Over a million vehicles on UK roads are uninsured, according to the latest estimates. That means if you’re hit by one, there’s no insurer on the other side to pay for your repairs or a replacement car. The Motor Insurers’ Bureau (MIB) steps in as a last-resort fund, but property damage claims come with strict rules, a mandatory £300 excess, and time limits that catch people out every day.

The MIB operates under two separate agreements. Which one applies depends on whether the at-fault driver can be identified. If they’re known but uninsured, the Uninsured Drivers Agreement 2017 (UDA) covers property damage after you pay the first £300. If the driver fled and can’t be traced, the Untraced Drivers Agreement 2017 (UTDA) generally does not cover vehicle damage unless you have strong corroborating evidence – and even then, it’s limited. Understanding which route you’re on changes everything about what you do next. Here’s what you actually need to know.
What I tend to notice is that most people assume the MIB works like a normal insurer – it doesn’t. The process is slower, the evidence requirements are stricter, and the rules change depending on whether the other driver was caught or not. Knowing the difference between the two agreements is half the battle.
Property damage under the two MIB agreements: what you get and what you lose
The table below shows how the two agreements treat vehicle and property damage. The most important number to remember is the £300 excess – it applies to every successful UDA property damage claim, and it’s the first thing the MIB deducts from any payout.

| Agreement | Property damage covered? | Excess | Time limit to claim | Police report required? |
|---|---|---|---|---|
| Uninsured Drivers Agreement (UDA) | Yes – unlimited amount | £300 deducted from payout | 9 months from accident (some sources say 3 years – check with MIB) | Yes – obtain a crime reference number |
| Untraced Drivers Agreement (UTDA) | Only in limited cases with strong corroborating evidence | £300 may apply if covered | 3 years for personal injury; property damage must be reported within 14 days | Yes – must report within 14 days |
Around one in ten drivers on UK roads is uninsured, according to the MIB. That means the odds of being involved in a collision with one are higher than most people realise. The cost of that risk is already baked into your premium – an estimated £30 to £40 per policy goes towards covering uninsured driver claims.
If you’re hit by an uninsured driver and you have only third-party insurance, you cannot claim for your own vehicle damage through your policy. The MIB is your only route – and you’ll lose the first £300. That’s why the difference between third-party and comprehensive cover matters more than many people think.
Common mistakes that cost you money or your claim
Not reporting to the police within 14 days (hit-and-run cases)
Under the Untraced Drivers Agreement, you must report the accident to the police and get a crime reference number within 14 days. Miss that window and the MIB can refuse your claim entirely. I’ve seen people lose thousands because they assumed the police would be contacted automatically – they won’t. You have to do it yourself. Call 101 or visit a station, and keep the reference number safe.
Assuming your comprehensive insurance covers everything
Many comprehensive policies include an “Uninsured Driver Promise” that covers your repairs, waives the excess, and protects your no-claims bonus. But not all do. Check your policy wording carefully. If you have third-party fire and theft, you’re not covered for your own vehicle damage at all. The MIB will still pay, but you’ll face the £300 excess and a longer wait. Some insurers also require you to notify them within a set period – often 24 to 48 hours – or they may refuse to help.
Failing to gather evidence at the scene
The MIB investigates claims thoroughly. Without photos, witness details, or dashcam footage, they may reject a property damage claim under the UTDA because there’s no corroborating evidence. A dash cam can capture the other vehicle’s registration, the moment of impact, and the surrounding scene – all of which strengthen your case. If you don’t have one, take photos with your phone immediately, including the other car’s number plate, damage, and road conditions.
Missing the property damage time limit
While personal injury claims have a three-year limit under the Limitation Act 1980, property damage claims against the MIB may have a much shorter window. Some sources say 9 months, others say 3 years – the discrepancy exists because the MIB’s agreements differ from standard limitation periods. The safest approach is to start your claim as soon as possible. Don’t wait to see if your injuries heal; file the property damage part early.
Here’s a quick checklist of what to do in the first hour after an accident involving a suspected uninsured driver:
- Check for injuries and move to safety if possible
- Call the police (999 if injuries, 101 otherwise) and request a crime reference number
- Photograph the scene, both vehicles, damage, number plates, and road conditions
- Get names and contact details of any witnesses
- Note the other vehicle’s make, model, colour, and registration
- Do not confront the other driver – uninsured drivers may be aggressive
- Contact your insurer as soon as possible, even if you don’t plan to claim through them
How to make an MIB claim for property damage – step by step
Step 1: Report to the police and get a crime reference
This is non-negotiable. Without a police report, the MIB will not process your claim. For hit-and-run cases, you have 14 days. For identified uninsured drivers, report it anyway – uninsured driving is a criminal offence, and the police report becomes key evidence.
Step 2: Gather and organise your evidence
The MIB requires clear proof of the accident, the other vehicle’s involvement, and the damage. Collect photos, witness statements, dashcam footage, repair estimates, and any receipts for out-of-pocket costs. If you have a dash cam with GPS, the footage can also show your speed and location, which helps establish liability.
Step 3: Notify your own insurer
Even if you’re not claiming through them, your insurer needs to know about the accident. They can advise on whether your policy includes an Uninsured Driver Promise, and they may handle the claim on your behalf if you have comprehensive cover. Some policies also require you to report the incident within a specific timeframe to protect your no-claims bonus.
Step 4: Submit your claim to the MIB online
Paper forms are no longer accepted. Go to mib.org.uk and register for an account. You’ll need to provide details of the accident, upload your evidence, and include the police crime reference number. The MIB will issue a claim reference number – keep it for all future correspondence.
Step 5: Consider legal assistance for complex cases
MIB claims can take months, especially if liability is disputed. Many solicitors handle these cases on a No Win No Fee basis. If your injuries are significant or the property damage is high, a specialist can ensure deadlines are met and evidence is presented correctly. For straightforward property damage under the UDA, you may be able to handle it yourself, but the £300 excess still applies.
Emerging change: government proposals to restrict property damage claims
In 2025, the UK government published proposals that would prevent uninsured drivers themselves from claiming property damage compensation through the MIB. If implemented, this change would only affect claimants who were uninsured at the time of the accident – not innocent victims. Personal injury claims would remain unaffected. Keep an eye on these reforms if you’re involved in a claim, as they could alter eligibility rules.
Should you claim through your own comprehensive insurance or go directly to the MIB? It depends on your policy. Here’s how the two options compare:
- Your insurer handles repairs and may waive the excess
- No-claims bonus is protected if you’re not at fault
- Faster process – your insurer deals with the MIB for recovery
- Requires you to have comprehensive cover and the promise included
- Your premium may still rise, though some policies guarantee no increase
- Available to anyone, regardless of their own insurance level
- £300 excess applies to property damage under UDA
- Slower process – MIB investigates thoroughly
- No impact on your no-claims bonus (you’re not claiming on your policy)
- You must submit all evidence yourself and meet strict deadlines

Act now – the clock starts the moment you’re hit
The single most important thing you can do after an accident with an uninsured or untraced driver is to act immediately. Report to the police, gather evidence, and notify your insurer – all within the first few days. The £300 excess may sting, but it’s far better than losing the entire claim because you missed a deadline or failed to document the scene. The MIB exists to protect innocent victims, but it’s not a safety net that catches everyone. You have to take the right steps, in the right order, and on time.
