How to Become a Self-Employed Security Officer in the UK (2025 Guide)


Many security professionals in the UK choose to work self-employed. It offers flexibility and independence, but there are important legal steps to follow. This guide explains exactly what you need to do to go self-employed as a security guard or Door Supervisor.

Do You Need an SIA Licence?

Yes — regardless of whether you work for an employer or as a self-employed contractor, you must hold a valid SIA Licence for security roles like:

  • Door Supervisor
  • Security Guard
  • CCTV Operator

Step 1: Register as Self-Employed

To work legally as self-employed in the UK, you must:

  • Register with HMRC as self-employed
  • Keep accurate records of your income and expenses
  • File a Self Assessment tax return each year

Step 2: Consider Insurance

Many companies will only hire self-employed security workers if you have:

✔ Public Liability Insurance

✔ Professional Indemnity Insurance (optional but recommended)

You can compare insurance options at Freelance Cover.

Step 3: Find Legitimate Work

Most self-employed security guards find work through:

  • Security agencies hiring subcontractors
  • Direct contracts with event organisers or venues
  • Word of mouth within the industry

Be cautious of unlicensed work or unrealistic promises — always check client credibility.

Step 4: Understand Your Responsibilities

As self-employed, you’re responsible for:

✔ Your own tax and National Insurance

✔ Providing your own equipment (if required)

✔ Ensuring your licence and training are up to date

Is Self-Employment Right for You?

Self-employment offers:

  • More control over your work
  • Flexibility with hours and clients
  • Potential for higher earnings

But it also means:

You need to find work consistently

No guaranteed income

You handle your own admin and tax

Final Thoughts

If you’re organised and motivated, becoming a self-employed security guard can be a great option. Just make sure you stay compliant, insured, and realistic about the work.
