Companies House API - UK Company Search, Officers, Filings

Search the UK register by company name, then read the full register entry, the officers current and resigned, and the complete filing history. All four endpoints return structured JSON from the official UK registry.

When to trigger

Use this skill when the user asks to:

• Find a UK company's registration number from its name
• Check whether a UK company is active, dissolved, or overdue on its accounts
• List a company's directors and secretaries, current and resigned
• Read a company's filing history and pull the filed PDFs
• Run KYB or due-diligence checks on a UK counterparty
• Look up SIC codes, incorporation dates, registered offices or previous names
• Build UK B2B datasets or company-monitoring pipelines
