Sainsbury’s has grown its market share by 0.3% over the past year to 16.5%, making it the “star performer” in Kantar Worldpanel’s latest supermarket share data.

The major multiple delivered growth of 5.6% for the 12 weeks to 30 September, while discounter Aldi achieved a whopping 25.4% rise, to reach a market share of 2.9%.

Just ahead of Aldi in the table was Waitrose, which posted a record supermarket share of 4.7%.  
Asda added 0.1 share points to reach 17.5%, while Tesco and Morrisons both lost share over the 12-week period, down 0.2% and 0.4% respectively.

Edward Garner, director at Kantar Worldpanel, said: “Among the big four supermarkets, the stand-out performance is from Sainsbury’s. Its sponsorship of the Paralympic games has clearly borne fruit, boosting its sales in this period.

“The retailer has also been bolstered by its Brand Match promotion and the ongoing relaunch of its own-label range – both of which are proving popular with consumers.”

The overall grocery market is growing at 3.9%, according to Kantar, which is above the market research company’s inflation measure of 2.6%. It said this meant there was currently “real growth in the market”.
