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. Accepts a company name or number.
Output
Returns a structured due diligence report including: company profile (name, number, status, type, registered address), director list with their roles at other companies and phoenix-company risk indicators, persons with significant control (PSCs/beneficial owners), outstanding charges, insolvency and dissolution flags, overdue filing alerts, and an overall risk assessment — with a source link to Companies House for every fact.
Example use cases
Supplier vetting before contract signing
“Before we sign this contract, can you check whether 'Brightfield Construction Ltd' is a legit UK company — look into their directors' track records, any phoenix-company red flags, beneficial owners, charges, and whether their filings are overdue?”
Investment target background check
“I'm considering investing in a UK startup called 'NovaTech Solutions Ltd' — can you run a full company check on them, including who controls it, any outstanding charges, insolvency history, and whether the directors have any dodgy history at other companies?”
Fraud screening for new customer
“We've got a new B2B customer claiming to be 'Meridian Trading UK Ltd' — can you verify they're a real registered UK company and flag anything suspicious like overdue filings, insolvency, or directors with a pattern of failed companies?”
Technical details
Endpoint
GEThttps://uk-company-check.fly.dev/v1/uk/company/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 — covering directors, ownership, charges, insolvency, and filing compliance — without having to stitch together multiple Companies House API calls yourself. It is ideal for agent workflows that need fast, structured risk assessment of UK counterparties before contracts, payments, or partnerships. Prefer it over raw Companies House API access when you want pre-aggregated risk flags and director track-record analysis in one response.
Side effects
- Company not found: returns empty or not-found result when the name or number doesn't match any Companies House record
- Ambiguous name: a company name may match multiple companies, requiring the caller to use the company number for precision
- Stale data: Companies House data may have a short lag, so very recent changes may not appear
- Invalid input: missing or malformed 'q' parameter returns a 400-level error
- Service unavailable: the fly.dev deployment may be temporarily down, returning a 5xx error
