Aldi and Lidl have posted record market share according to the latest data from Kantar Worldpanel.

Aldi recorded share of 3.4% in the 12 weeks to 14 April, up from 2.7% in the same period the year before. Lidl’s market share increased from 2.8% a year ago to 3%.

Aldi also chalked up its highest-ever sales growth during the period – of 31.1%.

“Pressure on household budgets is undoubtedly driving some of the growth at the discounters, but messages about quality are starting to resonate,” said Kantar Worldpanel director Edward Garner.

“Lidl announced this week that it will increase its fresh meat and poultry floor space by 50% within the year, and Aldi’s new ‘convenience’ store in Kilburn [pictured] is a departure from its traditional edge-of-town offering. These changes are likely to appeal to a new and different group of shoppers which will bolster the performance of the discounters even further.”

Away from the discount sector, Waitrose continued its strong run with sales growth of 12% in the 12 weeks to 14 April and a record market share of 4.9%.

Sainsbury’s continues to lead the big four with sales growth of 5.4%, ahead of Asda (3%), Tesco (1%) and Morrisons (0.3%).

Despite recording positive sales growth in recent months, The Co-op saw sales fall 1.8% during the period.
