Interest is fixed, calculated on a daily basis and paid annually on 31 July.
Can Marsden Building Society change the interest rate?
The interest rate is fixed which means that we will not change the interest rate payable on your account prior to maturity on 31 July 2026.
What would the estimated balance be after 12 months based on a £5,000 deposit?
If you saved £5,000, the estimated balance after 12 months would be £5,207.50.
This example assumes an investment of £5,000 is made on 01 August, no withdrawals or further deposits are made throughout the 12 months, the interest earned is added to the account annually, and no changes are made to the current interest rate. It is provided for illustrative purposes only and does not take into account your individual circumstances.
How do I open and manage my account?
This account is available to UK residents and can be opened and operated online only. You may be able to open an account if you are not a UK resident. Please see the 'Eligibility' section on the product terms and conditions available on the 'Conditions' tab.
The minimum balance to open the account is £5,000. The overall maximum holding by any one person in respect of all savings accounts with the Society is £250,000. This includes money held in a joint account.
The first payment into the account can be made by debit card (up to £1,000) or by electronic payment (but not direct debit or standing order). Transfers from Marsden accounts are not permitted.
If opened by debit card, the remainder of the minimum opening balance must be paid by Faster Payment within 48 hours of the account opening.
Additional deposits can be made within 14 days of the account opening up to the annual ISA subscription limit, currently £20,000 for the 2025/26 tax year.
Transfers of used ISA allowances will be accepted on account opening where funds are accessible within 14 days and received within 30 days of account opening. After this date, no transfers of used ISA allowances will be permitted. Please note, we do not accept transfers from Stocks and Shares ISAs, Innovative Finance ISAs or Lifetime ISAs. We only accept Cash ISA to Cash ISA transfers.
Once your ISA provider has transferred your ISA to us, we will add the money to your account and backdate the interest to whichever is the soonest; either:
Can I withdraw money?
You will not be able to make any partial withdrawals before maturity.
You can close your account prior to maturity, or transfer to a new ISA provider; however you will incur an interest penalty equivalent to 150 days’ interest.
If you want to transfer your ISA to another provider, please speak to us as we will need to arrange an ISA Transfer to protect the tax-free status of your savings.
Additional information
Interest will be paid tax-free. The favourable tax treatment of ISAs may change in the future.
*Tax-free means that interest is not subject to income tax.
†AER stands for the Annual Equivalent Rate and shows you what the interest rate would be if interest was paid and added each year.
