How a financial complaint should progress
Send a clear complaint first and keep a copy of the final response or the date the complaint was made.
Complain to the firm first
Give account details, amounts, dates, evidence and the outcome requested.
Wait for a final response
Most financial firms have up to eight weeks to issue a final response to a complaint.
Escalate if unresolved
If unresolved after the final response or relevant deadline, consider the Financial Ombudsman Service if the issue is in scope.
Do not delay if a deadline is stated in a final response letter.
