Please read the Key Product Information below before applying

  • What is the interest rate?
    • £1+ 3.94% AER*.
    • We calculate the interest daily and pay it annually on 31st December. Interest can be added to your account or paid to your nominated account.
    • *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 variable, so it can go up or down at any time.
    • For more details about why we might change the rate, you should read your Welcome to your Bath Building Society Account brochure.
  • What would the estimated balance be after 12 months based on a £1,000 deposit?


    • 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 or paid in.
    • ISA means Individual Savings Account. When you pay money into your ISA, you subscribe to your ISA. Your payments are called subscriptions. As it is tax free, you get to keep all your interest.
    • 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 live in the UK 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 2024/2025 is £20,000.
    • Your subscriptions can be split between Cash ISAs and Stocks and Shares ISAs up to the overall ISA allowance. We do not offer Stocks and Shares ISAs.
    • You cannot transfer your Cash ISA into this account.
    • You can open an account on this product page or by visiting one of our Branches in Bath.
    • You can manage the accounts you hold with us through Bath Online, or by using our Mobile App. You can register for Bath Online on our website, and you can register for the Mobile App on your smartphone.
    • Account holder identification will be required. This is usually obtained through our electronic identity verification service. However, if this proves inconclusive, here’s some popular ways to verify your ID.
  • Can I withdraw money?
    • This is an instant access account. 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 one of our Branches in Bath. There is no limit to how much you can withdraw
    • You can also ask us to make a faster payment to your nominated account. This can be done on Bath Online, through the Mobile App, or in a Branch. You can also send us a signed letter in the post, or an email from your nominated email address.
    • 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.
    • You can transfer previous tax year subscriptions to another ISA provider. After you speak to your new ISA provider, they will let us know so we can make the transfer.
  • Additional information

Here are some Frequently Asked Questions about ISAs

  • What is an ISA?

    An Individual Savings Account (ISA) allows you to save or invest money without paying tax on the interest earned.

  • Are ISAs tax free?

    With an Individual Savings Account (ISA) you don’t pay tax on the interest you earn. You can only currently open a Cash ISA or Lifetime ISA with Bath Building Society but there are also Stocks & Shares ISAs available from other providers.

  • How much can I save tax free in an ISA during the tax year?

    Every year, starting on 6th April, you will receive a new ISA allowance. The ISA allowance for 2024/25 is £20,000. You can split your allowance across the different types of ISA and can pay into multiple accounts of each type, but you may only subscribe to one Lifetime ISA in any tax year. Please note Bath Building Society only offers Cash ISAs and Lifetime ISAs.

  • How do I apply for an ISA?

    If you are eligible to apply for a Bath Building Society Cash ISA you can apply via this product page or on our Mobile App. You can also open an account at one of our Branches.

  • Can I open an ISA in joint names?

    No. As the tax free savings accounts relate to personal tax allowances, you cannot hold an ISA jointly with anyone else.

  • Can I cancel my tax free savings from another provider to Bath Building Society?

    We currently do not accept transfers of an existing ISA, Junior ISA or Lifetime ISA to Bath Building Society. This status is regularly reviewed.

  • Can I withdraw money from a tax free savings account?

    You may be able to withdraw money from your ISA depending on the terms & conditions of the account you have with us. Any money withdrawn will lose its ISA status unless it is transferred out to another Bath Building Society ISA or another provider.

  • What is an APS ISA allowance?

    APS stands for Additional Permitted Subscription. An APS ISA allowance is an additional allowance which is granted to the surviving partner on the death of a spouse or civil partner.
