Hiring security staff should reduce operational risk, not create more of it. However, when a business uses non-SIA licensed security guards, it can face legal action, insurance problems, contract issues, and serious reputational damage.
In the UK, most frontline private security roles require a valid SIA licence. Therefore, businesses cannot rely on verbal promises, photocopied badges, or last-minute staffing arrangements without proper checks. GOV.UK clearly advises employers to check that private security staff have the correct licence before hiring them.
This guide explains what can happen if your business uses unlicensed security guards, how SIA compliance works, and how to choose a properly licensed security provider.
What Does an SIA Licence Mean?
The Security Industry Authority, known as the SIA, regulates the UK private security industry. Its licensing system helps confirm that security operatives meet legal and professional requirements before they carry out licensable work.
An SIA licence usually confirms that the person has completed the required training, passed identity checks, met right-to-work requirements, and gone through relevant background screening.
The SIA licence also needs to match the role. For example, a door supervisor licence does not cover every possible security activity, and a CCTV operator may need a specific public space surveillance licence.
Common roles that may require an SIA licence include:
- Security guards
- Door supervisors
- CCTV operators
- Close protection officers
- Mobile patrol officers
- Key holding operatives
- Event security staff
As a result, businesses should always check the licence type, expiry date, and licence status before placing anyone on site.
Why Non-SIA Licensed Security Guards Create Serious Risk
Some businesses use unlicensed guards because they want to fill shifts quickly or reduce costs. However, this shortcut can create much larger problems later.
The SIA lists “engaging in licensable conduct without a licence” and “employing unlicensed persons in licensable conduct” as criminal offences under the Private Security Industry Act 2001.
That means the issue does not only affect the guard. In many cases, the business, contractor, manager, or director may also face scrutiny if unlicensed staff work on a site.
Legal Consequences for Businesses
Using non-SIA licensed security guards can expose a company to enforcement action, prosecution, and financial penalties.
Under the Private Security Industry Act 2001, working in licensable conduct without a licence is an offence. The legislation also covers the offence of using unlicensed security operatives.
Potential consequences may include:
- Criminal investigation
- Prosecution
- Court proceedings
- Fines
- Management scrutiny
- Loss of contracts
- Supplier compliance failure
Additionally, “I did not know” rarely works as a strong defence in a commercial setting. If your business hires or allows security personnel on site, you should have a clear process for checking compliance.
Insurance Problems After an Incident
Insurance is one of the biggest hidden risks of using unlicensed security guards.
Many businesses only discover the issue after something has gone wrong. For example, a theft, assault, injury, access control failure, or property damage incident may trigger an insurance claim. At that point, insurers may review whether the security staff were properly licensed and whether the provider followed legal requirements.
If the guards were not correctly licensed, the insurer may challenge the claim. Consequently, your business could face direct financial exposure.
This can affect:
- Public liability claims
- Employers’ liability issues
- Property damage claims
- Theft-related claims
- Contractual claims from clients
- Legal defence costs
For this reason, SIA licence compliance should form part of your risk management process before any guard starts work.
Reputational Damage and Lost Contracts
Legal and insurance risks matter, but reputational damage can hurt just as much.
If a client, landlord, local authority, venue partner, or insurer discovers that your business used non-SIA licensed security guards, trust can drop immediately. In sectors such as hospitality, construction, retail, events, logistics, and commercial property, compliance failures can affect future contract opportunities.
This can lead to:
- Failed supplier audits
- Cancelled contracts
- Negative client feedback
- Damaged professional relationships
- Loss of repeat business
- Poor brand perception
Moreover, many larger clients now expect full evidence of compliance before they approve a supplier. Therefore, using properly licensed guards can support both operational standards and commercial credibility.
How to Check If a Security Guard Has an SIA Licence
Every business should know how to verify a security guard’s licence before work begins.
GOV.UK provides an official service where employers can search the register of SIA licence holders and check whether someone has a licence for roles such as security guard, door supervisor, and CCTV operator.
Before deployment, check:
- The guard’s full name
- The licence number
- The licence type
- The licence expiry date
- The licence status
- Whether the licence matches the role
- Whether the person on site matches the licence holder
You should also keep a record of these checks. This gives your business a stronger audit trail if a client, insurer, or regulator asks for evidence later.
Red Flags When Hiring Security Guards
Not every low-cost provider is a good choice. Although price matters, compliance should come first.
Watch out for these warning signs:
- The provider refuses to share licence details
- Guards arrive without visible SIA badges
- Staff change frequently without notice
- The quote looks unusually cheap
- The company cannot explain its vetting process
- The provider gives vague answers about insurance
- No written contract or service agreement exists
- The company claims approval without evidence
In addition, be careful with last-minute cover. Urgent staffing should still follow the same legal and compliance checks.
What Businesses Should Ask Before Hiring a Security Company
Before you hire a security provider, ask direct compliance questions. This helps you separate professional companies from risky operators.
Useful questions include:
- Are all guards SIA licensed for the roles they perform?
- Do you check licence status before deployment?
- Can you provide licence records if requested?
- Do you hold appropriate insurance?
- How do you vet your security staff?
- What happens if a guard’s licence expires?
- Do supervisors carry out site checks?
- Can you support urgent cover without cutting compliance standards?
These questions protect your business and also show the provider that you take compliance seriously.
Why Choose an SIA-Compliant Security Provider?
A compliant security company does more than send guards to site. It manages vetting, licensing, documentation, supervision, and operational standards.
This matters because your business needs more than labour cover. You need security staff who can represent your site professionally, follow procedures, handle incidents correctly, and meet legal expectations.
A professional provider should offer:
- SIA licensed security officers
- Right-to-work checks
- Licence verification
- Role-specific staffing
- Insurance documentation
- Site assignment instructions
- Clear communication
- Consistent supervision
- Transparent compliance records
As a result, you reduce risk while improving service quality.

What Should You Do If You Suspect a Guard Is Unlicensed?
If you suspect that a guard does not hold the correct SIA licence, act quickly.
First, ask for the licence details and check them through the official SIA register. Next, remove the person from licensable duties until you confirm their status. After that, review your contract, inform the provider, and document what happened.
You may also need to review insurance obligations, notify senior management, and strengthen your hiring process.
Most importantly, do not ignore the issue. A quick check now can prevent a much larger problem later.
Final Thoughts: SIA Compliance Is Not Optional
Using non-SIA licensed security guards may seem like a quick fix, especially when shifts need urgent cover. However, the risks can far outweigh any short-term saving.
A business can face legal action, insurance complications, failed audits, contract losses, and reputational damage. Therefore, every UK business should check licensing before hiring guards and work with a security provider that takes compliance seriously.

FAQs:
How do I check if a security guard has an SIA licence?
You can check a security guard’s licence through the official SIA licence register on GOV.UK. You should confirm the licence number, status, expiry date, and licence type before the guard starts work.
Who is liable if a business uses non-SIA licensed security guards?
The guard may face action, but the business can also face consequences if it employs or deploys unlicensed staff for licensable work. The SIA lists employing unlicensed people in licensable conduct as a criminal offence.
Can using unlicensed security guards affect insurance?
Yes. If an incident happens and the security staff were not properly licensed, insurers may question whether the business met policy conditions. This can create claim delays, disputes, or rejected claims depending on the policy wording.
Are all security guards required to have an SIA licence?
Most frontline private security roles in the UK require an SIA licence. However, the exact requirement depends on the activity and role. Businesses should check the role against SIA guidance before hiring.
What should I ask a security company before hiring them?
Ask whether all guards hold valid SIA licences, how often licences are checked, whether the company can provide compliance records, and whether the provider holds suitable insurance.
Why should I use an SIA-compliant security company?
An SIA-compliant company helps reduce legal, insurance, and operational risks. It also gives your business clearer documentation, better staff vetting, and a more professional service.
