Shoppers using fee-charging ATMs in c-stores will be told exactly how much they are being charged under new rules that have come into force.

Machines will now have to display the charge on screen in an easy-read size. It follows a report from the Treasury Select Committee, which slammed the operators of cash machines that charge for a withdrawal for not being straight and fair with consumers. There are 54,000 cash machines in the UK, and four in 10 charge a fee. Many of them are in convenience stores.

Dave Chew, who runs Dave’s Convenience Store in Cheshunt, Hertfordshire, has already put new signage up warning of a charge. He said: “The machine has always highlighted to users that they will be charged £1.50. They have to press a button to say they accept this before getting their money. No-one has mentioned the new sign and I don’t expect it to make any difference.”
