Frequently asked questions
Why do pass rates differ between areas?
Vehicle age is the biggest driver — areas with older cars fail more often — along with mileage patterns, road conditions and local incomes. The test itself is the same everywhere, and the fee is capped by law at £54.85 for a car.
Does this mean garages in Hounslow are stricter?
No — these figures reflect the vehicles being tested, not tester behaviour. Wherever you test, the same DVSA inspection manual applies.
Where does this data come from?
DVSA's anonymised MOT results for 2025 (Crown copyright, Open Government Licence v3.0), aggregated by the postcode area of the test station. See the full methodology.
