Best Car Check App UK: What Apps Can and Cannot Do
Car check apps are good for free DVLA and MOT lookups and reminders. They cannot show finance, write-off or stolen markers free. Here is why.
Online MOT history goes back to about 2005. That is when the DVSA computerised MOT system was rolled out across test stations, and tests carried out before a station switched over were written on paper certificates that were never keyed into the database. A 1997 car can be entirely genuine and still show its first online test in 2005 or 2006.
The free GOV.UK MOT history service shows tests recorded electronically, which in practice means from around 2005 onwards. There is no online archive of earlier tests and the DVSA cannot produce one. If a car shows fewer tests than you expected, the usual explanations are its age, a recent import, a spell off the road on a SORN, or a change of registration. A full MOT check pulls every recorded test, the mileage at each one and the advisories into a single list, which is the part a buyer actually needs.
Every recorded test gives you the same short set of facts, and nothing beyond them.
It does not tell you who owned the car, what was repaired afterwards, whether it was serviced, or why it sat unused for two years. The MOT record is a safety snapshot taken once a year, not a biography.
Before computerisation, an MOT result existed as a paper certificate handed over at the test station, a VT20 for a pass and a VT30 for a refusal. Stations moved onto the central system in stages rather than all at once, so the cut off is soft. Some vehicles have online results from 2005, others show nothing until 2006 or later, and neither pattern is a warning sign on its own.
Older certificates were never added retrospectively. If you want evidence of a test from the 1990s, the only source is the paper certificate in the car's history file, and plenty of those have been lost across four or five owners. Treat a thick folder of old certificates as a bonus rather than something you can insist on.
Most missing MOT history has a dull explanation. Work through these before you assume something has been hidden.
| What you see | Usual reason | What to do |
|---|---|---|
| Nothing at all on a nearly new car | The first MOT is not due until the vehicle is three years old | Nothing. Check the date of first registration on the V5C instead. |
| History starts years into the car's life | The vehicle was imported and the UK trail begins at UK registration | Ask for the import paperwork and any overseas records. |
| A year or two with no test | It was declared off the road on a SORN, or simply went untested | Ask what happened in that period and look for invoices covering it. |
| Tests stop, then restart with a jump in mileage | Often a plate change, sometimes a genuine gap | Ask what registration the car carried before. |
| No tests after a certain year on an old vehicle | The keeper declared it exempt as a vehicle of historic interest | Expect no further mileage readings from that point on. |
| No record found for the registration at all | A typing error, a retained plate, or the wrong registration | Recheck every character against the V5C and the plate itself. |
Enter the registration and get the key facts before you commit to the car.

An imported car has no UK MOT history for the years it spent abroad, however well documented it was in Japan or Germany. The first UK test creates the first recorded reading, and everything before that has to come from paperwork the importer kept. Readings taken from a kilometre odometer add a second problem, because a conversion error at one test can look exactly like clocking at the next. An import check tells you whether the vehicle carries an import marker, which is a fact some sellers do not volunteer.
MOT history follows the vehicle record rather than the number plate, so a private plate going on or coming off usually carries the earlier tests across. Usually is not always. If the trail restarts abruptly, ask the seller what registration the car wore before and look that up too. A registration check and the V5C together will show whether a transfer happened and roughly when.
A registration that has moved more than once is not suspicious by itself. It matters because each move is a chance for part of the paper trail to be left behind, and because a cloned car often wears a plate that belongs to a similar vehicle somewhere else.
Pass and fail results age quickly. The odometer readings do not. Each test writes down a mileage that neither the seller nor the trade controls, so a run of tests builds the only independent mileage timeline most cars ever get. That is why a short history costs you something real. With three recorded readings instead of twelve, there is far less available to contradict the number on the dashboard.
A gap is not proof of anything. It is missing evidence, and missing evidence is a reason to pay less or look harder rather than to walk away on the spot. Ask for the years to be filled in from another source: service invoices, tyre or cambelt receipts, insurance documents, or dated photographs. If nothing exists for a long unrecorded period, price the car as though the mileage claim is unverified, because it is.
For an older car the sensible order is to read the free official record first, then run a full car history check for the things the MOT record cannot show, such as outstanding finance, write off markers and previous keepers. The two answer different questions and neither replaces the other.
Hidden finance and write-offs won't show up on a test drive.
