Can I Claim on Someone Else’s Car Insurance?
Yes, you can claim directly on another driver’s car insurance if they were at fault for the accident. This is called a third-party claim, and it lets you recover costs for vehicle damage, medical expenses, and other losses without affecting your own no-claims discount.
Rather than claiming through your own car insurance and risking your NCD, you pursue the claim against the at-fault driver’s insurer. This works when the other driver clearly caused the accident and you have their insurance details.
If the other driver caused it, you can claim straight against their insurer rather than your own. That keeps your no-claims discount intact and avoids your excess entirely, which is the main reason to do it. If they turn out to be uninsured, the Motor Insurers’ Bureau takes their place. You have six years for property damage and three for injury.
Compare car insurance quotes and check what your own policy would have cost you.
What is a third-party claim?
A third-party claim is when you claim directly against the at-fault driver’s insurance policy, rather than claiming through your own.
How does it differ from claiming on your own policy?
| Third-party claim | Own-policy claim | |
| Who pays | Other driver’s insurer | Your insurer |
| Excess | None | Compulsory + voluntary |
| NCD impact | Not affected | May be affected |
| Speed | Can be slower | Usually faster |
| Control | You negotiate directly | Your insurer handles it |
With a third-party only policy, a third-party claim is your only route to recovering repair costs, since your own policy doesn’t cover damage to your vehicle.
What can you claim for in a third-party claim?
You can recover all reasonable costs resulting from the accident, including vehicle repairs, a hire car, medical expenses, and lost earnings.
What costs are recoverable?
- Vehicle repairs or write-off value: the cost of repairs at a competitive garage, or the car’s market value if it’s written off
- Hire car costs: a replacement vehicle of similar specification while yours is being repaired
- Medical expenses and personal injury: treatment costs, physiotherapy, and compensation for pain and suffering
- Lost earnings: income lost during recovery, supported by payslips and employer confirmation
- Additional expenses: taxi fares, recovery fees, and other costs directly caused by the accident
All costs must be evidenced and reasonable. The at-fault driver’s insurer may dispute claims they consider excessive or unrelated to the accident.
What about personal injury compensation?
Personal injury claims are handled separately from vehicle damage and can take significantly longer to settle. Minor whiplash claims typically settle for £1,000 to £5,000, while more serious injuries attract higher compensation.
You don’t need to accept the first offer from the at-fault driver’s insurer. If you believe the amount is too low, you can negotiate or instruct a solicitor to handle the claim.
How do you make a third-party claim?
Gather the other driver’s details at the scene, report the incident to your own insurer, then contact the at-fault driver’s insurer with your evidence.
What steps should you follow?
- Collect details at the scene: name, address, phone number, vehicle registration, insurer name, and policy number from the other driver
- Gather your own evidence: photographs of all damage, the scene, road markings, weather conditions, and dashcam footage if available
- Get witness details: names and contact information of anyone who saw the accident
- Report to your own insurer: this is a policy requirement even if you’re not claiming through them, and it doesn’t count as making a claim
- Contact the third-party insurer: submit your claim with all evidence, repair quotes, and a clear account of what happened
Keep copies of everything and maintain a written record of all correspondence. The more complete your submission, the faster your claim progresses.
What if the other driver won’t share their details?
Under the Road Traffic Act 1988, drivers involved in an accident must provide their name, address, and insurance details. Refusing is a criminal offence.
If they drive away, note their registration number and report the incident to the police. You can then trace their insurer through the Motor Insurance Database.
How does a third-party claim protect your no-claims discount?
Your no-claims discount stays intact because you’re not claiming through your own policy. The at-fault driver’s insurer pays out, so your claims-free record isn’t touched.
What if the other driver disputes fault?
If the other driver’s insurer disputes liability and argues you were partly responsible, your own insurer may become involved. In that case, your NCD could be at risk until liability is settled.
If you have comprehensive cover, you can claim through your own policy for faster repairs and let your insurer recover costs from the at-fault driver later. Your NCD is restored once fault is confirmed.
What if the other driver is uninsured?
If the other driver has no insurance, you can’t claim on their policy. Instead, claim through the Motor Insurers’ Bureau, which compensates victims of uninsured and untraced drivers in the UK.
How does the MIB process work?
The MIB is funded by all UK motor insurers and handles claims that can’t be directed at a specific insurer. The process takes longer than a standard third-party claim and has its own application requirements.
Alternatively, claim through your own comprehensive insurance for faster resolution. Your insurer may then pursue the uninsured driver to recover costs, though your NCD could be affected in the meantime.
Citizens Advice provides free guidance on your options if you’ve been hit by an uninsured driver, including how to apply to the MIB.
How long do you have to make a third-party claim?
Under the Limitation Act 1980, you have six years to claim for property damage and three years to claim for personal injury from the date of the accident.
Are there exceptions to the time limit?
For personal injury, the three-year period may start from the date you became aware of the injury rather than the accident date. Claims involving children don’t start the countdown until they turn 18.
Although these limits give you years to act, claiming promptly produces better outcomes. Evidence deteriorates, witnesses forget details, and insurers process recent claims more efficiently.
The full limitation rules are set out in the Limitation Act 1980. Claiming as soon as possible is always better because evidence is fresher and witnesses remember more clearly.
If you need a vehicle while your claim is being processed, temporary car insurance can get you back on the road quickly.
Frequently Asked Questions (FAQs)
Yes, you must inform your own insurer about the accident even if you’re not claiming through them. This is a policy requirement, and failing to report could invalidate your cover.
Yes, you can claim for all reasonable accident-related losses including medical costs, hire car, lost earnings, and travel expenses. All claims must be evidenced and proportionate.
They may offer a reduced settlement reflecting your percentage of fault. You can negotiate, provide additional evidence, or seek independent assessment if you disagree.
Yes, a police report strengthens your claim but isn’t mandatory for a civil insurance claim. Serious accidents involving injury should always be reported to police.
Not for straightforward claims you can handle directly. For complex cases involving personal injury or disputed liability, a solicitor is recommended and legal costs may be recoverable from the at-fault party.
