What is the Difference Between a Subsidiary and a Branch in the UK?

Summary

  • A subsidiary is a separate legal entity owned by a parent company, while a branch is simply an extension of the parent company and not legally distinct. 
  • A branch exposes the parent company to full liability for its operations, whereas a subsidiary generally limits liability to the subsidiary itself. 
  • Subsidiaries offer more flexibility and local autonomy but involve more setup and compliance, while branches are simpler but riskier. 
  • This guide explains the difference between subsidiaries and branches for business owners in the UK, prepared by LegalVision, a commercial law firm that specialises in advising clients on corporate structuring.
  • It provides a practical explanation of legal structure, liability, tax and operational considerations when expanding into new markets.

Tips for Businesses

Choose a branch for simplicity and short-term market entry, but be aware of full liability exposure. Use a subsidiary if you want risk protection and local credibility. Assess tax, compliance and long-term strategy carefully before deciding, and seek legal advice to align the structure with your expansion goals.

A subsidiary is a separate legal company owned by a parent business, while a branch is simply an extension of the parent operating in another location or market. For your business, this distinction directly affects liability, tax and operational control, as a branch exposes the parent company to full legal and financial risk, whereas a subsidiary generally limits liability to the new entity and operates under local laws. Choosing the wrong structure can increase risk, compliance burden and cost. This article explains the key differences between a subsidiary and a branch and how each structure affects your business expansion strategy.

What is a Subsidiary?

Subsidiaries are common in the business world, especially for large businesses. To understand how the law defines a subsidiary, suppose there are two separate companies: 123 Ltd and ABC Ltd. 

Imagine that ABC Ltd owns all the shares in 123 Ltd. In this case, the law refers to 123 Ltd as the subsidiary and ABC Ltd as the holding company. This is also the case if any of the following apply:

  • ABC Ltd owns a majority of the shares with voting rights in 123 Ltd; 
  • ABC Ltd has the right to appoint or remove a majority of 123 Ltd’s directors (regardless of if it owns any shares in 123 Ltd); or 
  • ABC Ltd is one of 123 Ltd’s shareholders (among others) and has a private agreement with the other shareholders, giving it a majority of voting rights in ABC Ltd. 

Therefore, if ABC Ltd owned 51% of the voting shares in 123 Ltd, ABC is the holding company, and 123 Ltd is the subsidiary. 

You may hear subsidiaries referred to as undertakings. Where there is at least one subsidiary and a holding company, the law refers to the two companies together as a “group of companies” or simply a group. In practice, many refer to such companies together as a corporate group.

Holding Companies and Parent Companies

As we saw above, a holding company has a strict legal definition. Of course, it is possible for a holding company to itself be a subsidiary of another company. Again, this is quite common for larger businesses. It is not uncommon to see a chain of a dozen companies, with one as the ultimate subsidiary and one as the ultimate holding company. 

We commonly call the holding company “at the top” of the chain, the parent company. However, as with the term “branch”, a parent company does not have a strict legal definition. Although, in most cases, it is obvious which company is the parent company and which are the subsidiaries. 

There are various accounting and tax implications for the parent company in relation to all of its subsidiaries. For instance, a parent company incorporated in the UK has the right to file a single set of accounts for the entire corporate group.

What is the Purpose of Subsidiaries?

Subsidiaries allow a single business to section off different aspects of its operations into separate companies. The main benefit is that despite being part of the same group, each company retains its own limited liability. This means that the holding company is not directly responsible for the subsidiary’s debts and vice versa. Accordingly, this limits the entire business’ risk as a whole. 

Reasons that businesses make use of subsidiaries include:

  • opening in new markets; 
  • raising finance; 
  • separating valuable assets (or pooling them together); 
  • granting security to a bank; and 
  • accounting and tax treatments. 

What is a Branch?

A branch commonly refers to a business with operations in different physical locations and markets. In particular, we commonly see the term branch in reference to businesses with operations in more than one country. For instance, a UK-incorporated company may decide to expand its operations to the Netherlands. When it opens up an outpost in the Netherlands, it may refer to this as its Dutch branch. 

Unlike the term subsidiary, the law does not define the term branch as strictly. That is, there is no hard and fast definition of what constitutes a branch. However, in some cases, particularly concerning retained European Union law and competition law, a branch can refer to an establishment in another country or EU member state, which may have a definite legal meaning. 

In practice, a branch may or may not be a subsidiary. That is, it may not necessarily refer to a distinct legal company. There are many reasons why a branch would be a subsidiary, related mainly to limiting the entire business’s liability. However, at least under UK company law, a company is free to open an office in another location or country without having to incorporate a new company. However, the position might be different in another country or EU member state.

Frequently Asked Questions

What is an overseas company registration requirement?

If your business is ‘established’ in the UK, you must register with the body governing incorporated businesses in England and Wales. For example, if you have an office or premises where your business regularly operates, this will likely constitute an establishment.

How is registration of a foreign business different from incorporation?

If you incorporate a foreign business in the UK, you will create a new legal entity independent of the foreign business. It will have debts and own property. It will be a subsidiary of the foreign business (called a parent company).

Can a subsidiary operate independently from its parent company?

Yes, a subsidiary can operate independently. It has its own legal identity, governance and obligations, even if the parent company owns its shares.

Why might a business choose a branch instead of a subsidiary?

You may choose a branch for centralised control and lower setup costs. It can be useful for testing a new market without the complexity of forming a separate company.
