Common questions

What is the MOT pass rate in South West London?
75.4% of MOT tests in the South West London postcode area (SW) pass once results are adjusted for the age and mileage of the cars tested, which is above the national average of 72.2%. The unadjusted figure is 77.2%. That ranks South West London 21 of 118 areas in England, Scotland and Wales.
What do cars fail on most in South West London?
The item recorded most often on failed tests in South West London is "A tyre seriously damaged", in 11.7% of failed tests, followed by "Wiper blade missing or obviously not clearing the windscreen" (10.4%). Corrosion-related items are recorded 0.0 times per 100 failed tests here, which ranks 109 of 118 areas for corrosion.
Does this mean garages here are stricter or more lenient?
No. The figure describes the cars tested in South 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 South 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 South 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.
