Limited Company vs Unlimited Company in England and Wales

Table of Contents

When structuring your business as a company, it is important to consider that there are both limited and unlimited companies. Perhaps you intend to incorporate your business into a company but are not sure what the main difference is between a limited company and an unlimited company. This article will explain the key differences between the two legal structures and then highlight the advantages and disadvantages of both. 

Business Structures

There are several different business structures in England and Wales. The most common ones are:

  • sole traders; 
  • general partnerships; 
  • companies; and 
  • limited liability partnerships. 

Likewise, within companies, we can distinguish between two different kinds: 

  • limited companies; and 
  • unlimited companies. 

Further, within limited companies, there are two forms:

  • companies limited by shares; and 
  • companies limited by guarantee.

The vast majority of companies in England and Wales are companies limited by shares. However, some companies exist as unlimited companies, as well as companies limited by guarantee.

All companies have in common the fact that they exist as their own legal personality. This means they can own property, enter into contracts, and sue and be sued. This is why they are considered a type of “incorporated business structure” because the law recognises that they have their own legal “body” (“corpus”). They are legally distinct from their owners.  

Below we examine the key differences between limited and unlimited companies. 

Limited Companies

The overwhelming majority of businesses incorporated as companies in England and Wales are limited companies. Of all limited companies, nearly all of them are those limited by shares. 

Companies limited by guarantee tend to be not-for-profit organisations such as charities, members’ sports clubs, and professional organisations. 

As their names suggest, companies have in common the fact that their owners benefit from the legal principle of “limited liability”. 

All limited companies have an obligation to file accounts and keep Companies House. Companies House is the public body that regulates companies. Likewise, all companies will have their own constitutions, which are formal documents setting out how directors and shareholders will run the company. 

Understanding Limited Liability 

Limited liability refers to the legal concept where the owners of a company will only be partly liable for their company’s debts. 

Therefore, in the event the company ceases to trade, if the company owes other parties money, these parties (or “creditors”) can only recover their debt from the assets of the company. Importantly, creditors cannot usually come after the owners if the company does not have enough money.

The distinction between companies limited by shares and by guarantee is how the principle of limited liability operates. 

Companies Limited by Shares 

The basic principle of a company limited by shares is that a company’s owners (“shareholders” or “members”) will own shares in a company in exchange for providing money to trade and expand. 

Shares are similar to money as their value is linked to the value of the company. They also are a measure of ownership within the company. 

Likewise, company’s share capital will refer to the shares the company has issued to its shareholders. 

For Example

You own a company called FunCo Limited (“FunCo”), along with your business partners Maryanne and Connell. The number of shares issued to each shareholder is:

FunCo ShareholdersNumber of Shares 
You10,000
Maryanne5,000
Connell5,000

We would say FunCo’s issued share capital is 20,000 ordinary shares. This is because 10,000 + 5,000 + 5,000 = 20,000. Likewise, there is only one class of share. 

Limited Liability in a Company Limited by Shares

If you own shares in a company limited by shares, your liability for the company’s debts will not normally exceed the amount of money you have invested in the company. 

Retuning to the example of FunCo:

When you and your partners incorporate FunCo into a company, each person contributed to FunCo a certain amount of money:

FunCo ShareholdersAmount Invested
You£10,000
Maryanne£5,000
Connell£5,000


You will note that the amount invested seems to correspond to the number of shares each person owns. In practice, the number of shares does not always equate to the amount of money you invested for various reasons beyond the scope of this article. 

If FunCo makes a profit, because you own twice as much as your partners, you have entitlements to twice as much.

Suppose, after a year of trading, FunCo has a bad year because of an unexpected pandemic. 

Through no real fault of you and your business partners, you spent all of the company’s cash and could only generate £15,000 in revenue. However, you still owe £5,000 to your suppliers. 

In other words, FunCo is £5,000 in debt to its creditors. If you and your partners decide you do not want to invest any more money in FunCo to rescue it, your creditors will want to get their money back. However, if there is no cash and not enough assets to sell to recover the debt, even though you effectively own 50% of the company, you will not be liable for the company’s debt. 

Your liability to creditors and that of your partners is limited to the value of the shares at the point they were issued to you. 

Liability Limited by Guarantee

At the point a company is incorporated as one limited by guarantee, each of the company’s owners (or “members”) state that if the company runs into financial difficulty, they will pay a certain sum of money to the creditors. This is called the “statement of guarantee”. By law, the members will owe no more than this guaranteed amount. 

In practice, the specified sum is £1. 

Since there are no shares, there is no share capital. Likewise, this makes it considerably more difficult for owners to share in the company’s profits compared to a company limited by shares. 

For the same reason, it is useful for non-profit organisations to incorporate as a company limited by guarantee. The organisation can own property and enter into contracts. However, the owners will not be liable for the company’s debts beyond the amount guaranteed. It also removes the need to transfer shares each time a new owner joins the organisation.

Unlimited Companies 

As you might guess, owners of an unlimited company do not benefit from unlimited liability. This means creditors can pursue each of the members if the company does not have enough assets to cover its liabilities. 

This is offset by the fact that there are fewer requirements for unlimited companies to file accounts and annual reports with Companies House. Its owners also have much more flexibility as far as how to manage the company’s share capital. 

For most businesses, the benefit of limited liability is the main reason the business owners incorporate the business into a company in the first place. 

However, if you run a business where limiting your liability is not a concern, but you do not want to disclose information as you would if you were a limited company, an unlimited company may be relevant. 

Key Takeaways 

The key difference between limited companies and unlimited companies is the extent to which the company’s owners are liable for its debts if the company cannot satisfy its debts. For limited companies, its owners’ liability will either be limited by the value of their shareholding in the company (a company limited by shares) or by an amount guaranteed at the point the company was incorporated (a company limited by guarantee). For unlimited companies, there is no limit to the owners’ liability for the companies debts. Indeed, the vast majority of companies trade using the limited by shares model.

Frequently Asked Questions 

What is a limited company?

There are two kinds of limited companies: those limited by shares and those limited by guarantee. In both cases, the company’s owners will not be responsible for the company’s debts beyond a certain amount. 

What is an unlimited company?

This is a company whose owners will ultimately be responsible for the company’s debts. Since the owners do not benefit from the principle of limited liability, it is not a popular option in practice.
