FCA Firm Checker — how to verify a crypto company
Quick answer: Search firm name on fca.org.uk/firms/firm-search. Check permissions include 'cryptoasset' activities. MLR-registered only ≠ fully authorised until October 2027 regime. Avoid firms not on the register. Firm Checker shows warnings and cancelled firms.
The FCA Firm Checker is the public search tool for authorised firms. After June 2026 landmark rules, understanding the difference between MLR registration and full authorisation matters more than ever.
Firm Checker vs Register
Firm Checker (fca.org.uk/firms/firm-search) gives a simplified view — good for quick checks. Financial Services Register shows full permission schedule, approved persons, and regulatory history. Use both before large transfers.
What to look for on a crypto exchange
Search exact legal entity name from terms of service. Confirm 'Cryptoasset exchange provider' or custodian permissions. Note registration date. Read any supervisory notices.
Warning list and clones
FCA Warning List flags unauthorised firms. Clone scams use fake websites copying authorised FRNs. Always navigate to the firm via FCA register link, not Google ads.
If a firm is not listed
Do not send money. Report to FCA consumer helpline. Overseas firms marketing to UK without approval may breach financial promotions rules.
