What is a fixed rate cash ISA?

Fixed rate ISAs allow you to earn a guaranteed rate of interest on your savings without paying tax on that interest. They are normally offered over 1-3 years, with the level of interest staying the same for the entire period of the ISA. For the 2022-23 tax year, over-18s can place up to £20,000 in an ISA.

With a fixed rate ISA, the trade-off you make for the guaranteed rate of return is that you agree not to access your savings during the life of the product. Legally, ISA providers do have to allow you access to your money if you need it, but they can (and normally do) charge heavy penalty fees for this.

Benefits of fixed rate cash ISAs

Fixed rate ISAs allow you to earn a guaranteed return, making them a good choice for those who do not want to take risks. You can normally roll the ISA over when it ends, moving your savings straight into a new fixed rate ISA if you do not need to use them when the original product term ends.

Alternatives to fixed rate cash ISAs

One of the main alternatives to a fixed rate ISA is an Easy Access ISA. These allow you to pay in and take out money whenever you like and offer a variable rate of interest in return. This gives you much more flexibility with your savings, but there is no guarantee how much you will earn in interest and it is often less than you would earn with a fixed rate ISA.

Another popular alternative is tracker rate ISAs. These give you a rate of interest which is tied to a base rate (often the Bank of England base rate) plus a set extra percentage. If the base rate moves up, your interest rate will move up in line with it.

A tracker ISA means that if interest rates increase, so will the rate you earn on your savings. By comparison, a fixed rate ISA will pay exactly the same interest rate even if general interest rates go up.

However, the starting rate on a tracker ISA will tend to be lower than for a fixed rate ISA, so which is the better option will normally depend on how likely you think it is that interest rates will rise over the lifetime of the ISA.

Fixed rate cash ISA interest rates

The interest rates on fixed rate ISAs can differ considerably between providers, so it is essential to look at as many different products and providers as possible before making a decision.
