Company Registration in UK: A Practical 2026 Guide

Starting a company in the UK involves more than submitting an application to Companies House. The founder needs to decide the right legal structure, select an acceptable company name, appoint directors, identify shareholders and people with significant control, arrange a suitable registered office and provide the information required for incorporation.

For most commercial ventures, a private company limited by shares is the structure founders consider first. It creates a legal entity separate from its owners and can provide limited liability. A private limited company must have at least one director and at least one shareholder. A company secretary is optional for most private companies.

The UK registration system is relatively straightforward, but mistakes at the setup stage can create problems later. This is particularly important for overseas founders because company ownership, UK residency, immigration permission and the right to work in the UK are separate issues.

Here is what you should understand before registering a UK company.

Quick answer: What is required to register a UK company?

A typical private limited company registration requires:

• An acceptable company name
• At least one director
• At least one shareholder
• Details of people with significant control
• A suitable UK registered office
• A registered email address
• An appropriate SIC code describing business activities
• Memorandum and articles of association
• Identity verification where required
• Registration with Companies House

Companies House issues a certificate of incorporation once the application is successfully registered.

Choose the right UK company structure

The first decision is not the application form. It is choosing the legal structure.

For many trading businesses, a private company limited by shares is practical because ownership can be represented through shares and the company exists separately from its shareholders.

A company limited by guarantee is generally used for organisations where members provide guarantees rather than holding shares.

For an ordinary commercial venture, founders commonly examine the private limited company option first, then confirm whether another structure better suits their activities, ownership model and tax position.

Who can become a director?

A UK private company needs at least one director. The director must be at least 16 years old.

Importantly, a director does not have to live in the UK. However, the company itself must have an appropriate registered office address in the UK.

This distinction matters for international founders.

For example, an entrepreneur living in India may be able to become a director and shareholder of a UK company without personally living in Britain. However, incorporating a company does not automatically give that person immigration permission or the right to work physically in the UK.

That is why company formation and immigration planning should be treated as separate questions.

Decide who owns the company

A private company limited by shares needs at least one shareholder, and the shareholder can also be a director.

Before registration, founders should determine:

• Who owns the shares
• How many shares each shareholder holds
• Voting rights
• Ownership percentages
• Whether another company will hold shares
• Who ultimately controls the business

Ownership should be decided carefully before incorporation because the share structure affects future investment, decision-making and transfers.

Identify the people with significant control

The UK registration process also requires information about people with significant control, commonly called PSCs.

A PSC can include an individual who holds more than 25% of the shares or voting rights, although other forms of significant control can also be relevant.

For a simple company owned entirely by one founder, the PSC position may be straightforward. More complicated structures involving multiple shareholders, trusts or corporate shareholders require closer analysis.

Getting the ownership and control information right at incorporation is important because Companies House maintains public company information.

Arrange the registered office correctly

A UK company must have a registered office address.

The address must be a physical address in the UK, be in the same country of the UK in which the company is registered, and meet Companies House requirements for an appropriate address. A PO Box cannot be used as the registered office.

The registered office is also publicly available.

This means overseas founders should consider privacy and correspondence management before choosing an address. A professional address may be preferable where appropriate, provided it satisfies the legal requirements.

Choose the correct SIC code

When registering the company, you need to provide a SIC code.

The code describes the company's business activities and helps Companies House classify what the company does.

Founders should avoid choosing a code simply because it sounds similar to their business. The activities stated during incorporation should reasonably reflect the company's intended operations.

For businesses with several activities, selecting appropriate codes is particularly important.

Prepare the incorporation information

The registration application requires information about the company and its people.

Depending on the company structure, this can include:

• Proposed company name
• Registered office
• Registered email address
• Director information
• Shareholder information
• Share details
• PSC information
• SIC code
• Articles of association
• Memorandum of association

For online registration using model articles, the memorandum is created as part of the registration process. Companies using different arrangements may need additional documentation.

Identity verification is now an important part of registration

One of the significant changes affecting UK company formation is identity verification.

Companies House has introduced identity verification requirements, and founders may need to verify their identity and provide the resulting personal code when registering a company. Where there is more than one director, each director may need the relevant personal code.

This makes it important to prepare identity information correctly before submitting the incorporation application.

For overseas founders, the practical process can require additional attention because personal details must match the information supplied to Companies House.

How company registration in UK works

The registration process can generally be approached in this order:

Decide the company structure

Confirm that a private limited company is appropriate for the planned business.

Select the company name

Check whether the proposed name meets Companies House rules and consider existing trademarks before proceeding.

Decide ownership

Confirm shareholders, shareholdings and control arrangements.

Appoint the director or directors

Provide the required director information and complete identity verification where applicable.

Arrange the registered office

Ensure the address satisfies UK Companies House requirements.

Select SIC codes

Choose codes that accurately describe the company's intended activities.

Prepare constitutional documents

Review the memorandum and articles of association and any specific provisions required for the company.

Identify PSCs

Provide accurate information about people who ultimately control the company.

Submit the application

The incorporation application is submitted to Companies House through the applicable registration route.

Receive incorporation confirmation

Once accepted, the company receives a certificate of incorporation confirming that the legal entity exists, together with its company number and formation date.

What happens after UK company registration?

Incorporation is the beginning of the company's compliance responsibilities, not the end.

After registration, the directors should establish appropriate accounting and corporate records and monitor filing deadlines.

The company may need to deal with:

• Corporation Tax registration and reporting
• Annual accounts
• Confirmation statements
• Changes to directors or shareholders where applicable
• Changes to PSC information
• Registered office updates
• Accounting records
• Business-specific licences or permissions
• VAT obligations where applicable
• Payroll obligations if the company employs people

Directors remain legally responsible for ensuring the company's records, accounts and filings are properly maintained, even when professional advisers are appointed.

Company registration for foreigners and non-residents

A UK company can be relevant to founders who live outside Britain, but non-resident incorporation needs to be planned carefully.

A foreign founder may potentially own shares and serve as a director because UK company directors do not generally have to live in the UK.

However, several separate issues should be considered:

• Where the founder is tax resident
• Where management decisions are actually made
• Where the business conducts its activities
• Whether UK employees or premises are involved
• Whether the company has UK tax obligations
• Whether immigration permission is required for physical work in the UK
• Whether the proposed business activity requires a licence

Therefore, “UK company registration for foreigners” should not be treated as simply a Companies House filing exercise.

Common mistakes to avoid

Some of the most avoidable problems happen before the application is submitted.

Do not:

• Choose a company name without checking the naming rules and trademarks
• Use an unsuitable registered office
• Treat a virtual address as automatically compliant
• Enter incorrect shareholder information
• Ignore PSC requirements
• Select an unrelated SIC code
• Assume incorporation gives immigration rights
• Forget post-incorporation tax obligations
• Treat the company as a personal bank account
• Ignore annual filing responsibilities

Correct setup creates a much stronger foundation for banking, accounting, taxation and future business expansion.

Why establish a UK company?

The UK remains attractive for founders who want a recognised corporate structure and access to the British market.

A UK private limited company can provide:

• A separate legal identity
• Limited liability for shareholders
• A formal ownership structure
• A recognised corporate vehicle for commercial contracts
• Potential access to investment structures
• A framework for expanding business activities

The value of incorporation, however, depends on the business model. A founder should consider taxation, management location, customers, banking, immigration and compliance before choosing the UK simply because registration itself is straightforward.

For overseas founders, the distinction between company ownership and immigration rights is particularly important. Registering a UK company does not by itself provide permission to live or work in the UK.
