A £100 food shop six years ago now costs just under £140 as heatwaves and energy taxes pile pressure on future food prices, manufacturers have warned.

And the Food and Drink Federation (FDF) has said that extreme weather conditions and the war in Iran will continue to threaten food supplies while producers grapple with increased taxes and regulatory costs.

They estimate that the cost of the same grocery shop will increase another £8.90 or 6.4 per cent to £147.50 by July next year, driving up inflation.

The cost of a £100 grocery shop in January 2020 has risen by 38.6 per cent to £138.60, according to official figures.

This underscores the pressures faced by food manufacturers in the wake of Russia’s invasion of Ukraine in February 2022 and further conflict threatens to push up prices.
