Every Stocks and Shares ISA or Impact Investment Account has a linked Cash Account. Cash Accounts are used for:

• holding the cash that you will use to make new investments, including regular monthly investments
• receiving dividend payments
• receiving proceeds from selling shares
• holding cash to cover your Annual Service Charge (which is charged quarterly)

You may have more than one Cash Account as a separate Cash Account is needed for each investment account you have. For example, you may have one Stocks and Shares ISA Cash Account, a sole Impact Investment Cash Account and a joint Impact Investment Cash Account.

You will see your Cash Account coupled next to the Stocks and Shares ISA or Impact Investment Account it is linked to, in your account ‘Overview’ in the Triodos Mobile Banking App or Internet Banking.

If you are adding money to your Cash Account for the first time, then this will need to be transferred from your nominated account. Subsequent payments into your Cash Account (ready to purchase more shares or to cover your Annual Service Charge) can come from any of your accounts. Take care to select the correct Cash Account to transfer money into as you may have more than one Cash Account as described above. You can find your Cash Account bank account number within the Mobile App or Internet Banking, use this along with our sort code 16-58-10.

Once you add money into a Stocks and Shares ISA Cash Account linked to a Triodos Stocks and Shares ISA, this will count as an ISA subscription for the current tax year.

Money held in your Cash Account can be transferred out to your nominated account, though you may want to keep some money in your Cash Account to cover the Annual Service charge (charged quarterly), to cover regular monthly investments or to have a balance available to purchase more shares on an ad hoc basis. If you do not keep enough money in your Cash Account to cover your Annual Service Charge, we will instruct to sell shares in your investments to cover the required amount. See What are the charges for investing? for more details on the Annual Service Charge.

You may wish to set up a standing order to make regular payments into your Cash Account, to ensure money is available for your quarterly Annual Service Charge and/or for any regular monthly investments you set up. For more information see How do I add money to my Cash Account?

If you set up a standing order into your account, please ensure the money will be received and cleared in your Cash Account before your monthly investment date, bearing in mind that standing orders will not be processed on a weekend or a bank holiday.

Yes. You can transfer an existing cash ISA to your Triodos cash ISA. If you don't already have a Triodos cash ISA, you will need to open one first. Explore our range of ethical ISAs to find the right one for you, then apply via the Triodos Mobile Banking App.

To request the transfer, you’ll need to download and complete the relevant form below. The forms are interactive so you can fill out your details online, but you’ll need to print the form and sign it using a pen.

Then simply return it to ‘Freepost TRIODOS BANK’ and we’ll transfer your money directly between your ISAs and protect your tax-free ISA status. Do not move your money out of an ISA yourself, because your money will lose this ISA status.

The transfer process usually takes between 14-30 days. We’ll write to you when the transfer is complete.

If you are transferring to a new Fixed Rate ISA, please note that it can take up to 30 days to complete a transfer. We must receive your money from your existing provider within 60 days of the Fixed Rate ISA account opening date, so please make sure you start the transfer process as soon as possible.

Yes, you can transfer other cash ISAs into a Triodos Fixed Rate Cash ISA. You can transfer previous and current years subscriptions held in another cash ISA. Transfers must be complete and your money received into your Triodos Fixed Rate Cash ISA within 60 days from account opening.

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.
