UK Company House Document API

Retrieves a specific UK Companies House document by its document ID. The document ID is usually pulled from a company report's filing history. Documents come back as PDF and cover annual accounts, confirmation statements, articles of association, certificates of incorporation, change of director notifications and similar filings.
