Signal
Companies House ACSP route — filing authority as a control surface
If a counterparty files via an authorised corporate service provider (ACSP), treat filing authority and presenter identity as part of due diligence: it affects what can be filed, by whom, and with what accountability.

How to read this Signal
Evidence → Uncertainty → Trigger → Decision implication
Each Signal separates the sourced change from what remains uncertain, identifies the trigger to watch and states why it matters to a decision.

Key points
What the evidence indicates for the decision.
- →ACSPs become an explicit gate for certain filings; this shifts operational risk from ‘paperwork’ to ‘authorised actions’.
- →Third-party presenters create adjacency risk: weak controls at the presenter can undermine confidence in filings and identity claims.
- →Treat ACSP use as a question to document: who is the ACSP, what is their oversight posture, and what is the audit trail for filings.

Actions
