What can you use it for?

• Build lead lists by sector and area. All active bakeries in London, software companies in Manchester, construction firms in a postcode area: one run, one spreadsheet.
• Spot new businesses early. Schedule a daily run for companies incorporated since yesterday in your sector and reach them before your competitors do.
• Size a market. Count how many companies are active per SIC code and region, and how many were founded each year.
• Track insolvencies in a sector. List companies in liquidation or administration for risk monitoring, debt collection or acquisition scouting.
• Keep your data clean. Check which companies in a sector have been dissolved, with the date.

Company data only. No directors, shareholders or personal contact details: this Actor never requests them.

The columns follow one standard layout (company-registry v1), designed to stay the same for other national company registers. Download the results as Excel, CSV, JSON, XML or HTML, or pull them in via the Apify API, Zapier, Make or Google Sheets.

Data source and licence. The data comes from Companies House. Contains public sector information licensed under the Open Government Licence v3.0.

How much does it cost?

You pay per company: $2.50 per 1,000 companies (pay-per-event). A list of 200 companies costs $0.50.

• You are only charged for valid companies that land in your dataset. Searches without matches and failed requests are never charged.
• Set a maximum cost per run in the run options. The run stops cleanly when that budget is reached.
• Set Maximum results to cap the size of a run.

Built to be reliable

• Straight from the register. Data is read live through the Companies House public data API, not scraped from web pages. Website redesigns don't break it.
• Fast. A filtered list of 1,000 companies takes seconds.
• Checks that the data is real. Every record is validated (company number, name, dates, address). An empty or broken answer is retried and reported, never charged.
• Fair use built in. Requests are paced well below the Companies House rate limit. If Companies House asks to slow down, the run pauses instead of pushing on.
• Honest results. If nothing matches your filters, the run says so clearly and costs nothing.
• Clear error report. Every run saves a RUN_SUMMARY with the number of companies and any failed requests per cause: proxy, rate limit, blocked, network or other.

How to use it

1. Fill in one or more filters: SIC codes, Postcode or town, Incorporated from/to, Company status or Company name contains.
2. Set Maximum results.
3. Click Start and download your list when the run finishes (usually within seconds).

FAQ

Do I need a Companies House API key? No. The Actor works out of the box. If you run very large or very frequent jobs, you can add your own free key from the Companies House developer hub to get your own rate limit.

How many companies can one search return? Up to 10,000. This Actor is built for targeted searches: combine SIC codes, a town or postcode, dates and status to get exactly the companies you need.

How fresh is the data? It is read live from the register at the moment of your run.

Why are there no directors or e-mail addresses? By design: this Actor only collects company data, no personal data.

Is this legal? The Companies House register is public, and this Actor reads it through the Companies House public data API. Contains public sector information licensed under the Open Government Licence v3.0. You remain responsible for how you use the data, for example under UK GDPR and direct marketing rules.

Is this an official Companies House service? No. Not affiliated with or endorsed by Companies House.

A run returned fewer companies than expected. Open RUN_SUMMARY in the run's storage: it shows how many requests failed and why.
