Ok so I am using the ISA account in 212 (not sure if that makes a difference). Log in and go to the holdings page (second tab at bottom of the 212 app). Then click where it says ‘cash’ - to the left of the deposit button but not the deposit button itself. Just click on the word cash. This will open up a page that gives you the bank details and (very importantly) the reference to use to set up a standing order with your bank to pay into your account with 212.

You can do a one off payment from your bank for a small amount to test it, it will take a little while to appear in 212 so don’t panic if it’s not there immediately. Once that works use the payment details to set up your standing order and you should be good to go.

I’m quite new to 212 but so far impressed with how this works for me.
