Companies House V4 Forensic Intelligence

Executive narrative

May 2026 public briefing summarising Companies House review-priority indicators. The public site is redacted and pseudonymised; it is intended for research and triage, not allegations, credit decisions, investment advice or legal findings.

Risk populations

• 5,168,399 active companies in the current public universe.
• 3,693,966 records have one or more review-priority indicators.
• 141,069 companies are flagged as at-risk within the public current screen.
• 6,878 high-risk and 35 critical-risk records are retained for controlled review.

Industry and filing themes

• The largest SIC concentrations include real estate, property trading, management consultancy and business-support activities.
• A material subset of companies have no SIC supplied, which remains a quality-control and interpretation issue.
• Accounts and confirmation-statement timeliness remain central review-priority signals.

Geographic concentration

• The strongest registration clusters remain concentrated in London and other high-volume registered-office locations.
• Public reporting should continue to use aggregate address clusters and postcode districts rather than naming individual companies in risk context.
• Protected operational dashboards retain fuller fields for authorised review.

Controls and provenance

• Monthly snapshots, source hashes, validation modules and archived artefacts are retained.
• Public payloads should expose pseudonymised companies and aggregated clusters only.
• Protected unredacted outputs remain separated under the access-controlled dashboard.
