Which route fits

1. Free bulk file, whole register. Companies House publishes "Basic Company Data" as one CSV zip (about 471 MB, refreshed monthly) at download.companieshouse.gov.uk. Name, number, address, status, SIC codes and incorporation date. No officers, owners or filings, and you filter it yourself.

2. Free API with your own key. Register at developer.company-information.service.gov.uk. Search, filters, profiles, officers, owners and filing history, 600 requests per 5 minutes. The API does not answer calls made from a web page (browsers get 403), and a key must not sit in a public page, so there is no in-browser search here. You need a script.

3. Filtered lists without code: the Apify actor. Our actor runs the official API for you: filter by status, SIC code, dates and location, add officers, owners and filings, export CSV, Excel or JSON, schedule a daily run for new companies. No scraping.
