Tesco is the UK's largest retailer, and one of the largest in the world. It opened its first store in north London in 1929, and there are currently more than 3,400 Tesco branches in the UK. But are they any good?
In the annual Which? supermarkets survey, almost 5,000 Tesco customers rated the retailer on everything from queuing time to the quality of its food and value for money. This enabled us to work out star ratings for different factors as well as an overall customer score.
As well as accessing the supermarket scores, logging in or joining Which? will enable you to see how Tesco fared when we reviewed items from champagne and cheese to washing-up liquid and dishwasher tablets.
Tesco has existed in various guises over the past few years. As well as standard supermarkets, there are smaller Tesco Metro and Tesco Express stores, and larger Tesco Extra superstores, which stock a wider range of non-food items.
In September 2018 the company also launched a new cut-price retail brand called Jack's to compete with discounters Lidl and Aldi. However, one of the the first branches that opened - in Rawtenstall, East Lancashire - was converted back to a regular Tesco store in late 2019, apparently due to customer demand.
Tesco Direct, the retailer's non-grocery website which was originally built to compete with Amazon, closed in summer 2018.
In 2019, Tesco announced that it would close the fishmonger, butcher and deli counters in 90 of its larger stores and reduce the number of layout changes it makes, estimating that 9,000 Tesco staff roles could be affected by this. In early 2020 it also announced 1,800 jobs were likely to be cut in its bakeries.
Tesco is keen to focus on customer loyalty and launched its Clubcard Plus subscription service in the autumn of 2019. For £7.99 a month, shoppers get 10% off two big food shops (in-store only), money off a range of non-food brands and double data on Tesco Mobile among other offers.
