UK Companies House Search: by SIC Code, Postcode, Town

Find every UK company in an industry and area, straight from the official Companies House register of more than 5 million companies. Filter by SIC code, postcode area or district, town, name, company type, accounts size and incorporation date, and download the list as Excel, CSV or JSON.

• ✅ Complete: scans the whole official register snapshot, not a search page that stops after a few hundred results
• ✅ SIC codes with prefixes: 62 finds all IT companies, 56101 only licensed restaurants
• ✅ Exact postcode logic: B is Birmingham only (not Bath BA), SW1A is one district, SW1A 1 one sector
• ✅ New companies: filter by incorporation date to find businesses founded last month
• ✅ Clean data: registered office address, all SIC codes with descriptions, status, company type, accounts and confirmation statement dates, previous names and a link to the Companies House page
• ✅ No API key, no login, dormant companies left out by default

What can you use it for?

• B2B lead lists: all accountants in Manchester, all software companies in London EC, all builders in Leeds
• Market research: count companies per industry and region, track new incorporations
• Sales territories: split leads by postcode district

Tips

• SIC codes: look up codes in the official list (UK SIC 2007). Use 2 to 4 digits for a whole group, 5 digits for one activity.
• Postcodes are more reliable than towns, because the town field is free text (LONDON, London, City of London).
• Company size: the accounts category is a rough size signal. MICRO ENTITY and TOTAL EXEMPTION are small companies; FULL, MEDIUM and GROUP are larger ones.
• Registered office: the address is the registered office, which can be an accountant's office rather than the place where the company trades.

Speed and pricing

The Actor reads the complete register snapshot in a few seconds to about 2 minutes, depending on the filters (SIC code and name filters are fastest). It stops early when Max results is reached. You pay per company in the results.

Paid Apify plans pay less: 10% off on Starter, 20% on Scale and 30% on Business and higher plans.

Data source and license

Data: Companies House "Free Company Data Product", updated monthly. Contains public sector information licensed under the Open Government Licence v3.0. The snapshot date of every result is in snapshotDate. This Actor does not output officers, persons with significant control or contact persons, and leaves out "care of" address lines.

Using the data for marketing: company data is public, but UK rules (PECR and UK GDPR) still apply when you contact businesses, especially sole traders and partnerships. Check the rules for your channel before sending emails or calling.
