Once you have opened your Triodos Fixed Rate Cash ISA, you have 60 days in which to deposit as much of your ISA allowance as you want to. If you do not deposit your full allowance in your Fixed Rate Cash ISA you can invest the remainder in any combination of the rest of the permitted ISA types with Triodos or other providers.
Thanks for your feedback. We’ll use it to improve our services.
The ISA allowance is the maximum amount you can invest across all types of ISAs in any one tax year. You can put your whole allowance into a particular type of ISA or you can split it between the different types of ISAs: Cash, Stocks & Shares, Lifetime and Innovative Finance. The ISA allowance for the 2025/26 tax year is £20,000. For Junior Cash ISAs, the allowance is £9,000.

The notice period has been removed from Triodos Cash ISA, Triodos Saver and Triodos Charity Saver. As a result these are now instant access accounts and no early access penalties will be applied.
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.

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.

The Financial Services Compensation Scheme (FSCS) is a UK body which gives you automatic protection up to £85,000 if your bank, building society, or credit union goes out of business.
Your eligible deposits with Triodos Bank UK are protected up to a total of £85,000 by the FSCS. An eligible deposit is money in accounts such as current and savings accounts, including cash ISAs. With Triodos, this will also cover cash held in investment accounts but not the investments themselves.
Please note that the £85,000 will apply to the total of all eligible deposits with Triodos Bank rather than per account or product. Any deposits over this amount are unlikely to be covered.
For more information, please visit the Triodos FSCS webpage.
