Asda has been revealed to be the cheapest UK supermarket for the fifth successive month with Tesco and Morrisons among the most expensive, a study suggests. The study by price tracker website alertr follows the cost of 43 items contained in the Government's Consumer Price Index 'shopping basket' on a week-by-week basis at the country's biggest online retailers. Asda was cheapest for three out of the five weeks, with Iceland taking the top spot for the last two weeks of September.
However, even with Iceland's average basket cost being GBP2.09 cheaper than last month, Asda still took the overall crown despite the average total being up 0.20p on its August pricing.
Tesco was crowned the most expensive supermarket for September, but has now been usurped by Ocado which comes in with an average basket spend of GBP151.24, GBP3.31 more than last month and a staggering GBP11.60 more than Tesco. Andy Barr, co-founder of alertr, said: "I t is interesting to see that Waitrose has unexpectedly been more affordable than some of our go-to 'cheaper' stores. "Despite Tesco continuously coming up as one of the more expensive retailers, the data from September does seem to indicate that they've begun to drop their prices as we enter another tricky phase regarding the global pandemic.
"Sainsburys is also another surprise as it comes in third cheapest retailer for the shopping list, somewhat surprising as it's notoriously known for its higher-end offerings. "At this point, it's starting to look like Asda can't be beaten on their low prices, and competitors will really have to think about introducing better deals or offers in order to keep customers loyal, particularly at a time when so many are looking to cut their spending in any way possible."
The online price tracking website has been tracking the prices of 43 everyday items from the shopping basket on the Office for National Statistics' Consumer Price Index (CPI) since 2019.
Included within the list are items such as eggs, milk and bread, as well as non-perishables like pasta, rice and cereal. The prices across seven of the largest supermarkets are analysed, with discount retailers Lidl and Aldi not included due to the inability for customers to shop full ranges online. The full breakdown of supermarkets average basket costs from lowest to highest over the five-week period in September were as follows:
1. Asda - GBP130.36 - 20p more than last month
2. Iceland - GBP132.40 - GBP2.09 less than last month
3. Sainsburys - GBP135.24 - GBP4.27 less than last month
4. Waitrose - GBP139.50 - 64p more than last month
5. Tesco - GBP139.64 - GBP9.34 more than last month
6. Morrisons - GBP141.53 - GBP4.22 less than last month
Ocado - GBP151.24 - GBP3.31 more than last month
