SIA Licence Requirements for Self-Employed and Small Companies (2025)

Whether you’re working solo as a security contractor or running a small security business, SIA licensing still applies. The same legal standards that apply to large firms also apply to individuals and small operations.

Here’s what you need to know to stay compliant.

🔐 Who Needs an SIA Licence?

If you carry out any licensable security work in the UK, you must hold an active SIA licence.

That includes:

  • Door Supervisors
  • Security Guards
  • CCTV (Public Space Surveillance) Operators
  • Close Protection Officers
  • Key Holders

Even if you’re self-employed or subcontracted, you’re responsible for your own licence. Agencies can’t cover you under theirs.

🧾 Types of SIA Licences

There are two main types:

1. Front Line Licence – Needed for anyone who directly performs security duties — e.g. working events, patrolling, or monitoring CCTV.

2. Non-Front Line Licence – For those who manage, supervise, or employ security staff but don’t personally carry out licensable activity.

Small company owners who employ others will often need both.

🧰 Licence Requirements for Self-Employed Workers

To get an SIA licence, you’ll need:

  • Valid first aid qualification (usually an Emergency First Aid at Work or equivalent)
  • SIA-recognised training course for your role
  • Proof of identity and right to work in the UK
  • Clean criminal record (or acceptable under SIA’s criminality criteria)

Your licence is personal — it’s tied to you, not your company.

🧾 Licence Requirements for Small Security Companies

If you employ or subcontract other security staff, you may also need:

  • Non-front line licence (if you manage others performing licensable work)
  • Approved Contractor Scheme (ACS) certification (optional but helps win business)
  • Proper insurance cover, including public liability and employer’s liability
  • Right-to-work checks and record-keeping for your team

🕒 Licence Renewal and Maintenance

SIA licences last three years and must be renewed before expiry.

Keep these in check:

  • Update your details if you move or change your name
  • Re-take first aid if it expires before your licence
  • Ensure all your staff have valid, active licences

Failure to renew or employing unlicensed staff can lead to heavy fines or prosecution.

💬 Final Thoughts

Being self-employed or running a small security business doesn’t exempt you from SIA licensing rules.

In fact, it makes compliance even more important — you’re responsible for your own legal footing and anyone you hire.

Keep your licence current, stay insured, and make sure your training and documentation are always up to date.
