The price of your supermarket shop has gone up at the fastest rate for four years over the past three months. If this trend continues, your family grocery shop could cost you an extra £144 over the course of a year.
Inflation, now at 3.4%, is behind the increase, according to the research by Kantar Worldpanel. It also found that,as a result, supermarket sales have increased in value by 3.2% year on year in the run-up to Christmas.
The prices of butter, fish and cola are rising fastest, but it’s good news if you’re a fan of crisps and fresh poultry, as these prices are among the few to be going down.
Prices have been rising since January 2017. To help keep the cost of your weekly shop down, we reveal which supermarket is cheapest each month.
Food and drink prices have also risen since the Brexit vote, our supermarket pricing research found. Some brands of cereal, coffee, tea and mayonnaise have seen big Brexit price hikes.

Lidl is the fastest-growing supermarket in the UK. Around 10.6 million households shopped at the discounter in the past three months and it overtook Waitrose in August to become the fifth-largest grocer in the country.
Meanwhile, Tesco is the largest supermarket in Britain, and three quarters (76%) of the population shopped there in the same period, according to Kantar Wordpanel’s research.
But is the biggest supermarket also the best? To find out, we asked more than 7,000 shoppers which supermarket they shop at and to rate it based on its range of products, stock, quality and appearance. Find out the best and worst supermarkets, according to their customers.
