Companies House is an executive agency of the Department for Business Innovation and Skills (BEIS). 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.

Beta release

The Companies House API and Developer Hub are currently at a beta release. We are going through a process of user engagement to improve the API and documentation.

We have a proposed approach to versioning the API and documentation that is currently being discussed in the Developer Forum. In the meantime, existing resources will remain as they are and can be considered as at 'version 0'.

You can refer to the Developer Forum for ongoing feature and documentation discussions, and announcements about upcoming feature releases.
