Registered Agent Services: The UK Perspective

In UK company law, there is no statutory position of ‘registered agent’ and no official meaning of the term ‘registered agent services’. The term ‘registered agent’ actually originates from the United States, where LLCs and corporations are required to have an official address where legal documents and official correspondence can be sent. The US-registered agent then forwards any documents received to the LLC or corporation by email or post in a timely manner. In this respect, the legal requirements for companies differ between the US and the UK. Rather than being required to nominate a registered agent, all UK companies must have and maintain a registered office address in England and Wales, Scotland or Northern Ireland for service of official documents.

The term ‘registered agent services’, on the other hand, is commonly used by British business service providers such as formation agents offering registered office, mail handling and company-secretarial services.

In this article, we will explain the UK perspective on the equivalent of US registered agents. In particular, we will explain whether UK companies are required to have a registered agent and the differences between registered agents, UK company formation agents, registered agent services, and Authorised Corporate Service Providers (ACSPs).

Are UK companies required to have a registered agent?

Companies in the UK are not legally required to have a designated registered agent in the same way that LLCs must do so in the United States. The reason for the confusion tends to originate from the common use of the term ‘registered agent services’ by British business service providers offering registered office, mail handling and company-secretarial services. While this term is often used, it has no legal meaning in the UK and the Companies Act 2006 has no such designation. 

Where must company legal documents and official correspondence be sent in the UK?

Companies in the UK are required by section 86 of the Companies Act 2006 to have a registered office address in England and Wales, Scotland or Northern Ireland for the service of official documents. It states, “A company must at all times have a registered office to which all communications and notices may be addressed”. Section 87(1) specifies that “The registered office of a company must be situated in England and Wales, in Scotland or in Northern Ireland”. 

Alternatively, many businesses prefer to use the services of a company formation agent that provides a registered office address service, very much in the same way as a US registered agent. 

What is a registered office address in the UK?

All companies in the UK are legally required to provide a physical registered office address when establishing a limited company with the official registrar of companies, Companies House. A registered office is the official legal address of a company that receives any statutory mail and legal documents. Registered office addresses are also used as a location where any statutory registers are stored, maintained, and made available for public inspection (unless they have a designated ‘Single Alternative Inspection Location – SAIL – address as an alternative). 

What are the requirements for a UK-registered office address?

In order to register a company registered office address in the UK, the following requirements must be met:

• It must be a physical location in the UK (i.e. not a PO box)
• It must be in the country where the company is registered
• The appropriate individuals must be made aware of any post addressed and delivered to the company, and
• The sender should be able to receive a receipt of delivery 

If you use a third-party service provider registered office address (for example, the address of a company formation agent or accountant), the address must still meet all of the above requirements. 

It is important to remember that the registered company address you provide will be made public. If you want to keep your address private, it is recommended to use the services of a company formation agent that will receive your mail and ensure it is automatically and promptly forwarded to you to be dealt with.

What are registered agent services?

Registered agent services in the UK are business services provided by third parties such as company formation agents. Such services may include:

• Provision of a compliant registered office address
• Receipt and forwarding of official and other business mail
• Maintenance or protection of statutory registers
• Filing reminders and submissions to Companies House, and 
• Optional nominee or compliance support.

What is a company formation agent in the UK?

Company formation agents in the UK handle all aspects of company registration and incorporation with Companies House for limited companies, Limited Liability Partnerships, and Companies Limited by Guarantee. Company formation agents such as Uniwide Formations offer a range of incorporation packages to cater for different needs. 

One of the main reasons that business people and entrepreneurs opt to use our company formation services is that we will check your application before it is submitted to Companies House. This avoids the chance of your company registration application being rejected, saving both time and money. 

What is an authorised corporate service provider (ACSP) in the UK?

Authorised corporate service providers (ACSPs) are typically company formation agents, Solicitors and accountants who act as an intermediary between Companies House and limited companies, LLPs, and limited partnerships. ACSPs liaise with Companies House on behalf of incorporated businesses to:

• Verifying the identity of directors and persons with significant control (PSCs)
• File documents (e.g. annual confirmation statements) (from Spring 2026)
• Maintain identity verification documents for inspection, and
• Liaise with Companies House in relation to identity checks

ACSPs were introduced with the Economic Crime and Corporate Transparency Act 2023 (ECCTA) in order to make it harder to register fake companies and individuals with Companies House and reduce the prevalence of money laundering in the UK. The change was also introduced to ensure the proper identity verification of company directors, PSCs and beneficial owners. 

Who can be an ACSP in the UK?

An ACSP can be a business (e.g. limited company or partnership) or an individual who handles the identity verification and filing of documents for companies. There are strict criteria that must be met in order for an entity to gain approval as an ACSP. Applicants must be supervised by a UK Anti-Money Laundering (AML) supervisory body.

Why do UK companies still need only a valid registered office?

UK companies only need a valid registered office address rather than a registered agent as is mandated in the US because UK company law places the responsibility for legal compliance and official correspondence directly on the company itself, not on a third party. Ultimately, it is the responsibility of the company and its officers (e.g. directors and secretaries) to maintain company records, file accounts and confirmation statements, and receive legal documents. The law in the UK enables businesses to make the choice between using their own registered office address or that of a third-party agent. 

Final words

We hope this article has given you a better understanding of the UK’s perspective on registered agent services. Making the adjustment from how business is done in the US and UK is vital for those planning to expand or move their operations here. While there are some similarities, there are also some key differences between US registered agents and UK company formation agents and authorised corporate service providers (ACSPs). If you plan to establish a business in the UK, it is important to have a strong grasp of company law and your obligations when it comes to incorporation, annual filings and meeting your regulatory obligations.
