UK New Companies Feed: Companies House Incorporations

UK New Companies Feed — Companies House incorporations & dissolutions

Get every new UK company registered yesterday (and every company dissolved) straight from the official Companies House register — with SIC codes, plain-English nature of business, sector, company type, registered office postcode and a link to the Companies House page. No API key, no login, no Companies House developer account.

Run it once for a quick list, or schedule it daily with New since last run mode to get only companies you have not seen before.

Who it's for

• B2B sales & lead generation — accountants, banks, insurers, payroll, web designers, POS/payments, telecoms and office suppliers who sell to brand-new businesses.
• Local market watchers — new restaurants, bars, gyms, builders or agencies in a postcode area (e.g. M, EC1, BS, G).
• Credit, risk & KYC teams — track dissolutions / strike-offs of suppliers and customers.
• Researchers & journalists — daily company formation and dissolution counts by sector and region.

The Actor makes one polite request per day per event type (big Tuesday strike-off batches are split automatically to stay under the 5,000-row export limit), with a descriptive User-Agent and spacing between requests. Not affiliated with or endorsed by Companies House.

Privacy: company-level data only. Officers, persons with significant control and other personal data are never requested. Flat/apartment/room numbers are removed from addresses, and companies named only after a person (e.g. "JOHN SMITH LTD") are skipped by default.

Event	Price
Actor start	$0.005 per run
Company record	$0.003 per company event delivered

Tips & FAQ

• How fresh is it? Companies House publishes incorporations the same day; run after midnight UK time for yesterday's full list.
• Why fewer records on Saturdays? Fewer incorporations are registered at weekends; dissolutions are published in batches (Tuesdays are largest).
• Directors / contact details? Not included — this feed is company-level only by design.
• Need the whole day? Set maxItems high (e.g. 5000) — a weekday is typically 2,000–4,000 incorporations.
