Discount supermarket Aldi has overtaken upmarket rival Waitrose to become Britain’s sixth largest grocer, industry figures have shown.
Aldi achieved a 5.3% market share in the twelve weeks to 29 March in the latest till roll figures from Kantar Worldpanel after boosting sales by 16.8% during the period.
This beats Waitrose, which had been the sixth largest grocer, which saw sales lift 2.9% to claim a 5.1% market share.
In a mixed bag for the big four supermarkets, Tesco continued to make gains under a turnaround by new boss Dave Lewis seeing sales grow 0.3% to give it a 28.4% share, while Sainsbury's lifted sales 0.2% to a 16.4% market share.
But Asda saw its sales fall 1.1% to give it a share of 17.1%, while sales at Morrisons fell 0.7% to a 10.9% market share.
Fraser McKevitt, head of retail and consumer insight at Kantar Worldpanel, said: "Aldi has recorded double-digit sales growth for the past four years and is now Britain's sixth largest supermarket with 5.3% of the market."
He said Aldi's growth had been fuelled by over half a million new shoppers visiting Aldi this year, with its average basket size increasing by 7%. But he added that although the grocer's rise was high compared to rivals, it was still slower than in recent times.
Discounters Aldi and Lidl have also been growing rapidly in the Irish market and held a 8.1% and 7.6% share of the market, respectively, by the start of March.
However they are still some way behind the traditional big three grocers, with Dunnes’ share the next largest at 23.4%.
