Please read the Key Product Information below before applying

  • What is the interest rate?

    £1+ 3.90% *AER

    • We calculate the interest daily and pay it to your account on maturity.

    *AER stands for Annual Equivalent Rate and shows what the interest rate would be if interest was paid and compounded once each year. The gross rate is the interest rate payable before tax.

  • Can Bath Building Society change the interest rate?
    • The interest rate is fixed, so it will not change for the length of the term.
    • For more details about when we might change one of our rates you should read our Savings Terms & Conditions.
  • What would the estimated balance be after 12 months based on a £1,000 deposit?

    £1,039.00

    • This would be the balance after 12 months if £1,000 was paid in, all interest was paid back into the account, there was no change to the interest rate and no money was taken out.
    • This is just an example to help you compare accounts. It does not take into account what you may do with the money in your account.
  • How do I open and manage my account?
    • You must be a UK resident for tax purposes to open this account or be a Crown Employee serving overseas. You can also open this account if you are in a marriage or civil partnership with a Crown Employee. You can open it with as little as £1.
    • This account can only be opened by you. You cannot have a joint account.
    • This is a Cash ISA. You can only subscribe up to the maximum ISA allowance each tax year. The overall ISA allowance for 2025/2026 is £20,000.
    • You can only have one Fixed Rate ISA with Bath Building Society.
    • Bath Building Society does not allow transfers of your Cash ISAs into this account.
    • Your subscriptions can be split between multiple Cash ISAs and multiple Stocks and Shares ISAs up to the overall ISA allowance. We do not offer Stocks and Shares ISAs.
    • However, you can only subscribe to one cash ISA with Bath Building Society each tax year, so you would not be able to pay into both a Fixed Rate ISA and Instant ISA for example.
    • You can add money to the account for 14 calendar days after the account is opened. After this period no further additions are allowed.
    • You can open an account on our website, using our Mobile App, or by visiting one of our Branches in Bath.
    • If you open your account on our website or by using our Mobile App, you will receive an opening certificate.
    • If you open an account in Branch, a passbook will be issued to confirm your opening deposit.
    • You will need a passbook if you want to withdraw or deposit money in our Branches. Passbooks are available on request.
  • Can I withdraw money?
    • You can take out money whenever you wish in a Branch, up to a maximum of £500 without telling us first. If you tell us first, you can withdraw up to £2,000 the next day.
    • You can withdraw by cheque from our Branches. There is no limit to how much you can withdraw.
    • You can also ask us to make an electronic payment to your nominated account. This can be done on Bath Online, through the Mobile App, in a Branch, or you can contact our customer service team.
    • You can only have one nominated account. You should choose the best account for your money to be paid in to.
    • We will make a charge equivalent to 90 days’ interest on all withdrawals.
    • This is not a flexible ISA. If you take money out of your account, it does not change the subscription limit. For example, if you put £2,000 in this account and take out £1,000, you can only put in another £18,000.
    • Transfers of current year and/or existing subscriptions are permitted to another ISA provider. You will need to fill out an application form with them. They will then communicate with us to arrange the transfer.
  • Additional information
    • We will let you know the balance held in the account in the welcome letter.
