New data has revealed which groceries have increased in price over the last year

The price of 30 grocery items in your regular food shop have changed in price over the last year, according to newly released data.

By collecting online grocery prices from seven major supermarket websites and assessing the costs for the 30 items, the Office for National Statistics (ONS) has revealed how our grocery bills have changed compared to last year.

Just how have prices changed since April 2021?

It turns out pasta has increased by 50% in price, while the cost of potatoes has dropped by 14% since April 2021.

In terms of the largest price rises in cash terms, beef mince now costs the most as it has risen by 32p to £2.34 for 500g.

Chicken breast has increased by 28p to £3.50 for 600g, while pasta has increased by 17p and vegetable oil by 14p.

However, that’s not the case across the board.

Potatoes fell by 12p meaning it now costs 75p for a 2.5kg, while cheese dropped by 7p to 88p for 255g, and pizza decreased by 4p to an average of 95p for 300g.

These products are the anomalies though – most lowest-cost grocery items have increased at a similar rate to the official measure of inflation for food and drink, by climbing by 6%.

Here’s a breakdown of the price changes as analysed by the ONS:


ONS noted this had occurred throughout their investigation – it’s when pack sizes reduce but the product still costs the same.

The organisation is not the first to find this either. The Financial Times noted back in March that Doritos bags allegedly had five fewer chips, while Cottonelle toilet rolls lost 28 sheets while still charging consumers the same amount.

How have prices changed since March?

Even in the past four weeks of the ONS survey, it found that the lowest prices increased by 0.9%.

Over the past month alone, the items with the largest increase in the lowest price were breakfast cereal, which increased by 6%, mixed vegetables and vegetable oil (5% increase).

This is down to the increasing pressures from the Ukraine war (as its exported crops are not able to leave the country) along with the global cost of living crisis.

Is everything getting more expensive at the same time?

Prices have been fluctuating at different rates to each other.

ONS explained the exact timing of these price increases varied according to each product, with pasta surging between November and December while baked beans climbed in price between October and November.

Sugar-free or low-salt items of the lowest-cost items often cost the same as the standard version.

So, what does this mean?

As anti-poverty campaigner Jack Monroe pointed out on Twitter the new data suggests “the hikes in the value brands and basics have been much higher than average inflation stats” show.

The Institute for Financial Studies revealed last week that while most of the UK is dealing with a 9% increase in prices, British households with the lowest income are struggling with 10.9% inflation instead.

Monroe also pointed to their own research from January. They monitored the way prices in basic groceries had fluctuated recently and went viral for analysing how those everyday basics compared to the change in prices for more luxury items.

Monroe tweeted that this latest study was conducted following their campaign earlier this year. They added: “As I have said for 10 years now, and as many others have pointed out before + alongside me, it’s FAR more expensive to be poor. And now the literal experts in data gathering and statistics are helpfully, methodically, forensically backing that up. This feels like huge progress.”
