Tesco, Asda, Sainsbury's, Morrisons shoppers who buy chocolate or tea 'warned'

Supermarket shoppers at Tesco, Morrisons, Asda and Sainsbury's have been warned over rising grocery bills.

Tesco, Sainsbury's, Morrisons and Asda shoppers have been warned over food inflation - as one popular item sparks skyrocketing prices. Supermarket shoppers at Tesco, Morrisons, Asda and Sainsbury's have been warned over rising grocery bills.

Pete Mugleston, money expert and MD of www.onlinemoneyadvisor.co.uk, said: "The cost of the average supermarket shop may increase by more than the reported inflation rate. This is because some items can experience sharper price increases, and consumers may implement selective pricing strategies.

"There is a real concern that food costs could continue to drive up the overall cost of living, especially with winter heating bills on the rise. The combination of increasing food prices and higher energy costs could create financial strain for many households."

Chocolate has risen 9 per cent - in a brutal blow to shoppers. Rajan Lakhani, personal finance expert at smart money app Plum, said: "Prices for some items are continuing to be very high, for example olive oil, coffee and cocoa, which have all suffered due to extreme weather in the regions where they are produced.

"Global geopolitical events also continue to make their presence felt in our supermarket trollies even with inflation getting under control." Rajan said: "The autumn heading into winter is always an expensive time for food shopping due to the Christmas period, plus finances are under extra pressure from present shopping and higher energy bills over the winter period."

Greg Marsh, CEO of money-saving tool Nous.co, commented: "Rising food prices hit lower-income households hardest, because they spend a bigger proportion of their wages on groceries. At the same time, energy bills have risen just as we move into the colder months, putting extra pressure on stretched budgets."

Other items skyrocketing in price include teabags, according to the latest inflation figures in the UK released this week.
