Your security guards are your most visible asset — but their SIA licences are the invisible foundation that keeps your operation legal. A single expired licence on a live deployment isn’t just a compliance risk; it exposes your company to prosecution under the Private Security Industry Act 2001 and could void your public liability insurance at exactly the wrong moment.
The problem isn’t that security managers don’t know licences expire. The problem is scale. A company running 50 guards has 50 expiry dates to track. A company running 250 guards has 250. And the SIA doesn’t send renewal reminders to employers — only to the individual licence holder.
When Do SIA Licences Expire?
SIA licences are valid for three years from the date of issue. The licence holder receives a reminder from the SIA approximately 16 weeks before expiry, giving them time to complete their licence renewal application and any required refresher training.
However, this reminder goes to the guard — not to you. If your guard doesn’t act on it, or simply doesn’t tell you they’ve let their licence lapse, you may not find out until a client flags it during an audit or a doorstep inspection catches you out.
The consequences are serious:
- Deploying an unlicensed guard is a criminal offence under Section 5 of the Private Security Industry Act 2001, carrying an unlimited fine or up to five years’ imprisonment for the employer.
- The SIA can revoke your Approved Contractor Scheme (ACS) status if systemic compliance failures are found.
- Your public liability insurance policy may be invalidated for incidents involving unlicensed personnel.
- Clients who discover unlicensed guards on their sites are likely to terminate your contract with immediate effect.
The SIA Public Register: Your Most Important Tool
The SIA Public Register is a free, publicly accessible database of all current SIA licence holders in the UK. It shows the licence number, activity type (Door Supervisor, Security Guard, CCTV Operator, etc.), and whether the licence is currently valid.
This is the definitive source of truth for licence status. Your own internal records — spreadsheets, HR systems, copies of licence cards — are only as accurate as the last time someone updated them. The SIA Public Register reflects current status in real time.
Best practice is to verify every guard’s licence against the Public Register before their first deployment and then again at regular intervals. Quarterly checks are a common standard, but monthly checks are increasingly the expectation for ACS-accredited companies operating in higher-risk environments.
Common Pitfalls in Licence Expiry Management
Relying on guards to self-report
Some guards genuinely forget to renew, particularly if they’ve been in the industry a long time and have only renewed once or twice before. Others may know their licence has lapsed and hope no one notices. Neither scenario ends well for you. Self-reporting is a useful secondary check, not a primary compliance mechanism.
Spreadsheet staleness
Tracking expiry dates in a spreadsheet is better than not tracking them at all, but spreadsheets don’t update themselves. They go stale. The person who maintained them leaves. Someone edits the wrong row. The spreadsheet that was accurate in January is quietly wrong by April, and you don’t find out until you’re standing in front of a client explaining why you deployed an unlicensed officer.
Treating the licence card as proof
An SIA licence card can be stolen, forged, or retained after the licence has been revoked. The card itself is not proof of current licence validity — the SIA Public Register is. Always cross-reference the card against the register.
Missing the renewal window
The SIA processes licence renewals within 25 working days, but processing times can vary. Renewals submitted late or returned with errors can leave guards in a period where their licence has technically expired and the new one hasn’t yet arrived. Best practice is to start the renewal conversation with your guards at least 12 weeks before expiry — not 16.
Building a Robust Licence Expiry Process
A reliable SIA licence expiry management process has three components:
1. A centralised, real-time register
Every guard in your workforce should have their licence number, expiry date, and licence activity type recorded in a single, authoritative system. This system needs to be accessible to anyone who approves deployments and updated whenever a guard’s licence status changes.
2. Automated expiry alerts
You should receive an alert — not a note in a spreadsheet you might not open — when a guard’s licence is approaching expiry. Alerts at 90 days, 60 days, and 30 days give you time to prompt the guard, chase renewal progress, and manage cover if there’s a delay. Alerts at 7 days or less are emergency warnings, not action triggers.
3. Pre-deployment checks against the Public Register
Before any guard is deployed to a new assignment, their licence status should be verified against the SIA Public Register — not just your internal records. Some companies run nightly checks against the register for their entire active workforce so any revocation (which can happen mid-licence due to criminal conviction) is caught immediately.
How Technology Changes the Picture
Manual Public Register checks are time-consuming at scale. A manager responsible for 100 guards cannot realistically log on to the SIA website and check 100 entries every morning. This is where purpose-built guard management software changes the equation.
Platforms that integrate directly with the SIA Public Register — running automatic, scheduled checks against your workforce and surfacing expired or soon-to-expire licences in your dashboard — remove the manual burden and eliminate the risk of a stale spreadsheet. Guards with licences expiring in the next 30, 60, or 90 days appear in a compliance view; guards whose licences have already lapsed are flagged before they can be scheduled for a shift.
This is the standard that ACS-accredited companies are increasingly expected to meet, and it’s the standard that protects your business when a client asks to see your compliance records.
The Cost of Getting It Wrong
In 2024, the SIA prosecuted a number of security companies for deploying unlicensed operatives — not rogue firms operating outside the law, but established companies that had simply lost track of who was licensed and who wasn’t. The fines and reputational damage were significant. The common thread was an over-reliance on manual processes that couldn’t scale.
SIA licence expiry management is not a complex problem. It is a volume problem. The solution is a system that scales with your workforce — not a spreadsheet that breaks at 50 rows.
TacDesk automatically checks your guards’ SIA licences against the Public Register and flags any that are expired or approaching expiry — so your compliance view is always current, without the manual overhead. Find out more about how TacDesk supports SIA licence compliance.
