Which groceries have risen most in price, as food inflation remains in double-digits?

Food inflation may be falling, but shoppers will be yet to feel the difference in their pockets as prices on the whole keep rising.

London, UK. August 17, 2023. The price of food rose by 14.9% in the year to July 2023, according to the latest Consumer Prices Index.

UK food inflation has been slowing down month-on-month, but it still remains stubbornly high with shoppers yet to feel a substantial difference.

British Retail Consortium (BRC) data suggests it dropped to 11.5% in August from 13.1% in July and 17.4% in June, suggesting there is some light at the end of the tunnel.

While consumer price index (CPI) inflation sits at 6.8% - far higher than the Bank of England's 2% target, chancellor Jeremy Hunt has said Britons could expect it to fall to around 5% after a "blip" in September.

This may all sound encouraging, but falling inflation doesn't mean that prices are falling yet, it just means they aren't increasing at such a fast rate.

Furthermore, with annual growth in average total pay only reaching 8.2% from April to June, according to the Office for National Statistics (ONS), shoppers are still being hit especially hard at supermarkets.

Here, Yahoo News UK takes a look at which staple groceries are still remaining stubbornly high and which supermarkets are proving the priciest.
