How Long Does a Third Party Insurance Claim Take?
Most third-party car insurance claims settle within 4 to 12 weeks when liability is clear. Simple cases with admitted fault and minor damage can be resolved in two to four weeks, while disputed or injury-related claims can take three to six months.
A third-party claim means you are claiming against the at-fault driver’s insurer rather than your own. This protects your no claims bonus, but it also means you depend on the other insurer’s processes and speed.
Our guide to third-party only car insurance explains how this cover level works and what it includes.
Weeks if liability is clear, months if it is disputed or there is an injury element.
Compare car insurance quotes and consider whether comprehensive cover would settle you faster next time.

What does the third-party claims timeline look like?
Every third-party claim passes through five stages, each with its own timeframe. The table below breaks down a typical claim from start to settlement.
Stage-by-stage timeline
| Stage | Typical timeframe | What happens |
| Report the accident | Day 1 | You notify the at-fault driver’s insurer with evidence and your account of the incident |
| Liability investigation | 1-4 weeks | The insurer reviews evidence, contacts witnesses, and decides whether their policyholder was at fault |
| Damage assessment | 1-2 weeks | An engineer or approved repairer inspects your vehicle and provides a repair estimate or write-off valuation |
| Settlement offer | 1-2 weeks after assessment | The insurer makes a financial offer covering repairs, hire car costs, and any other losses |
| Payment | 5-10 working days | Once you accept the offer, payment is transferred to your account or directly to the repairer |
What is the fastest realistic outcome?
A simple claim with dashcam footage, admitted liability, and minor damage can settle in as little as two to three weeks. The liability stage shrinks to a few days when the evidence is clear.
What causes the biggest delays in third-party claims?
Disputed liability is the single biggest delay factor. If the other driver tells their insurer a different version of events, both sides must gather evidence independently, which can add four to six weeks.
How do documentation gaps slow things down?
Insurers cannot progress a claim without repair quotes, photographs, and supporting evidence. Submitting incomplete information forces them to chase you, adding unnecessary time to every stage.
The most avoidable delay is failing to send everything at once. Drip-feeding documents resets the queue each time the insurer receives a new item.
Does vehicle type affect the timeline?
Modified, rare, or specialist vehicles take longer to assess because parts sourcing and repair estimates require specialist input. A standard hatchback repair might be assessed in two days, while a modified vehicle could take two weeks.
What about personal injury claims?
Injury claims take much longer because medical assessments must be completed before the full value is known. Whiplash claims alone routinely take three to six months, and more serious injuries can extend beyond a year.
How can you speed up a third-party claim?
The fastest claims are those where complete, accurate evidence is provided from day one. GOV.UK’s accident guidance sets out what you should record at the scene.
What evidence should you gather immediately?
Photograph the damage from multiple angles, save dashcam footage before it overwrites, collect the other driver’s insurance details and registration number, and note the time, date, and weather conditions. Witness contact details are also valuable.
Dashcam footage is the single most effective tool for resolving liability disputes. Clear video evidence can cut weeks off the investigation stage.
How should you handle communication with the insurer?
Respond to every request within 48 hours and keep a log of every phone call and email, noting the date, who you spoke to, and what was discussed. Follow up every two weeks if you have not received an update.
What can you do if the claim is taking too long?
If your claim stalls, escalate through the insurer’s formal complaints process. If that fails, the Financial Ombudsman Service can investigate at no cost to you.
When should you escalate?
If you have heard nothing for three weeks despite chasing, ask to speak to a manager or complaints handler. The insurer has eight weeks to provide a final response under FCA rules.
If eight weeks pass without resolution, or if you receive a final response you disagree with, you can refer the complaint to the Financial Ombudsman.
Can your own insurer help?
Yes, if you have fully comprehensive cover, your own insurer can step in to repair your vehicle and then recover the costs from the at-fault driver’s insurer through subrogation. This gets your car back faster while the insurers sort out the money between themselves.
Will a third-party claim affect your no claims bonus?
A successful third-party claim should not affect your no claims bonus, because you are claiming against the other driver’s policy rather than your own.
Do you still need to report the accident to your insurer?
Yes, most policies require you to report every accident regardless of fault. A notification-only report does not count as a claim and should not affect your no claims discount.
What happens if liability is shared?
If fault is split, your insurer may need to cover part of the cost, which could affect your no claims bonus and increase your premium at renewal. Our breakdown of car insurance costs explains how claims history affects what you pay.
What happens if the other driver is uninsured?
If the at-fault driver has no insurance, you can claim through the Motor Insurers’ Bureau. MIB claims follow a different process and typically take longer than standard third-party claims.
How does the MIB process work?
You submit your claim directly to the MIB with the same evidence you would provide to an insurer. The MIB investigates, and if your claim is valid, they compensate you from a fund paid into by all UK motor insurers.
MIB claims can take six months or longer, particularly if the uninsured driver cannot be traced. Your own insurer may require you to claim through your comprehensive cover first and then seek recovery.
How common are uninsured drivers?
The MIB estimates that around one million vehicles in the UK are driven without insurance. If you are hit by an uninsured driver, the MIB exists specifically to ensure you are not left out of pocket.

Frequently Asked Questions (FAQs)
Yes, if the accident was not your fault, the other driver’s insurer should cover reasonable hire car costs while your vehicle is being repaired. Check what daily rate limit applies before arranging a hire vehicle.
No, you have the right to choose your own repairer. However, the other insurer will need to approve the repair estimate, and using their approved repairer can sometimes speed up the process because the estimate is pre-agreed.
Yes, claims involving disputed liability, personal injury, or multiple vehicles can take well beyond three months. Some serious injury cases take six months to a year or longer.
No, reporting and claiming are separate actions. You can notify your insurer about an accident without submitting a claim, which protects your position without necessarily affecting your no claims bonus.
This happens more often than you might expect. Dashcam footage and independent witness statements are your best protection, because a verbal admission at the scene is difficult to prove without supporting evidence.
Yes, if the accident caused you to miss work, you can claim for lost earnings as part of your third-party claim. You need to provide payslips, employer letters, or tax returns showing the income you lost.
