Car Insurance Disputes: How to Dispute a Claim, Settlement, or Payout in the UK

Introduction

Car insurance dispute problems are becoming more common. Policies can be rejected for small mistakes, settlements may not cover your losses and liability decisions can feel unjust. Understanding how the car insurance claim dispute process works in the UK helps you secure a fair outcome.

This guide explains how to challenge a rejected or underpaid claim, how to dispute a settlement or write‑off valuation, and what to do when a claim is made against you. It follows the regulatory timelines; insurers usually have eight weeks to respond to complaints, and consumers then have six months from the final response to go to the Financial Ombudsman Service (FOS).

Can You Dispute a Car Insurance Claim in the UK?

Yes. You can dispute a car insurance claim by using your insurer’s complaint procedure and, if needed, referring the matter to the FOS. When an insurer rejects, delays or underpays your claim, start by checking your policy and the reason for refusal. Submit a written complaint with evidence. If the insurer doesn’t resolve the complaint within eight weeks or you’re unhappy with the final response, you usually have six months from the date of that response to take the issue to the FOS.

The same process applies if you’re disputing a car insurance settlement or payout or arguing over liability. The FOS can review evidence from both sides and may tell the insurer to adjust the offer or apologise.

What Counts as a Car Insurance Dispute?

A car insurance dispute covers any disagreement over a motor policy. Typical categories include:

• Claim rejected or voided: the insurer refuses to pay anything because they believe the claim falls outside the policy terms, or because of non‑disclosure or misrepresentation.
• Claim underpaid or delayed: the insurer accepts the claim but offers a low settlement offer or delays payment.
• Settlement or payout disagreement: you accept liability but dispute the amount offered for repairs, hire car costs, or deductions.
• Total loss or write‑off valuation dispute: the insurer declares the vehicle a total loss and offers a sum you think is too low.
• Liability or fault dispute: someone makes a car accident insurance dispute against you, and you disagree with the insurer’s fault/liability decision.

Each dispute type follows similar complaint steps but may require different evidence. The next sections explain the reasons insurers reject or reduce claims and how to challenge them.

Common Reasons Insurers Reject or Reduce Payouts

Many rejections relate to information and process rather than fraud. Insurers may refuse or reduce claims because of:

• Incorrect information: incomplete or inaccurate details about the incident or your car can lead to rejection.
• Failure to take reasonable care: policies require you to prevent losses; leaving valuables on display or not securing the vehicle may breach this duty.
• Omissions or inaccuracies in application: not disclosing material facts (such as convictions or modifications) can invalidate the policy.
• Technical sticking points: insurers might rely on small‑print exclusions, such as using a car for business when only personal use is covered.
• Process mistakes: failing to follow the claim procedure or reporting late can allow insurers to reject a claim.
• Underinsurance: if your policy limits do not cover the full loss, the insurer may pay only part of the claim.

When you receive a rejected car insurance claim or a low settlement offer, review the policy wording. Under the Consumer Insurance (Disclosure and Representations) Act 2012, which came into force in April 2013, insurers cannot reject a claim if you took reasonable care to answer questions honestly. The Act abolished the previous duty to volunteer material information and replaced it with a duty to take reasonable care not to make a misrepresentation when answering the insurer’s questions

The Car Insurance Claim Dispute Process (Step‑by‑Step)

Challenging an insurance decision requires a clear process. Use the following steps to build your evidence pack, prepare your complaint letter and maintain a chronology. CaseCraft.AI can automate much of this work.

1. Check Your Policy and Reasons for Refusal

• Read the insurer’s letter carefully. Highlight the policy clause they rely on and compare it with your circumstances.
• Note any ambiguous wording or missing questions. If the insurer is relying on information you were never asked to provide, record this for your complaint.
• Gather documents: policy schedule, renewal notices, correspondence and call notes.

2. Request Evidence Used by the Insurer

Ask for any reports, valuations, engineer assessments or adjuster notes the insurer relied on. For write‑offs, ask how they arrived at the valuation and whether they used valuation guides or adverts.

3. Draft a Formal Complaint Letter

• Mark your letter “Complaint” and include your name, policy number and claim reference.
• Explain why you think the decision is wrong, referring to policy wording and evidence.
• State what outcome you want (e.g., full settlement, higher valuation) and give a reasonable deadline for response.
• Mention that you will refer the matter to the FOS if it isn’t resolved.
  Attach copies of your evidence pack and keep originals safe.

4. Follow the Insurer’s Complaints Procedure

Send your complaint to the address given in the insurer’s complaints procedure. Keep a record of when it was sent and any replies. Insurers typically have eight weeks to issue a final response letter. During this time, they may request more information; respond promptly.

5. Escalate to the Financial Ombudsman Service (FOS)

If you don’t receive a final response within eight weeks or you’re unhappy with the outcome, you can take your case to the FOS. You must do this within six months of the final response date. The FOS is independent and free. It will look at both sides’ evidence and can tell the insurer to adjust the settlement, apologise or pay compensation.

Disputing a Car Insurance Claim Against You (Liability Disputes)?

Being blamed for an accident can affect your no‑claims discount and premiums. When someone makes a claim against you, insurers decide liability by looking at negligence and the duty of care each driver owes. A driver can be negligent for speeding, running red lights, tailgating or using a mobile phone. External factors such as poor road conditions or mechanical failure may also contribute.

What to Do Immediately After an Accident?

• Stay safe and report the incident. Ensure everyone is safe and call emergency services if needed. If police attend, note the reference number and obtain their report.
• Exchange details with other drivers: names, addresses, phone numbers and insurers. Do not discuss fault at the scene.
• Collect evidence: take wide and close‑up photos of vehicle positions, damage, road signs and road conditions. Get contact details for independent witnesses and save any dash‑cam footage.
• Make notes: write down time, location, weather and what was said. Memories fade quickly.
• Contact your insurer promptly and provide factual information.

Challenging a Liability Decision

Insurers may decide fault based on statements, vehicle damage, Highway Code rules and case law. If the decision seems unfair:

• Highlight factual errors: correct mistakes in timelines, road layouts or witness statements.
• Submit extra evidence: photographs, dash‑cam clips, CCTV, engineer reports or witness statements can challenge the insurer’s narrative.
• Understand shared liability: in some cases, liability is split (for example, 50/50 or 70/30). Accepting partial responsibility may still reduce your premium impact.
• Use the official injury claim portal for injury claims: compensators usually have 30 business days to decide liability (40 days if the Motor Insurers’ Bureau is involved). If they miss this deadline, liability is automatically accepted. You can challenge denial three times before going to court.
• Escalate to the FOS if the insurer’s final response still seems wrong and you have evidence to support your position.

Can You Dispute a Car Insurance Settlement or Payout?

Yes. If you think the settlement doesn’t cover your losses, challenge it. Common issues include:

• Repair quality or cost: if the insurer’s approved repairer provides poor workmanship or uses non‑original parts, you can request another estimate or insist on quality repairs.
• Hire car and loss‑of‑use costs: insurers often cap hire periods. Provide evidence of reasonable expenses and proof that you needed the hire car for work or family commitments.
• Excess and deductions: insurers may deduct an excess or account for betterment (where repairs leave your vehicle in better condition). Ask for a breakdown and check whether deductions comply with the policy.
• Partial offers: some letters use language like “final offer” even before the complaint process is finished. Remind the insurer that you will consider it a final response only when they confirm it in writing.

If negotiation fails, gather independent quotes and valuations. Remember, you can still refer the dispute to the FOS within six months.

Car Insurance Valuation Dispute (Write‑Off /Total‑Loss Offers)

When your car is written off, insurers must pay its market value, the price it would have sold for just before the incident. Many complaints arise when the insurer’s offer is lower than expected. The FOS explains that it checks specialist valuation guides and other evidence to decide if an insurer’s figure is fair. If valuation guides differ, the FOS looks at adverts or expert opinions.

Building Your Valuation Challenge

• Consult valuation guides: look up your car’s make, model, age and mileage in guides such as Glass’s or CAP. Print or save the results.
• Gather comparable adverts: find three similar cars (same age, mileage and condition) listed for sale at higher prices. Provide screenshots with dates.
• Consider modifications and extras: most modifications (e.g., sat‑navs, exhausts) don’t significantly increase market value. Only high‑quality accessories or agreed‑value policies will count.
• Account for left‑hand drive or imports: insurers may deduct value for left‑hand‑drive or imported vehicles; they should supply evidence to justify the deduction.
• Check vehicle condition: insurers can reduce value for pre‑existing damage or lack of roadworthiness. The FOS reviews the engineer’s reports to ensure deductions are fair.
• Salvage rights: after a write‑off, the insurer usually owns the salvage. If you want to keep the car, tell the insurer before accepting payment. The insurer can deduct the salvage value, but it must show evidence of the deduction.
• New car replacement: some policies offer a like‑for‑like replacement if the car is written off within a set time and repair costs exceed 60–70% of the list price. Check the policy terms.

Present your evidence pack and ask the insurer to revise the offer. If they refuse, the FOS may order them to adjust the valuation to the highest guide price or the most credible evidence.

Going to the Financial Ombudsman Service (FOS): Timelines and What to Expect?

The FOS is an independent body that resolves complaints between consumers and financial businesses. It’s free to use and can make legally binding decisions on insurers.

• Start with the insurer: you must complain to your insurer first and wait for a final response or the end of the eight‑week period.
• Refer within six months: once you have the final response, you have six months to lodge your complaint with the FOS.
• Provide your evidence pack: send the FOS your complaint letter, policy documents, valuations, photos and any correspondence.
• Expect a review: the FOS will review your case, ask questions and may mediate a settlement. It will consider whether the insurer followed the policy terms and acted fairly.
• Binding decision: if the FOS upholds your complaint, the insurer must follow its decision. The FOS can tell the insurer to pay the correct settlement, add interest, cover additional costs or apologise.
• Time to resolve: complex cases may take several months. The FOS publishes indicative timescales on its website and will keep you updated.

When to Speak to Car Insurance Dispute Solicitors and What They Will Need?

Legal advice may be appropriate when:

• The claim is high‑value or involves serious injury or fatality.
• The insurer alleges fraud, misrepresentation or policy avoidance.
• Liability is complex (multi‑vehicle accidents, disputed right of way, conflicting evidence).
• You have already exhausted the FOS process and need to take court action.

Solicitors will ask for:

• Your policy documents and any endorsements.
• A chronology of events and a copy of your complaint letter and final response letter.
• An evidence pack (photos, witness statements, dash‑cam clips, engineer reports, valuations).
• Proof of financial losses (repair invoices, hire car costs, receipts).

How to Reduce the Risk of Future Disputes?

• Disclose everything: always answer application and renewal questions truthfully. List modifications, convictions and any changes in use.
• Maintain your vehicle: keep up with servicing and MOTs; insurers may reduce payouts if a car isn’t roadworthy.
• Keep records: store receipts for repairs and upgrades, photographs of your car’s condition and proof of regular maintenance.
• Report incidents promptly: contact your insurer as soon as possible after any accident or theft.
• Follow the claims process: provide accurate information and respond quickly to requests.
• Confirm agreements in writing: after phone calls, email the insurer summarising what was agreed and ask them to acknowledge.

Next Steps
