Used diesel sales took a hit in Q2 with volumes “falling sharply” behind recent years.
According to Marketcheck data, a total of 382,350 used diesel vehicles were sold between April and July 2026.
That compares with 438,421 during the same four-month period in 2025 and 422,828 in 2024.
Alastair Campbell, MarketCheck UK, said: “The interesting thing about diesel this summer isn’t necessarily the movement from one month to the next, but the gap that’s opened up compared with recent years. The slowdown is noteworthy and considerable.
“It will be interesting to see whether volumes recover as we move out of the summer or whether 2026 marks the beginning of a more sustained reduction in used diesel transactions.
