The pressure on the big four grocers has intensified as Waitrose and Aldi notch up record market share figures yet again.
Tesco and Morrisons also experienced a sales drop.
Tesco’s share dipped 0.9 percentage points year on year to 28.7% while Morrisons dropped 0.7 percentage points to 11.1%.
Sainsbury’s was the only one of the big four grocers to hold its market share at 17% as sales edged up 2.2% over the period.
On the other end of the scale, upmarket Waitrose also notched up a record share of 5% as sales increased 6.2%.
Kantar Worldpanel director Chris Longbottom said: “Over the past three years Waitrose, Aldi and Lidl have taken a combined 3.5 share points from the competition which equates to £4.4bn per year. This has put pressure on the big four supermarkets to compete for a shrinking middle ground and cut prices to directly combat the discounters.”
Under pressure The Co-operative sales increased 0.7%. However it suffered a marginal drop in share from 6.2% to 6.1%.
The overall grocery market grew 2.2% over the period, representing a further slow down in growth from Kantar’s last reported sales period, which was the lowest since mid-2005.
Falling inflation is the main contributing factor for the stalling growth, Kantar found.
