How this service works
Search UK companies by name via Companies House — returns matches with number, status, type, incorporation date, address.
Output
Returns a list of up to 50 matching UK companies, each including company name, Companies House number, status (e.g. active, dissolved), company type (e.g. ltd, plc), incorporation date, and registered address.
Example use cases
Verify supplier legitimacy before contract
“I'm about to sign a contract with a supplier called 'Thames Valley Manufacturing Ltd' — can you look them up in Companies House and tell me if they're active, what type of company they are, and when they were incorporated?”
Enrich CRM database with official data
“I have about 15 customer companies in our system with just names and rough addresses. Can you search Companies House for each one to get their official registration numbers, confirmed addresses, and current status so we can update our CRM?”
Investigate dissolved company status
“A client claims to represent 'Pinnacle Services Group PLC' but I want to verify they actually exist. Can you search Companies House for that name and let me know if the company is active or if it's been dissolved, along with the official registration details?”
