HSBC has confirmed it is joining banking group Royal Bank of Scotland (RBS) in refunding people who forgot to take their cash when making an ATM withdrawal.
The bank said it will automatically refund money left behind between 2005 and 2010, although the process will not be immediate.
Notes are automatically sucked back into cash machines when customers forget to take their money.
A spokesman for HSBC said the bank changed its policy in January 2011 so that people who forget to take their money from its machines are proactively refunded.
It is working with the UK Payments Council to install a system which will give automatic refunds as far as records allow.
The HSBC spokesman could not give an estimate for how many people are affected or the total cost. Those who have lost out will be told about their refund in due course.
Banking group RBS, which includes NatWest, has started writing to thousands of its cash machine users in recent weeks to tell them that they are in line for a refund.
A spokesman for RBS said: “We have identified people over a number of years looking back who have left money in an ATM and have forgotten to collect it.”
If a person forgets to take the money at an ATM machine, the machine will take back the cash and keep it safely. The person’s account will not be credited with the amount that was just taken back by the ATM.
The person, however, is advised to contact their bank’s customer care and explain the situation. The bank will check the ATM cash balance and then refund the money, if the machine had indeed taken back the money.
