Car Insurance
When your motor claim is turned down: the rules, the rights and the route to the Ombudsman
Why insurers reject car claims, what the law actually allows them to refuse, and how to challenge a decision through the complaints process and the Financial Ombudsman Service.
TL;DR
An insurer must not unreasonably reject a claim under FCA rule ICOBS 8.1, and a refusal based on misrepresentation must follow the Consumer Insurance (Disclosure and Representations) Act 2012. Ask for the reason in writing, complain formally, and if the insurer's final response does not resolve it you can escalate free of charge to the Financial Ombudsman Service.

The most common reasons a car insurance claim is rejected
A rejection letter rarely arrives without a stated reason, and understanding the category of refusal is the first step in deciding whether to challenge it. The most frequent grounds fall into a handful of types: an exclusion in the policy wording, a breach of a policy condition, alleged misrepresentation at the point of sale, late or non-notification of the incident, and suspicion of fraud or exaggeration.
Exclusions are limits written into the contract, such as cover not applying when the car was being used for business if only social, domestic and pleasure use was declared, or damage caused while driving under the influence. Condition breaches include failing to maintain the vehicle in a roadworthy state, allowing an unnamed driver to use the car, or not reporting the incident in time. Misrepresentation covers situations where the answers given when buying or renewing the policy were inaccurate, for example an undeclared modification, a misstated occupation or an omitted conviction.
Each of these grounds is legitimate in principle, but only some justify a complete refusal. The crucial question is whether the insurer has applied the correct legal test, and in many cases challenged on that point the outcome changes from outright refusal to a reduced or proportionate settlement.
What the Consumer Insurance Act 2012 actually permits
The single most misunderstood area is non-disclosure and misrepresentation. Before 2013 an insurer could often void a policy and refuse a claim for almost any inaccuracy. The Consumer Insurance (Disclosure and Representations) Act 2012 replaced that harsh regime for consumer policies and abolished the old duty to volunteer information. Instead, the consumer must take reasonable care not to make a misrepresentation when answering the insurer's questions.
The Act then grades what happens when an answer is wrong. An honest and reasonable mistake gives the insurer no remedy at all: the claim must be paid. A careless misrepresentation gives a proportionate remedy, meaning the insurer is put in the position it would have been in had it known the truth. If it would still have offered cover but charged more, the claim is reduced proportionately rather than refused. Only a deliberate or reckless misrepresentation allows the insurer to void the policy, refuse all claims and keep the premium.
This grading matters enormously. A driver whose claim is refused outright for a careless error, such as understating annual mileage or forgetting a minor modification, may be entitled to a partial settlement rather than nothing. If the insurer has treated a careless mistake as if it were deliberate, that is a strong basis for challenge.
Step one: get the reason in writing and gather your evidence
Before complaining, ask the insurer to set out in writing the exact clause, condition or statement it is relying on and the legal basis for the decision. A vague refusal is harder to challenge than a specific one, and the FCA expects firms to give appropriate information about a claim decision. Request a copy of the statement of fact or proposal you completed when buying the policy, because that document shows precisely which questions were asked and how you answered.
Assemble your supporting evidence methodically. If the dispute is about a modification, gather any correspondence showing it was declared. If it concerns notification timing, find call records or emails proving when you reported the incident. If liability or the facts of the accident are disputed, photographs, witness statements and any police reference number are relevant.
Keep the tone factual and document everything. Note the names of staff you speak to and the dates of calls. A clear, evidenced account is far more persuasive than an emotional one, both to the insurer's complaints team and, if it gets that far, to the Ombudsman.
Step two: the formal complaint and the eight-week clock
Raising a formal complaint triggers protections under the FCA's Dispute Resolution: Complaints sourcebook, known as DISP. Once a complaint is made, the insurer must acknowledge it and investigate, and it has a maximum of eight weeks to issue a final response. That response should explain the firm's decision and tell you about your right to refer the matter to the Financial Ombudsman Service.
Make clear in your complaint that you are disputing the rejection, state the outcome you want, and reference the relevant law where you can, such as the proportionate remedy provisions of the 2012 Act. Put the complaint in writing so there is a record. If the insurer upholds your complaint, it should reinstate or settle the claim, sometimes with interest or compensation for the delay.
If the firm rejects the complaint or you receive no final response within eight weeks, the door to the Ombudsman opens. Do not let the insurer's refusal be the end of the matter simply because the letter sounds final; the complaints process and the Ombudsman exist precisely for these disputes.
Step three: escalating to the Financial Ombudsman Service
The Financial Ombudsman Service is an independent, statutory body that resolves disputes between consumers and financial firms at no cost to the consumer. You can refer a car insurance complaint to it once you have the insurer's final response, or once eight weeks have passed without one. You generally must refer within six months of the date of the final response, so do not delay.
The Ombudsman looks at what is fair and reasonable in the circumstances, taking account of the law, regulators' rules, codes of practice and good industry practice. It can direct the insurer to pay the claim in full or in part, to pay interest, and to compensate you for distress and inconvenience caused by unfair handling. If you accept the Ombudsman's final decision it becomes binding on the insurer.
Because the service publishes complaint volumes and uphold rates by individual firm, it offers a transparent picture of how insurers perform on disputes. A high uphold rate against a particular firm does not guarantee your outcome, but it underlines that rejection letters are frequently overturned when independently reviewed.

Frequently asked questions
Can an insurer refuse my claim for an honest mistake on my application?
No. Under the Consumer Insurance (Disclosure and Representations) Act 2012, an honest and reasonable misrepresentation gives the insurer no remedy, so the claim should be paid. Only careless mistakes allow a proportionate reduction, and only deliberate or reckless ones allow outright refusal.
How long does the Financial Ombudsman take to decide a car insurance dispute?
Timescales vary with complexity. Simpler cases may be resolved by an investigator's view in a few months, while contested cases that proceed to a final ombudsman decision take longer. The service prioritises cases and will give an indication once it assesses your complaint.
Does complaining cost me anything?
No. Complaining to your insurer is free, and the Financial Ombudsman Service is free to consumers. You do not need a solicitor or a claims management company to use either route, and using a paid representative would reduce any award you receive.
What if my policy was voided rather than just the claim refused?
Voiding treats the policy as if it never existed and usually only applies to deliberate or reckless misrepresentation. If your insurer has voided for a careless or honest error, that may be the wrong remedy, and it is a strong ground to complain and escalate to the Ombudsman.
Can I still drive while a claim or complaint is ongoing?
If your policy has been cancelled or voided you are no longer insured and must not drive that vehicle until you arrange replacement cover. A voidance can also affect future applications because insurers ask whether you have had a policy cancelled or voided, so disclose it accurately.
