Eligibility criteria for a company limited by shares in the UK explained in detail, covering directors, shareholders, registration requirements, legal rules under the Companies Act 2006, and Companies House incorporation procedures in clear, practical terms.

A company limited by shares is the most common form of incorporated business structure in England and Wales. It is governed primarily by the Companies Act 2006 and is designed for businesses where ownership is divided into shares held by shareholders. Each shareholder's liability is generally limited to the amount unpaid on their shares.
Before a company can be incorporated, certain eligibility criteria must be satisfied. These requirements relate to the individuals forming the company, the internal structure, and compliance with UK company law. Understanding these conditions is essential for lawful incorporation and ongoing compliance.
What is a Company Limited by Shares?
A company limited by shares is a separate legal entity from its owners. This means:
- The company can enter contracts in its own name
- It can own property and incur debts
- Shareholders' personal liability is limited to their investment in shares
This structure is commonly used for private limited companies (Ltd) and public limited companies (PLC).
Legal Framework Governing Eligibility
The key legislation governing company formation and eligibility includes:
- Companies Act 2006
- Companies (Registration) Regulations 2008
- Guidance and procedures issued by Companies House
These rules set out who can form a company, how it must be structured, and the minimum requirements for incorporation.
Core Eligibility Criteria
1. Minimum Number of Members
A company limited by shares must have at least:
- One shareholder (member) at incorporation
There is no upper limit on the number of shareholders. A single individual can form and wholly own a private limited company.
2. Directors
A company must appoint at least:
- One director
Key eligibility requirements for directors include:
- Must be at least 16 years old
- Must not be disqualified from acting as a director under the Company Directors Disqualification Act 1986
- Can be a UK resident or non-resident (no nationality restriction)
- Must agree to act and be formally appointed
Public limited companies require at least two directors.
3. Shareholders (Members)
Shareholders are the owners of the company. Eligibility requirements include:
- Can be individuals or corporate entities
- Must subscribe to at least one share during incorporation
- Must agree to the company's share structure as set out in the Articles of Association
There are no residency or nationality restrictions for shareholders.
4. Registered Office Address
Every company must have a registered office in the UK jurisdiction of incorporation:
- England and Wales, Scotland, or Northern Ireland
- Must be a physical address (not solely a PO Box)
- Must be capable of receiving official communications
This address becomes the company's official legal contact point.
5. Company Name Requirements
A proposed company name must meet legal standards:
- Must be unique and not identical or too similar to existing registered names
- Must not contain sensitive or restricted words without permission
- Must end in “Limited” or “Ltd” for private companies (with some exemptions)
Companies House has the authority to reject non-compliant names.
6. Memorandum of Association
At incorporation, subscribers must sign the Memorandum of Association confirming:
- Their intention to form the company
- Agreement to become members and take at least one share each
This document is required for registration but is largely a formal declaration.
7. Articles of Association
The company must adopt Articles of Association, which set out:
- Internal governance rules
- Rights of shareholders
- Appointment and powers of directors
- Procedures for meetings and decision-making
Companies may adopt model articles or bespoke versions.
8. Share Capital Requirements
There is no minimum share capital requirement for private companies limited by shares. However:
- Shares must be issued during or after incorporation
- The company must clearly define its share structure
- Shareholders may hold different classes of shares with different rights
For public limited companies, a minimum issued share capital requirement applies.
9. Persons with Significant Control (PSC)
Companies must identify individuals who have significant control, typically those who:
- Hold more than 25% of shares or voting rights
- Have the right to appoint or remove directors
- Otherwise exercise significant influence or control
PSC details must be recorded and maintained on a statutory register.
10. Legal Capacity and Restrictions
Certain restrictions apply to individuals involved in company formation:
- Undischarged bankrupts may be restricted from acting as directors without court permission
- Disqualified directors cannot participate in management
- Individuals under 16 cannot act as directors
- Companies must not be formed for unlawful purposes
11. Incorporation Process Compliance
To meet eligibility requirements for incorporation, the following must be submitted to Companies House:
- Application for registration (IN01 form or online equivalent)
- Memorandum of Association
- Articles of Association
- Details of directors and shareholders
- Registered office address
- Statement of capital and initial shareholdings
- PSC information
Once accepted, Companies House issues a Certificate of Incorporation, confirming the company's legal existence.
Practical Considerations Before Forming a Company
While eligibility criteria are legally straightforward, practical considerations include:
- Choosing an appropriate share structure for future investment
- Ensuring directors understand statutory duties under the Companies Act 2006
- Confirming compliance with tax registration obligations (Corporation Tax, PAYE if applicable)
- Maintaining statutory registers and filing annual accounts and confirmation statements
Failure to comply with ongoing requirements can result in penalties or strike-off action.
Common Misunderstandings

“Directors must be UK residents”
Incorrect. There is no general residency requirement for directors.
“A company needs significant capital to start”
Incorrect for private companies. There is no minimum capital requirement.

Key Takeaways
To form a company limited by shares in England and Wales, key eligibility requirements include at least one shareholder and one director (aged 16 or over), a registered UK office address, compliant company name, and submission of incorporation documents to Companies House. There are no strict nationality or capital requirements for private companies, but statutory duties, governance rules, and compliance obligations apply from the moment of incorporation.
Understanding these requirements ensures lawful formation and reduces the risk of rejection or future regulatory issues.
