THE AVERAGE annual grocery bill across Great Britain is forecast to rise by £643 this year, according to research firm Kantar.
That means shoppers could be paying on average an extra £12 a week for food and other groceries.
Back in June, the firm predicted the cost of the average annual supermarket shop would go up by £380 in 2022.
Food prices have soared this year, with the war in Ukraine helping to drive up prices at supermarket tills.
The survey also showed the price of a weekly shop rose 13.9 per cent in September, compared with the year before.
That marks another record high since Kantar first started tracking the sector in 2008.
