Heinz Tomato Ketchup – top down (460g) experienced the greatest average percentage increase across all six retailers, rising by 53% (91p).

Several of the most popular branded foods in the United Kingdom have doubled in price over the past two years, according to new research.

Whose investigation is it? We compared the prices of 79 branded items at six major supermarkets (Asda, Morrisons, Ocado, Sainsbury’s, Tesco, and Waitrose) over 30 days from September 21 to October 20 in both 2020 and 2022.

Aldi and Lidl were excluded from the study because they lacked enough comparable products.

Heinz Tomato Ketchup – squeezable top down (460g) – saw the greatest average percentage increase across the six retailers, rising by 53% (91p) compared to the other items on their shopping list.

However, in one store it had increased by as much as 70%, amounting to an increase of £1.06.

Dolmio Lasagne Sauce (470g) experienced the second largest average percentage increase among the branded products on Which list, ?’s increasing by 47% or 61p across the six supermarkets in two years.

In one grocery store, the price increased by up to 107 percent, or £1.09.

One of the greatest increases occurred with branded butter. The price of 500g tubs of Anchor Spreadable butter increased by £1.31 (45%) on average across all six supermarkets over the course of two years.

Meanwhile, the average price of Lurpak spreadable slightly salted tub 500g increased by £1.17 (35%).

Earlier this year, it was discovered that a pack of the spread costs more than £7 in some supermarkets.

In 2022, Twinings of London every day 100 Tea Bags will cost an additional £2.33 (64%), compared to the base price in 2020, at one particular supermarket. The average price of tea bags across the six retailers increased by seventeen percent or 64 pence.

In the 12 months leading up to September, the price of inexpensive everyday goods climbed by 17%, which was greater than the average rate of food and beverage inflation.

Based on web-scraped supermarket data for 30 common grocery goods, the results indicated that item prices had grown by 7% in the year leading up to April.

In the past year, sales of tea increased by 46%, chips by 39%, bread by 38%, and cookies by 33%.

Overall, grocery inflation stands at 14%, with households facing a £643 average yearly increase in expenditures.

Sue Davies, head of food policy at Which?, stated, “Our research reveals the shockingly high rate of inflation on some of the nation’s favorite branded foods, which is significantly higher than the national average, and demonstrates why it’s so crucial for retailers to offer a variety of product ranges.”

“Supermarkets must ensure that budget-friendly essentials are generally available in all of their outlets, including smaller convenience stores. Those most in need should be the focus of promotions, and people should be assisted so they can readily compare prices to find the best deal.”

According to data collected last month, millions of households skipped meals or struggled to put nutritious food on the table.

As a result of the rising cost of living, almost 85 percent of consumers in the United Kingdom are reducing their food spending, most typically by seeking out foods on sale, according to data by the consumer organization Which?

Half of the 9% who said they are finding it “extremely difficult” to make ends meet and a quarter of those who are finding the current situation pretty tough reported that their household was skipping meals.
