About your cash ISA


Make your deposit by electronic bank transfer, cheque, from an existing Paragon account or by transferring existing ISAs. You can make unlimited deposits, just stay within the minimum and maximum balance, and your annual ISA allowance.


You can make withdrawals with only 40 days’ notice. Early withdrawals are subject to 40 days’ interest penalty, so if you close your ISA in the first 40 days you may get back less than you invested.

With Flexible ISAs and our ISA Wallet any amount you withdraw is added back to your annual ISA allowance for you to reinvest with us.

Nominated bank account

To help keep your savings safe, your Paragon accounts must be linked to a nominated bank account. This account must be a UK current account in your name, and we will only accept money from and send your savings to your nominated bank account.

Closing your ISA

If you change your mind, you have the right to close your ISA within 14 days of us receiving your opening deposit. If closed in this way it won’t count as an ISA subscription.

You can close your ISA by withdrawing all your savings, or it will be closed if it falls below the minimum required balance.
