Complete Guide to Bank Disputes, APP Fraud & FOS Complaints

If you have been defrauded, sent money to a scam, or your bank refused to help, you have legal rights. This guide explains APP fraud claims, chargebacks, and how to escalate to the Financial Ombudsman.

Key fact: Banks are now required to refund APP fraud victims (Authorised Push Payment scams) unless you were negligent. You can escalate to the FOS if your bank refuses.

What is APP fraud and bank fraud?

APP fraud occurs when criminals trick you into authorising a transfer to their account by impersonating a trusted person or organisation. Unlike card fraud, the money leaves your account with your consent - but obtained by deception. Banks historically refused refunds, but new rules require them to compensate victims.

Your rights under UK law

Step-by-step how to claim

  1. Report to your bank immediately. Call and provide all details of the fraudulent transaction.
  2. File a police report. Get the reference number - banks require this.
  3. Request a refund formally. Write to your bank citing the Payment Services Regulations 2017.
  4. If the bank refuses, escalate to FOS. The Financial Ombudsman can order them to refund you.
  5. If the FOS rejects your claim, consider legal action. In some cases, banks have been forced to pay by courts.

Common scenarios

Scenario 1: You received a call from "your bank" asking you to transfer money

This is a common scam. Banks never ask you to authorise transfers in this way. Report immediately to your bank and police. Under the new rules, the bank may refund you unless you ignored obvious warnings.

Scenario 2: You sent money to what you thought was a trusted business

If you can prove you were deceived (fake email domain, forged invoice, impersonation), the bank should refund under APP fraud rules.

Scenario 3: Bank delayed processing - money went to scammer instead

If your bank delayed a transaction and you lose money as a result, they may be liable for negligence.

Key deadlines

Escalation options
