Could my switch application be rejected?
Your switch could be rejected if the personal details you gave us don't match those held by your old bank. So please make sure your old bank has your up-to-date details. If switching with Pingit, please make sure your old bank has the same personal details you use for Pingit.
Also, with a full switch, you have to visit a Barclays branch and confirm your identity within 5 working days.
If your switch is rejected for any reason, you can re-apply but should make sure it doesn't fail again.
