UK Companies House Leads (no API key)

Turns the official Companies House monthly bulk snapshot (5M+ UK companies) into clean, filtered lead rows in seconds — no API key, no rate limits, no scraping of the website.

What makes it different

• Mass-address filter – formation-agent / virtual-office addresses host hundreds or thousands of companies and pollute "new company" lead lists. Set maxCompaniesAtSameAddress (e.g. 20) to drop them; every row also carries companiesAtSameAddress.
• Only-new mode – schedule it monthly with onlyNewSinceLastRun and each run returns only companies you have not received before.
• Distress / compliance signals – accountsOverdue, confirmationStatementOverdue, chargesOutstanding, status filters (liquidation, strike-off proposals…), accounts category (dormant, micro…).
• Clean typed output: ISO dates, ageDays, SIC codes and descriptions, structured address, previous names, direct Companies House link.

What can I do with it?

• New-company lead lists: companies incorporated in the last N days, by SIC code (e.g. 62 software, 56 restaurants, 41 construction), postcode area or town. Typical buyers: accountants, banks and fintechs, insurers, web agencies, B2B SaaS, payroll, office and legal services.
• Monthly "only new" feed: schedule the Actor with onlyNewSinceLastRun and each run returns only companies you have not received before (per feedName).
• Distress and compliance signals: companies with overdue accounts or confirmation statements, outstanding charges, or a given status (liquidation, strike-off proposals...), for credit control, insolvency and recovery prospecting.
• Market mapping: count and list companies by SIC, town or incorporation period.
• Enrichment input: a clean list of company numbers to feed CRMs, n8n/Make/Zapier or AI agents.

FAQ

Do I need a Companies House API key? No. The Actor reads the official monthly bulk snapshot (Free Company Data Product), so there are no API keys and no rate limits.

How fresh is it? Companies House publishes the snapshot within about 5 working days after each month end; results can be up to ~5 weeks old. For one company's live status, open companiesHouseUrl.

What does the mass-address filter do? Formation agents and virtual offices register hundreds or thousands of companies at one address. maxCompaniesAtSameAddress drops companies at addresses shared by more than N companies, and every row carries companiesAtSameAddress so you can decide yourself. In one test (software SIC 62/63, last 60 days) this removed 47 % of the companies; your share will vary by filter.

Does it include directors, PSCs or contact details? No. Only company-level data from the snapshot (no officers, no emails or phones). For live officer data use Companies House itself.

How does onlyNewSinceLastRun work? The Actor stores the company numbers it delivered per feedName in a key-value store in your Apify account and skips them in later runs. You pay only for rows delivered.

How long does a run take and what does it cost? The snapshot has to be read on every run (a couple of minutes), so each run has a small fixed start fee plus the per-company price; see Pricing.

Which formats? JSON, CSV, Excel, XML, HTML or RSS from the dataset, or the Apify API.

Data freshness & limits

The source snapshot is published by Companies House within ~5 working days of each month end and covers live companies up to the previous month end, so results can be up to ~5 weeks old. For one company's live status follow companiesHouseUrl. Results are sorted newest incorporation first.
