You can report the card as lost or stolen from the Buttle UK Application Portal and ask to have a replacement card delivered:
Click on the relevant grant record and press the ‘REPORT CARD LOST/STOLEN’ button at the top of the pop-up window.
Please do this as soon as possible. Once the card has been reported as lost/stolen the grant balance will be removed from the card. The remaining grant balance will be reloaded onto the replacement card after you have activated it.
