A vague, frustrated complaint is easy for an insurer to deprioritise. A structured one, with references and evidence attached, is much harder to sit on.
Structure the complaint clearly
State your policy number and claim number at the top, describe exactly what happened and what you're unhappy about, and be explicit about the outcome you want — a specific payment, a decision reviewed, or a written explanation. A complaint that ends with a clear ask is easier to act on than one that just describes frustration.
Keep every reference number
Note your policy number, claim number, and — once you complain formally — your complaint reference number. If the insurer assigns a specific case handler, keep their name too; it makes every follow-up faster.
Save correspondence as you go
Keep copies of everything you send and receive, and log the date and a short summary of every phone call, including who you spoke to. If a call includes a promise or a deadline, follow it up in writing ("just confirming what we discussed on the call...") so there's a written record even of verbal conversations.
Give the insurer a fair chance to respond first
UK insurers must generally issue a final response to a complaint within 8 weeks. Escalating before that window has passed, without at least one clear written complaint on record, makes it harder to demonstrate you gave the insurer a genuine opportunity to resolve things.
When to escalate
If the 8-week window passes with no final response, or you're not satisfied with the response you do get, you can refer the complaint to the Financial Ombudsman Service free of charge. Have your complaint reference number and copies of all correspondence ready — FOS will want the full history, not just the final response.
