Waitrose, Iceland and Marks Spencer have topped a Which? supermarket consumer satisfaction survey.
Shoppers gave Waitrose the award for best in-store experience, with Tesco and Asda trailing in eighth and ninth place respectively.
The consumer group said Iceland was voted best for online, closely followed by Ocado, with Morrisons in third.
The MS Simply Food chain won the convenience store category. Which? surveyed more than 7,000 UK shoppers.
Customers were asked to rate stores and online operations based on their experience in the past six months on categories such as quality, value for money, service from delivery drivers, how easy it was to find products, and whether shoppers would recommend the retailer to a friend.
Which? said customers were particularly happy with Iceland’s convenient delivery slots and friendly drivers, helping it to top the online category for the second year in a row.
The consumer group also said Waitrose’s helpful staff had won over shoppers in the in-store survey, with customers saying that its spacious store layouts made groceries easy to find.
MS came second in the in-store category, with Aldi and Lidl placed joint third.
Which? said Aldi and Lidl were fairly “evenly matched”, with both scoring particularly well on value for money.
Asda was at the bottom of the in-store table in ninth place, and was also joint last with Sainsbury’s and Waitrose in the online rankings.
Must do better
While Asda was seen by consumers as being generally good value, its food quality was rated as average.
Richard Headland, Which? magazine editor, said: “With concerns over rising prices the competition among supermarkets is fiercer than ever.
“While value for money remains a top priority, in-store appearance and the availability of quality and fresh products can also go a long way to satisfying shoppers’ need,” he said.
An Asda spokeswoman said: “We know that we need to do a better job for our customers and all our colleagues are working hard to make a real difference.
“We’re getting better every day and we are confident that customers will be pleasantly surprised if they shop with us today compared to when this survey took place last year – and we’ll be even better tomorrow.”
