LONDON (Reuters) -German-owned discounter Aldi has overtaken Morrisons to become Britain’s fourth-biggest supermarket group, helped by its popularity during the cost of living crisis, industry data showed on Tuesday.
Market researcher Kantar said Aldi’s sales increased 18.7% over the 12 weeks to Sept. 4, taking its UK grocery market share to 9.3% from 8.1% a year ago. Morrisons’ sales fell 4.1%, with its share falling to 9.1% from 9.8%.
Aldi trails market leader Tesco, Sainsbury’s and Asda.
Aldi and fellow discounter Lidl account for 16.4% of the market and continue to open new stores.
Morrisons had been No. 4 since it took over Safeway in 2004. It has been owned by U.S. private equity firm Clayton, Dubilier & Rice (CD&R) since October.
“Back at the start of the 2010s, Tesco, Sainsbury’s, Asda and Morrisons together accounted for over three quarters of the sector, but that traditional Big Four is no more,” said Kantar’s Fraser McKevitt.
Morrisons said that market share is partly a function of new store openings, noting that it had not added any significant space for a while.
“Customers don’t really care about market share statistics; they care about value, quality, provenance and service – and that is where our focus is going to remain,” a Morrisons spokesperson said.
Kantar said that grocery inflation hit 12.4% in the four weeks to Sept. 4, another record, adding 571 pounds ($670) to the average annual grocery bill.
It said that products such as milk, butter and dog food were jumping up particularly quickly at 31%, 25% and 29% respectively.
Total grocery sales by value rose 3.8% in the 12-week period, Kantar said, with sales of the cheapest own-label products up by a third compared with a year ago.

Market share refers to the percentage of an industry's sales that a particular company controls. It is a measure of a company's competitiveness and market position within its industry.
Grocery inflation is the rate at which the prices of grocery items increase over time. It reflects changes in the cost of food and household products, impacting consumers' purchasing power.
A supermarket chain is a group of supermarkets owned and operated by the same company. They typically offer a wide range of food and household products under one roof.
Grocery market share indicates the portion of the total grocery sales that a specific retailer captures within a defined market, reflecting its competitive strength and consumer preference.
