The service gives customers access to Asda’s full online range of more than 30,000 grocery products for delivery within one hour if they live within a three-mile radius of an Express Delivery store and order up to 70 items.

The decision to expand its one hour delivery offering comes after a successful initial roll out to a couple of the company’s existing stores which saw higher than anticipated orders through the service.

The grocery store intends to launch Express Delivery in more stores, if the latest rollout proves to be successful.

Simon Gregg, Asda’s Vice President of Online Grocery said: “We are rolling out our Express Delivery service to almost 100 stores after a trial showed there was a clear gap in the market for a speedy delivery service offering our full online product range for delivery within one hour.

“We anticipate more demand for this flexible service now that many of our customers have returned to their place of work and children are back at school.”
