What You Need to Go Freelance in the UK (Checklist 2026)

Starting a freelance business in the UK is easier than many people think, but there are a few key things you need to set up properly.

This checklist covers the essential steps every freelancer should take before taking on clients, including tax registration, insurance, accounting tools, and basic business setup.


1. Register as Self-Employed

Most freelancers operate as sole traders, meaning you register with HMRC and file a self-assessment tax return each year.

You should register once you start earning income from freelance work.

Key things to know:

  • HMRC will issue a Unique Taxpayer Reference (UTR)

  • You’ll need to file self-assessment each year

  • You’ll pay income tax and National Insurance

2. Set Up Accounting & Invoicing

Keeping track of income and expenses is critical from day one.

Many freelancers start with spreadsheets, but accounting software saves time and reduces mistakes — especially during tax season.

Tools like QuickBooks allow you to:

  • Send professional invoices

  • Track income and expenses automatically

  • Connect to UK bank accounts

  • Prepare records for self-assessment

3. Get the Right Insurance

Freelancers are personally responsible if something goes wrong. Insurance protects your income and reputation.

Common policies include:

Public Liability Insurance

  • Covers injury or property damage claims

Professional Indemnity Insurance

  • Covers advice, services, or mistakes that cause financial loss

Tools & Equipment Insurance

  • Covers theft or damage to work equipment

4. Open a Separate Business Bank Account

While not legally required for sole traders, separating finances makes accounting much easier.

Benefits include:

  • Clear income and expense tracking

  • Easier tax preparation

  • Professional payments from clients

Many freelancers combine a business bank account with accounting software to automate bookkeeping.

5. Create a Simple Contract

Every freelancer should have a basic contract that covers:

  • Scope of work

  • Payment terms

  • Deadlines

  • Cancellation terms

Even simple agreements can prevent disputes later.

6. Decide How You’ll Track Expenses

Expenses reduce your taxable profit, so keeping accurate records matters.

Common deductible expenses include:

  • Software subscriptions

  • Business travel

  • Equipment and tools

  • Phone and internet use for work
