With 50 guards on your books, an average of one to two SIA licences expire every single month. Miss just one, and the consequences go far beyond an admin headache: working with an expired licence is a criminal offence, and deploying an unlicensed guard is a separate offence for the company — carrying up to five years’ imprisonment on indictment.
This guide gives you a practical SIA licence expiry tracking system built for UK security companies: the renewal timelines that matter, what a missed expiry actually costs, and a five-step process that makes it structurally impossible for an expired guard to end up on a shift.
Key Takeaways
- Every SIA licence lasts 3 years — with 50 guards, expect ~1.4 expiries per month; with 200 guards, ~5.6 per month.
- Renewals can be submitted up to 4 months early with no time lost; SIA processing takes 10–20 working days.
- A guard working on an expired licence faces up to 6 months’ imprisonment and a £5,000 fine; a company deploying one faces up to 5 years’ imprisonment.
- Your legal defence is proving you “took all reasonable steps” — a documented, automated tracking system is that defence.
- Spreadsheets fail at scale. The reliable setup is: central register + tiered alerts + renewal workflow + scheduling block + audit trail.
Why One Missed Expiry Is a Business-Threatening Event
Most compliance failures cost money. A missed SIA licence expiry can cost the business itself. Here’s what rides on every expiry date in your workforce:
- Criminal liability for the guard. Engaging in licensable conduct without a licence is an offence punishable by up to 6 months’ imprisonment, a fine of up to £5,000, or both.
- Criminal liability for the company. Under section 5 of the Private Security Industry Act 2001, supplying security services through an unlicensed operative is a separate offence — up to 6 months’ imprisonment or an unlimited fine on summary conviction, and up to 5 years’ imprisonment on indictment.
- Insurance exposure. Many public liability and professional indemnity policies exclude claims arising from unlicensed activity. One incident involving an expired guard can mean an uninsured loss.
- Client contract breach. Corporate and public-sector contracts require SIA-licensed deployment as a condition. A discovered breach can trigger termination clauses and damage claims.
- ACS accreditation at risk. The SIA Approved Contractor Scheme demands demonstrable workforce licensing control. A pattern of expiries is exactly what audits are designed to find.

There is one crucial detail in the legislation worth knowing: it is a defence to show that you “took all reasonable steps” to ensure no unlicensed operative was deployed. A spreadsheet nobody checks is not all reasonable steps. A documented, automated tracking system with an audit trail is. Your tracking system isn’t just admin — it’s your legal defence.
The Maths of the Problem: Why 50+ Guards Breaks Manual Tracking
SIA licences last 3 years (36 months). Divide your headcount by 36 and you get your average monthly expiry load:
| Guards on your books | Average expiries per month | Average expiries per year |
| 25 | ~0.7 | ~8 |
| 50 | ~1.4 | ~17 |
| 100 | ~2.8 | ~33 |
| 200 | ~5.6 | ~67 |
| 500 | ~13.9 | ~167 |
And each expiry isn’t a single task — it’s a chain. Renewal applications can be submitted up to 4 months before expiry, the SIA recommends applying at least 6 weeks ahead, and processing typically takes 10–20 working days. Guards who qualified before April 2021 usually need Top-Up training plus a valid Emergency First Aid at Work certificate first. So every expiry is really a 4-month mini-project with a hard legal deadline.
Now add the realities of a 50+ guard operation: relief staff, subcontractors, guards who joined with licences issued at different times, staff turnover, and shift patterns that change weekly. A spreadsheet maintained by one ops manager becomes a single point of failure the moment that person is on leave, busy, or leaves the company.
The 5-Step SIA Licence Tracking System
Step 1: Build a central licence register
Every guard — employed, relief, and subcontracted — gets a single record capturing: full name, SIA licence number, licence sector (Security Guarding, Door Supervision, CCTV, Close Protection), issue date, expiry date, and a scan or photo of the licence card. Capture this at onboarding before the guard’s first shift, and verify it against the SIA register of licence holders. No record, no shifts.
Step 2: Set tiered expiry alerts
A single reminder is not a system. Use escalating alerts so a missed notification never becomes a missed expiry:
| When | Action | Owner |
| 120 days before | Guard notified: renewal window now open; book Top-Up/EFAW if needed | Guard + Ops |
| 90 days before | Training booked; renewal application started | Guard + Ops |
| 60 days before | Confirm application submitted to SIA | Ops |
| 30 days before | Escalation: chase SIA processing; arrange cover shifts if at risk | Ops Manager |
| 7 days before | Final check: new licence received or guard stood down from rota | Ops Manager |
Step 3: Run a documented renewal workflow
Each alert needs a named owner and a recorded outcome. The workflow for every renewal: confirm training requirements → guard completes Top-Up/EFAW → application submitted → SIA processing tracked → new licence verified and filed. Record each step with a date. This record is what you show an SIA auditor — or a court — to prove all reasonable steps were taken.
Step 4: Hard-block expired guards from scheduling
Alerts prevent most failures; a scheduling block catches the rest. Your scheduling process must refuse to assign shifts to any guard whose licence is expired or unverified. This is the single most effective control you can implement — it converts a human-memory problem into a system rule. BOOK ON enforces this automatically: only approved, SIA-licensed, verified guards can be assigned to shifts, with real-time facial recognition and geofenced clock-in confirming the right person attends.
Step 5: Keep an audit-ready trail
For every guard, maintain a compliance P-file: licence copies, renewal applications, training certificates, vetting records, and the alert/workflow history. When the SIA inspects or a client asks for assurance, you produce the file — not a scramble through emails. Digital compliance files that update continuously turn audit preparation from a crisis into a non-event.
SIA Licence Renewal: Timeline and Costs
Renewal timeline
| Timeframe | What to do |
| 4 months before expiry | Earliest renewal window opens — new 3-year term starts the day after current expiry, so nothing is lost by applying early |
| 6–8 weeks before | Ideal application point; SIA’s recommended minimum lead time |
| 2–4 weeks before | Latest safe window — processing takes 10–20 working days and delays happen |
| Expiry day | Guard must stop all licensable work immediately if the new licence hasn’t been granted — no grace period |
Renewal costs (2026)
| Item | Cost | Notes |
| SIA licence fee | £204 | Valid 3 years; fee rose from April 2026 |
| Door Supervisor / Security Guard Top-Up | £70–£150 | Required for those who qualified before April 2021 |
| Emergency First Aid at Work (EFAW) | £60–£120 | Must be valid before Top-Up and renewal |
Budget roughly £330–£475 per guard per renewal cycle including training — and remember that a guard stood down for a lapsed licence costs you far more in cover shifts and lost contract confidence.
What to Do When a Licence Has Already Expired
If you discover an expired licence in your workforce, act immediately:
- Stand the guard down from all licensable duties today. There is no grace period — not one shift, not one hour.
- Check how long it has been expired. If less than 3 years, the guard can usually re-apply after completing refresher training (1–2 days). If more than 3 years, they must retake the full training course from scratch.
- Review your audit trail. Document what happened, why the alert chain failed, and what you changed. Regulators and clients judge you on the response as much as the failure.
- Verify before re-deploying. The guard returns to the rota only after the new licence is granted and verified — never on the promise that an application is “in progress.”
How Automation Makes Missed Expiries Structurally Impossible
The five-step system above works on paper — but at 50+ guards, running it by hand is itself the risk. This is where purpose-built security guard management software changes the equation:
- Automated daily SIA licence checks on every guard, with instant alerts on expiries and revocations — no manual register lookups.
- Expiry alerts before it’s too late, escalated to the right people at the right time.
- Scheduling that refuses unverified guards, so an expired licence can never silently end up on a rota.
- BS7858 vetting records and training certificates stored against each guard’s digital compliance P-file.
- Full BOOK ON Accounts access — invoicing, payroll, and margin tracking alongside compliance — on the Advanced Management plan.
The result: licence tracking stops depending on one person’s memory and becomes a property of the system. That’s what “all reasonable steps” looks like in practice.
Conclusion
SIA licence expiry tracking at 50+ guards isn’t an admin task — it’s a legal control. The maths guarantees monthly expiries, the law guarantees severe consequences for missing one, and the only reliable defence is a documented system: central register, tiered alerts, a renewal workflow with named owners, a scheduling block, and an audit-ready trail.
Build the system once, and expiries stop being emergencies. Leave it to memory and spreadsheets, and it’s not a question of if you’ll miss one — it’s when.
