Can I transfer money from a savings pot to another savings pot?
No you can’t. You have to withdraw to your current account first.

This is something I’ve also been looking for.
It might seem a little lazy to ask, but is there a reason it has to be withdrawn from the pot into the main account before being deposited into the new pot?
I’m not sure about the non-interest bearing pots but for the interest bearing pots I would presume it is because pots are with different providers at different interest rates and therefore different T&Cs.
Cause them’s the rules
Any further news on new saving pots?
