UK Company Dossier - Companies House & Environmental Permits

One UK company, one call. Give a Company Number and get the Companies House registration record plus every Environment Agency permit tied to that company - or give a Home Office licensed-sponsor name and it is resolved to the company by exact normalised match.

Low cost

From $0.002 per dossier, down to $0.0012 at Gold. One dossier is one billed record.

What you get

Each dossier restates the published facts for one company:

• Companies House - companyNumber, companyName, companyStatus, companyCategory, countryOfOrigin, incorporationDate, dissolutionDate, registered registeredAddress and postcode (all dates are normalised to ISO YYYY-MM-DD), sicCodes, previousNames, accounts and confirmation-statement due dates, outstanding and total mortgage charges, and the Companies House chUri.
• Environment Agency - eaPermitCount, eaRegisters and eaPermits: for every waste-carrier / broker registration whose Company Number is the company's, the permit id, holder name and type, registration type and tier, activity, registered address and postcode, issue and expiry dates, and the source URL. (Only the waste-carrier register publishes a Company Number, so the other EA registers never join on this key.)
• Match provenance - matchType (exact-number / exact-normalized-sponsor / no-match / not-in-warmed-scope), needsReview, sponsorName, sponsorCandidates, sponsorCandidatesTruncated, registersMissing, asOf, companiesHouseAsOf.

Examples

Company by number:

{ "companyNumber": "08355236" }

Company by licensed-sponsor name:

{ "sponsorName": "Tetra Care Ltd" }

The default run returns company 08355236.

How the join works

• Company Number is the key. Companies House and the Environment Agency both publish it, so the join is exact - there is no name guessing on this path.
• Sponsor names are matched exactly after normalisation. Case, punctuation, &/AND and legal suffixes (Ltd, Limited, PLC, LLP) are normalised on both sides, and a trailing T/A ... trading name is dropped. Only an exact-normalised match is returned. Fuzzy matching is deliberately not offered: a 1,000-name measurement put fuzzy candidate precision at about 50%, so a near-miss would be a false identity assertion.
• Ambiguity is visible. If a sponsor name normalises to more than one company, every match is returned with needsReview=true. If the name states a legal form (Ltd, PLC, LLP, LP) that differs from the matched company's, needsReview=true as well - an exact-normalised name is not an identity assertion. A sponsor name with no exact match returns one row with matchType="no-match" and registersMissing="companies-house" - never a best guess.

Coverage and honest limits

• Measured 2026-10-31: 1,000 Environment Agency company numbers resolved to Companies House 963 / 1,000 (96.3%); 1,000 licensed-sponsor names resolved by exact normalisation 845 / 1,000 (84.5%). The unresolved sponsor names are largely non-company entities (charities, colleges, partnerships, unincorporated businesses).
• Warmed scope. The corpus covers companies that appear in an Environment Agency permit row or match a licensed-sponsor name. A Company Number outside that scope is reported as matchType="not-in-warmed-scope" with registersMissing="companies-house"; it is not evidence that the company does not exist. Use the full UK Companies House actor in this account for an arbitrary company lookup.
• Facts only. Nothing here is scored, rated, predicted or recommended. There is no officer, PSC or trustee data; company-level records only.
• Company-level data only. No individual is named or aggregated. Sponsor names are organisation names as published by the Home Office.
• asOf is the day the warmed corpus was built; companiesHouseAsOf is the date of the Companies House bulk file inside it (the bulk is published monthly, so it is normally a few weeks older than asOf). registersMissing means the company was not found in the warmed Companies House scope - it is not evidence that the company does not exist. The EA block has no separate missing state: a company with no EA registration simply has eaPermitCount=0.
• The corpus is a monthly Companies House bulk snapshot and a sponsor register refreshed whenever the owner warm runs; both are manual, not a live feed. asOf (also in meta on the actor's public store) is the build date and companiesHouseAsOf is the bulk-file date.
• A no-match or out-of-scope lookup still costs one dossier charge - the register lookup was performed and one record is delivered.

Intended use & limits

What this is. A consolidated restatement of facts published by public registers, keyed by an exact identifier. Nothing here is scored, rated, predicted, or recommended.

What this is not. Not a consumer report under the Fair Credit Reporting Act (15 U.S.C. 1681 et seq.). Do not use it for credit, insurance, employment, housing or tenant-eligibility decisions about any person without independently verifying the underlying record and obtaining legal advice. Not legal, tax or investment advice.

Accuracy. Records may be incomplete, delayed, sealed, amended or removed by the issuing agency. Each register block carries its asOf; registersMissing lists registers that did not answer. Verify with the issuing agency before relying on any record.

Matching. Records are joined only by the exact Companies House number, or by a name that is identical after the documented normalisation. Names are never used to assert an identity beyond an exact-normalised match.

Personal data. Company-level only; no officers, PSC, trustees or individual names.

Corrections and removal. If a record is wrong, or you need a company suppressed, contact the publisher through the Apify actor's Issues tab; we forward verifiable correction and removal requests to the issuing agency and reply within 10 working days.
