Merger filing redaction is the removal of personal data from a CMA submission. Unlike the mandatory pre-merger filing regimes some other countries operate, notifying a merger to the Competition and Markets Authority under Part 3 of the Enterprise Act 2002 is voluntary — parties choose to notify to get statutory Phase 1 clearance, and the CMA can otherwise call in a completed or anticipated deal on its own initiative. anonym.plus strips names and contacts from the supporting documents on your device, deal data intact.
When this applies
A deal team prepares a voluntary CMA filing with many supporting documents, alongside the Companies House filings the transaction itself triggers. Officer and employee names appear throughout and can be cleared where the CMA allows.

Limitations & cautions
The CMA requires some named officers and contacts in the clear for its substantive assessment. Redact only supporting material the case team agrees does not need them, since the filing's core assessment often does.
Frequently asked questions
Do I have to notify the CMA before completing a merger?
Generally no. Notifying under the Enterprise Act 2002 is voluntary — parties usually do it for the certainty of a Phase 1 clearance, but the CMA can also call in a deal that was never notified. A separate mandatory regime, the National Security and Investment Act 2021, applies only to specified sensitive sectors.
Can I redact the whole filing?
No. The substantive filing needs named officers and contacts for the CMA's assessment. Redaction suits supporting documents where the case team agrees the authority does not need them.
Can I keep one officer consistent across documents?
Yes. A shared label map maps one officer to one alias across the whole set.
