Context

The UK's Companies House registers more than 5 million companies and was long criticised as a 'self-certification' register vulnerable to shell-company abuse. The Economic Crime and Corporate Transparency Act (ECCTA) 2023 gave it new verification and enforcement powers, and in November 2023 Companies House became the first government user of Quantexa's Single Network Analytics Platform (SNAP), a graph-based machine-learning entity-resolution tool built with the Public Sector Fraud Authority.

Activities

The SNAP 2 upgrade added datasets covering 18,000 UK/US-sanctioned entities, 1,000 World Bank-debarred entities and 647,000 dormant UK companies, helping analysts spot shell-company networks and hidden beneficial owners.

Results

Between the Act's identity-verification rules taking effect in November 2025 and June 2026, nearly 4 million directors and persons of significant control verified their identity via GOV.UK One Login, and Companies House removed roughly 151,000 registered-office addresses used fraudulently since March 2024, with 920 companies referred for expedited strike-off.

Conclusions

Government reporting attributes these totals to the combined effect of new statutory powers, identity verification and data analytics; it does not isolate how many detections are directly attributable to the AI/network-analytics layer, and Quantexa's underlying models are not independently published.

Implementation
Indicative cost
High (€500k–€5M) — National platform contract with Quantexa plus legislative and identity-verification infrastructure (GOV.UK One Login); no public contract value found.
Time to results
Medium (1–3 years) — Deployed November 2023, expanded via SNAP 2 and a phased identity-verification rollout from November 2025 to June 2026.
Staffing & skills
Quantexa (platform vendor), UK Public Sector Fraud Authority / Companies House analytics and enforcement teams
