Why corporate ownership structure matters
Beneficial ownership, ultimate parent companies, and subsidiary networks matter for due diligence, KYB checks, M&A research, and understanding who you're really doing business with. Companies House publishes this data, but piecing together a full structure manually — checking PSC filings, cross-referencing subsidiary registrations — is slow. Company Watcher maps it automatically.
How the ownership tree works
Automated corporate family tree discovery powered by public Companies House PSC records.
Search any UK company
Search any UK company by name or official registration number to initialize the lookup.
Auto-map corporate tree
We automatically discover its parent companies and subsidiaries via Persons with Significant Control (PSC) records.
Track family changes
Track the whole family — or just the parts you care about — and get alerted when the structure changes.
Built for due diligence and compliance use
Whether you're doing supplier due diligence, KYB checks on a new customer, or M&A research on an acquisition target, understanding the full corporate structure — not just the entity in front of you — is essential. Company Watcher's ownership tree surfaces parent companies, subsidiaries, and PSC changes across the whole family, sourced directly from the Companies House public register.
