1 Year Fixed Rate Cash ISA

Interest is calculated each day on the money in the account. You can choose whether interest is paid: 

• Annually, on the anniversary of your ISA opening. 
• Monthly, starting one month after the date your ISA is opened, and then each month after that.

No, the rate is fixed for one year until the ISA matures (when the account comes to an end). 

£1,040.00

This is based on: 

• You choosing to have interest paid annually and added to your ISA.
• You not making any further payments into the account.

This calculation is for guidance only, to show you what a future balance could look like. It does not consider your individual circumstances. 

• You must be a UK resident and satisfy the minimum age requirements to open a cash ISA (see your 1 Year Fixed Rate Cash ISA account terms). 
• You can open your ISA in branch, at an agency or online. If you want to open this ISA with funds from a Principality fixed term ISA that has matured, you can do this online, in branch, at an agency, or by post. 
• You must keep at least £500 (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 (2025/2026) is £20,000. You can only pay your ISA Allowance into one Principality cash ISA in the current tax year. 
• You can transfer unlimited amounts from ISAs from previous tax years, as these are not part of your current year’s ISA allowance. 
• We must receive the first payment into your ISA or a transfer in request within five business days of it opening. If we don’t we may close the account.
• You can keep making payments into your ISA while we are still offering this ISA to customers. 
• Your ISA will mature one year, on the anniversary of the account opening. 
• You can manage your ISA in branch, at an agency, by post, or by using a secure online profile with Principality. 

No, you cannot make withdrawals from your ISA before it matures. 

If you close or transfer your ISA before the end of the fixed rate term (within one year), you will lose 90 days’ interest. If you haven’t earned enough interest to cover the 90 days’ interest it will be taken from the money in the account. This means you may get back less than you originally put in. 

We will write to you before your ISA matures to find out what you want to do with your money. 

If we don't receive any instructions from you before your ISA matures, we will move your money to our Variable Rate Cash ISA or the nearest equivalent we offer at the time. 

Service charges and costs may apply to your account. These are outlined 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). Further information can be found at gov.uk.
