Respondents were asked to rate their supermarket experience on several aspects including appearance, layout, quality of produce, availability of online delivery slots and value for money.
The German discount store topped the poll as the best in-store supermarket in the UK after it was the only chain to achieve a five-star rating for value for money.
The store only gained two stars for the layout of the supermarket and the quality of the food, but shoppers said that price was the most important factor to consider when choosing where to shop, with one satisfied customer adding: “Excellent. Local and convenient, stock range is limited but I love this as you’re not spending loads of time making decisions on what brand to buy.”
M&S came second in the results with a five-star rating for the quality of its fresh produce and own-label products. The supermarket also received top marks for the overall appearance and layout of its stores.
In the poll, Sainsbury’s was revealed to be the top-ranking online supermarket with an overall score of 71 per cent and a four-star rating for the availability of home delivery slots.
Ocado dropped to joint-fifth place, sharing the spot with Waitrose and Morrisons, after receiving a two-star rating for value for money and availability of home delivery slots.
Bottom of the in-store shopping charts, with a one-star rating for value for money and two-stars for food quality and store layout, was Co-op.
Which? Magazine Editor, Harry Rose, commented: “Many households have felt the pinch during the pandemic and value for money was the most important factor when shopping in-store in our annual supermarket survey, which explains why Aldi came out on top.
“Online supermarkets have also been a lifeline for many people during the pandemic and while Sainsbury’s rose to the challenge by massively increasing its delivery capacity, Ocado’s reputation took a hit after the scale of demand meant it stopped accepting new customers and shut down its app at the height of lockdown.”
