Insurer underpaying your repair claim?
When small claims is right for an RTA, when to use the Official Injury Claim portal, and when MIB applies. Property damage under £10k, uninsured drivers.
Personal injury under £5,000
Use the Official Injury Claim portal (officialinjuryclaim.org.uk) — set up under the Civil Liability Act 2018. It is free, designed for self-represented claimants, and handles whiplash and minor injuries from RTAs since May 2021.
Personal injury over £5,000
Outside the small claims limit for whiplash. Use a no-win-no-fee personal injury solicitor. Most work on conditional fee agreements with a success fee capped under the Conditional Fee Agreements Order 2013.
Property damage only (under £10,000)
If you suffered no injury — only damage to your car or its contents — small claims is the right forum. Common against uninsured drivers or insurers refusing to pay out fairly.
Uninsured driver claims
The Motor Insurers' Bureau (MIB) compensates victims of uninsured and untraced drivers under the Uninsured Drivers Agreement 2015. Apply directly to MIB before considering court action against the driver personally.
What counts as an uninsured loss
If the accident was not your fault, your own policy may cover the repair but leave you out of pocket on everything around it. Those gaps are what a small claim against the other driver is for:
- — the part you paid before your insurer paid anything.
- Hire or replacement transport
- — what it cost to keep moving while your car was off the road, if your policy did not provide a courtesy car.
- Belongings damaged in the car
- — a child seat that must be replaced after any impact, a laptop, tools, a phone.
- — shifts you could not work because you had no vehicle, with payslips to show the shortfall.
- — on a newer car, the drop in resale value caused by a recorded repair. You will need evidence from a dealer or valuer.
- Recovery, storage and reasonable travel
- — the incidental costs that follow a collision.
Personal injury is different. Whiplash and other lower-value injuries from road accidents go through the Official Injury Claim service rather than a standard small claim, and injury claims carry a three-year limit rather than six. Keep the injury element separate from the vehicle and property element.
Who you actually claim against
You can name the other driver, but in practice you deal with their insurer, and you can bring the claim directly against that insurer rather than the individual. That matters when the driver stops replying: the insurer still has to engage.
If the other driver was uninsured, or drove off and was never traced, the Motor Insurers’ Bureau exists for exactly that. It operates two separate schemes, one for uninsured drivers and one for untraced drivers, each with its own time limits and its own application. Report the accident to the police as soon as you can — an untraced-driver application is much harder without a crime reference.
Be careful with credit hire. If a hire company puts you in a car at no upfront cost and then pursues the other insurer, you may still be personally liable for the bill if the claim fails or the rate is found unreasonable. Read what you sign, and keep your own record of what a like-for-like hire would have cost locally.
The evidence that decides these claims
Liability in a road traffic claim is usually decided on documents and photographs, not on who sounds more convincing. Gather at the scene if you safely can, and afterwards while memory is fresh:
- Photographs of both vehicles in position before anything is moved, then the damage close up, then the wider road, signs and markings.
- Dashcam footage, saved and backed up immediately — most units overwrite on a loop within days.
- The other driver’s name, address, registration and insurer, and the name of the registered keeper if different.
- Independent witness details. A passenger in your own car carries less weight than someone unconnected to either driver.
- The police reference, if they attended or you reported it.
- Repair estimates, the invoice, the hire agreement and receipts for everything you are claiming.
Expect the other insurer to argue about the rate you paid rather than whether you were entitled to hire at all. Two independent quotes for equivalent hire, obtained at the time, answer that argument before it starts.
Which route is right for your case
Different RTA claims go to different forums. Pick the wrong one and your claim can be struck out for being in the wrong court.
Step-by-step: bringing an RTA claim
Honest warning: when to refer out
Some RTA cases are too complex or too valuable for self-representation. Get specialist help if:
- You suffered any personal injury — even soft-tissue or whiplash. Use the Official Injury Claim portal or a no-win-no-fee solicitor.
- Liability is genuinely contested with conflicting witness accounts.
- The other driver was uninsured or fled the scene — work with the MIB.
- Your loss exceeds £10,000 (above the small-claims limit) — fast-track and multi-track allow recoverable solicitor costs.
