Did you know that a car’s registration number unlocks a surprising amount of information about its history? Whether you are buying a used car, checking your own vehicle’s status, or simply want to know when your MOT is due, a free vehicle check by reg is one of the most useful tools available to UK drivers.
In this guide we explain exactly what a vehicle check reveals, how to do a car reg lookup for free, and what to look out for when checking a used car before buying.
What Is a Vehicle Check?
A vehicle check (also called a car reg check, reg check, or vehicle registration check) is an online lookup that uses a car’s number plate to pull official DVSA and DVLA records. Within seconds you can find out a wide range of details about any vehicle registered in the UK.
At ExpressMot, our free vehicle check tool lets you run an instant car reg lookup simply by entering a registration number. No account needed, no payment required.
What Does a Free Vehicle Check Show You?
When you run a vehicle check by registration number, you can find out:
MOT status and due date The most important piece of information for any driver. The check shows whether a car currently has a valid MOT, when it expires, and the complete MOT history going back years — including every pass, fail, and advisory notice.
Mileage history Every time a car goes through an MOT, the mileage is recorded. Your vehicle reg check will show the mileage at each test date. This is the fastest way to spot a clocked car — if the mileage drops between tests or jumps suspiciously, something is wrong.
Vehicle details The car reg lookup returns the make, model, engine size, fuel type, colour, and year of first registration for any UK vehicle. Useful for confirming that the car you are looking at matches what the seller has told you.
MOT test results in detail The mot on vehicle check shows not just pass or fail, but every item that was flagged — dangerous faults, major faults, and advisory notices. This is genuinely useful for understanding the condition of a used car before you commit to buying.
Tax status The vehicle check will show whether road tax (Vehicle Excise Duty) is currently paid, and when it expires. An untaxed car is a red flag and cannot legally be driven on public roads.

Vehicle Check for Used Car Buyers — What to Look For
If you are buying a second-hand car, a free vehicle check is the absolute minimum you should do before handing over any money. Here is what to look for in the results:
Check the MOT is valid Never buy a car without first confirming the mot of car check shows a current, valid certificate. A car being sold with no MOT may have hidden faults the seller does not want you to know about.
Look at the advisory history Advisories are warnings given during an MOT that were not serious enough to fail the car — but they indicate wear that will eventually need attention. If the same advisory appears test after test (for example, “brake pads wearing thin”), it suggests the owner has been ignoring maintenance.
Check for mileage consistency Use the vehicle check to verify the mileage recorded at each MOT. Compare it against the current odometer reading shown by the seller. Any inconsistency is a serious warning sign.
Check the MOT due date If the MOT expires in the next few weeks, factor the cost of a new test (and potential repairs) into your negotiation. Use our mot and vehicle check to see exactly how much valid MOT time is left.
Verify the car details match The car reg lookup will return the registered colour, make, and model. Make sure these match the physical car you are viewing. Mismatches can indicate the car has been involved in serious damage or is not what it appears.
Car Reg Lookup — Common Questions
Is a vehicle check really free? Yes. The basic MOT and vehicle check at ExpressMot is completely free. You get MOT status, due date, full test history, and vehicle details at no cost.
Can I check any car, not just my own? Yes. You can run a vehicle registration checking on any UK-registered vehicle using its number plate. This is particularly useful when buying a used car.
How up to date is the information? The DVSA updates MOT records in real time — as soon as a test result is recorded by a test centre, it appears in the database. Tax status is updated by the DVLA and is typically current within 24 hours.
What if my vehicle check shows the MOT has expired? If your mot reg check shows an expired MOT, do not drive the car. Book an MOT test immediately using our online booking tool. We have same-day and next-day slots available at MOT centres near you.
Can I check my MOT by registration number? Yes — this is exactly what the check my reg tool does. Enter your own car’s registration and you will see your current MOT status, due date, and history in seconds.

Checking Vehicle Details With a Registration Number — Beyond the MOT
A car reg lookup gives you MOT and tax data for free. For a more complete picture before buying a used car, you may want to consider a paid HPI-style check which adds:
- Finance check — whether outstanding finance is owed on the vehicle
- Written-off status — whether the car has been declared a total loss by an insurer
- Stolen status — whether the vehicle has been reported stolen
- Number plate change history — whether the reg has been altered
These paid checks use the same registration number as the free vehicle check, and are worth the cost for expensive purchases. However, for most everyday needs — confirming your own MOT status, checking a due date, or getting a quick overview of a vehicle’s test history — the free car reg check at ExpressMot gives you everything you need.
