ISAs are some of the best savings vehicles you can use in the UK, as they allow for up to £20,000 of tax-free savings a year.
With a multitude of ISA reforms in the Autumn Budget, it might be a good idea to secure favourable rates now by locking your savings away into a fixed rate cash ISA.
However, make sure that you’re getting a good deal on your interest rate and that it is above inflation; otherwise, you’ll be losing money in real terms.
