment. Knowingly using unlicensed personnel is a more serious offence carrying up to 5 years imprisonment. Even unknowing use can trigger a premises licence review.
