UK Director & Ownership Changes (Companies House)

Track new and departing directors and changes of owner at UK companies, either for a watchlist you choose or across the whole UK, filtered by area and industry. One row per change, with the date, the person and their role, straight from the official Companies House register.

A new director is a new decision-maker. A departing one can mean a change of direction. A new owner can mean a takeover. If you sell to, lend to, insure or monitor UK companies, these are the moments that matter, and Companies House publishes every one of them. This Actor works two ways:

• Watchlist: checks the companies you list and tells you exactly what changed since the date you choose.
• Market-wide feed: reads every change across the UK in the last 1 to 48 hours from Companies House's live data stream, and keeps the ones in your area and industries. Thousands of changes happen every day.

3. Narrow it with Town or city, Postcode areas, Country, Industries or SIC codes, and pick which changes you want.
4. Click Start. Reading a day of changes takes a few minutes; matches then appear in the Output tab, newest first.
5. Schedule it daily with a 24-hour look-back and you'll see every new director and owner in your patch, every morning.

How to use it: watchlist

1. List your companies

Paste company numbers (00445790, SC095000) or Companies House links, one per line. Numbers without leading zeros are fine (445790). Up to 1,000 per run.

2. Choose the period

Changes in the last N days (default 30), or a Changes since date.

3. (Optional) Choose which changes

Leave empty for all four, or pick only appointments, resignations, or owner changes.

4. Click Start

Results appear in the Output tab, newest first. A watchlist of 100 companies usually takes about two minutes.

5. Run it on a schedule

Create a weekly schedule with Changes in the last 7 days and connect it to email, Slack, Google Sheets or your CRM. You only hear about real changes.

Pricing

Event	Price
Change	$0.01
Feed scan	$0.03

For example, 50 changes cost $0.50; a whole-UK feed run that finds changes adds one $0.03 feed scan.

You pay per change found. Market-wide feed runs also have one small feed scan charge, only when the run finds at least one change, because each one reads a full day of Companies House's live data. You are never charged for companies with no changes, company numbers that don't exist, or a run that finds nothing. Set a maximum cost per run and the Actor stops cleanly when it's reached.

No Companies House account or API key needed. Works with AI agents, including x402 pay-per-call payments.

Honest limits

• Dates are the dates Companies House records, which is when the change took effect, not when it was filed. A change filed late appears with its real (earlier) date.
• The feed reaches back 48 hours at most, because Companies House's live stream only keeps a few days of history. A change filed today but dated earlier than the window isn't included.
• Feed runs with tight area filters take longer, because each change's company is looked up to check its location.
• Very large companies are capped at 1,000 officers and 1,000 owners per list, which covers almost every company.
• Owner statements (for example "the company knows of no PSC") are not reported as changes.
• Companies House does not publish full dates of birth or home addresses, and this Actor does not try to find them.

FAQ

Does it find new directors across a whole town or industry? Yes, use the market-wide feed. It covers the last 48 hours at most, so run it daily for a continuous record.

Why is a secretary listed under officer_appointed? Directors, secretaries and LLP members are all "officers" at Companies House. Use the role field to tell them apart.
