I am looking to triple dip and have already initiated a switch to NatWest which should be complete in a couple days.

I am still waiting for my donor accounts to have their Direct Debits set up so I can then start the switch processes for Ulster (account is set up ready and waiting for a switch) and RBS (still need to set up an account).

If I just don't pay in the money to NatWest until the other two are set up/switched, can I then deposit the required funds into all three accounts one after another to fulfill their requirements in quick succession? Or has setting up my NatWest switch early potentially messed with my chances for an ideal triple dip scenario?
