New light commercial vehicle registrations in the UK in August 2018 rose 5% year on year to 16,394 units.
The Society of Motor Manufacturers and Traders (SMMT) noted an "uplift in demand" for popular large vans (14.6%) and pickups (21.4%) which offset declines for medium (29.7%) and smaller (9.3%) models.
Large models accounted for 67.2% of all van registrations.
Yeartodate registrations were down 2.2%, with 220,399 new LCVs going on to UK roads so far this year, as fluctuating registrations caused by variations in fleet buying cycles and business confidence continue to affect the market.
SMMT chief executive Mike Hawes said: "August is typically one of the quietest months for new LCV registrations, so the increase in demand for these high tech, ultra low and zero emission vehicles is especially welcome news. While year to date figures show the market remains at a reasonably high level, weak business confidence and uncertainty means fluctuations in demand will likely continue throughout the year."
