When is the FCA Warning List updated?
The FCA updates the Warning List at its discretion based on consumer complaints, regulator referrals, and the FCA's own monitoring. There's no fixed schedule. In practice, multiple new entries appear most weeks; the FCA publishes a daily-refreshed CSV at https://www.fca.org.uk/consumers/warning-list.
The most common reasons for a firm appearing on the list:
1. **Consumer complaints triggering a perimeter check.** A consumer reports being defrauded by a firm claiming to be FCA-authorised; the FCA confirms the firm isn't authorised + adds it to the list.
2. **Clone-firm reports.** An authorised firm spots an unauthorised entity using its name, FRN, or branding to solicit clients. The clone gets added with a reference back to the legitimate firm.
3. **Cross-regulator referrals.** Action Fraud, the City of London Police, the Solicitors Regulation Authority, and other UK regulators refer matters to FCA when the underlying activity falls within FCA's perimeter.
4. **FCA's own monitoring.** Routine surveillance picks up firms operating without authorisation in regulated activities (investment advice, insurance distribution, mortgage mediation, etc).
For regulated UK firms, daily re-screening against the Warning List is the de-facto best practice. The Stratum FCA-warning-list endpoint pulls the FCA's published CSV nightly + indexes it for fuzzy-match retrieval, so a weekly diff against your monitored counterparty list catches any new appearances.
