Aldi and Lidl have emerged as surprise successes in the latest annual survey of customer satisfaction carried out by Which? magazine.

Waitrose again topped the list, with a score of 85%, comfortably ahead of Marks & Spencer (68%) in second.

The German discounter duo of Aldi and Lidl were respectively third and fourth in the rankings, ahead of the UK’s big four supermarkets. Both discounters scored maximum ratings on pricing in the survey, which saw more than 12,000 shoppers take part.

“Offering shoppers brand quality products at everyday, exceptionally low prices is at the heart of what Aldi does,” a spokesman for the discounter said.

“Our five-star rating for pricing by Which? members proves that our shoppers see the benefits of this. We are confident these results will attract new shoppers into our stores to see how much they can save.”

Bottom of the table was The Co-operative Group, which scored just 46%.
