Companies House UK Company Data & Accounts
Pricing
from $2.10 / 1,000 company records
Companies House data with no API key needed: look up UK companies by number or name and get status, SIC codes, filing deadlines and overdue flags, charges, insolvency, and turnover, profit and net assets from the latest accounts. Company-level only, no personal data. Failed look-ups are free.
UK company numbers to look up, or register page links such as https://find-and-update.company-information.service.gov.uk/company/00445790 (the number is read from the link). Spaces are removed and letters uppercased; purely numeric numbers are left-padded to 8 digits (e.g. 445790 → 00445790, "0050 2851" → 00502851) and prefixed ones to two letters plus 6 digits (SC45551 → SC045551). Prefixes such as SC, NI and OC are kept. A value that is still not a valid company number returns a free error item. If this, the searches and the advanced-search filters are all empty, the run returns one example company (00445790), free of charge.
Company-name search queries. Each hit is fetched as a full company profile.
[]Maximum number of search hits to take from each query (1–100).
Find companies by industry, place, incorporation or dissolution date, status and type, using the official Companies House advanced company search. Each match is returned as a full company record (marked matchedFilter) and charged like a name-search hit. Set at least one filter; leave all empty to skip. A key not listed here fails the run before any request. A run returns at most 1,000 companies (25 on the free plan), whatever maxResults says. If Companies House rejects the filters, the run fails with its reason after the companies asked for by number or name are returned.
Include the 10 most recent filing-history items for each company.
Download the latest electronically filed accounts (if available as iXBRL) and extract headline figures. Includes the prior-year figures the same accounts carry (previous) and the year-on-year change (change).
Compare each company with what the previous run of the same watch list saw and add changes (field, from, to) for status, status detail, overdue accounts and confirmation statement, outstanding charges, insolvency history, registered office area, company name, the latest filing, and each new filing (up to the latest 50 filings). The first run of a list is the baseline for each company (changedSinceLastRun null). The last-seen state is kept per watch list in a key-value store named uk-companies-house-watch in your own Apify account. Schedule the run (best as a saved task) to watch a list daily or weekly.
With Watch for changes on: return (and pay for) only companies that changed since the last run. The first run returns every company as the baseline. Companies that could not be fetched are always returned as free error items.
Optional. Snapshots are kept separately per watch list, so two lists (or two tasks) watching the same company each get their own baseline and each see every change. Default: the saved task when the run belongs to a task, otherwise the exact set of companies, searches and filters, so editing that input starts a new baseline. Set a name to keep one list across edits or to share it between tasks. Case and extra spaces are ignored. Lists watched before this option existed start a new baseline once.
