Data: Worldpanel grocery market share

Worldpanel compiles its monthly snapshot of the UK grocery market by analysing the household grocery purchasing habits of 30,000 British households. The data Worldpanel collates is based on the value of the items purchased by those consumers. Tesco holds a strong advantage as Britain’s largest grocery retailer, with Sainsbury’s, Asda and Morrisons making up the so-called ‘big four’. However, value players Aldi and Lidl have closed the gap to the established order considerably having grown their respective market shares at a pace following the 2008 financial crisis. The discount duo hope to make further gains in the post-covid-19 recession.
