Greenford (Horsenden Lane) test centre: 41.4% pass rate, £575 to get through it.

Over 2025/26 the examiners at Greenford (Horsenden Lane) conducted 7,222 car practical tests and issued 2,992 passes. The resulting 41.4% makes it a mid-sized centre sitting 288th of 308 on the national pass-rate table and 23rd of 26 in London.

That is 8.6 percentage points below the 50.03% national figure, and 7.3 points below the 48.8% average for London. Low pass rates cluster where test routes carry heavy traffic, multi-lane junctions and frequent bus lanes. The examiners are not stricter; the roads give a candidate more chances to make a serious fault.

Turn 41.4% into money. One divided by the pass rate gives 2.41 expected attempts before a first pass, so the average candidate at Greenford (Horsenden Lane) pays the £62 weekday DVSA fee about 2.41 times, or £150. Add 1.41 expected retakes at 7 hours of extra tuition each, charged at the London rate of £43 an hour, and the extra lessons come to £426. The test cycle at Greenford (Horsenden Lane) is therefore about £575. Testing here therefore costs about £150 more than the same candidate would spend at a centre sitting on the 50.03% national average, purely because of the extra attempt the pass rate implies.

Waiting time at Greenford (Horsenden Lane) ran to a median 10.7 weeks between booking and test in July 2026, 1.2 weeks below the 11.9-week national median. Across 1.41 expected retakes that is roughly 15.1 weeks of extra queueing before a licence arrives. In the same month DVSA offered 1,207 standard slots inside the booking window here and 3.8% of them were still free to book.

The first-attempt picture is harder here than the headline. 3,388 candidates sat their first test at Greenford (Horsenden Lane) and 1,355 passed, 40.0%, which is 1.4 points below the all-attempts rate. 36 of those first tests were passed with no driving faults recorded at all, 1.06% of them. Budget for the second booking from the start rather than treating it as the exception.

Since 2021/22 the pass rate at Greenford (Horsenden Lane) has risen by 2.8 points, from 38.6% to 41.4%. Volume has been steady, 6,703 tests then against 7,222 now. On the cost model above, that shift alone is worth about £63 to the average candidate.

Male candidates passed at 44.0% and female candidates at 36.9%, a gap of 7.1 points across 4,599 and 2,623 tests. Automatic tests accounted for 45.0% of the 7,222 tests and passed at 41.0%, close enough to the overall rate that gearbox choice is a comfort decision here, not a pass-rate one. Month to month the rate ran from 38.0% in March 2026 to 43.7% in July 2025, a 5.7-point swing that shows how little a single month proves.

Among centres of a similar size in London, Yeading (London) runs 11.4 points higher at 52.8%. On the same arithmetic that is roughly £188 of expected difference. Before moving, price the switch: a new instructor or extra travel for route familiarity typically costs £60 to £120 plus two settling-in lessons, which eats most of a gap under about eight points.
