Common questions

What is the MOT pass rate in North West London?
76.3% of MOT tests in the North West London postcode area (NW) pass once results are adjusted for the age and mileage of the cars tested, which is well above the national average of 72.2%. The unadjusted figure is 78.7%. That ranks North West London 16 of 118 areas in England, Scotland and Wales.
What do cars fail on most in North West London?
The item recorded most often on failed tests in North West London is "Tyre tread depth not in accordance with the requirements", in 13.5% of failed tests, followed by "a brake lining or pad worn below 1.5mm" (11.0%). Corrosion-related items are recorded 0.0 times per 100 failed tests here, which ranks 106 of 118 areas for corrosion.
Does this mean garages here are stricter or more lenient?
No. The figure describes the cars tested in North West London, not the testers. Every MOT station applies the same inspection manual, and DVSA monitors testing standards nationally. A regional difference reflects the local fleet and local conditions — roads, weather, salt, how far cars are driven — rather than how hard the test is.
Is North West London a bad area to buy a used car from?
The area itself is not a concern. Corrosion is recorded less often on failed tests here than in coastal and northern areas, so a car from North West London is, on the evidence, less likely to carry rust problems than one from Scotland or the West Country. The individual car's MOT history still matters far more than its postcode.
