Explanation of a company limited by shares in UK company law, including meaning, legal structure, shareholder liability, Companies Act 2006 requirements, and key features such as shares, governance, and incorporation rules.

A company limited by shares is the most common type of business structure used in England and Wales for trading businesses, startups, and private enterprises. It is a legal entity incorporated under the Companies Act 2006 where the liability of shareholders is limited to the amount unpaid on their shares.
This structure is central to UK company law and underpins the majority of incorporated businesses registered at Companies House. It provides a clear separation between the company as a legal person and the individuals who own it, enabling structured investment, risk management, and commercial activity.
Meaning of a Company Limited by Shares
A company limited by shares is a type of incorporated business where:
- The company has its own separate legal identity
- Ownership is divided into shares
- Shareholders own the company through their shareholdings
- Shareholders' liability is limited to their investment in shares
In legal terms, this means the company itself is responsible for its debts and obligations, not the individual shareholders, except to the extent of any unpaid share capital.
This structure is defined and governed by the Companies Act 2006 and is the default form used for most private limited companies (LTDs) in the UK.
Separate Legal Personality
A key feature of a company limited by shares is separate legal personality. This principle means:
- The company exists independently of its owners
- It can enter contracts in its own name
- It can own assets and incur liabilities
- It can sue and be sued in its own right
This principle was firmly established in UK law in Salomon v A Salomon & Co Ltd [1897], which remains a cornerstone of company law.
The practical effect is that shareholders are not personally responsible for the company's debts.
Core Features of a Company Limited by Shares
1. Limited liability of shareholders
Shareholders are only liable up to the value of their shares. If shares are fully paid, they generally have no further financial liability.
This protects personal assets from business risks, subject to exceptions such as personal guarantees or misconduct.
2. Share-based ownership structure
Ownership is divided into shares, which represent:
- A proportion of ownership in the company
- Voting rights (depending on share class)
- Rights to dividends if declared
- Rights to capital on winding up
Shares can be transferred, sold, or issued to new investors, allowing flexible ownership structures.
3. Issued share capital
At incorporation, the company issues shares to its founders or subscribers. This creates the issued share capital, which is recorded at Companies House and reflected in the statement of capital.
The nominal value of shares (often £1 or £0.01) determines the legal minimum capital structure.
4. Separate company assets and liabilities
All assets and liabilities belong to the company, not the shareholders. This includes:
- Business property
- Bank accounts
- Contracts and debts
Shareholders do not own company assets directly; they own shares representing their interest in the company.
5. Legal governance structure
A company limited by shares is governed by:
- The Companies Act 2006
- The company's articles of association
- Directors' statutory duties
- Shareholder resolutions
Directors manage day-to-day operations, while shareholders retain ultimate control over key decisions such as appointing directors or approving major structural changes.
6. Profit distribution through dividends
Profits are not automatically distributed. Instead, they may be paid as dividends, which are:
- Declared by directors
- Paid to shareholders in proportion to shareholdings (unless otherwise specified in share rights)
- Subject to available distributable profits
7. Transferability of shares
Shares in a company limited by shares can generally be transferred, subject to:
- Restrictions in the articles of association
- Shareholder agreements
- Pre-emption rights (rights of first refusal)
This allows ownership to change without affecting the legal existence of the company.
Types of Companies Limited by Shares
Private limited company (Ltd)
The most common structure in the UK. Features include:
- Shares not offered to the public
- Restrictions on share transfers

Incorporation and Legal Requirements
To form a company limited by shares, founders must register with Companies House and provide:
- Company name
- Registered office address
- Details of directors
- Statement of capital and shareholdings
- Articles of association
- PSC (Persons with Significant Control) information
- SIC code(s)
Once registered, the company becomes a separate legal entity and can begin trading.
Advantages of a Company Limited by Shares
1. Limited financial risk
Shareholders' liability is limited, reducing personal exposure.
2. Investment flexibility
The structure allows external investment through share issuance.
3. Business credibility
Incorporation often improves trust with banks, suppliers, and clients.
4. Perpetual succession
The company continues to exist regardless of changes in ownership or directors.
5. Tax efficiency
Companies are subject to corporation tax, which may be advantageous compared to personal taxation in some cases.
Risks and Legal Considerations
1. Compliance obligations
Companies must meet ongoing legal requirements, including filings and accounting obligations.
2. Director liability
Directors may still be personally liable for misconduct, wrongful trading, or breach of duties.
3. Loss of investment
Shareholders may lose their entire investment if the company becomes insolvent.
4. Complex governance
Companies with multiple shareholders may face disputes over control and decision-making.

“Limited liability removes all risk”
Incorrect. Liability is limited, but not eliminated, particularly where guarantees or misconduct exist.
“All companies can sell shares publicly”
Only public limited companies (PLCs) can offer shares to the public.

Key Takeaways
A company limited by shares is the standard UK business structure where ownership is divided into shares and shareholder liability is limited to the value of those shares. It operates as a separate legal entity, allowing it to own assets, enter contracts, and incur liabilities independently of its owners.
