Aldi has posted record sales growth figures

Three of the biggest discount supermarkets in the UK are celebrating after recording strong sales growth.

Lidl and Farmfoods grew their sales year-on-year in the 12-week period to 15 September by 14.3 per cent and 25.8 per cent, respectively, while Aldi posted record-breaking sales growth figures of 32.7 per cent.

Aldi also grew its market share to 3.7 per cent, compared with 2.9 per cent during the same period in 2012.

Tesco, though, saw its market share slip from 30.9 per cent a year ago to 30.2 per cent, although the retailer grew its sales by 1.9 per cent.

Asda also grew its sales by 2.4 per cent in the 12 weeks to 15 September, while its market share was squeezed from 17.6 per cent to 17.3 per cent.

Sainsbury's, meanwhile, grew sales by 5.1 per cent during the same 12-week period, and increased its market share to 16.6 per cent (up from 16.4 per cent a year ago).

Waitrose grew its sales by 9.7 per cent, and marginally increased its market share to 4.9 per cent.

And Morrisons and The Co-operative Group also reported positive sales growth figures, 1.6 per cent and 0.3 per cent respectively. Both supermarket chains did see their market share fall, though.

The figures were compiled by market research firm, Kantar Worldpanel.

'The combined growth of Lidl, Aldi and Waitrose has taken three market share points out of the grocery market over the past three years, and is forcing the major supermarkets to compete for an even smaller middle-ground,' Edward Garner, Kantar Worldpanel director, said.
