How this service works
Search the official UK company register (Companies House) by company name. Returns up to 10 matches with company number, status, incorporation date and postcode.
Output
Returns up to 10 matching UK companies with their company number, company name, current status (e.g. Active, Dissolved), incorporation date, and registered postcode.
Example use cases
Supplier due diligence check
“I need to verify that 'Apex Logistics Solutions' is a real registered UK company before we sign a contract — can you search Companies House for it and tell me its company number, status, and when it was incorporated?”
Finding a competitor's registration
“Can you look up 'Monzo Bank' on the UK company register and get me their official company number and registration details?”
Checking a job offer legitimacy
“I got a job offer from a company called 'Brightpath Recruitment Ltd' — can you search Companies House to see if they're actually registered in the UK and whether they're still active?”
Technical details
Endpoint
GEThttps://uk-company-check.fly.dev/v1/uk/company/search?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to discover UK company registration details by name — especially when you don't already know the company number. Prefer this over the by-number lookup when starting from a company name. Choose this for initial due diligence, supplier verification, or any scenario where you need to confirm a UK business exists and is active on the official register.
Side effects
- No results found if the company name is misspelled or does not exist on the register
- Returns multiple ambiguous matches when a generic name is queried (e.g. 'Smith')
- Rate limiting or service unavailability from the underlying Companies House API
- Payment failure via x402 protocol resulting in a 402 response
- Empty result set for very new companies not yet indexed
