Common questions

What is the MOT pass rate in Chelmsford?
74.7% of MOT tests in the Chelmsford postcode area (CM) 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 75.7%. That ranks Chelmsford 30 of 118 areas in England, Scotland and Wales.
What do cars fail on most in Chelmsford?
The item recorded most often on failed tests in Chelmsford is "A tyre seriously damaged", in 12.7% of failed tests, followed by "A spring or spring component fractured or seriously weakened" (10.5%). Corrosion-related items are recorded 0.0 times per 100 failed tests here, which ranks 114 of 118 areas for corrosion.
Does this mean garages here are stricter or more lenient?
No. The figure describes the cars tested in Chelmsford, 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 Chelmsford 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 Chelmsford 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.
