Ongoing monitoring, without a manual re-check cycle
UK Money Laundering Regulations require ongoing monitoring of business relationships, not just a check at onboarding. RegisterWire alerts you the moment a client company changes — new filings, director and PSC changes, insolvency events — delivered automatically by webhook or poll.
Free tier: up to 10 companies. Test instantly against the real pipeline with the simulate endpoint.
Onboarding checks aren't the whole job
The UK's Money Laundering Regulations require regulated firms to keep customer due diligence up to date throughout a business relationship, not only at the start of it. A client's ownership, control, or officers can change well before your next scheduled review — and a periodic manual check against Companies House is exactly the kind of process that's easy to fall behind on as a client book grows.
Companies House publishes every one of these changes, in real time, for free — the catch is that watching even a handful of clients means holding a permanent connection open to a feed covering every company on the register, and building your own filtering, reconnect, and backoff logic before you see a single useful alert.
This page is general information, not legal or compliance advice — whether and how ongoing monitoring applies to your firm is a matter for your own compliance function.

Questions from compliance & AML teams
Does this replace our KYC policy or CDD process?
No. RegisterWire is a monitoring signal, not a compliance programme — it tells you the moment a change happens on a client you're watching. What that means for your own due diligence process is your call.
Is RegisterWire itself a regulated AML service?
No. We relay public Companies House data faster and more conveniently than building the integration yourself. This isn't legal or compliance advice, and using it doesn't by itself satisfy any regulatory obligation.
Which change types should we watch?
Most subscribers watch PSC changes, director and officer changes, control statements, and insolvency events — all available individually, so monitoring can match your own risk-based approach.
What's your role under data protection law for this data?
We act as a processor for the Companies House personal data relayed through your watchlist — you remain the controller. See the privacy policy, Section 3.
