UK Companies House Search & New Company Leads

Search every UK registered company (about 5.7 million) using Companies House's official Free Company Data Product, and get newly incorporated companies as lead lists. Filter by SIC code, company name keywords, postcode or post town, status, company type, accounts category, overdue accounts and outstanding charges. Each result includes registered address, SIC codes, accounts and confirmation-statement due dates, mortgage/charge counts and previous names.

No scraping and no CAPTCHAs: the Actor streams the official monthly bulk file straight from Companies House. A full-register scan takes about 15–30 seconds, and a new-incorporations list is ready in seconds. You can add your own free Companies House API key to append current officers/directors to each company.

Use cases

• New business leads: companies incorporated in the last 30 days in your SIC codes and postcodes. Useful for accountants, banks, insurers, web agencies, office suppliers and SaaS.
• Market mapping: every active company in a sector (e.g. SIC 56101 restaurants in Leeds).
• Distress & credit signals: accounts overdue, liquidation or administration status, outstanding charges.
• KYB / enrichment: registered address, status, type and previous names for a list of companies.

Freshness

Companies House publishes this file monthly (snapshot date is on every item, e.g. 2026-10-01). Companies incorporated after the snapshot appear in the next month's file. "Overdue" flags are computed against today's date, so a company may have filed since the snapshot. Check companiesHouseUrl for live status. For real-time lookups, add your API key; officers are then fetched live.
