About This Statistic
This statistic shows the market share of grocers in Great Britain (GB) monthly from January 2015 to March 2017. Tesco and Sainsbury's had the largest share over the period under consideration, holding 43.7 percent of the market together as of March 2017. Prior to the popularity of the discounters, the grocery retail market was dominated by the 'big four' supermarkets: Tesco, Sainsbury's, Asda and Morrisons. On the back of the economic recession and growing inflation, however, consumer behavior has shifted in favor of cheaper alternatives and discounter stores. The resulting 'price wars' has led to supermarkets lowering their prices and the highest share of food volume sales on promotion in Europe. Crucially, this has caused increased volatility in the grocery retail market and, as of January 2017, Aldi overtook the Co-operative to become the fifth largest supermarket in the United Kingdom.
