Setting Up in the UK from Finland
Finland has produced a disproportionate number of globally recognised technology companies for a country of 5.5 million people — mobile gaming, cleantech and enterprise software chief among them — and the UK is very often the first serious international market Finnish founders tackle once they've proven the product at home. English fluency is high, the cultural distance is small, and the UK's investor base is a natural fit for Finnish scale-ups outgrowing Nordic funding rounds. The friction shows up in the paperwork: a Finnish osakeyhtiö (Oy) looks like a UK Limited Company on the surface, but the filing regime and thresholds are genuinely different.
Why Finland businesses choose the UK
- Finland ranked among the top ten European countries by per capita FDI into the UK in 2024–25, alongside Sweden, Denmark, Norway and Austria
- A strong track record of Finnish gaming, cleantech and enterprise software companies scaling internationally through London and the UK investor base
- English-language business operations from day one, with minimal translation or localisation overhead
- The UK market gives Finnish companies access to a customer base and capital pool many times larger than Finland's domestic market alone
Oy vs UK Limited Company
| Finnish Oy | UK Limited Company | |
|---|---|---|
| Liability | Limited | Limited |
| Minimum share capital | €2,500 | £1 (no statutory minimum) |
| Filing body | Finnish Patent and Registration Office (PRH) | Companies House |
| Ongoing filings | Annual accounts to PRH | Annual confirmation statement + accounts to Companies House |
| Officer requirement | Board of directors, EEA residency considerations apply | At least one director (can be non-UK resident) |
Most Finnish companies expanding into the UK set up a UK subsidiary, keeping the Oy as the parent holding entity — this is the standard structure for Finnish scale-ups building a UK commercial or engineering presence while retaining core IP and R&D in Finland. Finland and the UK have a double taxation treaty in place, so profits aren't taxed twice, though how R&D tax credits, IP location and intercompany charges are structured is worth a proper conversation given how central R&D incentives are to Finnish tech company economics.

The setup process, step by step
- 01Company registration — incorporating your UK entity with Companies House, typically completed within 24–48 hours once documentation is ready Read our Company Registration Checklist guide →
- 02Registered office — every UK company needs a UK registered office address; a virtual office solves this if you don't yet have UK premises
- 03PAYE and HMRC registration — required as soon as you have UK employees, including a Finnish founder drawing a UK salary Read our How to Register as a UK Employer (PAYE) When You Do Not Have a UK Address guide →
- 04UK business bank account — often the slowest step for Finnish-owned entities, since UK banks apply their own KYC checks to foreign-owned companies Read our Business Bank Account for Non-Residents: What Actually Works guide →
- 05Ongoing compliance — annual accounts, confirmation statements, and corporation tax returns, all on a UK filing calendar independent of your PRH deadlines
Common questions from Finland founders
Should our UK entity hold any of the IP, or should that stay in Finland?
Most Finnish scale-ups keep core IP in the Oy and license or charge the UK subsidiary for use — this affects both UK corporation tax and Finnish R&D incentive eligibility, so it's worth structuring deliberately rather than defaulting.
Can we run UK payroll from our Finnish HR/payroll provider?
No — UK employees need to be paid through a PAYE-registered UK payroll, with UK-specific deductions for tax, National Insurance, and pension auto-enrolment that don't map onto Finnish payroll systems.
Do we need a UK-resident director?
Not legally — a UK subsidiary can have entirely Finland-resident directors, though many groups appoint a UK-based director or authorised signatory to smooth banking and day-to-day administration.
How does the UK–Finland double taxation treaty affect profit repatriation?
It prevents double taxation on the same profit, but the practical mechanics depend on your specific group structure and are worth checking before you set dividend or management charge policies.
