Britain’s cheapest supermarket in 2016: Asda comes top on Which? survey

Asda has been titled as the cheapest supermarket in the UK in 2016 by which?, a consumer group. The most expensive among the top UK supermarkets was Waitrose. Which? compared a basket of 80 popular items- from Dolmio sauce, Nescafe Gold Blend coffee to Warburtons bread from these supermarkets to zero the cheapest one. The Asda basket cost £154.14, whereas the Waitrose basket priced  £18 more than that at Asda.  Sainsbury’s was the next cheapest at £162.11, followed by Tesco (£164.37), Ocado (170.35) and Waitrose (£172.27).

Which? magazine editor Richard Headland said: “With increasing concern over rising food prices, our research shows that some supermarkets are consistently cheaper than others. It could be worth switching supermarkets, or shopping around, if you want to trim your shopping bill.”

To compare supermarket prices across the year, Which? compiles a list of more than 100 popular products, which were likely to be sold in the six supermarkets covered by the comparison. Using data from the independent shopping website MySupermarket, they calculate the average price (including discounts, but not multibuys) for each item across the whole of 2016. Then the average prices are added to get the cost of the basket.

Asda was consistently dominant all year, coming out on top in 11 out of 12 months in 2016. February was the only exception, when Morrisons bumped it into second place. When it came to picking up Best Buys for own-brand products, Marks & Spencer was the clear best supermarket in 2016. Overall, it won seven Best Buys.  In total, eight supermarkets won Best Buys for their own-brand products in 2016.
