PSC01 is the filing code people usually see when an individual person with significant control is put onto the register at Companies House. In practical terms, it is one of the clearest public signals that the ownership or control picture around a company may have changed.
That makes PSC01 more than a technical filing label. If your team monitors beneficial ownership, governance exposure, or verification-related follow-up, PSC01 is the kind of event that deserves a proper review rather than a quick skim.
What does PSC01 mean?
PSC01 means a filing was made to put an individual person with significant control onto the register. In plain language, the company has recorded a new individual PSC notice on the public record.
That makes PSC01 a different kind of signal from director filings such as AP01, TM01, or CH01. It belongs to the ownership and control layer of the record rather than the board-composition layer.
What PSC01 can and cannot tell you from the code alone
PSC01 tells you that an individual PSC notice was filed, which is already meaningful because it points to a control-related event. It does not, by itself, explain the whole ownership chain or tell you everything that changed around the company.
In practice, PSC01 is best treated as a prompt to inspect the live PSC section, the nature-of-control wording, and any nearby filings that help explain the broader position.
Why PSC01 matters for ownership and governance monitoring
PSC changes matter because they affect the control picture your team may rely on for risk review, governance context, onboarding checks, or client reporting. A PSC01 is therefore one of the clearest filing-history signals that ownership review may be needed.
It can also matter alongside director changes or confirmation-statement activity, because a company can go through several governance updates around the same period.
What to check after you see PSC01
Once PSC01 appears, the practical move is to read the live PSC record and surrounding context rather than relying on the code alone.
Open the current PSC section Confirm that the individual now appears on the live record and read the control wording attached to that entry.
Compare with your previous ownership view If your team tracks control or beneficial ownership manually, make sure the new public position is reflected properly.
Check nearby filings Look for confirmation-statement, director, or address filings near the same period that may help explain the wider company update.
Decide whether the change needs active follow-up If the PSC event matters to risk, reporting, or compliance workflow, someone should own the review instead of leaving it as a passive watchlist change.

Common questions
Does PSC01 mean a PSC was added to the register?
Yes. In practical terms, PSC01 points to an individual person with significant control being put onto the register.
Is PSC01 the same as a director appointment filing?
No. PSC01 is a control-related filing rather than a board-appointment filing.
Does PSC01 tell me the full ownership picture by itself?
No. It tells you an individual PSC notice was filed, but you still need the live PSC section and surrounding record to understand the wider context properly.
Can Entity Watch file PSC01 for me?
No. Entity Watch is not a filing agent and does not submit Companies House forms for you. It is a monitoring and workflow layer that helps teams understand what changed, what deadline is next, and where to follow up.
