Setting up in the UK

The UK remains a compelling destination for overseas businesses looking to establish a foothold in Europe. With its flexible legal structures, investor-friendly regulatory environment and strategic time zone bridging the US and Asia, the UK offers a unique launchpad for international growth. Its thriving tech and start-up ecosystem, as well as access to funding and proximity to key European markets, make it an attractive choice for ambitious enterprises. However, navigating the UK legal landscape from the outset is essential to avoid costly pitfalls – especially when planning future expansion into other jurisdictions.

This guide provides a high-level overview of the most relevant legal considerations when setting up in the UK and outlines how our team can support you every step of the way.

Japanese high-tech company

Expanding into a new market isn’t easy – especially when you’re crossing continents and time zones. That’s exactly what one Japanese high-tech company faced when they decided to expand into the UK market by a strategic acquisition.

We began by explaining UK technical legal concepts in a user friendly way. This gave our client the clarity and confidence they needed from day one for a smoother UK entry.

From there, our Corporate Team brought in the right experts across our firm at every stage – including intellectual property (IP), data protection, employment, immigration, real estate, commercial contracts, disputes and share capital and structure.

Our specialist Data, Privacy and Cybersecurity Team advised on data protection, governance and compliance-related requirements. This meant they were compliant with their regulatory requirements as a data controller.

Then our IP team got to work. We protected their products with trademarks and advised on potential disputes with third parties, so their brand was safe as they expanded.

We also guided our client through delicate employment matters and secured immigration status for key personnel relocating to the UK. This included pre-termination settlements with a senior employee and negotiating terms and paid leave to support smooth transitions.

Our Japanese client successfully acquired the target business with our support and established their UK operations.

US private equity firm

When a US private equity firm needed to set up a UK subsidiary within a tight timeframe – they turned to us.

Our immigration experts secured visas for the US team members and their families. Meanwhile, our corporate lawyers developed a corporate structure and planned activities for the UK subsidiary company that worked for both tax and immigration.

We drafted employment contracts, built HR policies and sourced external staffing support so the client could hit the ground running in the UK.

Our IP Team helped protect the company’s name and logo in the UK, EU, Norway and Switzerland, and gave strategic advice to develop their branding.

Our Property Team offered advice on securing a suitable London office, helping to negotiate leases for their chosen premises.

The result was a seamless, accelerated entry into the UK, with each of our specialist teams working in tandem to help them navigate the complex legal and regulatory environment. This underscores our ability to deliver tailored, multi-disciplinary, full-service legal solutions to help international investors and businesses achieve their ambitious growth goals in the UK and further afield.
