  • Who controls the company -Persons with Significant Control (PSC).
  • Personal information about the directors in charge and who runs the company.

good accountant will file official documents for you as a limited company contractor, although this is officially part of a director’s duties.

What should you consider regarding the UK Companies House register?

The first thing to consider before you set up a new company is which address you’d like to use for your new business.

What’s more, when you incorporate a new business, company law, as stated in the Companies Act 2006, will require you to provide an address for each of these:

  • The registered office address. This is the formal registered address where the business will receive its official post.
  • A service address for company officers. This is where company officers (directors and secretaries) are officially contactable.
  • The usual residential address for the directors.
  • A service address for PSCs. This stands for a Person with Significant Control. Once again, this address is where PSCs are officially contactable.
  • The usual residential address’ for PSCs.
  • The usual residential address of the initial subscribers (shareholders).

As mentioned above, the Companies Act requires company officers and PSCs to provide their residential addresses. In most cases, this will be their home address. However, Companies House doesn’t show the residential address on the public register. 

How should you choose your registered office & service addresses?

When setting up your company, if you choose to use your home address as either:

  • Your service address; or
  • Registered office.

…then it’ll always show up in a UK Companies House search on the official register. Importantly, this is the case, even if you change it later. To sum up, you should carefully think about this before setting up your new company.

Most company formation agents, solicitors, and accountants often offer an address hosting service for a small fee or no fee for many accountants.

UK companies must keep and maintain statutory records. In most cases, your contractor accountant will look after this for you. 

Further thoughts on Companies House lookup 

What is the official public register at Companies House? 

ROC’s public record is a Companies House list of company names in the UK. For the benefit of limited liability status, a company must be open and transparent about certain aspects of its affairs. As a result, various company and officer details and the filing history are shown under each company profile.

Therefore, when you set up a new company, ROC will review and register specific information about it. This data is then available to the public on Companies House records.

The collection of Companies House information is often known as the public record or public register. Moreover, the official Companies House details for each company are available online for the public and businesses to look up a company or do a Companies House person search. A person may use this to do a quick Companies House check for data or want to do business with a company.

Further details regarding the public register

Companies House expects you to keep these details updated throughout a company’s lifetime. Should this be required, a company can make a change via the official Companies House online filing service. Such a change could include a change of address or company official.

To sum up, a person who becomes a director or officer of a company must be ready for basic personal details to appear on the public record.

Companies House retains all company records if they’re active. The records of dissolved companies are retained for 20 years before they are transferred to the Public Records Office at The National Archives (TNA). This includes all the information related to company directors or its officers. Therefore, once you’ve closed your company, Companies House will keep the details of your dissolved company for 20 years.

Why is a company not showing under Companies House? 

All UK companies are required to register on Companies House. This means each company will display on their official index. A company may not yet show up if it’s just been registered; therefore, give it a few hours or even a day. In addition, UK sole traders aren’t required to register with Companies House; thus, you’ll not find their details there. 

Which director’s details are shown on the official public register?

If you do a director check (Companies House), the five pieces of personal information which show up as part of a Companies House lookup on the public record for all UK directors are:

  • The name of the director.
  • Their service address.
  • One’s nationality.
  • Their occupation.
  • The month and year of their date of birth.

The details above are also shown online for PSCs, except for their nationality and occupation.

What to consider for your director’s address?

As mentioned earlier, a director must provide two addresses:

  • A service address; and
  • A residential address.

A service address is where a director will receive official mail for the business. It can be the same as the registered office address or elsewhere.

The residential address is a director’s usual home address, and a director must inform ROC of this. However, this won’t appear on the public record for all to see, as Companies House keeps this on a private register. However, ROC may provide home address details to credit reference agencies and certain public bodies if there’s a requirement to do so.

Therefore, if a director or PSC uses their home address as their service or registered office address, it will appear on the UK company register.

To sum up, if you don’t want your home address to show on the public record, you should use a different address from the outset. Indeed, your chosen address will then show as your registered office and director’s service address. The address you select could be that of your accountant, a service provider, or perhaps somewhere else.

Final thoughts 

It’s good to know the UK Public Register is open and available for anyone who wants to do a Companies House search (UK). UK company owners will use Companies House online filing to keep their business details up to date. This is an official requirement, and an update should be made when a change occurs.

The official register and list of limited companies (UK) allow you to do a quick Companies House lookup whenever needed. Basically, ROC can’t prevent any third parties from being able to find specific details on the UK company register. What’s more, the online website is available for you to register a company at Companies House online, and this is a quick and straightforward process. However, as we explained earlier, specific information for all UK companies is part of the public record. Therefore, if you want to hide your home address, please consider our advice above.

Finally, ROC doesn’t actively index information from its search services. Furthermore, it’s good to know they don’t have any features which make it easier for search engines to collect or save Companies House data.
