Flexible Cash and Stocks & Shares ISA with the same provider

Hello If you've opened a Cash ISA in Bank A in previous tax years, and in this tax year paid £5000 into the account. And you've opened a Flexible Stocks & Shares ISA with Bank B, and paid £15,000 into the account, Now you've opened a Flexible Cash ISA with Bank B, and want to move money between the 2 flexible ISA accounts in Bank B as required (without depositing any outside funds into either ISA accounts). Would this be compatible with the current regulations as the 2 ISAs are flexible? Many thanks in advance for your help.

Hi
Yes. You will need to get the provider to arrange the transfer.
