What is the interest rate? Tax-free^ each year / AER† (Variable)
£1 - £25,000              3.65%
£25,001 and over     3.70%

(See the meanings of 'Tax-free' and 'AER' at the bottom of this page.)

Interest is calculated each day on the money in the account and paid on 6th April every year.
Can Principality change the interest rate?
  • Yes, variable interest rates can go up or down.
  • If you have £100 or more in the account, we will give notice of any reduction in interest rates at least 14 days before the change takes effect.
  • For more information, see the section Changes to interest rates in our Savings Terms and Conditions.
What would the estimated balance be after 12 months based on a £1,000 and a £25,001 deposit? This is based on no further money being put in or taken out of the account and no change to the interest rate:

£1,000 would be £1,036.50
£25,001 would be £25,926.04
How do I open and manage my account?
  • You must be 16 or over and a UK resident (see your Triple Access Cash ISA account terms).
  • You can open the account in branch or at an agency.
  • You must keep at least £1 (the minimum balance) in the account.
  • You cannot pay in more than the ISA Allowance each tax year. The ISA Allowance for the current tax year (2023/2024) is £20,000.
  • You can transfer unlimited amounts from ISAs from previous tax years, as these are not part of your current year’s ISA allowance.
  • You can manage the account in branch, at an agency, by post, or by using the online service, Your Account at
Can I withdraw money?
  • Yes, you can make three withdrawals from your ISA every tax year.
  • You can close or transfer your ISA at any time without losing interest.
  • This is a flexible ISA. This means you’ll be able to take money out of it and replace that money before the end of the same tax year, without the replacement contributing to your annual ISA allowance.
  • We won’t inform you if you make a withdrawal that reduces the money in the account, and a lower tier interest rate then applies.
Additional Information
  • Service charges and costs may apply to the account. These are set out in our Tariff of Charges.
  • In certain circumstances we may refuse an instruction for using an account. These circumstances are set out in our Savings Terms and Conditions.
  • The tax treatment of your savings depends on your individual circumstances and may change in the future. This is set by HM Revenue and Customs (HMRC).
  • The interest rates quoted above were correct on 10/08/2023.
