What to Do If Your Car Insurance Claim Is Disputed UK 2026

What "disputed" means in UK motor insurance

A motor insurance claim becomes "disputed" when the policyholder and the insurer disagree on whether the claim is payable, on the amount of the payout, on the allocation of liability between the parties involved, or on the conduct of the claims process itself. The FCA's Insurance Conduct of Business Sourcebook (ICOBS) chapter 8, on claims handling, imposes a set of duties on the insurer: to handle the claim promptly and fairly, to provide reasonable guidance to the policyholder, to settle claims promptly once liability is established, and not to refuse a claim unreasonably. A breach of any of those duties is itself a separate ground for a complaint, even if the underlying liability dispute is unresolved.

The Consumer Duty, brought into force across UK financial services through PRIN 2A in 2023, layers an additional fairness expectation over the ICOBS rules. The Consumer Duty requires the insurer to deliver good outcomes to retail customers, to avoid foreseeable harm, and to support customers in achieving their financial objectives. The Duty has shifted the FOS approach in disputed claims: an insurer that technically complied with the policy wording but failed to deliver a good outcome to the customer can now be ordered to make additional payments under the Consumer Duty even where the contract terms favoured the insurer.

The most disputed grounds and what they look like in practice

Five grounds account for the majority of disputed motor insurance claims in the UK. The first is total-loss valuation: the insurer's appointed engineer values the vehicle at one figure, the policyholder believes the market value is higher, and the difference is in the high hundreds or low thousands of pounds. The dispute is usually resolved by the policyholder producing three independent market valuations from forecourt listings, dealer quotes, or trade valuation services.

The second is liability allocation in disputed-fault collisions. Two drivers each blame the other; the insurers negotiate; the result is often a 50/50 split for lack of better evidence. The dispute is usually resolved by producing dashcam footage, independent witness statements, or police accident reports. The third is policy exclusions: the insurer cites a specific exclusion in the policy wording (driving in commerce, driving while uninsured under another policy, driving an off-road vehicle, named-driver-only on a telematics policy) and refuses the claim. The dispute is usually resolved by interpreting the exclusion against the factual circumstances.

The fourth is alleged non-disclosure under the Consumer Insurance (Disclosure and Representations) Act 2012. The insurer refuses the claim on the basis that the policyholder misrepresented a material fact at inception or renewal. The dispute is usually resolved by examining the application form against the actual facts and applying the proportionate-remedy framework. The fifth is alleged fraud. The insurer suspects the claim is exaggerated, staged, or duplicated. The dispute is usually resolved through documentary and behavioural evidence on both sides.

Step one: the insurer's internal complaints process

The first step in any UK motor insurance dispute is the insurer's internal complaints process. This is mandatory under FCA rules: a consumer cannot take a complaint to the Financial Ombudsman Service until the insurer has either issued a final response or had 8 weeks to do so. The complaint should be lodged in writing (email or letter, both keep an audit trail), should set out the dispute, the evidence, and the outcome the policyholder is seeking, and should reference the policy number and the claim reference.

The insurer must acknowledge the complaint within 5 working days under DISP 1 of the FCA Handbook. The insurer then has 8 weeks to issue a final response. The final response must be in writing, must address each point raised, must explain the insurer's position and the evidence supporting it, and must include a "right to refer" statement informing the policyholder of the right to escalate to the Financial Ombudsman Service.

If the insurer has not issued a final response within 8 weeks, the policyholder can escalate to the FOS on the strength of that delay alone, without waiting further. The 8-week deadline is a hard date, not a soft target, and FOS routinely accepts complaints brought on its expiry.

Step two: the Financial Ombudsman Service

The Financial Ombudsman Service is the statutory independent dispute resolution body for UK financial services, including motor insurance. The service is free to the consumer; the insurer pays a case fee on each complaint accepted. The FOS receives the complaint, requests the insurer's file, reviews the evidence on both sides, asks for additional information where needed, and issues a decision. The decision is binding on the insurer if the policyholder accepts it; if the policyholder rejects it, the policyholder retains the right to litigate in the courts.

The FOS binding award limit for the 2025-26 award year is GBP 430,000 for complaints about acts or omissions on or after 1 April 2019. The figure is higher than any individual motor insurance claim is likely to exceed, so the FOS award limit is rarely a constraint in practice.

A FOS complaint must be brought within 6 months of the insurer's final response, and in any event within 6 years of the event complained of, or within 3 years of when the policyholder became aware (or ought reasonably to have become aware) of the cause for complaint. The 6-month deadline from the final response is the most commonly missed limit.

Evidence to gather and how to present it

The evidence base that wins a UK motor insurance dispute falls into five categories. The first is contemporaneous documentation: the police accident report number where applicable, photographs of the scene taken on the day, photographs of the damage to all vehicles, contact details of every witness, and a written statement from the policyholder dated within 48 hours of the incident. The second is dashcam footage, downloaded from the device within 24 hours of the incident and stored on a separate device or cloud account. Dashcam footage is the single most influential piece of evidence in liability disputes.

The third is market evidence for valuation disputes: three independent valuations from forecourt listings (AutoTrader, eBay Motors, Car Gurus), a dealer-quoted trade-in value, and a trade valuation reference such as Glass's Guide or CAP. The fourth is medical evidence for personal injury claims: GP records, hospital discharge letters, physiotherapy notes, and time-off-work confirmations. The fifth is the insurer's own correspondence: every letter, every email, and a contemporaneous diary noting the date, time, and substance of every phone call, with the name of the call handler where given.

The presentation matters as much as the content. A FOS complaint that arrives as a structured chronology with documents attached and labelled is reviewed differently from a free-form narrative that the case handler has to reconstruct. The most useful structure is a date-ordered chronology, with each entry citing the underlying document by reference.

Time limits: 6 years contract, 3 years personal injury, 6 months FOS

Statutory time limits constrain every disputed claim. Insurance claims as contract claims under English and Welsh law are time-barred 6 years after the breach under section 5 of the Limitation Act 1980. The clock typically runs from the date the insurer refused the claim or issued a partial payment. Scotland uses a 5-year prescription under the Prescription and Limitation (Scotland) Act 1973. Personal injury claims are time-barred 3 years after the injury date (or the date of knowledge of the injury, whichever is later) under section 11 of the Limitation Act 1980.

The FOS 6-month deadline from the insurer's final response is shorter than any of these and is the most frequently encountered constraint. A policyholder who sits on a final response for more than 6 months loses the FOS route and has only the courts left. The courts are open until the underlying limitation period expires, but the courts are slower, more expensive, and procedurally more demanding than the FOS.

What this means in practice

Consider a 46-year-old policyholder in Glasgow whose 2018 Ford Focus is written off in a no-fault collision on 1 February 2026. The insurer's engineer values the vehicle at GBP 4,200. The policyholder, who recently insured the vehicle on a stated-value basis, believes the market value is closer to GBP 5,800 based on AutoTrader listings for comparable mileage and condition. The policyholder lodges a written complaint with the insurer on 15 February 2026, attaching three AutoTrader screenshots showing comparable listings at GBP 5,650, GBP 5,800, and GBP 5,950. The insurer acknowledges within 5 working days and issues a final response on 8 April 2026, offering GBP 4,600. The policyholder rejects the final response and escalates to the FOS on 22 April 2026. The FOS reviews the evidence over the next 12 weeks and issues a decision on 18 July 2026 ordering the insurer to pay GBP 5,400 plus interest at 8% from 1 February 2026 to settlement. The insurer pays on 5 August 2026. Total time elapsed: just over 6 months; total uplift on the original offer: GBP 1,200.

How we verified this

The insurer's claim-handling duties sit in the FCA's Insurance Conduct of Business Sourcebook (ICOBS), chapter 8, and the wider Consumer Duty in Principle 12 and PRIN 2A, accessible through the FCA Handbook at fca.org.uk. The complaints-handling rules sit in DISP 1. The Financial Ombudsman Service binding award limit of GBP 430,000 for the 2025-26 award year is published at financial-ombudsman.org.uk. The statutory limitation periods sit in section 5 (contract) and section 11 (personal injury) of the Limitation Act 1980 on legislation.gov.uk, with the Scottish equivalent in the Prescription and Limitation (Scotland) Act 1973. The disclosure framework that governs many alleged-non-disclosure disputes is the Consumer Insurance (Disclosure and Representations) Act 2012 on legislation.gov.uk.

Frequently Asked Questions

What do I do first if my car insurance claim is refused?

Lodge a written complaint with the insurer through the published complaints route. The complaint should set out the dispute, the evidence, and the outcome you want. The insurer must acknowledge the complaint within 5 working days under FCA DISP rules and must issue a final response within 8 weeks. Keep every email and letter.

Can I take my insurer to the Financial Ombudsman Service?

Yes, after the insurer has either issued a final response or had 8 weeks to do so. The FOS service is free to the consumer. A complaint must be brought within 6 months of the final response. The FOS can issue a binding award up to GBP 430,000 in the 2025-26 award year.

How long does the Financial Ombudsman Service take?

Most motor insurance complaints are resolved within 4 to 6 months of being accepted, though complex cases can take longer. The FOS publishes its current case-handling times on its website. A simple total-loss valuation dispute is often resolved in 8 to 12 weeks; a complex liability dispute can take 6 to 12 months.

What evidence do I need to dispute a total-loss valuation?

Three independent market valuations from forecourt listings, a dealer trade-in quote, and a trade valuation reference such as Glass's Guide or CAP. The valuations should be for comparable vehicles by make, model, year, mileage, and condition, captured within the same week as the insurer's engineer report.

Can the insurer refuse my claim if I forgot to declare something?

It depends on whether the non-disclosure was deliberate, reckless, or careless under the Consumer Insurance (Disclosure and Representations) Act 2012. A deliberate or reckless non-disclosure lets the insurer void the policy and refuse the claim. A careless non-disclosure produces a proportionate remedy: the claim is paid in proportion to the underdeclared premium, or refused only if the insurer would not have written the policy at all on the true facts.

What are the time limits for a UK motor insurance dispute?

6 years for contract claims under section 5 of the Limitation Act 1980 (5 years in Scotland under the Prescription and Limitation (Scotland) Act 1973), 3 years for personal injury claims under section 11 of the Limitation Act 1980, and 6 months from the insurer's final response to bring a complaint to the Financial Ombudsman Service. The 6-month FOS deadline is the most frequently encountered constraint.
