UK Limited Company Structures Explained: Which One Is Right for You?

When most people think about forming a limited company in the UK, they picture a standard company with shareholders and directors. That covers the majority of businesses, but it's not the only option. There are three distinct structures to choose from, and picking the right one from the start matters.

Here's a clear breakdown of each one.

Key Takeaways

• The three main limited company structures in the UK are: private company limited by shares, company limited by guarantee, and limited liability partnership (LLP).
• Limited by shares is the most common structure and suits most commercial businesses. Shareholders own the company and profits can be distributed as dividends.
• Limited by guarantee has no shares or shareholders. It's designed for nonprofits, charities, and community organisations where profits are reinvested rather than distributed.
• An LLP is a partnership structure with members rather than directors or shareholders. It's taxed differently, with members paying income tax through Self Assessment rather than the company paying Corporation Tax.
• All three structures are separate legal entities with limited liability protection, but they work differently in terms of ownership, profit distribution, and governance.

Private Company Limited by Shares

A private company limited by shares is the most widely used business structure in the UK. It suits most commercial businesses, from sole director startups to multi-shareholder companies.

How It Works

The company is owned by its shareholders. Each shareholder holds a number of shares representing a portion of the company's ownership. The liability of each shareholder is limited to the value of any unpaid shares they hold, which means if the company runs into financial difficulty, personal assets are generally protected.

The company must have at least one director and at least one shareholder. The same person can hold both roles, which is how most small owner-managed companies are set up.

Key Features

• Shareholders can sell or transfer shares to raise capital or change ownership
• Profits can be distributed to shareholders as dividends, which can be tax-efficient compared to taking everything as salary
• The company name is protected on the Companies House register once registered
• The company pays Corporation Tax on its profits
• Suitable for any commercial business looking to trade and grow

Company Limited by Guarantee

A company limited by guarantee has no shares and no shareholders. Instead, it has members who act as guarantors. This structure is built for organisations that exist to serve a purpose rather than to generate personal profit.

How It Works

Guarantors agree to contribute a nominal amount, often just £1, if the company cannot meet its debts and is wound up. Beyond that amount, their personal liability is limited. Profits cannot be distributed to members and must be reinvested into the organisation's activities.

The company must have at least one director and at least one guarantor. One person can hold both roles.

Key Features

• No shares, no dividends, no profit distribution to members
• Profits and surplus income are reinvested into the organisation
• Popular with charities, sports clubs, community groups, membership organisations, and cooperatives
• The structure often makes it easier to apply for charitable status
• Has the same ongoing compliance obligations as other limited companies, including annual accounts and a confirmation statement

Limited Liability Partnership (LLP)

An LLP sits in a different category from the two company types above. It's a partnership structure with its own specific rules around taxation, governance, and membership.

How It Works

An LLP must have at least two designated members. There are no directors, no shareholders, and no shares. Members run the business collectively and the terms of how the LLP operates, including how profits are split and how decisions are made, are set out in an LLP agreement.

The LLP itself does not pay Corporation Tax. Instead, each member pays income tax through Self Assessment on their share of the profits, which makes the tax treatment more similar to a traditional partnership than to a limited company.

Key Features

• Minimum of two designated members required
• No shares or share capital: the LLP cannot sell equity to outside investors
• Each member's liability is limited to what they have agreed to contribute
• Members are taxed individually through Self Assessment rather than the LLP paying Corporation Tax
• An LLP agreement is strongly recommended to set out member responsibilities, profit shares, and what happens if a member leaves
• Popular with professional services firms including law practices, accountancy firms, and consultancies

Comparing the Three Structures

Which Structure Is Right for Your Business?

If you're setting up a commercial business to generate profit and grow, limited by shares is almost certainly the right choice. It's the most flexible, most commonly understood, and most widely supported structure for commercial activity.

If your business exists to serve a community, support a cause, or operate as a membership organisation without distributing profits to its members, limited by guarantee is the structure to look at.

If you're setting up a professional practice with two or more partners who want to share management and profits directly while maintaining limited liability, an LLP is worth considering. It's particularly common in legal, accountancy, and consultancy settings.

If you're unsure which structure fits your plans, speaking to an accountant before registering is the most reliable way to get the right answer for your specific situation.

FAQs

What are the three main limited company structures in the UK?

Private company limited by shares, company limited by guarantee, and limited liability partnership (LLP). Each works differently in terms of ownership, how profits are distributed, and how the company is taxed.

What is the difference between limited by shares and limited by guarantee?

A limited by shares company has shareholders who can receive dividends from profits. A limited by guarantee company has no shares and no dividends. Any profits are reinvested into the organisation. Limited by guarantee is used for nonprofits and community groups; limited by shares is used for commercial businesses.

Does an LLP pay Corporation Tax?

No. An LLP does not pay Corporation Tax. Instead, each member pays income tax individually through Self Assessment on their share of the LLP's profits. This makes the tax treatment different from both limited by shares and limited by guarantee companies.

Can a limited by guarantee company become a charity?

Yes. The limited by guarantee structure is commonly used by organisations that want to apply for charitable status, because it has no share capital and prohibits profit distribution to members. Becoming a charity requires a separate registration with the Charity Commission and is not automatic.

Which company structure is most common in the UK?

Private company limited by shares is by far the most common structure. It suits the widest range of businesses and is the default choice for most commercial startups and small businesses in the UK.

Do all three structures offer limited liability?

Yes. All three are separate legal entities and all provide limited liability protection. In each case, members or shareholders are only liable up to the amount they have agreed to contribute, which means personal assets are generally protected if the company runs into difficulty.
