Cash ISA - Withdrawal Timeframes
Withdrawals from Cash ISA are not instant. They will take 1 business day to be completed.
When requesting an interest withdrawal before 15:00 UK time on business days, it will be completed by the end of the same day.
When requested after 15:00 UK time on business days or during weekends, it will be completed by the end of the next business day.
The money is going to your Primary Pocket, where you can make a withdrawal to your bank.
Cash ISA - Withdrawal Limitations
As of October 13, 2025, there are no withdrawal limitations on the Cash ISA, and you can make withdrawals as often as you want.
As of March 31, 2026, the Plum Cash ISA is flexible. This means if you withdraw funds from the Plum Cash ISA, that specific amount is added back to your Replaceable Allowance, and you can redeposit it back to your Plum Cash ISA specifically, without impacting your allowance.
Annual Reset: Every April 6th, your allowance resets to £20,000. Any "Replaceable Amount" from the previous year that wasn't paid back is lost.
