Summary Box

Account name

2 Year Fixed Rate ISA (31.01.2026)

What is the interest rate?

5.15% Tax-Free***/AER**

Interest is added to the account annually on 31 January or can be paid into another Suffolk Building Society account or direct to your bank account on an annual or monthly basis. Interest paid monthly cannot be added to the account.

Can the Society change the interest rate?

The interest rate is fixed until the maturity date on 31 January 2026.


What would the estimated balance be after 12 months based on a £1,000 deposit?

If you were to open this account with £1,000 and no further deposits or withdrawals were made, you would earn £51.50 interest each year. If you chose to have interest compounded, this would result in a total balance of £1,105.65. This is due to earning interest on your interest each year. Please note, this is an illustration only and does not reflect your specific circumstances.

How do I open and manage my account?

To be eligible for this account, you need to:
• Be a permanent UK resident, aged 16 or over.
• Deposit a minimum of £100 up to a maximum of £200,000.
• Save up to the maximum annual HM Revenue & Customs (HMRC) ISA limit.
• You can also transfer an ISA from another provider where you have not used any flexible withdrawal or deposit options.
• Be an existing member or a new member resident in postcode areas AL, CB, CM, CO, IP, LU, MK, NR, PE or SG.

You can open an account:
• By completing the appropriate application form.
• Visit any of our branches with your opening investment of cash or cheque or apply by post by sending the application form with an opening cheque.
• Provide proof of identity. Acceptable forms of identification are detailed in our ‘Verifying your identity’ leaflet. Alternatively, our staff will give you full details.

How to manage your account:
• Once an account is open, you can save up to the maximum annual ISA limit up to and including 5 April 2024.
• No additional subscriptions can be accepted after 5 April 2024.
• You can transfer an ISA from another provider, whilst this 2 Year Fixed Rate ISA (31.01.2026) remains available to open.
• You can only subscribe to one cash ISA with one provider in any tax year, however you can invest up to the maximum annual ISA limit across other types of ISAs.

Can I withdraw money?

You cannot make partial withdrawals.
• However, your account can be closed or transferred to another ISA provider before the maturity date subject to a penalty equivalent to 120 days’ interest. This means that you can access your funds instantly where you accept the penalty.
• The penalty will first be deducted from accrued interest. If there is insufficient accrued interest the penalty will be deducted from the balance in your account.
• If you close your account, your savings will lose their tax-free benefit unless you are transferring your funds to another ISA provider.

What happens at the end of the fixed rate term?
• Your account will mature on 31 January 2026, with funds available to you on the next working day.
• We will contact you 14 days before maturity with details about the proposed account your savings will be transferred into.
• Your savings will be transferred to another fixed term account with the closest access and duration to this ISA. We will also confirm how to transfer to an easy access account or close your account.
• You will be given full access to your funds for a specified period if you have other plans for your savings and wish to withdraw your funds or choose an alternative product.


Interest is free of Personal UK Income Tax, your Personal Savings Allowance and Capital Gains Tax.
