MOT pass rate in London (NW)
MOT pass rate in London (NW): 86.8% of MOT tests on cars tested here passed.

That ranks 14 of 118 postcode areas (1st is highest). The raw rate is the one you notice; the adjusted rate is the one that means something.

What an MOT failure costs here
Across the 692,347 tests in this area, the typical bill works out at £422 to £1,130 per 100 tests, against £615 to £1,675 nationally — 10 of 118 areas, cheapest first. That is the pass rate and the price of the parts that fail here, multiplied together, so it moves with both.
Bands are our parts-based estimates, not quotes: how repairs are priced. The models that cost most to fix are on the cheap-and-dear list, and how far apart two postcodes can be for one model is worth a look before blaming the car.
One model year, this area against the rest
The tables below compare the same model year in this area with the same model year everywhere, so vehicle age is taken out of the comparison entirely. Each row links to that model's full postcode-by-postcode breakdown.
| Model | Here | Gap |
|---|---|---|
| Peugeot 208 | 77.3% | -4.3 |
| Volkswagen Up | 85.1% | -1.9 |
| Ford Ecosport | 85.3% | -1.7 |
| Peugeot Expert | 97.6% | +18.9 |
| Peugeot Partner | 89.2% | +11.4 |
| Toyota Corolla | 95.5% | +11.1 |
Furthest behind: Peugeot 208, Volkswagen Up, Ford Ecosport. Furthest ahead: Peugeot Expert, Peugeot Partner, Toyota Corolla. “Gap” is against each model's own national rate, not the 81.0% all-car rate — method. Three models either side of the gap, and each needs at least 300 tests of that model-year in this area.
Models that do worst here
| Model | Local | Nationally |
|---|---|---|
| Peugeot 207 | 76.8% | 70.8% (+6.0) |

MOT stations in NW
There are 114 MOT test stations licensed for class 4 vehicles (cars, vans, motorhomes and people carriers) in the NW postcode area, according to the DVSA's published list of active stations.
We deliberately do not rank garages. The anonymised MOT data has no test-station field, so any “best garage in London” list would be invented rather than measured — and a garage's pass rate mostly reflects the cars its customers bring, not the quality of its work.
Test centres by town in NW
Each town below has eight or more licensed class-4 stations and its own page: names, addresses, phone numbers and the postcodes they cover.
How to read this
The rate is per test, not per car: a vehicle tested twice counts twice, and a car that fails and is retested for free contributes a fail and a pass. The adjusted rate gives every area the national mix of model years and mileage bands by direct standardisation, so the “old cars” explanation is removed from the comparison — the full method.
Postcode area is the keeper's registered area, not the test station's. These are regional signals, not neighbourhood ones.
