Why Monitor PSC Changes?

Checking a company's ownership once, at onboarding, tells you who controlled it on that day. Control changes — and when it does, your due diligence is out of date. That is the case for monitoring PSC changes rather than relying on a point-in-time check.

What a PSC change can signal

New controlling party — an acquisition, buyout, or share transfer that changes who you are really dealing with.
PSC removed — a controlling individual stepping back, which can precede restructuring or distress.
Change in control type — a shift from a shareholding to board-appointment control, or a new relevant legal entity in the chain.
Sanctions and PEP exposure — a new owner who introduces sanctions, adverse-media or politically-exposed-person risk.

Who monitors PSC filings

AML and KYC teams keeping customer files current; lenders and credit teams watching borrower ownership; procurement teams screening suppliers; and investors tracking portfolio and counterparty structures.

Manual vs automated

Re-checking Companies House by hand across dozens or hundreds of counterparties is slow and easy to let slip. PSC Monitor watches the companies on your list and emails you when a PSC is added, removed, or changed — turning a periodic manual chore into a continuous, alert-driven control.

Monitor beneficial-ownership changes automatically — get alerted the moment a PSC is added, removed or changed.

Frequently asked questions

How often does company ownership change?

There is no fixed rate — it depends on the company — but ownership can change at any time through share transfers, acquisitions or restructuring, which is why point-in-time checks go stale.

What should I do when a PSC changes?

Re-run your due diligence on the new controlling party: verify identity, screen for sanctions/PEP/adverse-media exposure, and update your KYC file. An alert ensures you act promptly rather than at the next annual review.

Can PSC monitoring be automated?

Yes. PSC Monitor tracks the Companies House PSC filings for companies you choose and alerts you to additions, removals and control changes automatically.
