TM01 is the filing code usually seen when a director appointment has been terminated and the change is filed at Companies House. In practice, TM01 is one of the clearest board-change signals in filing history because it tells you a director is no longer in that active appointment position.
What TM01 does not do is explain the whole story by itself. The code tells you the appointment ended, but it does not give you the full commercial or governance reason without checking the wider company context.
What does TM01 mean?
TM01 means a termination of director appointment filing was made at Companies House. In plain language, it points to the end of that director's appointment on the public register.
For filing-history readers, TM01 is the inverse of AP01. One points to a director coming in, the other points to a director stepping out of the active appointment position.
What TM01 does not tell you from the code alone
TM01 tells you that the appointment ended. It does not, by itself, explain the boardroom story behind that change. If you want the business meaning, you still need the live officer list, nearby filings, and the broader context around the company.
That distinction matters because not every TM01 is a risk event, but every TM01 is a governance event worth reading properly.
Why TM01 matters for governance monitoring
Director exits can affect control, signing authority, board capacity, and the people your team expects to see on the record going forward. That makes TM01 a high-signal filing code for anyone monitoring client portfolios or company governance changes.
It can also matter for verification workflow because the current active-officer picture may now be different from the view your team was working from before the filing landed.
What to check after you see TM01
The practical move after a TM01 is to confirm who remains active, whether other officer changes landed near the same time, and whether the company record now looks materially different.
Recheck the active directors Make sure the current officer list reflects the board position you expect after the termination filing.
Look for nearby AP01 or other officer filings A termination may sit next to a replacement appointment or other governance changes in the same period.
Check the timing against company deadlines Board exits often matter more when they happen near a confirmation statement or another operational deadline.
Record the change in the workflow, not just the watchlist If a board change affects responsibility, ownership, or control evidence, someone should actively review it rather than letting the filing sit untriaged.

Common questions
Does TM01 mean a director left the board?
It means a termination of director appointment filing was made. In practical terms, it signals that the appointment ended on the public record.
Does TM01 tell me why the director left?
No. The code itself does not explain the wider reason. You need the broader company context if that question matters for your review.
Is TM01 automatically a red flag?
Not automatically, but it is a high-signal governance change. It should prompt a review of the current officer position and any related filings.
Can Entity Watch file TM01 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.
