Her Majesty's Revenue and Customs (HMRC) ISA rules require you to make a declaration, when applying to open an ISA. This is to confirm that you are eligible to subscribe to your ISA.

If you haven't subscribed to your ISA for a whole tax year, then you need to declare your eligibility again and confirm that you haven't paid into another ISA of the same type in the current tax year. You will not be able to make any further deposits into your ISA until a new declaration is made.

You can make your declaration in Internet Banking. Go to 'Old Internet Banking', then 'Account Management' in the menu on the left, then ‘ISA Declaration Management’. Here you will be able to see the status of your ISA and if you need to declare your ISA the status will show as ‘Not declared’ -  you can click on ‘Declare now’ to do this.

We will send a notification within the Triodos Mobile Banking App (in your ‘Feed’) and Internet Banking (in ‘Messages’) if you need to make a new ISA declaration.

If you have a cash ISA and don't have online access to your account, you'll need to complete and return an ISA declaration form to FREEPOST Triodos Bank. Download your Cash ISA declaration form.

Junior ISAs and Fixed Rate Cash ISAs do not need a new declaration to be made after the account is opened.

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 If you choose to re-add money that you’ve withdrawn from an ISA, you’ll use up a portion of an ISA allowance, unless you have a flexible ISA.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?

Each child can have one Junior cash ISA and one Junior stocks and shares ISA at any one time. These can be with different providers.

A child cannot hold both a Junior ISA and a Child Trust Fund, with the same or different providers.

Moving money between ISA cash accounts by bank transfer will impact your ISA allowance. By bank transfer, we mean making a payment using the account number and sort code.

For example, if you paid money from a Cash ISA account into a Stocks and Shares ISA cash account yourself, the money leaving the Cash ISA would lose its ISA status. The money would then use a portion of your ISA allowance when it’s paid into the Stocks and Shares ISA. 

When you withdraw money from an ISA in this way, you can’t reinstate it and would 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.

If you want to move money between your Cash ISA and Stocks and Shares ISA without it affecting your ISA allowance, you will need to arrange an ISA transfer by completing an ISA transfer form (see below).

Yes you are able to transfer your Triodos Fixed Rate Cash ISA to another provider and can do this by completing a transfer request form with the other provider. Transferring a Triodos Fixed Rate Cash ISA to another provider can only be done in whole, not in part. Transferring the account before the fixed term ends will incur a charge equivalent to:

2 year term – 180 days interest

3 year term – 270 days interest

The charge will be taken from the account balance, so you may get back less than originally deposited.

There is no charge to move an account from another provider to Triodos, but you should check with your current provider whether there are exit fees or loss of benefits by transferring. 

You should also read the Important Documents for the Triodos accounts you wish to transfer to, to learn about any associated costs or fees. You can find these on the relevant product pages on our website via the links below:

• Triodos Impact Investment account
• Triodos Ethical ISAs

We are not currently opening new Junior Cash ISAs, however you can transfer funds from your Right Start Saver into an existing Junior Cash ISA, subject to the Junior ISA allowance of £9,000 for the 2023/24 tax year.

Yes you can. As long as your deposits are received within the 60 days allowed, if you open your account close to the tax year end you may be able to subscribe into your Fixed Rate Cash ISA for two consecutive tax years. You will need to check the date your last deposit is allowed, this will be detailed on your account opening letter.

Normally instructions given in internet banking to make a payment from your Triodos Cash ISA, Triodos Saver or Charity Saver account will only be carried out after the expiry of the notice period on your account. Any attempt to schedule a payment before then will be rejected.

If for any reason you need to withdraw your money earlier than the notice period, you will need to write to us by post or secure message in internet banking.

We will charge you the interest due on the amount withdrawn for the part of your notice period for which you have not given notice. So if you withdraw £500 on 15 Calendar Days’ notice from an Account set up on 33 Calendar Days’ notice, then a charge equivalent to the interest you would have earned on that £500 for 18 Calendar Days (i.e. 33 - 15) will be deducted from your Account.

For Fixed Rate ISAs withdrawals are not allowed until maturity. The only exception to this is if you close the account and/or transfer the full balance to another ISA.  Early closure will result in an early access charge being applied equivalent to a number of days of interest.

2 year term – 180 days’ interest

3 year term – 270 days’ interest

The charge will be taken from the account balance, so you may get back less than originally deposited. In exceptional circumstances the early access charge can be waived at our discretion.

Before the child turns 18 we will contact you to confirm that the Triodos Ethical Junior Cash ISA will become a variable rate cash ISA on the child’s 18th birthday. After this date the child can decide what they wish to do with the account/funds.

Yes. We will write to you one month before your fixed rate cash ISA matures, asking you to let us know what you'd like to do with your funds. You can then ask us to change your fixed rate cash ISA into another Triodos cash ISA, when it matures.

Alternatively, during the fixed term of your Triodos Fixed Rate Cash ISA, you can request to change your Fixed Rate Cash ISA into another Triodos cash ISA, but you will incur a 'breakage charge' as per the terms and conditions. The ‘breakage charge’ is equivalent to:

• 2 year term – 180 days' interest
• 3 year term – 270 days' interest

The charge will be taken from the account balance, so the balance in your new type of Triodos cash ISA might be less than originally deposited in your Fixed Rate Cash ISA.

There is no charge when changing to a different type of Triodos cash ISA on maturity.

For more details, see our how-to guide below on changing your cash ISA to a different type of Triodos cash isa.

Yes. As long as the child was a UK resident when the Junior cash ISA was opened, you will still be able to pay into the Junior cash ISA even though you and/or the child have moved abroad.
