UK Business Check API
/uk_business_check
Performs a synchronous check of a single UK company by its Companies House company number. This is the UK equivalent of the Australian /business_check endpoint: one request, one JSON reply, no polling.
The response combines the Companies House company profile, the full list of current and resigned officers, and the most recent filing history into a single flat match object.

Technical Use Cases tag
Onboard a UK counterparty
One synchronous call at signup returns company_status, type and date_of_creation, so you can pass, fail or escalate before the form closes. No job to queue, no webhook to wait on.
Pull the officer list straight into screening
officers[] returns every current and resigned appointment, actives first. Feed the names into PEP and sanctions screening, and pass any officer_id to the officer report endpoint for the full appointment history.
Create Company House Officer Report API arrow_forwardRe-check at the moment of risk
Trigger a fresh lookup when a single customer changes bank details, asks for a credit increase or renews a contract. company_status_detail and the newest filing_history entry reflect Companies House as of that request, not as of onboarding.
