FAQ

Is there a Companies House API I can use without registering? Yes, this Actor works out of the box with no key: give it company numbers or names and it returns official Companies House data. If you need dedicated rate limits, you can optionally add your own free Companies House key.

Do I need a Companies House API key? No. It works out of the box. If you run very large volumes you can optionally add your own free key for dedicated rate limits.

Can I check a list of UK companies in bulk? Yes. Pass hundreds of company numbers (fastest) or names in one run; each company becomes one flat record. Not-found lookups are free.

What data do I get for each company? Status (active, dissolved, liquidation...), company type, incorporation and dissolution dates, SIC codes, registered office and postcode, next accounts and confirmation statement due dates, overdue flag, insolvency history and charges. Company facts only — no officer or PSC personal data.

Can I call it from Python, JavaScript, Make, Zapier or an AI agent? Yes. Run it through the Apify API or official Python/JavaScript clients, connect it to Make, Zapier, n8n, Slack or Google Sheets via Apify integrations, or expose it to AI agents through the Apify MCP server. Input is small and output is deterministic flat JSON.
