How it works

2) Pick an outcome Refund / replacement / compensation / correction.
3) Send with confidence Clear structure, calm tone, next steps.

Tip: receipts, screenshots, order numbers, account references, and chat/call notes help — but you can still complain effectively without them.

Escalation and evidence

If you do not get a satisfactory response, you can escalate. The right route depends on the sector and whether the firm uses an ADR/ombudsman scheme.

  • Sector: banking
  • Regulator / ombudsman / ADR: Financial Ombudsman Service (FOS) for eligible UK consumer complaints
  • Typical wait before escalation: Allow up to 8 weeks for a final response before considering escalation (typical UK complaints timeframe).
  • Evidence that helps: Array

Your letter should request a written response and set a reasonable deadline.
