Tesco, Lidl, Asda and more price rises revealed

The analysis, from consumer champions Which?, compared how prices at leading UK supermarkets, including Asda, Tesco and Lidl, have changed over the last 12 months.

Porridge oats had risen by the most, with a 35.5 per cent increase across the eight supermarkets tested.

Semi-skimmed milk saw the second highest rise with a 33.6 per cent price increase.

While cheddar cheese was next on the list with a 28.3 per cent increase.

Though at Asda, Dragon Welsh Mature Cheddar 180g rose by 80 per cent, from £1 to £1.80.

Across all eight supermarkets, Which? found that food and drink inflation rose by 17.2 per cent in March, up from 16.5 per cent the previous month.

Sue Davies, Which? head of food policy, said: “Our latest supermarket food and drink tracker paints a bleak picture for the millions of households already skipping meals of how inflation is impacting prices on supermarket shelves, with the poorest once again feeling the brunt of the cost of living crisis.

“While the whole food chain affects prices, supermarkets have the power to do more to support people who are struggling, including ensuring everyone has easy access to basic, affordable food ranges at a store near them, particularly in areas where people are most in need.

“Supermarkets must also provide transparent pricing so people can easily work out which products offer the best value.”

An Asda spokesperson told Which?: “We’re working hard to keep prices in check for customers despite global inflationary pressures and we remain the lowest-priced major supermarket – a position recognised by Which? in their regular monthly basket comparison which has named Asda as the cheapest supermarket for a big shop every month for the last three years.

“We recently announced we would be freezing the prices of over 500 popular branded and own label products, more than half of which are fresh meat, dairy, fruit and vegetable products until the end of May.”
