Supplies of good quality vans remain limited and competition from buyers for the best examples remains intense.
Year on year figures show values have improved significantly even with age and mileage rising, according to BCA Pulse.
Year-on-year, April 2012 was 7.6% ahead of the same month in 2011, despite the average age climbing by six months to 57 months and average mileage being 5,500 miles higher at 78,000.
Performance against CAP also improved year-on-year, up nearly one and a half points.
April values were identical to those recorded in January and are the highest in two years.
This is despite average age and mileage rising and further underlines the shortage of stock as buyers are paying more in 2012 for older, higher mileage vans than they were a year ago,” said Duncan Ward BCA general manager commercial vehicles.
BCA said used LCV values rose 1% to hit £4,271 in April compared to March.
Looking ahead Ward said: “Previous years suggest the summer months are relatively flat, with a significant spike in values in the early autumn. The difficult economic conditions mean that many businesses may defer changing their vehicles until there are signs of improvement.
“Countering this, many new small businesses and sole traders are starting up and a van is often one of the first things on the shopping list.”
