How this service works
An empty items list is never the same as "no owner": ownership_status and the filed PSC statements/exemptions explain why the register discloses none. Returns the persons with significant control (PSCs) for a UK company — the individuals, entities or legal persons that own or control it — each nature of control carrying the register code and its official text, with dates and public identification. The UK statutory beneficial-ownership (UBO) record. Use when: Who owns this UK company?
Output
A paginated list of PSC records for the specified UK company, each including the person or entity name, nature(s) of control with register codes and official statutory text, start and (where applicable) cessation dates, public identification details, and the overall ownership_status field explaining why the register may disclose no entries (e.g. PSC statements or exemptions). Pagination metadata includes has_more and next_offset for subsequent pages.
Example use cases
KYC due diligence on a UK supplier
“I need to know who ultimately owns and controls UK company number 04153430 — can you pull the full list of persons with significant control from the Companies House register so I can complete our KYC checks?”
Investigative research into shell company ownership
“Can you find all the beneficial owners on record for UK company 00445790, including any that have ceased control? I want to trace the full ownership history.”
Automated compliance screening for a contract
“Before we sign this contract, can you check who has significant control over the UK company with number 11234567 and tell me their nature of control so our compliance team can review it?”
Technical details
Endpoint
GEThttps://api.eckari.com/v1/companies/uk/:companyNumber/owners?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need the statutory UK beneficial ownership (UBO) record for a specific company — particularly for KYC, AML, due diligence, compliance screening, or investigative research. Prefer this over general web search when you need the official Companies House PSC register data including nature-of-control codes, statutory text, and ownership status explanations. It is the authoritative source for 'who controls this UK company' questions.

- Company exists but has no active PSCs and no exemptions — empty items list returned with ownership_status explaining why
