Whether you are a first-time entrepreneur or an experienced business owner expanding internationally, this guide will help you start with confidence.
Step 1: Confirm You Are Legally Allowed to Run a Business
Before doing anything else, you must ensure that your immigration status allows business activity in the UK. This is the most critical step for expats.
Visas That Allow Business Activity
- Innovator Founder Visa – For entrepreneurs with innovative and scalable ideas

- Indefinite Leave to Remain (ILR) – No restrictions on business activity
Visas That Do NOT Allow Business Operations
- Standard Visitor Visa
- Tourist Visa
⚠️ You may own shares in a UK company from abroad, but actively managing or running a business requires the correct visa.
If you are unsure, consult an immigration advisor before proceeding.
Step 2: Decide What Type of Business You Want to Start
Clearly defining your business idea early will make all later steps easier.
Ask yourself:
- What products or services will you offer?

- Is your business regulated?
Understanding your business model helps determine:

Step 3: Choose the Right Legal Structure
The UK offers several business structures. Choosing the right one affects liability, taxes, credibility, and scalability.
