Aisle be damned – Which? reveals which of Britain’s favourite branded foods have gone up the most

Some of the nation’s most popular branded foods have soared in the last two years with the worst examples doubling in price, according to new Which? research which looks at how much supermarket prices have shot up.

In a new investigation, the consumer champion found popular branded products such as Heinz Ketchup, Dolmio sauce and Anchor butter have soared in the last two years – with some price hikes over 100 per cent.

Which? looked at 79 branded items, comparing prices at six major supermarkets, Asda, Morrisons, Ocado, Sainsbury’s, Tesco and Waitrose, over a 30 day period from 21 September to 20 October in both 2020 and 2022.

Out of the items on Which?’s shopping list, Heinz Tomato Ketchup – top down (460g) saw the biggest average percentage increase overall, going up by 53 per cent or 91p across the six retailers – although this was as much as 70 per cent or an increase of £1.06 in one particular supermarket over the two-year period.

The second biggest average percentage increase on the branded products included in Which?’s list was on Dolmio Lasagne Sauce (470g) which went up by 47 per cent or 61p across the six supermarkets in the two years. However the price increased by as much as 107 per cent or £1.09 in one supermarket.

Heinz Classic Cream Of Chicken Soup 400g also went up an average of 46 per cent or 44p across the board from around £1 to almost £1.50.

Even foods such as student staple, Batchelors Super Noodles Bbq Beef Flavour (90g) went up an average of 43 per cent across the six supermarkets, according to Which?’s analysis, from an average 59p to 82p.

Prices also increased on basics such as Hovis Granary Wholemeal 800g, increasing by an average of 43 per cent or 58p across the six supermarkets, from £1.39 to £1.97 on average.

One of the biggest leaps in terms of pounds and pence was on branded butter. Anchor Spreadable butter tub 500g went up by £1.31 (45%) on average across all six supermarkets over the two-year period. Meanwhile Lurpak spreadable slightly salted tub 500g saw an average increase of £1.17 (35%).

The price of Twinings of London Everyday 100 Tea Bags had the sharpest individual increase in absolute terms at one supermarket – an extra £2.33 (64%) in 2022 compared to the base price in 2020. Across the six retailers the teabags went up on average 64p (17%).

Which?’s findings show that despite overall inflation being at almost 15 per cent since this time last year, some of Britain’s favourite branded foods may have risen much more sharply and prices on specific products across the supermarkets can differ significantly. 

While shoppers could save money by shopping around or avoiding branded goods, people could be paying over the odds if they live in areas not well served by a choice of larger supermarkets or retailers that do not stock cheaper own-brand and budget ranges.

Which? believes supermarkets need to do more to support all consumers through the crisis by making sure food prices are easy to understand to make budgeting much simpler, making sure budget lines are available throughout stores and online, and providing targeted promotions to support people in the areas that are struggling the most.


Sue Davies, Which? Head of Food Policy, said: 

“Our research shows the shocking rate of inflation on some of the nation’s favourite branded foods, which is much higher than the national average and highlights why it is so important for retailers to provide people with a choice of product ranges.

“Supermarkets must ensure budget lines for healthy and affordable essential items are widely available across their stores including smaller convenience stores. Promotions should be targeted at those most in need and people supported so they can easily compare the price of products to get the best value.”
