Interest is calculated on your daily balance and paid on maturity or monthly, paid one month after the date on which your ISA is opened, and then monthly after that, depending on what you choose.
Can Principality change the interest rate? No, the rate on this ISA is fixed for 18 months until maturity.
What would the estimated balance be after 18 months based on a £1,000 deposit? £1,025.20 (based on the assumption that you chose to have interest paid on maturity and added to your ISA and that no further deposits were made).
How do I open and manage my account?
  • You must be aged 16 or over, a UK resident for tax purposes and an individual applicant to open and operate this account.
  • Open your account in branch, agency or online. Existing customers who wish to transfer funds from their maturing Principality Fixed Term ISA to open this Account can do so in branch, agency, online or by post.
  • The minimum balance is £500 and you can save up to the current annual Cash ISA limit of £20,000 (plus transfers-in of existing ISA balances) in this tax year. The minimum balance must be maintained to operate the account.
  • You have 5 business days from the account opening date in which to make your initial deposit. If you have not made your initial deposit in this time your account will be closed.
  • You can keep making deposits while the ISA remains on sale.
  • The ISA will mature after 18 months on the anniversary of opening.
  • Manage your account in branch, agency, online or by post.
Can I withdraw money?
  • No withdrawals permitted prior to maturity.
  • Early closure or transfer to another ISA provider permitted subject to 150 days’ loss of interest. If you haven't earned enough interest to cover this, this will be taken from funds in your account and means you will get back less than you originally deposited.
  • We will write to you before your ISA matures to let you know what other ISAs we can offer you.
  • If we don't receive any instructions from you before your ISA matures, your ISA will be transferred to our Variable Rate Cash ISA or its nearest equivalent.

  • In certain circumstances we may refuse an instruction to operate an account. These circumstances are outlined in the Savings Terms and Conditions.
