Revolut is an e-money company that offers digital banking services, but not a UK bank, though it has applied for a UK banking licence. Consequently it presently isn't part of the UK Financial Services Compensation Scheme (FSCS) which would guarantee savings up to £85,000 nor has it signed up to the UK Contingent Reimbursement Model Scheme (CRM) which reimburses victims of authorized push payment fraud.
Both Monzo and Starling are registered UK banks, so unlike Revolut, covered by both the FSCS and the CRM.
Wise is not a bank and doesn't claim to be, it is a simply a peer to peer money transfer company.
