What are fixed rate ISAs and how do they work
Fixed rate ISAs offer a guaranteed interest rate on your savings for a set period, typically from one to five years, shielding you from rate fluctuations. These cash ISAs allow up to £20,000 tax-free savings per tax year, as confirmed by NatWest in 2025. Unlike variable rate options, your fixed rate ISA rate stays constant, providing predictability but limiting access to funds until maturity.
Key benefits include tax-free interest earnings and protection from falling rates, ideal if you expect the Bank of England base rate to drop from its current 4.75%. For example, locking in now could secure higher returns amid projected cuts. However, early withdrawals often incur penalties, such as loss of interest.
To understand tax-free savings rules, interest grows without income tax or capital gains implications within the ISA wrapper. The allowance resets each tax year on 6 April, enabling fresh contributions annually. Compare this to easy access ISAs, which offer flexibility for withdrawals but lower average rates around 4.51% AER versus fixed options up to 4.27%.
