How this service works
UK company check from the official Companies House register. Give a company number; get its status, type, incorporation date, SIC codes, registered office, whether accounts or the confirmation statement are overdue, insolvency and charges flags, and the number of active officers. Company-level facts only, no personal data. Use for supplier checks, sales research and due diligence on UK companies.
Output
Returns an array of matching company records, each containing the company's official status (active, dissolved, etc.), company type, incorporation date, SIC codes, registered office address, flags for overdue accounts and confirmation statement, insolvency indicators, charges flags, and the count of active officers. Company-level facts only; no personal data on individuals.
Example use cases
Supplier onboarding due diligence
“Before we onboard this new supplier, can you check 'Acme Logistics Ltd' on the UK Companies House register and tell me their status, whether they have any insolvency flags or outstanding charges, and if their accounts are overdue?”
Sales prospect research
“I'm about to cold-call a prospect — can you pull the Companies House record for 'BrightPath Digital Limited' so I know their company type, SIC codes, incorporation date, and how many active officers they have?”
Contract counterparty verification
“We're about to sign a contract with 'Meridian Construction Group' — can you verify they're still active on Companies House, check for any insolvency or charges flags, and confirm their registered office address?”
Technical details
Endpoint
GEThttps://uk-company-check.agent-fee-check.workers.dev/search?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need authoritative, government-sourced company facts about any UK-registered entity — especially for supplier vetting, contract due diligence, sales research, or compliance checks. Prefer this over generic web search when you need structured, reliable fields like company status, SIC codes, insolvency flags, and overdue filing indicators directly from the official Companies House register.
Side effects
- Company name not found — returns empty results array if no match exists in Companies House
- Ambiguous name query — returns multiple records requiring the caller to disambiguate by company number
- Companies House API unavailable — upstream outage may cause timeout or error response
- Invalid or malformed query parameter — may return error if 'q' is missing or empty
- Company dissolved long ago may have limited data in results
