Tesco has put the price of its lunchtime meal deal up from £3.60 to £3.85 for Clubcard holders.
Customers who do not have a loyalty card will see the price rise from £4 to £4.25.
Shoppers picking up a main, snack and a drink will be charged at the new rate from Thursday.
It is the latest example of the continuing rise in food prices in the UK. Tesco said its meal deal “remains great value”.
It’s understood some of the most expensive items in the standard meal deal would cost more than £8 if purchased separately.
Tesco also offers a premium meal deal which has gone up from £5 to £5.50 for those with a Clubcard and £6 for those without.
The sandwich, snack and drink deal had cost £3 for 10 years before prices were hiked in October 2022 when food prices were rising at their fastest rate in 42 years.
The rising cost of food has been persistent, with the latest inflation figures showing food and non-alcoholic drink prices rose 4.9% in the year to July.
But a look at the trend over in five years to July, food prices increased by around 37%. That compares with a rise of 4.4% over the previous five-year period.
Tesco is among dozens of retailers who have written to Chancellor Rachel Reeves to warn that any new taxes on businesses she could announce in the Autumn Budget would push up prices further for customers.
The letter send by the British Retail Consortium said: “As retailers, we have done everything we can to shield our customers from the worst inflationary pressures but as they persist, it is becoming more and more challenging for us to absorb the cost pressures we face.”
It said changes the government has already made to employer National Insurance, higher employment costs and the introduction of a new packaging tax had added £7 billion in new costs to retail businesses.
The Bank of England has said these cost increases may have added 1% to 2% to food prices. It expects food price inflation to peak at around 5.5% at the end of the year, before falling to between 2% and 3% in 2026.
