CompanyBeacon

Methodology and limitations

How CompanyBeacon resolves company identity, separates source dates and avoids turning public-record signals into unsupported conclusions.

Identity first

Companies House number is the canonical company key. Names are labels that can change. Fund membership is associated with that number where a public source or curated resolution supplied it. A GLEIF link is published only when registration authority RA000585 carries the exact same Companies House number; name-only matches are rejected.

Source hierarchy

  1. Current Companies House proxy response or daily CompanyBeacon snapshot.
  2. Official public-record D1 projection with recorded import metadata.
  3. Governed R2 analytical projection or immutable source snapshot with explicit licence, identity rule and source date.
  4. Curated fund-membership snapshot with its source last-modified date.

Publication boundary

Storage possession is not publication permission. Public pages use only source families whose recorded terms permit commercial use and derivatives, and only for the approved fields shown in the licence register. Raw officer, PSC, address and date-of-birth records, private accounts, affiliate data and gated research payloads are not republished. Ownership and governance sections link to the authoritative register instead.

Daily refresh

A scheduled Cloudflare queue submits every tracked company number for rechecking. Consumers update the dedicated status database at a rate designed to respect the upstream API and also refresh the 294 exactly matched GLEIF records. A later scheduled job writes an aggregate JSON report to R2.

National indicators

UK context reports read the newest immutable parsed R2 snapshot. Each monthly, quarterly, weekly or on-change observation keeps its own period. A new page render never relabels an older official observation as today's value.

What we do not infer

A company status does not prove investment performance, misconduct, tax eligibility or the current holdings of a fund. An LEI or LEI renewal status is not a credit or solvency signal. National statistics do not predict an individual company. Contract awards do not prove total supplier revenue. Charity-company matches use published identifiers and should be verified at source.
