How this service works
Check a UK company on the official Companies House register by company number: name, status (active, dissolved, liquidation), type, incorporation date, registered address, SIC codes, accounts due or overdue, charges, insolvency history and current directors. Use for supplier checks, due diligence, or confirming a business is real and active. Errors: 400 invalid number, 404 not found.
Output
A structured record from the Companies House register including: company name, current status (active, dissolved, liquidation, etc.), company type, incorporation date, registered address, SIC codes, accounts filing due or overdue status, any registered charges, insolvency history, and current directors list.
Example use cases
Supplier due diligence check
“Before we sign this contract, can you verify that our UK supplier — company number 09876543 — is active on Companies House, not in liquidation, and doesn't have any insolvency history?”
Confirming a new business partner is real
“A company called Brightfield Solutions says their Companies House number is 12345678 — can you look them up and confirm the name matches, they're still active, and tell me their registered address and directors?”
Checking overdue accounts and charges
“I need to do a quick credit check on company number 07654321 — can you pull their Companies House record and let me know if their accounts are overdue and whether there are any registered charges against them?”

Endpoint
GEThttps://agent-tools-production-e6aa.up.railway.app/v1/uk-company/:number?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need authoritative, official data about a UK-registered company directly from the Companies House register. Prefer this over general web searches or third-party business data providers when accuracy of legal status, directorship, and filing compliance is critical — for example, in supplier vetting, contract due diligence, or fraud prevention workflows.
Side effects
- 400 Bad Request — company number format is invalid or malformed
- 404 Not Found — company number does not exist on the Companies House register
- Dissolved or struck-off companies may return records but with non-active status
- Leading zeros in company numbers are optional but may affect lookups if omitted incorrectly
