Aldi, Lidl and Waitrose supermarkets increase market share
Discount and premium supermarket chains have continued to increase their market share at the expense of the main UK supermarket chains, research firm Kantar Worldpanel has said.
Aldi recorded a record gain of market share over the year, Kantar said, rising by more than a third.
Lidl and Waitrose also saw strong growth, it added.
Of the "big four" chains, Asda was the most resilient, while Morrisons lost the most market share.
Kantar looked at supermarket spending for the 12 weeks to 30 March, compared with the same period a year ago.
- Tesco remained the leading UK supermarket, with 28.6% of market share, down from 29.7% for the same period a year ago.
- Asda had 17.4%, Sainsbury's had 16.5%, and Morrisons had 11.1% of the market in the 12 weeks ending 30 March.
- The "big four" all experienced a drop in market share compared with the same period a year ago.
- Aldi's share of the market rose from 3.4% to 4.6%.
- Waitrose had 5% of UK sales in the in the 12 weeks ending 30 March 2014, compared with 4.8% in the same period last year.
Tesco, Asda, Sainsbury's and Morrisons all experienced a decline in sales. Nevertheless, Tesco still dominates the market with a 28.6% share, compared with 4.6% for Aldi.
Edward Garner, director at Kantar Worldpanel, said: "Amid a challenging market backdrop, individual retailer growth might be expected to be restricted.
"This is certainly not the case for Aldi, which achieved its highest ever growth of 35.3%, boosting the retailer to a record market share of 4.6%.
"Lidl also experienced strong growth in a record-breaking month and now accounts for 3.4% of the market."
Tesco, Sainsbury's, Asda and Morrisons have been dominant in the UK for some time.
However, in recent years, supermarkets at both the discount and premium ends of the market have reported strong growth.
