Asda is hoping to take on the might of Amazon with the launch of a one-hour grocery delivery service – but each delivery will set you back £8.50.

The supermarket said it will become the first grocer to offer its full online product range, but the service is currently limited to three stores and only people in a couple of parts of the Bradford area can access it.

Customers living within a three-mile radius of its store in Halifax are part of the launch, which covers people living in Northowram, part of Shelf, Shibden and Southowram, and its Rotherham and Poole are also part of the roll out..

Rivals, including Bradford-based Morrisons, Tesco and Sainsbury’s already offer one-hour – or faster – delivery services through Deliveroo, Uber Eats, Amazon and other providers – although none offer a full range of products.

Shoppers can order up to 70 items and have them delivered within an hour, or buy an unlimited basket which can be delivered with a four-hour window, Asda said.

If popular, bosses hope to roll it out to more customers at other stores – although the £8.50 delivery fee may be prohibitive, with rivals charging far less for each delivery, albeit with fewer products to choose from.

The supermarket is also extending its partnership with Uber Eats from 200 to more than 300 stores, with 500 products including fruit, vegetables, beer, wine and spirits and meals for rapid delivery.

Simon Gregg, Asda’s vice president of online grocery, said: “After successfully trialling an Express Delivery service, we know this is something that our customers want as part of our online grocery proposition and we are delighted to be able to offer this service to even more customers.

“The launch of our new Express Delivery service and extension of our existing partnership with Uber Eats to 300 stores means that customers can get their order delivered to the doorstep at market-leading pace.”

Tesco started a Whoosh trial in Wolverhampton last year, while Sainsbury's runs its own Chop Chop app service - but that isn't available in Bradford yet.

Waitrose is partnering up with Deliveroo, and Morrisons has a partnership with Amazon to offer rapid same-day delivery.
