Cars tested in the NP postcode area fail first time 31.5% of the time, against 28.2% nationally, so 3.3 points worse than average. Tyre tread below the legal minimum heads the local list, on 12.02% of failed tests, with a broken coil spring close behind. The figures come from 850,609 DVSA test records for the area.
Bars show how often each defect appears on failed tests in this area. The figure in italics is the difference from the national rate for that defect.
A tyre fail usually means a tyre that was already an advisory last year. Worth looking at the previous certificate before booking. The UK-wide failure figures show the same pattern, and our advisory conversion table puts a number on how often a noted item fails the following year.
An MOT in Monmouth costs anything up to £54.85 for a car, the legal maximum. Cheaper tests are common and the test is identical wherever you go: same checklist, same DVSA standards, same certificate.
Demand peaks in March and bottoms out in December, a swing of roughly 60%. The peaks follow the March and September plate changes three years earlier, when new cars reach their first test.
If the car fails and you leave it at the station for repair, the retest is free. If you take it away, a partial retest within ten working days at the same station is free for a list of minor items such as lamps, wipers, mirrors, seatbelts and tyres, and charged at a reduced fee for anything else. After ten days it is a full test again.
The law allows one journey without a certificate: to a booked MOT, or to repairs arising from one. Keep the booking confirmation with you, and remember that insurance is still required and a dangerous defect still makes the car illegal to drive.
If none of the Monmouth stations suits, these neighbouring towns are a short drive away: Newport test centres (83), Coleford test centres (6), MOT in Usk (5), MOT in Chepstow (6), MOT in Lydney (8) and MOT test stations in Caldicot (11).
Your last certificate's advisories are the likeliest failures this time. A free MOT history check shows them in seconds, together with the pass rate for your exact model and year. For the cars tested most often in Britain, see the Toyota Yaris reliability, what fails a Volkswagen Polo and Ford Transit reliability pages, each built from the national dataset.

March is the busiest month for MOT tests in the NP postcode area, and December the quietest. Stations fill up two to three weeks ahead in the peak months, so book early if your certificate expires then.
