What the MOT record shows

One area stands out: lighting & signalling, recorded in 20.4% of tests against 11.2% for the next-worst category.

At component level the recurring items are headlamp aim, catalyst emissions and washers — headlamp aim alone was recorded 477 times.

A 150k+ example is materially riskier than a 0-30k one: 37.8% versus 22.8%.

Brakes is the most common advisory, noted on 34.5% of tests — work that passed today but is likely due soon.

The trend is improving — the fail rate fell from 29.3% in 2021 to 27.2% in 2025, as the worst-kept examples leave the fleet.
