The research, data and insight company said the results helped the grocer to achieve a new “record high” market share of 8%, and some 13 million households visited Aldi at least once in the past 12 weeks.
It added that London holds “potential for Aldi”, as both its fastest growing region and where its market share is currently lowest, going some way to explain the recently announced trial of the smaller Aldi Local format in the capital.
Lidl was the second fastest growing supermarket, with sales increasing quicker than last month at 5.8% and market share growing by 0.3 percentage points to 5.6%. However, Tesco grew by 0.5% to achieve market share of 27.4%, 0.2 percentage points lower than a year ago.
A statement from Kantar read: “The figures, published today from Kantar, show year-on-year supermarket sales growth of 1.4% during the 12 weeks to 24 March 2019.
“This year’s late Easter, and the fact that Mother’s Day falls outside the reported period, contributed to the market growing at its slowest rate since March 2018 and trimmed an estimated 0.5 percentage points off the overall growth rate.”
