Supermarkets are charging up to three times as much for pre-sliced vegetables, Which? research has found.

We all know that supermarkets will charge you more for sliced fruit and vegetables, but the difference between fresh and prepared is bigger than you might think.

When we looked at the cheapest prepared carrots and compared them to buying loose, we found that Sainsbury’s had the biggest price difference with pre-sliced carrots costing £2.50 per kilo compared to 75p per kilo for loose.

Other supermarkets were hardly any better. Morrisons also charged more than three times as much for pre-sliced, at £2.16 per kilo compared to 67p.

Tesco charged £1.79 per kilo for pre-sliced and 75p for loose. Asda had the smallest difference, but the pre-sliced price of £1.23 per kilo was still almost double the 67p loose price.
