Comparing the Different Types of Limited Companies in the UK

Choosing the right legal structure is one of the first decisions you make when setting up a business in the UK. While most small businesses opt for a private company limited by shares, Companies House recognises several different company structures, each designed for different ownership models, objectives and levels of risk.

The main UK company types are private companies limited by shares, private companies limited by guarantee, private unlimited companies and public limited companies. LLPs are a separate incorporated structure that combines partnership-style operation with limited liability. The right structure depends on factors such as whether you intend to distribute profits, who owns the business, how you want to raise finance and the level of liability protection you need.

Exploring the Main Types of Limited Companies in the UK

1. Private Company Limited by Shares (Ltd)

A private company limited by shares is the standard structure used by most commercial businesses in the UK.

The company has shareholders who own shares in the business. Those shares can carry voting, dividend and other rights. Shareholders’ liability is generally limited to any amount unpaid on their shares. A private company cannot offer its shares to the general public.

A company limited by shares can have just one shareholder and one director, so it works equally well for a solo owner managed business and for a business with multiple owners. The same person can be both the sole shareholder and sole director.

This structure is commonly used by businesses that intend to generate profits and potentially distribute them to shareholders through dividends.

Best suited to:  consultants, freelancers, start-ups and most commercial small businesses.

Key advantages:

• Limited liability for shareholders.
• Straightforward ownership through shares.
• Profits can potentially be distributed as dividends.
• Suitable for bringing in additional shareholders or investors.
• One person can own and operate the company.

For most owner-managed businesses considering incorporation, this is the type of private limited company they will be considering.

2. Private Company Limited by Guarantee

A private company limited by guarantee does not have shareholders or share capital in the traditional sense. Instead, it has members known as guarantors.

Each guarantor agrees to contribute a specified amount if the company is wound up and cannot meet its liabilities. The guarantee is usually a relatively small amount, depending on the organisation’s constitution.

This structure is commonly used by organisations that are not established primarily to distribute profits to owners, including clubs, community organisations and some charities.

Instead of paying profits to shareholders, profits are generally retained and used to support the organisation’s objectives.

Best suited to: non-profit organisations, community groups, clubs and certain charitable organisations.

It is important to note that simply being limited by guarantee does not automatically make an organisation a registered charity or give it special tax treatment. Those are separate matters.

3. Public Limited Company (PLC)

A public limited company, or PLC, is a company limited by shares that is permitted to offer its shares to the general public. Its shares may also be quoted on a stock exchange, although becoming a PLC does not automatically mean that the company is listed.

PLCs are subject to more demanding legal, financial and governance requirements than typical private companies. They are generally used by larger businesses seeking access to substantial external investment rather than by small owner-managed businesses.

A PLC must have at least two directors and a company secretary, and it must satisfy statutory share capital requirements before it can commence business as a public company.

The minimum allotted share capital is generally £50,000, or the prescribed euro equivalent, with at least one-quarter of the nominal value of each share and the whole of any premium paid up.

Best suited to: larger businesses seeking to raise significant capital from public investors.

4. Private Unlimited Company

An unlimited company is different from the limited structures above because its members do not have a statutory limit on their liability.

If the company cannot meet its debts, members can potentially be required to contribute beyond the amount they originally invested. Only private unlimited companies can be formed under the Companies Act framework.

Unlimited companies are relatively uncommon. They may appeal in particular circumstances where the owners want the flexibility of a corporate structure without limited member liability, but the exposure to potentially unlimited liability makes this a structure that requires careful consideration.

There are also differences in filing and disclosure requirements compared with limited companies, so professional advice is sensible before choosing this structure.

Best suited to: specific business situations where the owners understand and deliberately accept unlimited liability.

5. Limited Liability Partnership (LLP)

A Limited Liability Partnership (LLP) is not technically a type of limited company. It is a separate incorporated business structure that combines features of a traditional partnership with limited liability.

An LLP has two or more members, who can be individuals or companies. Unlike shareholders in a company limited by shares, LLP members generally participate in the business as partners and share its profits according to their agreement.

The LLP itself has a separate legal identity, while members generally benefit from limited liability. LLPs must also prepare and file accounts with Companies House, subject to the applicable exemptions and filing rules.

Best suited to: professional practices and businesses where several owners want a partnership-style structure with limited liability, such as certain legal, accountancy, architectural and consultancy practices.

Summary Comparison: Which Company Structure Should You Choose?

Quick Decision Guide

Choose a private company limited by shares if:

You are running a normal profit-making business and want limited liability, straightforward ownership and the ability to distribute profits to shareholders.

Consider a company limited by guarantee if:

Your organisation has a social, community or non-profit purpose and does not need conventional shareholders.

Consider a PLC if:

Your business is sufficiently large and you need the ability to raise capital by offering shares to the public.

Consider an unlimited company if:

You have a specific reason for accepting unlimited member liability and have taken appropriate professional advice.

Consider an LLP if:

You have two or more business owners and want the operational flexibility of a partnership combined with a corporate legal identity and limited liability.

Getting the Right Structure and Accounting Support

Choosing between the different types of limited companies in the UK is not simply an administrative decision. Your structure can affect ownership, liability, how profits are distributed, reporting requirements and the way your business is taxed.

For most owner-managed businesses, a private company limited by shares will be the natural structure to investigate first. However, businesses with non-profit objectives, multiple professional owners, public investment ambitions or unusual liability considerations may need a different arrangement.

Whichever structure you choose, maintaining accurate records and meeting your company’s accounting and filing obligations remains essential. Directors and other business owners are responsible for ensuring that the appropriate statutory requirements are met.
