Over half of the UK’s households have visited either an Aldi or a Lidl in the last 12 weeks, data from Kantar Worldpanel showed today (17 December), underlining the inroads the discounters have made into the country’s grocery market.

Some 50.1% of all British households stepped into one of the two retailers in the 12 weeks to 8 December, compared with 46.1% a year ago, Kantar said.

During the period, each of the UK’s five largest grocers – Tesco, Asda, Sainsbury’s, Morrisons and The Co-operative Group – lost market share.

The data, which includes the impact of store openings, showed Aldi and Lidl enjoyed a record share of the UK grocery sector during the period. Aldi accounted for 4% of the market, while Lidl retained its record share of 3.1% which it reached during the summer.

“Both Aldi and Lidl have continued to record double-digit growth and are successfully broadening their shopper base with half of all British households visiting one of them during the latest period,” Kantar Worldpanel director Chris Longbottom said.

Of the Big Four, Tesco accounted for 29.9% of sales in the 12 weeks to 8 December, down from 30.6% a year earlier. Asda’s share was 16.9%, down from 17.3%. Sainsbury’s was close behind at 16.8%, versus 17% a year earlier. Morrisons’ market share was 11.6%, compared to 11.6% a year ago.
