UK Companies House Bulk Company Data (No API Key)

Search and export every live UK company from the official Companies House Free Company Data Product — the free monthly bulk snapshot that Companies House publishes for download. No Companies House account, no API key, no scraping of the Companies House website.

Filter by company name, SIC code, status, company type, incorporation date, post town, postcode district or company number, and get clean JSON/CSV/Excel rows with SIC descriptions, accounts and confirmation statement due dates, overdue flags, charge counts and a link to each company's Companies House page.

What you get

• About 5.7 million live companies (private and public limited companies, LLPs, limited partnerships, CICs, CIOs, overseas entities, registered societies and more).
• One row per company: number, name, type, status, incorporation date, country of origin, up to 4 SIC codes with descriptions, registered office post town and postcode district, accounts category, accounting reference date, last accounts date, next accounts due date, confirmation statement due date, overdue flags, mortgage charge counts, number of previous names, and the Companies House URL.
• The snapshot date on every row, so you always know how fresh the data is.
• Stops early: the snapshot is streamed and filtered on the fly, and the run stops as soon as it has what you asked for (the Quick start takes about 2 seconds). Searches that must read the whole snapshot take longer — see Speed and cost.

Quick start — verified input

{
  "maxItems": 20
}

An empty input does the same: the first 20 companies of the current snapshot (company-name order), in a few seconds.

Field notes:

• Dates are ISO YYYY-MM-DD. accountsOverdue / confirmationStatementOverdue compare the due date with the snapshot date (true = the due date had passed when the snapshot was taken; the company may have filed since).
• The accounting reference date (year end) is accountingReferenceDay / accountingReferenceMonth; the next accounts are made up to that day following accountsLastMadeUpDate.
• companyType / companyStatus are the texts as published; companyTypeCode / companyStatusCode are stable codes for filtering.
• sicCodes[i] belongs to sicDescriptions[i]. Companies with "None Supplied" have empty lists. A few older companies still carry 4-digit SIC 2003 codes.
• dissolutionDate is always null: the product lists live companies only.
• The RUN_SUMMARY record in the run's key-value store holds the snapshot date, how many parts and bytes were read, why the run stopped, and (for company-number lookups) the numbers that were not found.

How it works, speed and cost

Companies House publishes the snapshot as 7 ZIP files (about 490 MB; about 2.8 GB of CSV; 5.7 million companies) in company-name order, within 5 working days of each month end; it covers the register up to the end of the previous month. This Actor reads the product page, then streams the ZIP files in order, decompresses and filters them in memory (nothing is stored), pushes the matching companies, and closes the download as soon as maxItems companies are found (or all requested company numbers).

• Searches that reach maxItems early finish in seconds and download only the start of the first file (the Quick start: about 2 seconds, 2 requests, 0.1 MB). Broad filters often stop inside the first file, e.g. active software companies in London with maxItems up to a few thousand.
• Searches that must look at every company take about 20-30 minutes: company-number lookups where a number is missing, narrow filters (a rare SIC code in one postcode district) and large exports. Measured in October 2026 at the default 256 MB: two whole-snapshot reads took 24 and 26 minutes, because most files download from the Companies House CDN to Apify at only about 0.3 MB/s. The Actor mostly waits during that time, so platform usage stays small (about 0.1 compute units for a full read).
• Put many lookups in one run (up to 50,000 numbers) rather than many runs: one full read serves them all.
• The run keeps going for up to its timeout (default 1 hour) and stops 90 seconds before it with the rows found so far (complete: false in RUN_SUMMARY), so a short timeout never loses what was already found.
• Results come in company-name order. If you want "the newest" companies, filter by incorporatedFrom instead of relying on order.

Empty results?

• Dissolved companies are not in the snapshot. It lists live companies only (active, proposal to strike off, liquidation, administration, receivership, voluntary arrangement).
• Very new companies appear once a month: the snapshot covers incorporations up to the end of the month before its date (see snapshotDate).
• Post towns are free text typed by the filer. If postTowns finds little, use postcodeDistricts (e.g. "M1" or the area "M").
• All filters must match together. Remove one and try again.
• Keywords match whole words: "tech" does not match TECHNOLOGY; use "tech*".

Common input mistakes

Wrong	Right	Why
"sicCodes": ["software"]	"sicCodes": ["62012"] or "companyNameKeywords": ["software"]	SIC codes are numbers
"postcodeDistricts": ["London"]	"postTowns": ["London"]	towns and postcodes are separate filters
"postTowns": ["SW1A 1AA"]	"postcodeDistricts": ["SW1A"]	only the district (first half) is compared
"statuses": ["dissolved"]	(not available)	the snapshot lists live companies only
"incorporatedFrom": "09/01/2026" meaning 1 September	"incorporatedFrom": "2026-09-01"	slash dates are read as UK day/month/year
"companyNumbers": ["ACME LTD"]	"companyNameKeywords": ["acme"]	numbers look like 00445790 / SC668770

Privacy: what is deliberately left out

• No officers, no PSCs (persons with significant control), no contact details: the product contains none, and this Actor never requests any officer or PSC source.
• The registered office is reduced to the post town and the postcode district (e.g. LONDON, EC1V). Street address lines, care-of names, PO boxes, counties and full postcodes are dropped, because a small company's registered office is often a director's home. Post towns that contain a house number or a street name are cut down or left empty.
• Previous company names are counted (previousNamesCount), not listed.

Legal and attribution

• Unofficial tool, not affiliated with or endorsed by Companies House. It uses only the publicly downloadable Free Company Data Product (https://download.companieshouse.gov.uk/en_output.html, robots.txt allows all paths).
• Source: Companies House. Companies House states: "Companies House imposes no rules or requirements on how the information on the public register is used." Its re-use guidance also says customers must take their own legal advice on possible third-party copyright, must not reproduce the Crown insignia, and must credit Companies House as the source when using information from its guidance, website, publications or statistics. Every row carries source, sourceUrl and license for attribution.
• Company register data is public, but you are responsible for how you use it, including UK GDPR / the Data Protection Act 2018 and the PECR rules on electronic marketing. Company names can contain personal names (e.g. a sole director's company); treat them accordingly.
• The data is a monthly snapshot and is provided "as is"; Companies House does not verify the information companies file. Check the Companies House page (companiesHouseUrl) for the latest filings before relying on a record.
