MOT results for every model

UK figures to the end of June 2026, and to the end of 2025 for year built and engine size. Updated 9 November 2026.

Figures cover the United Kingdom. Quarterly history before 2014 Q3 covers Great Britain only, because the UK figures start then; Northern Ireland adds a few percent from that point. SORN (off-road) counts are only available from the end of 2007. Older vehicles often have no model recorded by DVLA, so counts for classic models are likely to be low.

MOT figures: initial MOT tests in Great Britain during 2025. Cars under 3 years old don't need an MOT, and most cars over 40 are exempt, so older models are represented by the owners who choose to test. MOT records can't separate car and van versions of the same model.
