What is a 5-Year Fixed-Rate ISA?

An Individual Savings Account (ISA) allows you to save and invest money without paying income tax on the returns. A fixed-rate Cash ISA locks your interest rate at a set percentage for a predetermined duration—in this case, five full years.

Unlike easy-access accounts, where banks can alter rates at a moment’s notice based on base rate cuts, a fixed-rate account guarantees that the percentage you sign up for today is what you will earn until the term matures.
