A final response letter is the formal written response by a regulated firm to a complaint, setting out the firm’s investigation findings, decision, redress (if any) and the complainant’s right to escalate to the Financial Ombudsman Service.
The final response letter is the procedural milestone of DISP 1.6. It is the firm’s substantive answer to the complaint after investigation. It must be issued within eight weeks of receipt of the complaint (with a holding response required if not possible) and must comply with the prescribed content requirements.
The letter has compliance significance, customer-relationship significance and legal significance. It closes the firm’s internal complaint process; it triggers the six-month FOS clock; it forms part of the audit trail for any subsequent regulatory or judicial review.
DISP 1.6.2R requires the final response to:
DISP 1.6.4R requires the letter to be in writing. Most firms send electronically with a hard-copy follow-up where the complainant has not consented to electronic-only.
PRIN 2A (Consumer Duty) requires the response to be clear and accessible — using plain language, avoiding jargon, addressing the complainant’s specific concerns rather than generic templates.
PRA SMCR conduct rules impose individual responsibility on the senior manager for complaints to ensure the final response framework operates appropriately.
A well-drafted final response letter has a standard structure:
The tone matters. A well-written final response acknowledges the complainant’s experience, explains the firm’s view sympathetically, and (where there has been a failure) accepts responsibility cleanly. A poorly-written final response — defensive, formulaic or evasive — typically escalates rather than resolves.
For complex complaints, the final response may run to 6-10 pages with detailed sub-sections. For simple complaints, 1-2 pages may suffice. The length is driven by the complexity of the underlying issues, not by a desire to overwhelm the complainant.
The decision categories: “upheld” means the firm accepts the complaint in full; “partially upheld” means the firm accepts some elements; “rejected” means the firm does not accept the complaint. The complainant has full FOS rights regardless of the decision.
Operationally, final responses are reviewed before issue. Larger firms have a complaints quality team that reviews drafts for compliance with DISP, for tone, for accuracy and for completeness. Spot-checks are conducted by internal audit and (for very large firms) by external assurance providers.
A final response that does not comply with DISP requirements does not start the FOS six-month clock. If the complainant later goes to FOS, the FOS will treat the complaint as still within the eight-week firm-handling window and may direct the firm to re-issue a compliant response.
“Upheld” final response — complaint accepted in full; full redress offered.
“Partially upheld” final response — some elements accepted; partial redress.
“Rejected” final response — complaint not accepted; explanation provided.
“Goodwill” element — additional payment offered without admission of fault, where the firm wishes to maintain the relationship.
“Summary resolution communication” — a shorter response used under DISP 1.5 where resolution is reached within 3 working days.
A small business policyholder complained about delays in a commercial PI claim. The firm investigates and finds: the original handler had been overloaded; correspondence had been missed for periods of three to four weeks; the resulting overall delay was approximately six weeks beyond reasonable expectations; no substantive errors on the cover or quantum decisions.
Final response (six weeks after complaint receipt):
“Dear Mr X — we have completed our investigation into your complaint dated 15 February 2026 about the handling of claim ref. PI-2026-04123.
We thank you for raising your concerns. We acknowledge that you experienced delays in the handling of your claim and that several of your emails were not responded to within reasonable time. Our investigation has identified that the original handler on your file was managing an unusually high workload during the relevant period and that the supervisory checks that should have triggered escalation did not operate as designed.
We accept that we fell short of the service we should have provided. We have:
We have authorised a payment of £750 in compensation for the distress and inconvenience caused. This is in addition to any sums due under the policy. The payment will be processed within 5 working days.
We are sorry for the way your claim was handled. If you are not satisfied with our response, you can refer this matter to the Financial Ombudsman Service free of charge at [contact details]. You have 6 months from the date of this letter to do so.
[Senior manager signature and direct contact]”
The policyholder accepts the response and the goodwill payment is processed. The complaint is logged as upheld. Root-cause analysis informs the firm’s workload management improvements.
