Most drivers glance at the pass/fail result and file their MOT certificate away without reading it. That’s a mistake. The certificate contains information that directly affects your car’s value, your insurance, and what you should be fixing before your next test.
What document will you receive? If your car passes, you receive a VT20 certificate. If it fails, you receive a VT30. Both are issued digitally through the DVSA system, and your garage should give you a printed copy or email a digital version.
The registration number and vehicle details Check that the registration number, make, model, and colour match your vehicle exactly. Errors here are rare but worth catching — a certificate issued against the wrong registration provides no legal cover.
Test date and expiry date Your new MOT is valid for 12 months from the test date — not from the date your previous MOT expired. If you tested early, you keep the time remaining on your old certificate only if the test falls within the one-month early window.
Mileage recorded The odometer reading at the time of test is recorded and stored in the DVSA database. This is the figure that makes mileage fraud detectable when you run a vehicle history check. If the mileage at your next test is lower than this figure, the DVSA will flag it.
Failure items (VT30 only) The VT30 lists every defect that caused the failure, categorised as Dangerous or Major. Dangerous items mean the vehicle should not be driven at all. Major items mean it cannot be driven until repaired, except to travel to a pre-booked retest at the same garage.
Advisory notes Advisory notes appear on both pass and fail certificates. They list items the tester spotted that were not serious enough to fail the vehicle but which need attention. They are not legally binding — you are not required to fix them before the next test — but ignoring the same advisory across multiple tests is a sign of neglect that could affect resale value.
The tester’s details The certificate shows the name and DVSA number of the approved tester who carried out the inspection. If you wish to challenge a result, this is the reference you’ll need.
