'˜Big shop' at Aldi and Lidl £15 cheaper than big four supermarkets, figures show

The average cost of grocery trips for at least 20 items ranges from £31.28 in bargain stores such as Poundland, B&M and Home Bargains to £58.85 in Waitrose, according to data from analysts Nielsen.

The average spend on the big shop at discounters Aldi and Lidl is £38.76, compared with £53.16 across the big four - Tesco, Asda, Sainsbury’s and Morrisons - and £58.52 across Waitrose and M&S.

Nielsen’s UK head of retailer and business insight, Mike Watkins, said: “In simple terms, a big shop at the discounters is nearly £15 cheaper than one at the Big Four and £20 cheaper than at Waitrose and M&S.”

The figures, based on Nielsen’s Homescan data, which measures purchasing by 15,000 British households, show that shoppers are making more frequent, smaller grocery trips alongside the big shop.

Small purchases - baskets of fewer than six items - account for 53% of grocery trips, while medium trips for six to 20 items make up 34%.

Consumers make 5% more grocery trips than they did two years ago, resulting in the average amount spent on the big shop dropping 5% to £50.58.

Mr Watkins said: “The move to ‘little and often’ is a symptom of busier and more time-pressured lifestyles as well as financial concerns of wasting food.

“Thus, supermarkets have made huge investments in the convenience store format to meet this demand and offer a greater variety of food and drink. Their historical role for purely immediate or ‘distress’ purchasing is long gone.”

Aldi and Lidl’s share of big shop trips is now 13%, and Nielsen predicts that this will more than double within five years if their current growth continues.
