Essentials such as cheese and bread have seen the biggest price increases over the past few weeks.

The cost of living crisis has hit us all hard, with inflation rising and families struggling to get by.

And now a new survey has revealed the true extent of how much our weekly shop has gone up by, with some customers paying up to 80 per cent more for items.

In a new survey by Which?, experts looked at the rate of inflation by each supermarket throughout March.

Which? analysed 26,000 food and drink products in the three months to the end of March 2023, compared to the same time period last year.

Supermarket own-label budget items were up 24.8% in March compared with the same time last year, while standard supermarket own brands increased by 20.5%.

Branded goods and premium own brand ranges were both up 13.8%, while overall food and drink inflation rose to 17.2%, compared to 16.5% in February.

Sue Davies, Which? head of food policy, said: “Our latest supermarket food and drink tracker paints a bleak picture for the millions of households already skipping meals of how inflation is impacting prices on supermarket shelves, with the poorest once again feeling the brunt of the cost of living."

What the supermarkets have said

Following the results of the survey, 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.

A Sainsbury's spokesperson said: “With costs going up, we are working hard to keep prices low. In the last two years, we have invested over £550m into lowering prices as part of our goal to put food back at the heart of Sainsbury’s."

Meanwhile, an Ocado spokesperson added: “At Ocado, everything we do starts with our customers and we know how important value is to them right now."
