Using the web portal, you can save search results for companies meeting the desired criteria as lists. These lists are updated automatically as new companies that meet the criteria are discovered.

You can then retrieve the list data programmatically using the /GetListData endpoint. This data includes the key financials displayed on the search results page.

An (optional) email notification is sent whenever a new company is added to the list or when data for an existing company is updated at Companies House.

If you wish to perform the initial search programmatically instead of using the web portal, access to this API endpoint and the new request/response formats is available upon request.
