Is checking an MOT history really free?

Yes. The official GOV.UK service is completely free to use and you do not need to create an account. Be wary of other sites that charge a fee for the same information.

Do I need the log book to check a car’s history?

No, the registration number is enough to see the results. You only need the 11-digit number from the V5C log book if you also want to see where each test was carried out.

How far back does the MOT history go?

For cars, vans and motorcycles the online records go back to 2005. Older results before that date are not held on the digital service.

Can I see the mileage at each test?

Yes. The service lists the mileage recorded at every test, which is one of the most useful ways to spot an odometer that does not add up.

How to check your car’s MOT history

Every car in England, Scotland and Wales that has taken an MOT since 2005 has a public record you can look up in under a minute. The service is run by the government, it is free, and you only need the number plate to get started. Whether you are keeping an eye on your own car or sizing up a used one before you buy, the MOT history is one of the most honest snapshots of a vehicle you can get.

What the MOT history service is

The MOT history check is an official GOV.UK service that stores the results of every MOT a vehicle has taken. It records whether the car passed or failed, the mileage that was on the clock at the time, and any faults or advisories the tester noted. Because the data comes straight from the testing station and cannot be edited by a seller, it gives you a version of the car’s past that does not rely on anyone’s word.

It is worth being clear about what the service is not. It does not value the car, tell you about accident damage, or confirm whether outstanding finance is owed. For those you would need separate checks. What it does brilliantly is show you the maintenance story the MOT leaves behind.

What you need to check

To see the results you need nothing more than the registration number. Type it in and the history appears. If you also want to see where each test was carried out, you will need the 11-digit reference number from the vehicle’s V5C log book. That extra detail is optional, so a quick history check on a car you are thinking of buying can be done from your phone before you have even seen the paperwork.

Two points on coverage are worth knowing. First, the online records for cars, vans and motorcycles reach back to 2005, so a very old vehicle may have earlier tests that are simply not held digitally. Northern Ireland records begin later, so the depth of history varies depending on where the car has lived. Second, only the official GOV.UK service is free. Various third-party websites repackage the same public data and charge for it, or bundle it with checks you may not need, so if you find yourself asked to pay for an MOT history you are almost certainly on the wrong page. Go straight to the government service and you will get the full record at no cost.

What the MOT history shows you

Once you are in, the record is laid out test by test, newest first. Here is what each entry gives you.

What you see	Why it is useful
Pass or fail result	A clear record of how the car has fared over the years
Mileage at each test	Lets you check the mileage climbs steadily and has not been wound back
Failure reasons	Shows exactly which parts failed and whether the same fault keeps returning
Advisories	Flags items the tester wanted monitored, which often become failures later
Next MOT due date	Tells you when the current certificate runs out
Safety recalls	Highlights whether the vehicle may be subject to a manufacturer recall

The failure reasons and advisories are where the real value sits. If you want to understand the difference between something the tester merely noted and something that caused a fail, our guide on what an MOT advisory means breaks it down, and why cars fail their MOT covers the faults that come up most often.

How to check when your MOT is due

The same records tell you when the next MOT is due, and there is also a dedicated GOV.UK page for checking MOT status if that is all you need. Driving without a valid MOT is against the law in almost every case, so knowing the exact expiry date matters. If yours is close, it is worth reading whether you can drive without an MOT so you understand the few narrow exceptions. You can book a test up to a month before it expires and keep the same renewal date, which is the simplest way to avoid a lapse.

Why it matters when buying a used car

If you take one thing from this guide, let it be this: check the MOT history before you buy any used car. It is free, it is instant, and it can save you from an expensive mistake.

Start with the mileage. Because the figure is recorded at every test, you can watch it climb year on year. A reading that jumps oddly, or drops between tests, is a warning sign that the odometer may have been tampered with. A car advertised as low mileage should have a history that quietly backs that up.

Next, look for patterns in the faults. One failed test years ago is nothing to worry about, but the same advisory appearing again and again, say a slightly worn ball joint or a corroded brake pipe, tells you a niggle has been left to fester. A long run of clean passes with sensible advisories, on the other hand, points to a car that has been looked after.

Finally, use the record as a conversation starter. If the seller’s story does not match the history, that is useful to know before any money changes hands. A trustworthy seller will happily talk you through the advisories and what has been done about them.

Once you own the car, the MOT history stays just as useful. It becomes a running logbook of its condition, and a strong history is something you can point to when you come to sell. Keeping on top of advisories rather than letting them pile up is the surest way to keep future tests short and cheap.
