SUPPLIER EVIDENCE GRAPH

What is linked—and how certain is the link?

Every relationship carries its source, date and match method. Exact identifier edges are observed; name-derived ownership or group paths remain inferred.

Exact GB-COH company number published on a Contracts Finder supplier record and resolved to the same register number.

CORPORATE GROUP / OWNERSHIPNot established

No exact corporate-parent edge established

The exact identity projection does not contain a publishable parent edge for this supplier. Absence is not evidence of independence.

FUNDING ROUNDSCoverage gap

No exact verified funding record linked

The held funding directory did not return a verified exact-company match. That does not prove the company has never raised capital.

SUPPLIER RISK & RENEWAL SIGNALS

Evidence first. Interpretation second.

These inputs help prioritise research; they do not rate supplier quality, solvency, integrity or future award prospects.

OBSERVED

Published and registered facts

OBSERVED EVIDENCE

2 published contract end dates in the next 24 months

1 fall within 12 months. End dates do not prove a reprocurement or renewal.

SourceContracts Finder daily award noticesDate15 Aug 2026Method

Exact supplier company number 01478540; date window applied to published contract_end fields.

INFERRED

Derived review signals

INFERRED · REVIEW SIGNAL

15% of linked notices name the leading buyer

Ministry of Justice appears on 2 of 13 linked notices. This is notice concentration, not revenue dependency.

SourceContracts Finder daily award noticesDate15 Aug 2026Method

Derived share = leading buyer notice count ÷ all exact-company-linked notices; values and contract delivery are not used.

INFERRED · REVIEW SIGNAL

1 near-term renewal research lead

A published end date is used only to prioritise source checks. It does not predict buyer intent, supplier retention or a future tender.

SourceContracts Finder daily award noticesDate15 Aug 2026Method

Derived from published contract end dates within 12 and 24 months of the current date.

No supplier risk score: Observed records and inferred review signals are never combined into a supplier risk score. Missing evidence is not a clean bill of health, proof of independence or proof that no funding or ownership relationship exists.
