Beneficial ownership, explained.
Compliance teams use two overlapping terms for the real owners of a company: PSC (Person with Significant Control) and UBO (Ultimate Beneficial Owner). They describe the same idea from different frameworks.
"Person with Significant Control" is the specific term used in UK company law and on the Companies House register. It is defined by the five statutory conditions, with the headline test being ownership or control of more than 25% of shares or voting rights.
"Ultimate Beneficial Owner" is the term used in anti-money-laundering regulation and international standards. Under the Money Laundering Regulations, a beneficial owner is typically an individual who ultimately owns or controls more than 25% of an entity — closely aligned with the PSC threshold.
For most UK companies, the PSCs recorded at Companies House are the same people you would identify as UBOs in a KYC file. The PSC register is therefore a practical starting point for UBO verification — but AML rules require you to verify beneficial ownership independently, not rely on the register alone, and to keep it under review.
UBO information is only useful if it is current. Because PSC filings change as ownership changes, monitoring them is an efficient way to keep UBO records up to date across a portfolio of counterparties.

It is a strong starting point, but AML rules require you to verify beneficial ownership independently and keep it under review rather than relying solely on the register.
Generally more than 25% ownership or control of an entity, which aligns with the UK PSC threshold.
