What happens to a Fixed Rate ISA at the end of the fixed term?
This depends on the provider and their terms and conditions. Usually, Fixed Rate ISAs revert back to the provider’s standard variable rate product. You can leave it as is, re-fix the ISA at whatever their current fixed rate offer is, or transfer it to another ISA provider (either variable or fixed rate). Usually (but not always) the standard variable rate is not very competitive, so it is beneficial to compare other available ISA rates to maximise your savings returns.
