The Motor Insurance Database and your fleet

The Motor Insurance Database (MID) is the central UK record of insured vehicles, run by the Motor Insurers’ Bureau (MIB) and used by police and DVLA. On a fleet policy, every vehicle should be added as soon as it joins the fleet and removed when it leaves.

Where you update records yourself through MIB’s system, on-cover and off-cover dates can only be backdated by up to 14 days, so changes should never be left to pile up.

For a business running a handful of vans, that sounds simple. In practice, fleets change constantly, and the MID is where small admin slips turn into roadside stops.

This guide covers how the database works for fleets, who does what, and a process you can adopt.

What Does The Motor Insurance Database Do?

The MID is the record that tells the authorities which vehicles are insured. Police use it at the roadside and DVLA uses it to enforce the rule that registered vehicles must stay insured.

Who relies on the record

Police use the database at the roadside, and MIB supplies data and resources to police and enforcement officials for that work. Police operations have compared automatic number plate recognition (ANPR) camera data with MID records to find uninsured vehicles.

Checking a vehicle on askMID

Anyone can check whether a vehicle shows as insured using askMID. You enter a registration and the service tells you whether a matching record exists.

askMID also offers a paid enquiry for people involved in an accident who need to check whether the other vehicle is insured.

Cover and records are different things

The key point for a fleet manager is this: the policy decides whether a vehicle is insured, but the MID decides whether it looks insured to everyone checking. Both need to be right.

How Do Fleet Policies Appear On The MID?

Each vehicle on a fleet policy needs its own entry, with the dates it went on and off cover. MIB’s guidance for fleets says those records should cover temporary vehicles such as courtesy cars and short-term hire vehicles as well as permanent ones.

One entry per vehicle

A single-vehicle policy creates one MID record when the policy starts. A fleet policy is different, because vehicles come and go throughout the year.

Temporary and hire vehicles

MIB’s guidance for fleets says the records should include permanent vehicles and temporary ones, such as courtesy vehicles and short-term hire vehicles. That catches out businesses that assume a hired van for a fortnight is “covered by the policy” and needs nothing more.

Policies that cover any vehicle owned or hired

Some fleet policies are written to cover any vehicle owned by or hired to the policyholder, rather than listing registrations. Section 144A of the Road Traffic Act 1988 recognises this style of cover for Continuous Insurance Enforcement purposes.

It does not remove the practical need for each vehicle to be recorded, so treat the MID as the vehicle list that matters. If you want the basics of how a fleet policy is built, our guide on what fleet insurance is explains schedules, certificates and mid-term adjustments.

Who Updates The MID Record For A Fleet?

Either the insurer or broker enters changes when you report them, or, where the insurer allows it, your business enters them itself through MIB’s system. Your policy documents or broker will tell you which applies.

The two set-ups

Set-up	Who enters changes	What you need to do
Insurer or broker updates	The insurer, or the broker on its behalf	Report every change promptly, in writing, with registration and dates
Policyholder updates	Your business, through MIB’s policyholder system	Enter additions and removals yourself and download the vehicle schedule to check

What the policyholder system allows

Under the second set-up, MIB’s policyholder guide confirms you can add vehicles, amend off-cover dates and download vehicle schedules. Not every insurer offers this, so ask before assuming you have access.

Where the update chain starts

Even where the broker does the entering, the business is the only party that knows a van has been delivered or sold. The update chain starts with you.

What Are The Deadlines For Updating The MID?

The one firm figure in MIB’s own guide is the backdating limit: a policyholder entering an on-cover or off-cover date in MIB’s system can backdate it by no more than 14 days. Insurers can backdate further.

What is actually confirmed

This is the area where most confusion arises, and where you will find the widest range of claims online. What is confirmed in MIB’s own guide is narrow.

The safe approach

• Add vehicles to the MID as soon as they join the fleet, and remove them when they leave.
• Don’t let changes build up for a monthly admin session. The 14-day limit on self-entered backdating means a late entry may not reach back to the real on-cover date.
• Read your policy terms. Your insurer may set a shorter deadline for telling it about changes.

Deadlines we don’t repeat

You may see pages stating a fixed legal deadline for fleet MID updates. We have not found that in an official source, so we don’t repeat it here.

If a specific deadline matters to your operation, ask the broker to confirm it in writing against your policy.

Delivery day

Watch out: A new van driven off the dealer’s forecourt on the day of delivery may not show on askMID yet, even if the policy covers it. Where possible, arrange the update before collection day.

What Happens When A Fleet Vehicle Is Missing From The MID?

A vehicle that does not show as insured can be stopped by police, and the registered keeper can face Continuous Insurance Enforcement action. A gap in the record causes problems in those two separate ways.

At the roadside

A vehicle that doesn’t show as insured can be stopped by police. Where police are not satisfied the vehicle is insured, the consequences for driving without insurance can be serious: a £300 fixed penalty and 6 penalty points, or an unlimited fine and possible disqualification if the case goes to court.

Police can also seize the vehicle. MIB notes that a new policy or change can be too recent to show in its data, so if the vehicle is in fact insured, the driver may be able to show this.

Even then, the stop, the paperwork and any vehicle recovery cost the business time.

Through Continuous Insurance Enforcement

In Great Britain, the registered keeper must keep a vehicle insured unless it has been declared off the road with a SORN. Enforcement uses DVLA and MID records, so a vehicle missing from the MID can trigger action.

The keeper penalties for an uninsured vehicle are a £100 fine and possible clamping, impounding or destruction of the vehicle, with a maximum fine of £1,000 if the case goes to court. The keeper still has to insure the vehicle as well.

Vehicles standing idle

For fleets, that risk is highest with vehicles that sit in the yard between jobs. A van waiting for repairs, or one kept as a spare, still needs insuring and recording unless it has a valid SORN.

What Should You Do When A Vehicle Leaves The Fleet?

Report the off-cover date as soon as the vehicle is sold, returned or written off, then confirm the schedule no longer lists it. If the vehicle is being kept off the road instead, decide whether to declare a SORN and whether you still want cover while it is parked.

Removals matter as much as additions

A sold vehicle left on your record means you may be paying for it, and it muddies your schedule at renewal.

Taking a vehicle off the road

If you take a vehicle off the road, a SORN means it does not need to be taxed or insured while it stays off the road. It can only be driven on a road to or from a pre-booked MOT or other test, and it needs insuring for that journey.

Using a SORN vehicle on the road for any other reason can lead to a fine of up to £2,500.

Laid-up cover

Tell the broker before taking a laid-up vehicle off cover. Fire and theft cover while it is parked is a separate decision from road cover.

How Should You Add And Remove Vehicles In Practice?

Confirm the vehicle fits the policy, report or enter the on-cover date, get written confirmation and check the registration on askMID before the vehicle is driven. Reverse those steps when it leaves, and reconcile the whole schedule once a month.

Use the lists below as a starting point and adapt them to how your policy is administered.

When a vehicle joins the fleet

• Confirm the vehicle fits the policy: type, weight, class of use and any modifications
• Send the registration, make, model, value and on-cover date to the broker, or enter it yourself if you have access
• Get written confirmation that the vehicle is added
• Check the registration on askMID before the vehicle is driven where you can
• Update your internal fleet list and the driver booking log

When a vehicle leaves the fleet

• Record the date it was sold, returned or written off
• Report the off-cover date to the broker or enter it yourself
• If the vehicle is being kept off the road, decide on a SORN and whether any laid-up cover is wanted
• Confirm the schedule no longer lists it

Every month

• Download or request the current vehicle schedule
• Compare it line by line with your own list of vehicles in use
• Spot-check a sample of registrations on askMID, including any hire or courtesy vehicles
• Fix any mismatch the same day

Our fleet schedule template gives you a simple list to reconcile against.

What Fixes Most Fleet MID Problems?

Most MID problems are process problems rather than insurance problems. Naming one person, building the update into the vehicle handover and reconciling monthly fixes most of them.

Why records drift

Nobody deliberately leaves a van off the database. It happens because the person who collects the vehicle is not the person who talks to the broker, or because updates are saved up to send in one go.

Three decisions

1. Name one person who owns MID updates, with a named deputy for holidays.
2. Make reporting part of the vehicle handover. No keys are issued until the addition is confirmed.
3. Reconcile monthly. A short check against your schedule and askMID catches drift before police or DVLA do.

What to ask a broker

When you talk to a broker about a new policy, ask how MID updates work under it, whether you can update records yourself, and what deadline the policy sets for reporting changes. For larger or fast-changing fleets, such as van fleets with frequent replacements or hire vehicles, that admin can matter as much as the price.

Our fleet insurance renewal checklist includes MID checks to run when a new policy starts, and the main fleet insurance page explains what insurers look at when they quote.
