What the MOT record shows

No single area dominates — tyres (4.8%) and brakes (4.1%) are close, so failures are spread across several systems rather than one weak point.

At component level the recurring items are brake pads, wipers and headlamp aim — brake pads alone was recorded 689 times.

Condition tracks the odometer closely. Failures run at 8.0% in the 0-30k band and 16.4% in the 150k+ band, a 8.4-point spread — more than double.

Advisories point at the next bill rather than this one: tyres was flagged on 24.7% of tests without failing them.

The trend is worsening — 10.8% of tests failed in 2021 against 15.4% in 2025, the usual pattern as a fleet ages.
