Expanding into the UK requires an early decision about how the business will enter the market, operate locally and manage the legal and regulatory differences between the UK and EU.
EU businesses should now treat the UK as a separate legal and regulatory market, particularly in relation to immigration, customs, data, employment and product or sector regulation.
With tailored advice from our commercial law solicitors, you can structure your UK presence with confidence, whether you’re setting up a subsidiary, navigating cross-border trading rules or managing employment law obligations.
Our team will support you to make legally sound decisions that align with your business strategy and future growth plans.

How could an EU business enter the UK market?
If you’re an EU business owner, you may think that once you've worked out the business pros and cons and the costs, buying or renting commercial premises or office space in the UK is straightforward.
However, while commercial property solicitors can help your company buy or rent the right UK office or business premises, you first need to think about the company structure of your UK base and how you plan to staff the offices.
Initially, you’ll need some expert accountancy and corporate law advice on your company structure options. From a legal or financial perspective, it may be best for your EU-based company to set up a UK branch or a wholly owned subsidiary company of your EU parent company.
The appropriate structure will depend on factors including:
- liability
- tax
- regulatory requirements
- reporting obligations
- customers’ expectations
- the group’s longer-term UK strategy
Once you know what type of company or partnership structure best meets your short-term and long-term business expansion goals, the next practical consideration is where you should base your offices in the UK.
That decision may come down to the nature of your business, any geographic or transportation needs, or the importance of being located or clustered near other digital or tech companies so that you can benefit from their success and the ready availability of skilled workers or component parts.
Financial incentives may also play a key role in your decision-making. In certain parts of the UK, grants and funding are available to overseas companies seeking to invest here.
The availability of these incentives often depends on factors such as the nature of your business, the proposed location of your UK office, and the number of jobs you plan to create. Examples include:
- funding schemes from Innovate UK Business Connect
- government-backed innovation competitions
- official UK Government advice for businesses looking to expand into the UK
Do you need to register your EU company in the UK?
Broadly speaking, if your existing EU company opens a physical establishment in the UK, it will normally need to register with Companies House within one month.
Merely selling to UK customers from the EU doesn't necessarily create a registrable establishment, so the practical arrangements matter.
Registration and ongoing filing requirements may include information about:
- the overseas company and its constitution
- its directors and other officers
- the UK establishment
- the people authorised to represent the company in the UK
- the overseas company’s accounts
Companies House identity verification requirements must also be built into your timetable. Failing to plan for registration, document certification or identity checks can hold up a launch that otherwise looks commercially ready.
A UK subsidiary follows a different incorporation and reporting process. You’ll also need tax advice on matters such as corporation tax, VAT, transfer pricing, payroll and whether activities in the UK could create a taxable permanent establishment.
Staffing your UK office
You’ll need to decide whether to recruit in the UK, relocate existing employees or use a combination of both.
British and Irish citizens and people who already hold suitable UK immigration status may be able to work without employer sponsorship. Other EU nationals are generally subject to the same immigration system as nationals from outside the European Economic Area (EEA).
The fact that a person can visit the UK doesn’t mean they can automatically work here. Many EU nationals can visit for up to six months without getting a visitor visa, but they’ll usually need an Electronic Travel Authorisation before travelling unless an exemption applies.
Visitor rules permit specified activities such as attending meetings, negotiating contracts, visiting sites and gathering information for overseas employment. They do not normally allow someone to take general employment or base themselves in the UK to run the new operation.
Before travel, check the person’s nationality, immigration status and proposed activities. A visit to assess premises is very different from taking day-to-day responsibility for UK sales, staff and operations.
Business immigration and setting up a UK office
If you decide to set up a UK branch or subsidiary of your EU parent company, it’s likely you’ll want someone to head up the UK office who knows and understands your business and how best to operate it from the UK, rather than recruit someone in the UK who may know how UK businesses operate but doesn’t have the knowledge and experience of your particular business.
Unless the person (or staff) selected to head up and work in the UK office is a British citizen or has settled status through indefinite leave to remain or under the EU Settlement Scheme, they will require a business visa or work visa under the UK points-based immigration system operated by the Home Office (also referred to as UK Visas and Immigration or UKVI).
Where the overseas business hasn’t yet started trading in the UK, the Global Business Mobility: UK Expansion Worker route may allow eligible senior managers or specialist employees to undertake work connected with establishing a UK branch or subsidiary, subject to detailed eligibility, overseas employment and salary requirements.
It’s a temporary sponsored route, and the overseas business, UK expansion and individual must meet these detailed eligibility requirements.
If you choose to employ a British citizen, or a person with settled status, to run your office, you may still want to make sure that the UK branch or subsidiary adopts your business practices.
This can be difficult without an ‘on ground’ physical presence, but it can be achieved through the UK branch of your EU based company applying to the Home Office for a sponsor licence.
Once the UK business is trading and has the appropriate sponsor licence, the Global Business Mobility: Senior or Specialist Worker route may be available for an eligible senior manager or specialist employee assigned by a linked overseas business. Depending on the role and circumstances, the Skilled Worker route may instead be more appropriate.
As your UK office expands, your business may need more employees. One concern may be whether your company will be able to recruit suitable candidates due to the UK skills shortage.
If the UK branch of your company applies to the Home Office for a sponsor licence, the UK office will be able to recruit job applicants from EU and non-EEA countries who are subject to immigration controls. That can be achieved by the UK office sponsoring skilled migrant workers to work for the company on skilled worker visas.
It’s best to understand the sponsorship process from the outset of setting up a UK office, so your business is geared up to be able to recruit the employees you need in the UK with the requisite skills and experience.
As well as potential visa requirements, all employees, regardless of nationality or immigration status, need to pass a right to work check before commencing employment in the UK to prevent illegal working.
Providing services to the UK
If your EU-based business is in the services sector and you’re planning to set up an office, branch or subsidiary company in the UK, you’ll need expert legal advice on UK regulations relevant to your industry sector.
For example, if your business is providing financial or insurance-related services, you’ll need to comply with the relevant requirements set down by the Financial Conduct Authority or other regulatory bodies.
If your business is in the personal services industry, as well as checking the UK regulations around providing the service you’ll be offering, your commercial solicitors will also need to ascertain if you’ll need:
- a licence from the local authority to set up a UK-based business, or
- change of use planning permission to operate your service-based business from specific commercial premises
Data protection
An EU business with UK operations may need to comply with both the EU General Data Protection Regulation and the UK General Data Protection Regulation (GDPR).
The answer depends on where the relevant entities are established, whose personal information is being handled and which individuals are being offered goods or services or monitored. The UK framework also includes the Data Protection Act 2018 and the Privacy and Electronic Communications Regulations.
The Data (Use and Access) Act 2025 has amended this framework. Its data protection provisions came into force in stages, with all those provisions in force by June 2026.
It modifies rather than replaces the UK GDPR, the Data Protection Act 2018 and the Privacy and Electronic Communications Regulations.
The European Commission renewed the UK’s adequacy decisions on 19 December 2025. They currently allow personal data covered by the decisions to flow from the EEA to the UK without further transfer safeguards and are due to remain in force until 27 December 2031, subject to ongoing monitoring.
Adequacy makes many transfers into the UK simpler, but it doesn’t remove your wider compliance obligations. You should still map how personal information will move between group companies, suppliers, customers and platforms.
The review should cover:
- which entity is acting as controller or processor
- lawful bases for processing
- transparency and privacy information
- employee and recruitment data
- direct marketing and cookies
- processor agreements
- security and breach-response arrangements
- retention periods
- transfers from the UK or EU to other countries
- whether a UK or EU representative is required
Commercial agreements and intra-group data-sharing arrangements should reflect how information is used. A generic data-protection clause copied from an old template may not allocate the parties’ responsibilities properly.
What should you consider when moving goods between the EU and UK?
Goods moving between the EU and Great Britain are subject to customs processes. Before trading starts, decide:
- who will act as importer and exporter of record
- who will complete customs declarations
- which Economic Operators Registration and Identification numbers are needed
- who will pay duty and import VAT
- whether licences, certificates or inspections apply
- who is responsible for product conformity and labelling
- how border delays and rejected shipments will be handled
- which Incoterms will be used in customer and supplier contracts
A Great Britain Economic Operators Registration and Identification number is commonly required for customs activity involving England, Scotland or Wales.
The EU business may also need an EU registration for activities in the EU. The exact registrations depend on where the business is established, and which party carries out the customs formalities.
The UK-EU Trade and Cooperation Agreement does not make every shipment duty-free. For preferential tariff treatment, the goods must meet the relevant rules of origin and the required evidence must be held. Goods that don’t qualify can still be traded, but the standard customs tariff may apply.
Product-specific rules can add another layer. Food, plants, animals, chemicals, medicines, medical devices and other regulated products may be subject to further border and market-access requirements.
Do different rules apply to Northern Ireland?
It’s important not to treat the UK as a single customs and product-regulation territory.
Movements involving Northern Ireland may fall under the Windsor Framework and can follow different rules from movements involving England, Scotland or Wales.
Which process applies will depend on where the goods originate, their final destination and whether they’re considered at risk of entering the EU market.
Businesses trading through Northern Ireland should review the specific customs, VAT, product and labelling rules rather than applying their Great Britain process automatically.
Intellectual property and UK business expansion
Intellectual property (IP) is often overlooked in the rush to establish a new office, despite many business owners understanding its value in the modern era.
Without a strong IP strategy and adequate IP protection, your company brand and reputation are at risk, and that just isn’t acceptable for any international company.
If you’re opening an office in the UK, you need to think about whether any existing patents and IP rights already apply to your business in the UK. If they don’t apply, then you need expert IP legal advice on how to protect your assets best.
Even if your IP is protected in the UK, you also need to think about your long-term business goals and market expansion plans. If the UK office is to serve as the non-EU base for international expansion, your IP in the UK must be capable of protection against any international threats.
Contracts and setting up a UK office
When setting up a UK office of your EU-based company, it’s tempting to assume that you can get your existing commercial contracts translated into English and used as a template by your UK office.
It isn’t as simple as that, as any UK commercial contract will need to take account of relevant UK law.
Where there’s a choice of law and jurisdiction, you’ll need to choose wisely on jurisdiction, with the help of an English commercial solicitor. These provisions can be particularly important if an international commercial dispute later arises.
What are the key steps for a successful UK launch?
Expansion can feel like a long list of registrations and permissions, but the project becomes more manageable when the decisions are taken in the right order.
Start by:
- Defining the commercial model. Decide what you’ll sell, who the UK customers are and how much local control and investment you need.
- Choosing the entry structure. Compare direct trading, an agent or distributor, a UK establishment, a subsidiary and acquisition.
- Mapping the regulatory requirements. Check authorisations, licences, product rules and property requirements before committing to a launch date.
- Planning your people strategy. Identify who will lead the operation, whether they can work in the UK and whether they need sponsorship.
- Reviewing data and supply chains. Understand how personal information and goods will move between the UK, EU and other countries.
- Protecting intellectual property. Check UK availability and ownership before launching the brand.
- Adapting your contracts. Make sure the legal documents match the UK entity, operating model and allocation of commercial risk.
- Setting a realistic timetable. Incorporation can be quick, but immigration, regulatory approval, property and licensing can take considerably longer.
The UK and EU still share many similar legal foundations, but important differences now exist and further divergence can develop over time.
Build periodic legal and regulatory reviews into your expansion plan so that the UK operation does not continue relying on assumptions made at launch.
