Sainsbury’s is now the UK’s second-biggest online grocer, the supermarket has claimed, after its orders topped 165,000 a week.

The supermarket’s online grocery business has increased sales by 20% a week year-on-year, with an annualised turnover of more than £750m.

Sainsbury’s also came out top in a new Ipsos Mori online survey. The retailer ranked first on quality of products, availability of delivery slots, customer service from the delivery person, speed of placing an order and contact centre staff.

“Thousands of new customers are choosing Sainsburys.co.uk each week because it’s simple to use and like our stores, people are assured of the service they’ll receive,” said Sainsbury’s director of online Jon Rudoe.

“We’re proud of our successes so far, but it doesn’t stop here, we’ve got ambitious growth targets which we’ll reach by continuing to deliver the best possible experience for our loyal and new customers.”
