Companies House is an executive agency of the Department for Business and Trade. Our main functions are: to incorporate and dissolve limited companies; examine and store company information delivered under the Companies Act and related legislation; and make this information available to the public.

The Companies House API lets you retrieve information about limited companies (and other companies that fall within the Companies Act 2006). The data returned is live and real-time, and is simple to use and understand.

Before you start

If you are new to the Companies House API, take a look at the get started guide, which has resources and information to help you.

In the Developer Forum, you can also discuss the API, find help and provide feedback.
