Fixed rate ISAs at a glance

Fixed rate ISAs offer a secure way to save your money with a guaranteed interest rate for a set period. Here are the key features of these savings accounts:

  • Guaranteed interest rate: The interest rate will not change for the term of the product, so you know exactly how much your savings will grow by.
  • Tax-free savings: You don't pay tax on the interest earned, allowing you to keep more of your money.
  • Fixed term: If you need to access your money before the end of the fixed term, you will incur an interest penalty.

What is a fixed rate ISA?

A fixed rate ISA is a type of savings account where you put your money away for a set time, typically between one and three years. During this time, the interest rate stays the same, so you know exactly how much your savings will grow. 

With a fixed rate ISA, you don’t pay tax on the interest you earn, which means you get to keep more of your money. These accounts are a great way of saving tax-efficiently and fix the interest rate you earn on your savings.
