How this service works
Agent402 UK. Companies House profile lite (name, status, address, SIC, accounts due). Cached public register data — not an official CH service. Requires server COMPANIES_HOUSE_API_KEY. Query number=.
Output
A lite company profile object containing the official registered company name, current status (e.g. active, dissolved), registered address, SIC code(s) describing the business activity, and the date by which next accounts are due at Companies House. Data is sourced from cached public register data and is not a real-time official CH response.
Example use cases
Vendor due diligence check
“Before we sign this contract, can you look up Companies House details for company number 09876543 — I want to confirm they're still active, see their registered address, and check their SIC code.”
Accounts filing deadline reminder
“When are the next accounts due for UK company number 07654321? Pull the Companies House profile so I can add the deadline to our compliance calendar.”
Enrich CRM with company data
“We have a new UK client whose company number is 11223344 — can you fetch their official registered name, address, and industry SIC code from Companies House so I can fill in their CRM record?”
Technical details
Endpoint
POSThttps://agent402.co.uk/v1/data/uk/companyWhen to prefer
Use this endpoint when an agent needs quick, structured UK company profile data (name, status, address, SIC, accounts due) by company number and a lightweight cached result is acceptable. Prefer over scraping Companies House directly or using LLM approximation. Note this is not an official CH service — for compliance-critical or real-time official data, use the Companies House API directly.
Side effects
- Invalid or non-existent company number returns an error or empty result
- Cached data may be slightly stale compared to live Companies House register
- Missing server-side COMPANIES_HOUSE_API_KEY causes authentication failure
- Rate limits or upstream CH API outages may cause service unavailability
- Non-UK company numbers are not supported
