Verify UK businesses with structured registry data and ongoing monitoring
Use Entylink to verify UK businesses with company, officer, PSC, and filing data, then keep those entities monitored over time through an API built for operational teams.
Built for engineering and operational teams
What the API gives you
Verification in five API calls
A complete UK business verification checks that the company exists and is active, confirms the registered address, reviews current officers and their appointment dates, inspects PSCs and natures of control, and reads recent filings. All five calls share the same API key.
Built for the step between submission and approval
Entylink is designed for the product step that sits between a user submitting their business details and your team approving the application — structured registry data in a form engineers can integrate in hours.
Keep verified businesses monitored after the first check
Once verified, subscribe the company to webhooks. Changes to officer appointments, PSC records, or filing status are delivered to your endpoint — so ongoing reviews can be event-driven rather than manually scheduled.

Frequently asked questions
Is this a full KYB platform?
The positioning here is around registry-backed business verification and monitoring. It is intentionally narrower and more developer-native than a generic all-in-one vendor claim.
What does a passing UK business verification look like?
Company status is active, incorporation date is plausible for the business type, at least one current officer appears in the record, PSC records are present and coherent, and there are no red-flag filings such as a first gazette notice or a striking-off application.
Which teams does this page convert best?
Fintech onboarding, compliance, fraud, credit, and supplier-risk teams are the closest fit because they already operate verification workflows tied to business entities.
