Asda has added 250 new chilled home delivery vans to its fleet as it looks to boost online sales and lessen its reliance on large stores.

The delivery of the vans marks the first instalment of an order of 700 in 2012 that will bring the retailer’s home shopping fleet to over 1,600 vehicles nationwide.

Forty of the new vehicles are already operating from Asda’s new home shopping centre in Nottingham, which officially opened on 19 February.

CEO Andy Clarke recently conceded that Asda’s underwhelming 0.1% growth in like-for-like sales in Q4 was chiefly down to its out-of-town estate. “Large stores have not been performing as well as small stores, and Asda has the largest store sizes by far,” he said.

The 3.5-tonne Iveco Daily vans will provide four years of service, seven days per week.

Iveco has supplied all of Asda’s new home delivery vans since 2011, following a trial of 50 of the Daily vans in 2010.

“On the strength of its performance then and projected whole life costs, we’ve been steadily growing our fleet ever since,” said Sean Clifton, Asda’s grocery home shopping fleet contract manager.
