UK Companies House Company Data & Monthly Changes

Search and export UK company data from Companies House without an API key. Filter the full UK register (≈5.6 million companies) by SIC code, postcode, company status, company type and incorporation date, or get a monthly change feed of new incorporations, dissolved companies and status changes (for example companies entering liquidation or administration).

What you can do

• Build lists of UK companies in an industry (SIC 2007 codes, e.g. 62 for IT, 56101 for restaurants) and area (postcode prefix, e.g. EC1, M14, EH).
• Find companies incorporated in a date range, e.g. all new Private Limited Companies in Manchester last quarter.
• Monitor the register month to month: newly registered companies, companies dissolved or removed, and status changes such as Active → Liquidation.
• Export to JSON, CSV, Excel or via the Apify API, and schedule monthly runs.

Company-only data: no directors, officers, PSC or shareholder data.

Modes

Mode	What it returns
snapshot	Companies from the newest monthly snapshot that match your filters. Stops as soon as maxItems matches are found.
monthlyDiff	Differences between the newest and the previous monthly snapshot: new (on the register now, absent last month: mostly new incorporations, occasionally restorations), dissolved (status became Dissolved or the company is no longer on the register), statusChanged (any other status change).

The diff is computed from two monthly bulk snapshots, so no Companies House API key is needed. Companies House publishes a new snapshot within about 5 working days after month end; the Actor picks the newest automatically (or set snapshotDate).

Input

Field	Description
mode	snapshot (default) or monthlyDiff
changeTypes	new, dissolved, statusChanged (monthlyDiff; default all)
sicCodes	SIC codes or prefixes; any match counts
postcodePrefixes	Registered-office postcode prefixes, spaces ignored
companyStatuses	e.g. Active, Liquidation, In Administration
companyTypes	e.g. Private Limited Company, Limited Liability Partnership
incorporatedFrom / incorporatedTo	YYYY-MM-DD, inclusive
snapshotDate	Optional YYYY-MM-01; default newest
maxItems	Max results, default 100

Example: new IT companies in London EC postcodes this month

{"mode": "monthlyDiff", "changeTypes": ["new"], "sicCodes": ["62"], "postcodePrefixes": ["EC"], "maxItems": 100}

In monthlyDiff, companyStatuses applies to the latest status; companies no longer on the register are matched on the other filters.

Performance and cost

The ≈500 MB monthly ZIP is streamed and decompressed on the fly (never written to disk). A selective snapshot query stops early once maxItems results are found; a rare filter may scan the whole file (a few minutes). monthlyDiff reads both snapshots (and the previous one twice when dissolved is requested), typically 10–20 minutes, with a compact in-memory index (~100 MB). 2–4 GB memory is recommended.

Data source and terms

Source: Companies House Free Company Data Product. Contains public sector information

Companies House places no restriction on how the information in the Free Company Data Product is used; copyright in filed documents remains with the filing companies. This Actor is not affiliated with or endorsed by Companies House, uses no Companies House logo or crest, and does not present the data as licensed under the Open Government Licence. Keep the attribution field when you redistribute records. The Actor's price pays for the processing service, not for the data.

Personal data

The output contains company attributes only. Directors, PSC and officer data are not used. The registered-office "care of" line is dropped. Some registered offices are home addresses and some company names contain personal names; treat the output as potentially containing personal data under UK GDPR. Do not use this Actor for lead generation targeting individuals, person enrichment or profiling.

Privacy notice

Controller: Artyom Kutnevskiy (trading as LV Data Tools), contact lvdatatools@gmail.com. Version 0.1, 2026-10-14.

• Data concerned: company-level records from the Companies House Free Company Data Product: company number, name, status, type, registered-office address, SIC codes, key dates, accounts/confirmation-statement dates, charge counts and previous company names. No directors, officers, persons with significant control (PSC), shareholders or other person records are requested or output. The registered-office "care of" line is never output, because it can name an individual.
• Incidental personal data: some small companies use a home address as the registered office, and a company name can contain a person's name. These values are published by Companies House as part of the public register and are output only as company attributes.
• Minimisation: company fields only, from a fixed allowlist. No person enrichment, no matching to other sources, no contact details (emails/phones are not part of the source). The Actor must not be used for lead generation or profiling of individuals.
• Source: Companies House Free Company Data Product monthly bulk ZIP (download.companieshouse.gov.uk), streamed and processed in memory. No Companies House API key is used or embedded.
• Source terms: Source: Companies House Free Company Data Product. Contains public sector information. Companies House places no restriction on how the information is used (FOI disclosure log 362); copyright in underlying filings stays with the filing companies. The data is not presented as licensed under the Open Government Licence, and no Companies House logo or crest is used. The Actor is unofficial.
• Roles: the publisher (LV Data Tools) is controller for the Actor's own source collection and minimisation, and acts as processor for each user's run output under §5.2 of the Apify Standard Actor Contract, while the user is controller of that output and its reuse.
• Purpose: business and market research on UK companies: industry and area screening, monitoring new incorporations, dissolutions and status changes. No profiling of people or automated decision-making about individuals.
• Legal basis: Art. 6(1)(f) UK GDPR / GDPR (legitimate interest), with minimisation as described. Users must establish the basis for their own reuse.
• Recipients: the user running the Actor and recipients they choose. Apify Technologies s.r.o. provides the hosting platform. Datasets are not automatically sent to other parties by this Actor.
• Retention: LV Data Tools keeps no separate copy of output. Snapshots are streamed and not stored. Output datasets and RUN_STATS follow the user's Apify storage/retention settings. Logs contain counters only, not records.
• Transfers: hosting may involve transfers outside the UK/EEA depending on Apify's infrastructure; see Apify's privacy policy.
• Rights: access, rectification, erasure, restriction, objection (Art. 21) and complaint to a supervisory authority: UK Information Commissioner's Office (ico.org.uk) or Latvia's Datu valsts inspekcija (dvi.gov.lv). Requests concerning the Actor go to lvdatatools@gmail.com; for a user's exported dataset, contact that user as well. Corrections to the register itself are made via Companies House.
• Individual notification / Art. 14(5)(b) assessment (2026-10-14): the Actor outputs no person records; individuals appear only incidentally (home registered-office addresses, names within company names) in a public register. The publisher holds no contact details for them, and contacting them would require collecting more personal data. Individual notification would involve disproportionate effort; safeguards are this public notice, company-only fields, removal of the "care of" line, and individual handling of objections.

FAQ

Do I need a Companies House API key? No. The Actor uses the free monthly bulk product only.

How fresh is the data? Monthly. Each snapshot is compiled up to the end of the previous month.

Why might a "dissolved" company not show a dissolution date? Dissolved companies usually drop out of the bulk product, so the record shows last month's data with companyStatus = "Not in latest snapshot (dissolved or removed)" and previousStatus.

Is this official? No. It is an independent tool built on Companies House open bulk data.
