For when you want to be able to make withdrawals, but don’t need instant access
This may be right for you if:
- You’re looking for a guaranteed interest rate
- You want the tax-free benefits of an ISA
- You can leave your savings untouched for a fixed term
- You haven’t used all of this year’s tax-free ISA allowance
- You have an ISA elsewhere that you’d like to transfer
Consider something else if:
- You might want to make withdrawals but don’t want to pay a withdrawal fee
- You want an account with an unlimited term rather than a fixed period
- You’ve used the current year’s ISA allowance, and aren’t Transferring an ISA

Important information and documents
Summary Box
This Summary Box information sheet sets out the key information you need to know about your Fixed Rate e-Cash ISA. This forms part of our agreement with you, together with the General Terms and Conditions and the Fixed Rate Terms and Conditions. Please keep it for future reference.
What is the interest rate?
4.24% gross p.a.* / 4.24% AER
Interest is calculated daily and paid at maturity. You will start earning interest once your account balance reaches £1,000. If additional money is added after this point, interest will be paid on that amount from the day it is deposited.
Accounts with interest paying at maturity will have their interest paid into your Castle Trust Bank savings account on the day of maturity. Interest will be applied, but not available to be withdrawn, on each interim anniversary of the account opening for terms of more than one year and may need to be noted on annual income tax returns where appropriate.
*The Annual Equivalent Rate (AER) illustrates what the interest rate would be if interest was paid and compounded once each year, and it makes it easier for you to compare savings accounts.
Gross p.a. is the interest rate without tax deducted.
Can Castle Trust Bank change the interest rate?
Castle Trust Bank will not change the interest rate for the duration of the term of your Fixed Rate e-Cash ISA
What would the estimated balance be on the date the Fixed Rate e-Cash ISA matures based on a £1,000 deposit?
On a deposit of £1,000.00 the estimated balance would be:
| Term | Interest paid | Initial deposit | Estimated balance | Total interest payable |
|---|---|---|---|---|
| 5 year | At Maturity | £1,000 | £1,230.76 | £230.76 |
The estimated balances are for illustration only and are based on:
- interest calculated daily and paid at maturity,
- the date on which the Fixed Rate e-Cash ISA matures,
- the assumption that the Fixed Rate e-Cash ISA is not closed before the end of the fixed term.
How do I open and manage my account?
To apply for a Fixed Rate e-Cash ISA you must:
- be aged 18 or older,
- be a UK resident,
- have a National Insurance number,
- have a UK mobile number and a valid email address,
- have a UK based current account in the name of the account holder.
You can apply for a Fixed Rate e-Cash ISA online through the website and, once you have registered your online log in details, through the Self Service Portal or the mobile app. A Fixed Rate e-Cash ISA can have one account holder. You can save up to £20,000 based on the 2025/26 tax year allowance.
ISA Transfers are acceptable, subject to this funding method being available at the time of application. Please check our website for current availability.
When you open your account, you will have a 14 day funding window to make your deposit(s) to meet the minimum value of £1,000 up to the maximum value of £500,000, after this time you will not be able to make any further deposits. If we have not received a deposit within the 14 day funding window, your account will be closed.
A Fixed Rate e-Cash ISA is an online account and is intended to be managed online through the Self Service Portal or the mobile app. You can view your accounts, download copies of statements, provide your maturity instructions online as well as contact us for any queries you may have, through the message centre in the Self Service Portal.
Can I withdraw money?
This account has a fixed term, so you can only withdraw your money without incurring any charges at the end of the fixed term (also known as ‘maturity’).
You are permitted to withdraw the full amount (including transferring to another ISA provider) but this is subject to a loss of interest (known as the early exit charge). The early exit charges are dependent on the fixed rate term, they are: 1 year = 90 days’ interest, 18 months = 90 days’ interest, 2 year = 180 days’ interest, 3 year = 270 days’ interest, 5 years = 360 days’ interest. When the early exit charge is applied, it may result in receiving less money than you originally deposited. To request a withdrawal, please call us on 0808 164 5000 Monday to Friday, 9am to 5pm or send a Secure Message using the Self Service Portal.
The maturity date is determined by the fixed term selected and the date you opened your account.
Additional information
You have the right to cancel your account during the 14 days from your account opening date, we call this the “Cooling Off Period”. You don’t need to give us a reason and we won’t charge you a cancellation fee, however, if you cancel your account during the Cooling Off Period, you won’t receive any interest on your deposit for the time it was in your Fixed Rate e-Cash ISA.
We will contact you before your maturity date to explain the options available to you so you can tell us what you want us to do with your money. If your Fixed Rate e-Cash ISA matures and we have not received an instruction from you, a Maturity Holding ISA will be opened for you.
Interest is paid at the Gross Rate (tax free).
Should you need to make a complaint, you can do so by contacting us by phone, post, or by sending us a Secure Message through our Self Service Portal. Our Complaints procedure can be found on the Savings Documents page.
