The Security Industry Authority (SIA) regulates the private security industry in the United Kingdom, and compliance with its requirements is non-negotiable for any security company operating here. Yet many firms — particularly those growing quickly — find themselves managing SIA compliance through spreadsheets, email reminders, and a fair amount of hope.
In 2026, that approach carries more risk than ever.
What the SIA Requires
The SIA’s mandate covers licensing, standards, and enforcement across the UK private security sector. For security companies, the key obligations fall into several areas:
Licence Compliance for Individual Guards
Every frontline security operative must hold a valid SIA licence appropriate to their role. The main licence types are:
- Door Supervisor — required for anyone working at licensed premises
- Security Guard — required for guarding duties across commercial and public sites
- CCTV (Public Space Surveillance) — required for operators in public areas
- Close Protection — required for personal protection roles
- Vehicle Immobiliser — required for wheel clamping operations
Deploying a guard in a role that requires a licence they don’t hold is a criminal offence. The licence must be valid — an expired licence is treated the same as no licence.
2026 Changes: What’s New This Year
Several changes have come into effect in 2026 that security companies should be aware of:
Increased licence fees: From 1 April 2026, the SIA licence fee increased to £204 per application. This doesn’t affect currently-valid licences but should be factored into workforce cost planning, particularly for companies with high staff turnover.
Refresher training requirements: The SIA has introduced mandatory refresher qualifications for licence renewals, including stricter first aid prerequisites and expanded requirements for counter-terrorism and vulnerability awareness training.
Close protection changes: From 1 April 2026, a Level 3 First Aid at Work qualification became a prerequisite for close protection licence renewals, alongside mandatory refresher training.
Overseas criminal history scrutiny: The SIA is applying closer scrutiny to applicants who have spent six months or more abroad in the previous ten years, who may now be required to provide overseas police certificates.
Martyn’s Law: The Terrorism (Protection of Premises) Act — commonly called Martyn’s Law — introduces security requirements for public venues and events. Security companies operating in these environments should understand how the legislation affects their deployment requirements and documentation obligations.
Practical Compliance Challenges
Understanding the requirements is the easy part. The challenge is maintaining compliance across a workforce that’s constantly changing — guards join and leave, licences expire, and roles shift.
The Expiry Date Problem
A guard’s SIA licence is valid for three years. If you employ 100 guards, you have approximately 33 renewals per year — roughly one every 11 days. Each renewal requires the guard to complete refresher training, submit an application, pass a DBS check, and wait 6–8 weeks for processing.
If you’re tracking expiry dates in a spreadsheet, you’re relying on someone to check it consistently and flag renewals far enough in advance for the guard to complete the process before their current licence expires.
Many companies don’t have a robust process for this — and the first they know about a problem is when a guard turns up for a shift with an expired licence.
The Verification Gap
When a guard is assigned to a site, can you confirm in real time that their licence is valid for the role they’re being deployed in? If a supervisor is approving deployments manually, they’re likely checking a spreadsheet that may be days or weeks out of date.
The SIA publishes a public register of all active licence holders. Platforms that connect directly to this register can verify licence status in real time — rather than relying on records maintained internally.
How Technology Closes the Gap
Purpose-built security workforce management platforms address compliance in two ways: automation and verification.
Automated expiry monitoring: Rather than relying on someone to check a spreadsheet, a well-designed system monitors licence expiry dates continuously and generates alerts when renewal windows open. The goal is to have renewals underway before the current licence expires — not scrambling afterwards.
SIA Public Register integration: Platforms that connect directly to the SIA register can verify in real time whether a guard’s licence is valid, current, and appropriate for their role — rather than relying on internal records. TacDesk’s SIA Public Register auto-sync flags expired and expiring licences automatically, without anyone needing to manually check.
Deployment controls: Before a guard is assigned to a shift, the system can check their current licence status and block the deployment if their licence has expired or isn’t valid for the required role.
Building a Compliance Culture
Technology is one part of the answer. The other is operational culture. Security companies that stay consistently compliant tend to share a few common practices:
- Licence expiry dates are tracked with 90-day, 60-day, and 30-day renewal reminders
- Guards are briefed on their responsibility to initiate renewal promptly
- Supervisors have a clear escalation path when a guard’s licence is approaching expiry
- Compliance checks are part of the pre-deployment workflow, not an afterthought
SIA compliance is not a one-off task — it’s an ongoing operational commitment. The companies that handle it well are the ones who’ve built it into their processes rather than treating it as someone’s side responsibility.
