Revealed: The supermarkets that have hiked prices most

Cheaper items hit hardest by rampant food price inflation, major survey finds

Many everyday groceries have more than doubled in price over the last year as the cost of own-brand items continues to rise, according to consumer group, Which?

Budget and own-brand ranges have seen higher rates of inflation than premium and branded counterparts overall, according to its analysis of more than 25,000 food and drink products at eight major supermarkets: Aldi, Asda, Lidl, Morrisons, Ocado, Sainsbury’s, Tesco and Waitrose.

Staples such as milk, meat and fruit have also seen the biggest price hikes, it found.

Which? looked at the average price of the products in the three months to the end of February compared to the same time last year. Prices increased most at Lidl, followed by Aldi, Asda, Morrisons, Waitrose, Sainsbury’s, Tesco and then Ocado.

Annual inflation of popular food and drink was found to be at 16.5 per cent across the eight stores. In particular, inflation on vegetables, juice drinks, smoothies and cereal rose.

It said the price for Asda’s Free From Special Flakes (300g) increased by 129 per cent, rising from 62p to £1.43, while Waitrose’s Essential Italian Mozzarella Strength 1 (drained 150g) rose from 80p to £1.77, a 121 per cent increase.

Morrison’s Free From Corn Flakes (300g) also rose significantly from 60p to £1.29 (115 per cent).

Sainsbury’s Hubbard’s Foodstore Water (2L), Tesco Creamfields French Brie (200g) and Lidl’s Chene D’argent Camembert (250g) also more than doubled in price.

Sue Davies, Which? head of food policy, said: “Worryingly our tracker shows that some everyday essentials have more than doubled in price over the last year – with cheaper own-brand items particularly hard hit.

“Supermarkets need to step up and ensure everyone has easy access to basic, affordable food ranges at a store near them, particularly in areas where people are most in need.

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

A Lidl spokesperson said: “We are extremely concerned that since the launch of this ‘tracker’ Which? has consistently chosen to publish information that we, and other retailers, have confirmed to be incorrect. This includes data for products that we do not even sell.” Which? said Lidl has “failed to say what the inaccuracies are”.

An Asda spokesperson said: "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.”

A Morrison’s spokesperson said: “This is an unprecedented period of inflation and we are working hard to keep prices down and competitive for our customers while maintaining high standards and availability in all our stores.

“We recently reduced the price of 1,000 popular products and remain committed to doing all we can to help when it comes to the cost of grocery shopping.”

An Ocado spokesperson said: “We continue to support our customers by investing in price across branded and own-brand products. We've also recently introduced the Ocado Price Promise so customers can be sure they're getting great value.”

A Waitrose spokesperson said: “Although no retailer is immune to inflation, particularly with dairy products comprising the majority of this basket, we've been working hard to keep prices as affordable as possible for our customers – and have already committed a record £100m to lower the prices on hundreds of everyday staples.”

Aldi declined to comment.

Sainsbury’s and Tesco were contacted for comment.
