So, you’ve landed in Blighty, or perhaps you’re planning your big move across the pond, and you’ve got an itch to be your own boss. That’s fantastic! The United Kingdom is a hub for innovation, creativity, and commerce. However, navigating the bureaucratic maze in a new country can feel a bit like trying to understand cricket rules on your first day—confusing and slightly overwhelming.
Don’t worry, grab a cuppa and settle in. This Expat guide to starting a business in UK is here to break it all down for you, keeping things simple, actionable, and hopefully, a little fun.
1. Check Your Visa Status (The Important Stuff)
Before you print your business cards, you need to ensure you are legally allowed to run a business here. Not all visas permit self-employment.
If you are already in the UK on a standard work visa (Skilled Worker), you usually can’t be self-employed in a way that interferes with your sponsored job, although there are exceptions for supplementary work. If you are looking to come to the UK specifically to launch a startup, look into:
- Innovator Founder Visa: For those with a unique business idea endorsed by an approved body.
- Global Talent Visa: For leaders in academia, research, arts, or digital technology.
2. Choose Your Business Structure
Just like back home, you need to decide how you want to trade. In the UK, the three most common structures are:
- Sole Trader: The easiest route. You and your business are the same legal entity. You keep all profits after tax, but you’re personally liable for debts.
- Limited Company (Ltd): The most popular choice for serious startups. The business is a separate legal entity. It involves more paperwork, but it protects your personal assets.
- Partnership: Similar to a sole trader, but you share the responsibility (and profits) with a partner.
For this Expat guide to starting a business in UK, we generally recommend considering a Limited Company if you plan to scale, as it offers better protection and tax efficiency down the line.
3. Registering Your Business
If you go the Limited Company route, you need to register with Companies House. It costs as little as £12 if you do it online, and it’s surprisingly fast.
You will need:
- A unique company name (check the Companies House register to ensure it’s not taken).
- An official UK address (this is public record).
- At least one director and one shareholder.

4. Taxes and The Tax Man (HMRC)
Ah, the inevitable taxes. In the UK, the tax authority is called HMRC (Her Majesty’s Revenue and Customs). Once you start trading, you need to register for Corporation Tax (if you are a Ltd Company) or Self-Assessment (if you are a Sole Trader).
Key things to remember:
- VAT: If your turnover exceeds £85,000, you must register for VAT.
- PAYE: If you hire employees, you need to set up a payroll system.
5. Opening a Business Bank Account
We won’t lie to you—this can be the trickiest part for expats. Traditional high street banks often require strict proof of address and credit history in the UK.
However, the rise of fintech has been a lifesaver. Look into digital-first banks like Monzo, Starling, or Revolut Business. They are often much friendlier to new arrivals and allow you to set up accounts via an app in minutes.
6. Business Insurance
Depending on your trade, you might need insurance. If you hire staff, Employers’ Liability Insurance is a legal requirement. Professional Indemnity and Public Liability are also smart moves to protect your hard work.
Final Thoughts
Starting a venture in a new country is a brave move. It requires grit, patience, and a lot of tea. But with the right preparation and by following this Expat guide to starting a business in UK, you are setting yourself up for success. The UK market is diverse and welcoming to innovation—so go out there and make your mark!
