Why escalation works — and where firms stall
UK financial-services firms regulated by the FCA must follow specified complaint-handling rules (DISP). A complaint moves through three stages: (1) the firm's internal team, (2) a final response from the firm (or 8 weeks elapsing, whichever is sooner), (3) the Financial Ombudsman Service (FOS). Most stalling happens at stage 2 — firms know that around 40% of customers give up before reaching FOS. The escalation planner exists to make that path mechanical so you don't drop out at the worst moment.
The Financial Ombudsman Service route
Once you have the firm's "final response" letter (which must say it's final and reference FOS), you have 6 months to escalate to FOS. FOS is free for consumers, the decision is binding on the firm if you accept it (up to award limits — currently £415,000 for complaints about acts after 1 April 2023), and the firm cannot retaliate against you for using it. FOS publishes outcome data — many firms have higher-than-average rates of being told to compensate customers, and that publicity is one reason many complaints settle at stage 2.
What evidence to keep from the start
From the moment you suspect a problem: dated screenshots of online statements or transactions, call notes with the agent's name and reference number, written confirmations of any verbal promises, and copies of all letters including envelopes (postmarks matter for time-limit disputes). If a firm refuses to confirm something in writing, that itself is evidence — request it again by email, and the unanswered email becomes part of the file.
When FOS isn't the right route
FOS only covers FCA-regulated firms and certain consumer disputes. Energy disputes go to Ombudsman Services: Energy; communications and broadband to Ombudsman Services: Communications or CISAS; housing disputes to the Housing Ombudsman; pension-scheme administration to The Pensions Ombudsman. Use the correct ombudsman first time — submitting to the wrong scheme wastes weeks.
