Supermarket chain Sainsbury has the fastest growing online grocery business in the UK and has now become the second largest in the market, according to new trading figures published today.

A 20 per cent rise in online orders means that it is now receiving more than 165,000 a week, meaning annualised turnover for Sainsbury.co.uk is now an estimated £750 million, behind only market leading rival Tesco.

In general market terms Sainsbury‘s still ranks third behind Tesco and Asda, but the grocer has been making gains on it rivals during the last year and its success online will encourage the business that it can grow further in the coming months.

John Rudoe, Director of Online at Sainsbury‘s, said: “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.

“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.”

Sainsbury‘s recently commissioned research firm Ipsos Mori to survey online grocery shoppers to measure customer service levels at its online store in comparison to Tesco, Asda, and online-only firm Ocado.

In each of the five categories Sainsbury‘s came out on top, according to Ipsos Mori; scoring highly in quality of products; availability of delivery slots; customer service from delivery person; speed of placing an order; and contact centre staff.
