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 2023/2024 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
    • You must show us that you live, work or study in Bath to open this account. If not, you must have been a mortgage or savings customer for at least the last 12 months.
    • This account allows for Additional Permitted Subscriptions (APS). This means that if a customer with an ISA dies, their spouse or civil partner can apply to use their allowance. You can find out more by talking to our Customer Support Department.
