Question 1

What is a person with significant control (PSC)?

Accepted Answer

A person with significant control (PSC) is an individual or legal entity that owns more than 25% of a UK company's shares or voting rights, has the right to appoint or remove a majority of its directors, or otherwise exercises significant influence or control. UK companies are legally required to identify their PSCs and file the information with Companies House under Part 21A of the Companies Act 2006. The PSC register is published by Companies House and re-indexed by OpenRegistry by Sophymarine.

Question 2

How many UK companies is Isabelle Yu-Ying Cook recorded as controlling?

Accepted Answer

Companies House records Isabelle Yu-Ying Cook as a person with significant control over 6 UK companies (4 active and 2 ceased appointments). OpenRegistry's PSC name index groups every appointment under one canonical slug (isabelle-yu-ying-cook); the full list with company numbers and click-through to each company's profile is at https://openregistry.sophymarine.com/uk-companies/psc/isabelle-yu-ying-cook.

Question 3

How do I see the directors, shareholders and filings of SMIS PROPERTY INVESTMENT LIMITED?

Accepted Answer

Each company on this page links to its OpenRegistry profile. From the company profile you can drill into directors and officer history (/officers), shareholders and beneficial owners (/shareholders), accounts and financial filings (/financials) and the full Companies House filing history (/filings). The live profile for SMIS PROPERTY INVESTMENT LIMITED is at https://openregistry.sophymarine.com/company/gb/08690025.

Question 4

Is everyone listed on this page the same person?

Accepted Answer

OpenRegistry groups PSCs by the slugged form of their name (isabelle-yu-ying-cook). Companies House does not assign a stable identifier to individual PSCs, so this name index will collide where two unrelated people share the same name. Use date of birth (month + year only, published by Companies House), nationality, country of residence and the underlying company profiles to distinguish individuals. Corporate PSCs (RLEs) carry a registration number visible on each company profile.

Question 5

How does OpenRegistry source Isabelle Yu-Ying Cook's PSC record?

Accepted Answer

OpenRegistry by Sophymarine resolves Isabelle Yu-Ying Cook from the Companies House Persons with Significant Control bulk feed (https://openregistry.sophymarine.com's PSC name index slug isabelle-yu-ying-cook; OpenRegistry canonical ID GB-PSC-isabelle-yu-ying-cook). The official record for each company is at https://find-and-update.company-information.service.gov.uk/company/<number>/persons-with-significant-control. Programmatic access via MCP at https://openregistry.sophymarine.com/mcp.
