Since its first store opened in London in 1869, Sainsbury's has grown to become the second-largest supermarket in the UK. But is it any good?
Sainsbury's has almost 600 supermarkets and more than 800 smaller convenience stores, branded as Sainsbury's Local.
In the annual Which? supermarkets survey, more than 5,000 Sainsbury's 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.

Sainsbury's in the news
Although its experimental till-less store in central London ultimately failed, with checkouts being reinstalled in September 2019, the supermarket giant clearly hasn't been put off testing new concepts.
Sainsbury's announced in February 2020 that it was launching a new 'on the go' concept shop, again in central London, where customers could eat in-store, collect online Argos and Tu orders, and - you guessed it - pay via the app.
A proposed merger between Sainsbury's and Asda was blocked by the Competition and Markets Authority early in 2019.
