Would you like to set up a company in the United Kingdom? ICD Fiduciaries can assist you in choosing the right structure, completing the incorporation formalities and putting the services required to launch your business in place.

Why Set Up a Business in the United Kingdom?

The United Kingdom remains one of the leading international markets for companies looking to expand their activities across Europe and internationally.

Its economy is strongly service-oriented, with particularly important sectors including finance, business services, technology, international trade, insurance and professional services.

According to the latest estimates from the Office for National Statistics, the British economy grew by 1.2% over the whole of 2025, while real GDP per capita increased by 0.4% in the second quarter of 2026 compared with the previous quarter.

The UK also remains a major destination for international investment. According to the ONS, the stock of foreign direct investment held in the UK by non-resident companies reached £2,127.6 billion at the end of 2024.

For an entrepreneur or foreign company, establishing a UK presence can offer several advantages, including the ability to:

• Establish a legal structure recognised internationally.
• Access the British market.
• Develop an international customer base.
• Establish a presence in London or another part of the United Kingdom.
• Facilitate certain business relationships with British partners.
• Recruit locally.
• Develop a remote service-based business.
• Structure international activities within a common-law legal environment.

However, the United Kingdom is no longer a member of the European Union. A British company working with European customers or suppliers must therefore take account of the rules governing trade between the UK and the EU, particularly those relating to VAT, customs, data, contracts and sector-specific regulations.

• Foreign entrepreneurs.
• SMEs and international groups.
• Investors.
• Consultants and service companies.
• Technology companies.
• Businesses looking to open a UK subsidiary.
• Companies seeking to establish a presence in London.
• Business leaders looking for registered office and administration services in the UK.

Our objective is simple: to help you focus on your commercial activities while we assist you in structuring and administering your British presence.

Our Solutions for Establishing Your Business in the United Kingdom

British Company Formation

We help you identify the appropriate legal structure and complete the procedures required to incorporate your company.

Depending on your project, several options may be considered:

• Private Limited Company (Ltd)
• Public Limited Company (PLC)
• Limited Liability Partnership (LLP)
• Branch or establishment of a foreign company.
• Other structures suited to specific requirements.

The Private Company Limited by Shares is the most commonly used structure for commercial businesses. It has a legal personality separate from that of its owners.

The choice of structure depends on factors including the business activity, number of shareholders, proposed financing, governance, taxation and planned international expansion.

Registered Office and Business Address Services in the United Kingdom

A British company must have a registered office, which is its official address for receiving communications and documents addressed to the company.

Under recent changes to British company law, this must be an appropriate physical address located in the same part of the United Kingdom in which the company is registered. A simple PO box cannot be used as a registered office.

ICD Fiduciaries can provide a registered office and business address service, subject to the requirements applicable to your case.

A registered address service can be particularly useful for an international entrepreneur who does not yet have premises in the UK.

It can help separate the director’s personal address from the company’s official address while complying with British requirements.

The registered office address is published on the Companies House public register.

Directors and Corporate Governance

The governance of a British company must be organised in accordance with the Companies Act 2006 and the rules applicable to the chosen structure.

A private company can generally be incorporated with a single natural-person director. A company secretary is not usually required for a private limited company unless the articles of association provide otherwise.

Directors must comply with their legal duties and act in the interests of the company.

Since 18 November 2025, identity verification for directors and people with significant control (PSCs) has formed part of the new obligations introduced through the Companies House reforms.

ICD Fiduciaries can assist with the preparation and coordination of the necessary administrative formalities.

Company Secretarial and Compliance Services

A British company requires more than a certificate of incorporation.

Once established, it must comply with various filing, governance, accounting and tax obligations.

Our services may include:

• Managing administrative obligations.
• Company secretarial services.
• Monitoring deadlines.
• Preparing and coordinating filings with Companies House.
• Document management.
• Assistance for directors.
• Maintaining statutory company records.
• Coordinating with legal and tax professionals.
• Corporate compliance support.

A British company must keep its information up to date with Companies House and file the required documents, including its confirmation statement and accounts where applicable.

Accounting and Financial Reporting in the United Kingdom

Accounting is an essential part of a British company’s compliance obligations.

ICD Fiduciaries can assist with:

• Bookkeeping.
• Preparation of annual financial statements.
• Financial reporting.
• Consolidation.
• Preparing information required for tax returns.
• Coordination with auditors.
• Monitoring accounting and tax deadlines.

The exact requirements depend on factors including the company’s size, legal form, business activities and accounting regime.

Audit Exemption: What Are the Rules in 2026?

Older information referring to thresholds of £10.2 million in turnover and £5.1 million in assets is no longer up to date for the relevant financial years.

For financial years beginning on or after 6 April 2025, a private company can generally qualify for an audit exemption if it meets at least two of the following three criteria:

• Annual turnover not exceeding £15 million.
• Balance sheet total not exceeding £7.5 million.
• An average of 50 employees or fewer.

Certain circumstances may nevertheless require an audit, including where the company’s articles of association or shareholders require one, or where another legal obligation applies.

Corporate Taxation in the United Kingdom

UK taxation should be considered before incorporating a company to avoid choosing an unsuitable structure.

For the relevant financial years in 2026, the main rate of Corporation Tax is 25%.

The small profits rate is 19% for profits not exceeding £50,000. Marginal relief generally applies where profits fall between £50,000 and £250,000, subject in particular to the rules concerning associated companies.

The tax rate should not, however, be the sole basis for making a decision.

Tax treatment depends on several factors, including:

• Tax residence.
• The nature of the business activities.
• Where operations take place.
• Directors and employees.
• International cash flows.
• Intra-group transactions.
• VAT.
• Tax treaties.
• Transfer pricing rules.
• Ownership structure.

A personalised tax assessment is therefore recommended before making any structuring decisions.

Opening a Business Bank Account

To develop a business in the UK, a company may need a business bank account or an appropriate payment solution.

ICD Fiduciaries can assist with preparing the application and coordinating the account-opening process.

However, opening an account remains subject to the decision of the relevant bank or financial institution and its own Know Your Customer (KYC), anti-money laundering and business verification procedures.

Virtual Office and Commercial Presence in London

For an international company looking to test the British market without immediately renting premises, a virtual office in the United Kingdom can provide a flexible solution.

Depending on your requirements, an administrative presence can be supplemented with:

• A professional business address.
• Mail receipt and handling.
• Administrative services.
• Telephone answering services.
• Meeting rooms.
• Back-office services.
• Business setup assistance.

The aim is to establish a professional presence in the UK without immediately taking on the fixed costs associated with a traditional office.

International Trade and Financial Operations

The United Kingdom has a well-developed environment for businesses engaged in international trade.

Depending on your business activities and subject to applicable regulations, ICD Fiduciaries can assist with matters such as:

• International commercial transactions.
• Commercial documentation.
• Letters of credit.
• International invoicing.
• Financial flows.
• Banking coordination.
• Relationships with business partners.
• Administrative structuring of transactions.

Regulated activities, particularly in financial services, require a specific assessment of the applicable authorisation and compliance requirements.

Intellectual Property

For an international company, intellectual property is often a strategic asset.

ICD Fiduciaries can assist with coordinating procedures relating to:

• Trademarks.
• Patents.
• Licences.
• Royalties.
• Administrative structuring of intangible assets.

Intellectual property and international tax matters should be assessed on a case-by-case basis, particularly when assets or companies are located in multiple jurisdictions.

Immigration and Work Permits in the United Kingdom

Incorporating a British company does not automatically grant the right to live or work in the United Kingdom.

Foreign entrepreneurs and employees must determine which immigration rules apply to them before starting work in the UK.

ICD Fiduciaries can assist with administrative preparation and coordinate your application, working with the relevant specialists where necessary.

Commercial Property in the United Kingdom

A business may need premises for employees, client meetings, storage or operational activities.

We can assist with coordinating projects relating to:

• Finding suitable premises.
• Setting up an office.
• Commercial leasing.
• Acquiring business property.
• Administrative management of certain property assets.

The legal and tax implications of a purchase or lease should be checked with the appropriate professionals.

The Main Types of Company Structure in the United Kingdom

Private Limited Company – Ltd

The Ltd is generally the preferred structure for an SME, service company, commercial business or UK subsidiary.

A private company limited by shares has a legal personality separate from its shareholders. Shareholders’ liability is generally limited to any amount unpaid on their shares.

It may be suitable for:

• Entrepreneurs.
• Consultants.
• Service companies.
• Technology businesses.
• International trading companies.
• Subsidiaries of foreign groups.

Public Limited Company – PLC

A PLC is a public company subject to more extensive governance and financing requirements.

It may be suitable for certain larger businesses or companies with specific financing needs or plans to access the capital markets.

Incorporating a PLC requires a more detailed assessment of the structure, share capital, governance and regulatory obligations.

Limited Liability Partnership – LLP

An LLP combines certain characteristics of a partnership with limited liability.

It may be used by certain professional businesses and structures involving multiple partners.

Its suitability depends heavily on the partners’ legal and tax circumstances.

Branch of a Foreign Company

A foreign business may also choose to establish a presence in the United Kingdom without necessarily incorporating a new British subsidiary.

The choice between a subsidiary, branch or another form of establishment depends on factors including the planned level of activity, taxation, legal liability and commercial objectives.

How Do You Set Up a Company in the United Kingdom?

Setting up a British company generally involves several steps.

1. Define Your Business Project

We assess the following with you:

• Your business activity.
• Your country of residence.
• Your target markets.
• Your shareholders or partners.
• Your banking requirements.
• Your administrative needs.
• Your recruitment plans.
• Your growth objectives.

2. Choose the Structure

We identify the legal structure best suited to your project: Ltd, PLC, LLP, branch or another solution.

3. Choose the Company Name

The proposed name must comply with Companies House rules and must not conflict with an existing or protected name.

4. Establish the Registered Office

The registered office must comply with British requirements and be located in the appropriate part of the United Kingdom.

5. Identify the Directors and Beneficial Owners

Information concerning directors and People with Significant Control (PSCs) must be provided in accordance with the applicable rules.

Mandatory identity verification is now an important part of the compliance process.

6. Incorporate the Company

Incorporation takes place through Companies House.

The company legally exists as an incorporated company once the certificate of incorporation has been issued.

7. Put Operational Services in Place

Once the company has been incorporated, we can assist you in setting up:

• Registered office services.
• Accounting.
• Company secretarial services.
• Banking.
• Financial reporting.
• Administration.
• Tax support.
• Virtual office services.
• Commercial assistance.

Why Does London Remain a Strategic Choice?

London is a particularly attractive environment for international businesses thanks to its financial, professional and entrepreneurial ecosystem.

The British capital is home to:

• International financial institutions.
• Banks.
• Law firms.
• Consulting firms.
• Investment funds.
• Technology companies.
• Start-ups.
• International headquarters.
• Professional and business networks.

For a foreign company, establishing a presence in London can also help build an international profile and provide access to a well-developed professional network.

However, London is not necessarily the best location for every business. The choice of location should take into account property costs, employees, local taxation, logistics, customers and the nature of the business.

Understanding Business Culture in the United Kingdom

Commercial success in the UK depends on more than the legal structure.

British business culture generally values:

• Punctuality.
• Reliability.
• Preparation.
• Courtesy.
• Clarity.
• Keeping commitments.
• Professional communication that is often less demonstrative.
• Building relationships of trust over time.

Highly aggressive sales techniques can be counterproductive in some professional environments.

An approach based on credibility, added value, precision and long-term relationships is often more effective.

However, generalisations should be avoided: practices vary considerably across industries, regions, companies and individuals.

FAQ – Setting Up a Business in the United Kingdom

Can a foreign national set up a company in the United Kingdom?

Yes. Foreign entrepreneurs can incorporate a British company, provided they comply with the applicable legal, administrative and compliance requirements. However, incorporating a British company does not automatically grant its director the right to reside or work in the UK.

What is the best structure for setting up a business in the United Kingdom?

For many entrepreneurs and SMEs, the Private Limited Company (Ltd) is a common and flexible structure. However, an LLP, PLC, branch or another structure may be more appropriate depending on the project.

The choice should take into account the business activity, shareholders, taxation, financing and international development plans.

Do I need to live in the United Kingdom to set up a Ltd?

UK residence is not, in itself, a general requirement for becoming a shareholder in a Ltd. However, the company must comply with the rules concerning its registered office, directors, PSCs and other compliance obligations.

Can I set up a company in the United Kingdom without having an office?

Yes. A company can have a registered office that is separate from its operational address. However, the registered office must comply with British requirements, including being an appropriate physical address in the part of the UK where the company is registered.

Can I use a registered address service for a British company?

Yes, provided that the proposed address meets the legal requirements for a registered office and the service provider is authorised to provide it for that purpose.

Since the registered office address is publicly available, a registered address service can also help avoid using the director’s personal address as the company’s public address where this is not desired.

What is the rate of Corporation Tax in the United Kingdom?

In 2026, the main rate of Corporation Tax is 25%. The small profits rate is 19% for profits not exceeding £50,000, with marginal relief applying between £50,000 and £250,000, subject to certain conditions.
