Thanks CiaranT, so I can just transfer money back out from the NUK reg saving acc into my PTSB current account?
Yes.
With regards to KBC, I went into them a couple months ago, and they said that in order to get my money out of the reg saving account that I would need to set up a current account with them.
Not correct. You were misinformed. To do an electronic withdrawal you need a KBC current account. However, you can do a manual in branch withdrawal without having a current account with KBC.
