global forces like the pandemic and the risk of war in ukraine have driven up fuel costs, coming home to leah's kitchen shelves. my son only eats a particular brand ofjam because he's got additional needs, and the price of the jam has gone up by a0 pence a jar. just down the road in wythenshawe is the factory where the jam's made. through that wall there is the warehouse. we've arranged a visit for leah to find out why manufacturers are boosting their prices. richard, i'mjust wondering, why are the prices ofjam going up as much as they are at the minute? it's down to a number of things. it's shipment costs, so that's getting the raw materials from around the world to the uk. that's a massive part of it. it's the cost of those raw materials. it's also the packaging materials, which is largely driven by energy costs. we've seen our costs increase by around £8 million over a 12—month period. we can't absorb those costs. the cost of gas, for example, is up 28%. liquid fuels like propane are up 47%.
