A strong insurance complaint is not simply a longer version of the claim history. It tells the complaints team what decision is challenged, why the reasoning is wrong, what evidence changes the analysis and what outcome you want.
If the claim has been rejected, Steve Smart’s expert guide covers the full route from refusal through evidence and escalation. This companion guide focuses specifically on turning that dispute into a formal complaint or rebuttal.
Use a four-part complaint structure
- Decision: state the claim decision or handling failure you are challenging.
- Error: identify the factual, policy, evidential or procedural error.
- Evidence: point to the material that proves or supports your position.
- Remedy: say exactly what you want the insurer to do.
Make clear that it is a complaint
If you want the regulated complaint process to start, say so. Put “Formal complaint” in the subject line or opening and identify the claim reference. This helps separate complaint handling from ordinary claim-chasing correspondence.
For most ordinary complaints, the FCA DISP rules require the firm to send the prescribed final or other written response within eight weeks.
Answer the insurer’s reason point by point
Do not argue with a different case from the one the insurer actually made. Quote or summarise the critical proposition, then answer it with the policy wording and evidence.
| Weak complaint | Stronger approach |
|---|---|
| “This is unfair and I have been a customer for years.” | “The refusal relies on exclusion X. The engineer’s report does not identify evidence that X caused the damage; photograph Y and the repair record show Z.” |
| “Please reconsider.” | “Please withdraw the refusal and reassess the claim under section Y of the policy, or explain the evidence supporting each element of the exclusion.” |
Separate claim merits from service failures
If the insurer both rejected the claim and handled it badly, use separate headings. One part should challenge the coverage or settlement decision. Another can address avoidable delay, missed appointments, poor communication or failure to provide information.
This makes it easier to ask for different remedies: payment or reassessment of the claim on one hand, and compensation or service redress for handling failures on the other.
Use regulatory rules carefully
ICOBS 8.1.1R requires insurers to handle claims promptly and fairly, provide reasonable guidance and progress information, avoid unreasonable rejection and settle promptly once terms are agreed. Cite it where it connects to the actual complaint rather than adding regulatory references as decoration.
Quantify the remedy where you can
If you say the cash settlement is too low, give the calculation or quotations. If a delay caused additional expense, list the amount and evidence. If you want the insurer to arrange repair rather than make a cash payment, say so.
A complaint is easier to resolve when the business can see what outcome would settle it.
Protect the Financial Ombudsman route
If you receive a final response and remain dissatisfied, check FOS eligibility and the referral deadline immediately. The normal rule is six months from the date of a valid final response. Continuing to correspond with the insurer does not safely suspend that period.
