What is Companies House?

Companies house is a government department that incorporates and regulates companies in the UK.

The main responsibilities undertaken by companies house include the incorporation and dissolving of limited companies and general management of company information for both government and public use.

With more than 4 million companies usually registered at any one time around 1000 staff based around the UK are needed to carry out company house processes.

Companies house makes it easy to find most of the information people need online with services like companies house search to find out more about a company and the company name availability checker for new incorporations.

Companies House search

The companies house search service is based online and gives individuals and businesses free access to the information they hold about limited companies and limited liability partnerships.

All incorporated companies need to legally provide companies house with financial and personal information about the company directors.

This data is made available to the public partly to help encourage transparency and best business practices in the UK.

It is commonly used by businesses to check the particulars of a company of interest who they may want to work with or investors as part of their research before buying shares in a company.

Some of the company information available includes:

  • Company registered address.
  • Company incorporation date.
  • Company director facts.
  • Insolvency information.
  • Micro company accounts.
  • Company confirmation statement.

A free email alert can be set up which tells you when a company updates its details like a change of director.

You don’t need to register or provide any personal info to use the companies house search service and you can use it as many times as you want.
