Ocado has recorded in its quarterly sales as the grocery etailer says it will add ‘many more lines’ to its M&S range than the 4,000 product lines currently offered via Waitrose.

The grocery etailer posted a 10.8% uplift in retail revenue to £429.1m in the 13 weeks to December 1, bolstered by a 10.4% boost in average orders per week.

Average basket size was flat year-on-year at £104.90.

Ocado completed its range review of M&S products during the period as part of its newly-formed joint venture with the beleaguered department store chain. The grocery etailer confirmed it has secured substitutes of matching or lower prices for the majority of the 4,000 products currently supplied by Waitrose.

The retailer, which has a 55,000 strong product range overall and is set to go live with its M&S offer next September, said it “anticipates adding many more additional M&S lines to the range” than those currently offered by Waitrose.

Ocado said its Erith customer fulfilment centre continues to ramp up an ended the financial period processing over 70,000 orders per week.

Retail chief executive Melanie Smith said: “I am pleased to report further progress in bringing the Ocado offer to an ever-increasing number of customers in the U.K. Another strong quarter for customer orders means that we remain the fastest-growing grocer in the country. The collaboration between M&S and Ocado Group is working well.

“We have made good progress preparing for switchover date in September 2020, when the M&S food range will be available online for the first time. We are also planning fresh capacity, to offer customers more availability, and have new customer fulfilment facilities in Bristol and Purfleet, and a rebuilt state of the art facility at Andover, on the way. As a team, we could not be more excited.”
