Your SIA Door Supervisor Licence is valid for 3 years. Once it expires, you can simply take a refresher course and re-apply for it. 

Applicants will need to hold a Level 2 Award for 'Upskilling a Door Supervisor Working within the Private Security Industry'. This is a mandatory qualification for those seeking to renew their SIA Door Supervisors Licence.

SIA licences do not renew automatically, so you will need to renew your licence if you wish to continue working in the same role after your current licence expires.

Once you have attended he upskilling course, you can renew your SIA licence at the Official SIA Website.
