UK Companies House Lookup & Monitor

Give it your list of UK companies — Companies House numbers or names, one per line — and get one record per company from the official Companies House API (no scraping): name and number, status and status detail, type, jurisdiction, SIC codes, incorporation and dissolution dates, previous names, registered-office area, accounts (type, last period end, next due, overdue flag), confirmation statement (last made up to, next due, overdue flag), insolvency and liquidation flags, charges (totals plus the latest 25 with status and dates), the latest 25 filing events (date, category, form type, description code) and corporate persons with significant control with their natures of control.

Monitor it

Set Mode to Monitor and schedule the run (daily is plenty — the register updates overnight). The previous run's records are the baseline, kept in this actor's key-value store, so each run returns only the companies that changed: new to your list (change: added), changed on the register (change: changed, with changed_fields naming what moved — status, accounts_overdue, charges_outstanding, filings_total, corporate_controllers, …) or gone from the register (change: removed). Unchanged companies push nothing and cost nothing. Pipe the dataset to Slack, email, Sheets or a webhook with any Apify integration.

What people use it for

• Credit control and supplier onboarding — accounts or confirmation statement overdue, new charges, status moving to "liquidation" or a strike-off gazette filing.
• KYB refresh — re-check a client book monthly for status, SIC and controller changes.
• Portfolio watch — competitors, customers or investees: new filings and charges as they land.

Organisation-level data only: officers and individual PSCs are never included (filing events carry the form and description code, e.g. AP01 / appoint-person-director-company-with-name-date, not the person's name), charge holders are omitted and registered-office street lines are dropped.
