Limitations

• Coverage varies significantly by jurisdiction

  Coverage varies significantly by jurisdiction — UK and EU have the best data; many countries have no public UBO register

• Data may lag real ownership changes

  Data may lag real ownership changes by months

• Complex ownership chains may not be fully resolved

  Complex ownership chains through multiple jurisdictions may not be fully resolved

• Currently covers UK companies only — more jurisdictions coming soon

  Currently covers UK companies only. Beneficial ownership data depends on company filings — some companies may not have filed PSC information

  What to do instead: For non-UK companies, use company-data capabilities for the relevant country and check local UBO registries

• PSC data is self-reported by companies to Companies House

  PSC data is self-reported by companies to Companies House. Accuracy depends on the filing company — data is not independently verified

  What to do instead: Cross-reference with other compliance data sources for high-value due diligence

• Companies listed on regulated markets are exempt from PSC filing requirements

  Companies listed on regulated markets (e.g. London Stock Exchange) are exempt from PSC filing requirements

  What to do instead: For listed companies, check shareholder registers and annual reports instead
