How to Register as a Self-Employed Security Professional in the UK

The UK security industry is filled those who chose the self-employed route; door supervisors, close protection operatives, event stewards, CCTV operators and more. Many are registered as self-employed and contracted by agencies or venues. But figuring out what you need to run legally and professionally isn’t always straightforward.

You’ll need to let HMRC know you’re self-employed. Here’s exactly how to register — step-by-step.

✅ Step 1: Understand Who Needs to Register

You need to register as self-employed if:

  • You earned £1,000 or more from self-employment in the last tax year
  • You run your own business and aren’t employed by someone else
  • You want to submit a Self Assessment tax return to declare your earnings

Even part-time freelancers or people who did security as a side job must register.

🧑‍💻 Step 2: Create a Government Gateway Account

Before registering, you’ll need a Government Gateway account:

  1. Visit gov.uk/sign-in-gateway
  2. Click ‘Create sign in details’
  3. Enter your email address, full name, and create a password

You’ll receive a Government Gateway user ID — keep this safe.

📝 Step 3: Register as Self-Employed with HMRC

Now you can register with HMRC:

  1. Go to gov.uk/register-for-self-assessment
  2. Choose ‘Register if you’re self-employed’
  3. Sign in with your Government Gateway ID
  4. Complete the online form (name, NI number, address, nature of business)

You’ll receive:

Access to file your first Self Assessment return online

A Unique Taxpayer Reference (UTR) by post within 10 days.

📅 Deadlines to Know

  • You must register by 5 October following the end of the tax year in which you started trading
  • Example: If you started freelance work in July 2025, register by 5 October 2026

📌 Final Tips

Keep records from Day 1 (invoices, expenses, mileage, etc.)

Consider tools like business bank accounts and basic accounting software
