UK Company Registration Checklist for Foreign Businesses

Setting up a UK company as a foreign business owner is more straightforward than most people expect — but the process has a handful of steps that catch overseas founders off guard, particularly around addresses, banking and tax registration. This checklist walks through everything you need, in the order you actually need it, so a company incorporated on Monday can be trading, banked and payroll-ready inside a calendar month.

1. Choose your UK structure

Most foreign SMEs entering the UK register a Private Limited Company (Ltd). It is the simplest structure, offers liability protection, and is well understood by UK banks, clients, suppliers and landlords. A UK branch of your existing overseas company or a representative office are alternatives — but they suit larger operations or specific tax situations rather than a typical SME testing the UK market.

2. Registered office address

Every UK company needs a UK registered office address. It is a public record, does not need to be where you actually work from, and most foreign founders use a registered office service rather than renting premises before they have UK operations up and running. This is the single thing that trips people up most often: you cannot register a UK company with an overseas-only address.

3. Appoint directors and disclose PSCs

UK company law requires at least one director (no UK residency requirement) and disclosure of every Person with Significant Control — anyone who owns more than 25% of the company or otherwise exercises significant control. Foreign parent companies count as PSCs and must be declared. Under 2025 identity-verification rules, every director must also complete Companies House ID verification before the incorporation filing can complete.

4. Register with Companies House

This is the actual incorporation step. You will need:

• A company name (checked for availability and trademark clashes).
• The UK registered office address.
• Director and PSC details for every named person.
• A SIC code describing your business activity.
• Articles of Association (Model Articles work for most SMEs).

Online registration typically completes within 24–48 hours once documents are in order.

5. Register for Corporation Tax

Within three months of starting to trade, the UK company must register with HMRC for Corporation Tax. This is separate from Companies House registration and is often missed by first-time foreign founders because it does not happen automatically.

6. Open a UK business bank account

For non-resident directors, this is usually the slowest step. Traditional high-street banks often require in-person meetings and UK proof of address; digital-first banks are typically faster for overseas founders, but come with their own verification requirements. Plan for banking to take longer than incorporation itself — see our companion guide on UK business banking for non-residents.

7. Register as an employer (PAYE) — if hiring

If you plan to employ anyone in the UK, you must register for PAYE before the first payday. This has its own lead time and documentation requirements, especially without a UK-based HR presence — allow several weeks.

8. VAT registration — if applicable

VAT registration is mandatory once UK taxable turnover exceeds the current threshold, though many foreign companies selling into the UK register voluntarily earlier to reclaim VAT on setup costs. Overseas businesses with no UK establishment selling goods into the UK sometimes have no threshold at all — check your specific situation.
