Yes! Transferring in an ISA held elsewhere into your Cash ISA or Open Access Cash ISA does not impact your annual £20,000 allowance.
You can request a transfer of an ISA from a previous tax year (or one you have paid into this tax year) in the app under Settings > Transfer an existing ISA.
Transfers between Cash ISAs should complete within 15 working days of your initial transfer request. If you’re transferring from a Stocks & Shares ISA, this period is 30 calendar days.
You can track the progress of your transfer in the app in Wealth > Select account > Activity, and we’ll notify you by email once your transfer has been completed.
Please note that if your current ISA has not yet matured, you'll need to wait until your maturation date has passed before requesting your transfer.
