MOT pass rates in Slough

238,855 cars took a first MOT at test centres in the SL postcode area in 2025. The SL postcode area covers Slough and the towns around it — Windsor, Maidenhead, Gerrards Cross and Iver among them. How the cars did, what they failed on, and what the area drives — computed from the official DVSA record. Figures describe tests done in this area, wherever the cars live.

How Slough compares

Ranks and comparisons cover the 116 postcode areas with 20,000 or more first tests in 2025 — the full field at that floor; DVSA merges its smallest areas into one shared code, which is excluded. Location is always the test centre's postcode area, not where any car is kept. Ranks are unadjusted for the age and mix of each area's fleet — they say where an area sits, not why. Areas are often separated by a fraction of a year or a fraction of a point: each rank is exact on the data, but neighbouring ranks can be effectively level.

The area's signature make

Of the twelve most-tested makes at SL-area test centres, BMW is the one tested furthest above its national share: 8.6% of SL-area first tests against 5.7% of tests nationally — 1.5 times its national rate. That is a fact about what the area drives, not a claim about the make.

Better or worse than the national average?

The SL area's pass rate minus the national pass rate at each car age, in percentage points. Bars above zero: SL-area tests beat the national average for that age. Below zero: they trail.

Source: DVSA Active MOT test stations (Open Government Licence v3.0), release of 26 February 2026. Listing here means DVSA approves the station for the classes shown; it is not a recommendation, and we publish no per-garage pass rates. Some stations are sole traders, so an address may be a home address — we show it because DVSA publishes it as the approved test site. Run a test station and want your entry corrected or removed? Email [email protected] and we will act within 7 days.

How these figures are computed. Every number on this page is calculated by SortedCars from the DVSA anonymised MOT results dataset (every MOT test in Great Britain — 2025 for single-year figures; trend figures state their span, currently 2023–2025). Where a figure comes from a sample or uses banded values (mileage is banded to 2,500 miles), the page says so beside the figure. Test class 4 only, first tests only — retests are excluded. Class 4 is the car MOT class and also covers car-derived vans, pickups and motorhomes tested to the same standard; where this page says "cars" it means class 4. Pass rate = passes ÷ (passes + failures + pass-after-rectification): a vehicle that failed and was fixed during the visit counts as a fail. Pass rates describe fleets, not individual machines: they reflect how cars were driven, maintained and used as well as how they were built, and beyond recorded mileage none of that is in the data. A well-kept example of a model with a weak average can still pass; a neglected example of a strong one can still fail. No figure is shown for any group with fewer than 500 tests. Location is the test centre's postcode area, not where any car is kept. Alias spellings of a make in the DVSA file are counted under one make name, using SortedCars' grouping tables. “Dangerous” is DVSA's statutory defect category (in force since May 2018): a defect posing an immediate risk to road safety — driving the vehicle before repair is an offence. What these figures are for. These statistics are general information about groups of vehicles. They are not advice, a valuation or a recommendation to buy, avoid or price any particular vehicle, and no decision about one car should rest on them alone — check the car itself and its own records. We take care over the calculations, but we cannot guarantee they are complete, current or free of error, and we accept no liability for loss arising from reliance on them. This does not limit any liability that cannot lawfully be limited — see our Terms & Conditions. If you believe any figure on this page is inaccurate, contact us. SortedCars is not affiliated with, or endorsed by, the DVSA or DVLA. DVSA publishes the raw test records; the statistics on this page are SortedCars' own calculations from them.
