Clicked on the deposit screen this afternoon and right down the bottom I noticed another option to display my account number and reference for transfers. After clicking a button to confirm it’s only to be used by my open banking account, I received the details.
Opened First Direct, account name “Chip” (didn’t know what else to use!), entered sort code, reference and amount, clicking through two warning FD signs, I started the transfer (tested £1 first)
Within seconds it was in my chip account!
Made three transfers now, latest was £600 with no problem.
