How this service works
Is this UK company legit and safe to deal with? One-call due-diligence check from Companies House: profile, directors and their track record at other companies (phoenix-company check), beneficial owners (PSCs), charges, insolvency, overdue filings and risk flags, with a source link for every fact.
Output
A structured due diligence report covering: company profile (name, status, type, address), list of directors with their track record at other companies (phoenix-company indicators), persons with significant control (PSCs/beneficial owners), registered charges, insolvency events, overdue filing history, and aggregated risk flags — each fact accompanied by a source link to the underlying Companies House record.
Example use cases
Supplier vetting before contract signing
“Before we sign a contract with this UK supplier, can you check company number 09876543 for any risk flags — past insolvency, phoenix directors, overdue filings, or outstanding charges?”
Investor screening a startup
“I'm thinking of investing in a UK startup registered as company number 12345678 — can you pull a full due diligence report including who the beneficial owners are and whether any directors have a dodgy history at other companies?”
Fraud check on a new client
“A new client wants to pay us upfront but something feels off — can you do a Companies House due diligence check on UK company number SC654321 and tell me if there are any insolvency, charges, or phoenix company warning signs?”

Endpoint
GEThttps://uk-company-check.fly.dev/v1/uk/company/:number/check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, single-call due diligence snapshot of a UK-registered company — combining profile, director history, ownership, charges, insolvency, and risk flags in one response. Prefer this over the raw Companies House profile endpoint when you need risk assessment beyond basic company info, or when checking for phoenix directors and PSCs matters. Ideal for supplier vetting, investor screening, fraud detection, and KYC workflows involving UK companies.
