Company updates and the information which is held on public record

The information that’ll need updating

  • What it does in terms of trading activities.
  • Who controls the company -Persons with Significant Control (PSC).
  • Personal information about the directors in charge and who runs the company.

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

What to consider with regard to the UK Companies House register

The first thing to consider before you set up a new company is which address you would 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. Basically, this is the formal registered address and is where the business will receive its official post.
  • A service address for company officers. This address is where company officers (directors and secretary) are officially contactable.
  • The usual residential address for the directors.
  • A service address for PSCs. This stands for 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 a company officer and PSCs to provide their residential address. In most cases, this’ll be their home address. However, Companies House don’t show the residential address on the public register. 

Choose your registered office and service addresses   

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

  • Your service address; or
  • Registered office.

…then it’ll always show as a part of UK Companies House search on the Companies House register. Importantly, this is also 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 in the case of a lot of accountants.

UK companies also need to keep and maintain statutory records. In most cases, your contractor accountant will do this for you. 

Companies House lookup -further thoughts 

What is the Companies House public register? 

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 regarding certain aspects of its affairs. As a result, various company, and officer details as well as 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 the company. Consequently, this data is then made available to the public on Companies House records.

The collection of Companies House information is often known as the public record or public register (Companies House). Moreover, the 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 using this may need to do a quick Companies House check for some data or be looking to do some business with a company.

More details on the Companies House public register

During a company’s lifetime, Companies House expects you to keep these details up to date at all times. A company can make a change should this be required via the 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 to have some of their personal details show up on the public record.

Companies House retains all records of companies as long as they are active. The records of dissolved companies are also 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 show up if it’s only just been set up therefore give it a few hours or even a day. In addition, UK sole traders aren’t required to register with Companies House therefore you’ll not find their details on there. 

The director’s details which show up on the Companies House public register

If you do a director check (Companies House), the five pieces of information that show up 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.

The director’s address and what you need to bear in mind 

As we mentioned earlier, a director needs to provide two addresses, a service address and a residential address.

A service address is one that a director will receive official mail for the business. Moreover, this address can be the same as the registered office address or elsewhere.

The residential address is a director’s usual home address, and a director will need to inform ROC of this. However, this’ll not 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 use their home address as their service address or the registered office address, it’ll 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.

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 also available for you register a company at Companies House online and this is a quick and fairly straightforward process. However, as we explain earlier, certain 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 also good to know that they don’t have any features that make it easier for search engines to collect or save the Companies House data.
