Motor Insurers Bureau: What It Is and How to Claim

The Motor Insurers’ Bureau is the UK body that pays compensation to people injured or whose property is damaged by uninsured or untraced (hit-and-run) drivers. Set up in 1946 and funded by every insurer that sells compulsory motor cover, the Motor Insurers’ Bureau (MIB) acts as a safety net when there is no valid insurance to claim against.

For most drivers, the MIB works quietly in the background. You do not buy anything from it, and you never deal with it unless you are hit by someone with no insurance or you fail to insure a vehicle you own. Free Price Compare compares car insurance from a panel of 130+ insurers, and every one of those insurers is a member of the MIB by law, so a small part of what you pay helps fund it.

Below is a plain explanation of what the MIB does, when you can claim, how a claim compares with going through your own insurer, and why some drivers receive letters from the MIB about a car they own.

What is the Motor Insurers’ Bureau?

The Motor Insurers’ Bureau is a not-for-profit organisation, founded in the UK in 1946, that compensates victims of collisions caused by uninsured or untraced drivers. It exists because compulsory motor insurance under the Road Traffic Act 1988 protects other road users, and the MIB fills the gap when the at-fault driver has no valid cover or cannot be found.

The MIB is funded entirely by insurers. Under a long-standing arrangement, every insurer that underwrites compulsory motor insurance in the UK must be a member and contribute to MIB funding. Those contributions are recovered through the premiums drivers pay, which is why the MIB is often described as a levy on honest motorists. The Association of British Insurers (ABI) has estimated that uninsured driving adds around £30 to the cost of every motor insurance policy.

The MIB also operates two key agreements with the government: the Uninsured Drivers’ Agreement and the Untraced Drivers’ Agreement. These set out when and how it pays out, and they are the legal basis for the two main claim routes.

Free Price Compare sources market context from bodies like the Association of British Insurers (ABI) and official sources such as GOV.UK, both of which recognise the MIB as the claims body for uninsured and hit-and-run incidents.

Can I claim compensation if hit by an uninsured or hit-and-run driver?

Yes. You can claim compensation through the Motor Insurers’ Bureau if you are injured or your property is damaged by an uninsured driver, or by an untraced (hit-and-run) driver you cannot identify. This applies to incidents on a road or other public place in Great Britain, in line with the Road Traffic Act 1988 and the MIB’s agreements with the government. The ABI confirms that the MIB was established to compensate victims of negligent uninsured and untraced motorists, providing a route to compensation where there is no insurer against which a conventional claim can be made.

There are two distinct routes. An uninsured driver claim applies when the at-fault driver is known but has no valid insurance. An untraced driver claim applies when you cannot identify the driver at all, for example after a hit-and-run. The evidence you need differs: for an untraced claim you should report the incident to the police and get a crime reference number, because the MIB will expect proof that reasonable steps were taken to find the driver.

The MIB can pay for personal injury and, in many cases, property or vehicle damage, subject to the terms of the relevant agreement. You do not need to have been the driver to claim, passengers and pedestrians hit by an uninsured or untraced vehicle can also apply.

How do I make an MIB claim?

To make an MIB claim, contact the Motor Insurers’ Bureau directly on 01908 830001 or start a claim through its official website, then provide details of the incident, any injuries, and evidence such as photos, witness details and a police report. GOV.UK lists the MIB’s postal address as Linford Wood House, 6-12 Capital Drive, Linford Wood, Milton Keynes, MK14 6XT (GOV.UK, page last updated August 2026).

Report the incident to the police as soon as possible, especially for a hit-and-run, and keep the crime reference number. Gather the other vehicle’s registration where you can, photograph the scene and damage, and note any witnesses. Keep records of medical treatment and out-of-pocket costs, as these support an injury claim.

Free Price Compare does not handle MIB claims. If you are unsure whether to claim through the MIB or your own insurer, it is worth understanding how the two compare first.

Should I claim on my own insurance or through the MIB?

If you hold comprehensive car insurance, claiming on your own policy is usually faster than going through the Motor Insurers’ Bureau, because your insurer can start assessing the damage straight away rather than waiting for MIB investigation and eligibility checks. MIB claims can take longer, particularly untraced driver cases where the driver must be shown to be unidentifiable.

The trade-off is that claiming on your own comprehensive policy may affect your no-claims bonus and could mean paying your excess up front, even when the accident was not your fault. In some cases your insurer will pursue the uninsured driver or the MIB on your behalf and refund your excess once recovered. Around 88-89% of car insurance quotes through Free Price Compare are for comprehensive cover (Free Price Compare data, January to June 2026), so this is the most common situation our buyers face.

If you only hold third party, fire and theft or third party only cover, your own policy will not pay for damage to your car after an accident that was not your fault. In that case an MIB claim, or a claim against the other driver directly if they are known but uninsured, may be your main route to recover losses.

• Comprehensive cover: claim on your own policy for speed, then let your insurer recover from the MIB where possible.
• Third party only or third party fire and theft: an MIB claim may be needed for your own losses.
• Personal injury: you can pursue an MIB injury claim regardless of your cover level.

Choosing the right level of cover before an incident matters. Our guide to how a car insurance quote is built explains what drives the price of each cover level.

What is the Motor Insurance Database and why do paper documents matter less?

The Motor Insurance Database (MID) is the central record of every insured vehicle in the UK, run by the Motor Insurers’ Bureau. Police and the DVLA use it to check instantly whether a vehicle is insured, which is why paper insurance certificates are no longer routinely needed at the roadside.

When you buy a policy, your insurer adds your vehicle to the MID, usually within a few days. Police automatic number plate recognition (ANPR) cameras check registrations against the MID continuously, so an uninsured vehicle can be flagged without an officer ever seeing a paper certificate. This is also how Continuous Insurance Enforcement works: if a registered vehicle appears on DVLA records with no insurance and is not declared off the road with a SORN, the keeper can be penalised.

If you have just insured a new car and it is not yet showing on the MID, allow a short time for your insurer to update it, and keep your policy documents in case you need to prove cover. You can check your own vehicle’s status through the free askMID service.

Why did I get a letter from the Motor Insurers’ Bureau?

A letter from the Motor Insurers’ Bureau usually means either that a vehicle registered to you appears to have no insurance, or that the MIB is contacting you as a party to an incident involving an uninsured or untraced driver. The MIB manages the Motor Insurance Database, so it can identify vehicles that show as uninsured on DVLA records.

If the letter is about an apparently uninsured vehicle, it is part of Continuous Insurance Enforcement. You must either insure the vehicle or declare it off the road with a Statutory Off Road Notification (SORN) through the DVLA. Driving without insurance is an offence under the Road Traffic Act 1988 and can lead to a fixed penalty, points, a court fine and vehicle seizure, so do not ignore the letter.

If the MIB is contacting you because you were allegedly at fault in an incident where it paid a victim, it may seek to recover those costs from you. The MIB is legally entitled to pursue the uninsured party for money it has paid out, which is why some drivers receive demands for substantial sums. If you receive a recovery letter you dispute, respond promptly, keep all your evidence, and consider taking independent legal advice rather than ignoring it.

Does the MIB affect what I pay for car insurance?

The Motor Insurers’ Bureau affects car insurance prices indirectly, because insurers fund it through their membership contributions and recover that cost within the premiums drivers pay. There is no separate MIB charge on your policy, and the exact per-driver contribution is not published as a fixed figure by an official UK source.

The larger drivers of premiums are claim costs and repair inflation, not the MIB levy. According to the ABI Motor Insurance Premium Tracker, the average private comprehensive motor premium was around £560 in Q1 2026, up £1 (0.2%) on the previous quarter and £20 lower than a year earlier (ABI, published 30 April 2026). Over the same period the ABI reported the average accidental damage claim cost at around £3,699, up 8% on the previous quarter, showing how repair costs keep pressure on prices.

Reducing uninsured driving is one way the MIB helps hold costs down over time, because fewer uninsured claims means less to fund. For individual drivers, the most direct way to manage cost is to compare cover before renewing. Our tips to reduce your car insurance premium set out practical steps.

How fronting and named drivers relate to insurance validity

Fronting is when the main driver of a car is deliberately named as a named driver on someone else’s policy, usually a parent’s, to get a cheaper price, and it is a form of insurance fraud. A named driver is a genuine additional driver, while the policyholder should be the person who actually drives the car most.

Fronting matters because it can invalidate a policy. If an insurer finds the named arrangement did not reflect real use, it can refuse a claim, cancel the policy and record the fraud, which makes future cover harder and more expensive. Insurers detect fronting by cross-checking who the registered keeper is, the age and experience mismatch between policyholder and named driver, address links and claims history.

An invalidated policy can leave you in the same position as an uninsured driver, exposed to prosecution and, potentially, an MIB recovery action if a victim has to be compensated. Around a third of car insurance quotes through Free Price Compare, roughly 32-39%, come from drivers with no no-claims bonus (Free Price Compare data, January to June 2026), a group where the temptation to cut costs through fronting is highest, so it is worth stressing: insure the real main driver honestly.
