If you arrange a transfer between ISAs by completing a transfer form, your tax-free ISA status will remain protected and the transfer will not affect your ISA allowance for the current tax year.

Don’t withdraw the money out of an ISA yourself or move it to a personal bank account. If you do this, your money will lose its ISA status. This means that you can’t reinstate it and you’ll permanently lose that portion of your ISA allowance. If you choose to re-add money that you’ve withdrawn from an ISA, you’ll use up a portion of an ISA allowance, unless you have a flexible ISA.

To top up a Triodos cash ISA you can:

• Make an online payment from another account (either an account with another provider or another Triodos account that allows withdrawals).
• Send us a cheque if the Triodos cash ISA you want to top up accepts cheque.

The following accounts do not accept cheque payments:

• Online Cash ISA
• Fixed Rate Cash ISAs

If you want to deposit a cheque, please post it along with your account details or a paying-in slip to: ‘Freepost TRIODOS BANK’ (no stamp required)

The Triodos Bank sort code is 16-58-10 and you can find your Triodos cash ISA account number by logging in to your account online or via the Triodos Mobile Banking App, or by checking your bank statements.

Please note, if you have not paid into your ISA since 5 April 2022 you will need to declare your eligibility before transferring your money. For more information see Do I need to declare my ISA and how do I do this in Internet Banking?

When you pay funds into your Account, your funds will start earning interest from the day the funds are paid into your Account.
