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 the Bank of England expected to slash interest rates again this year, it could be a good idea to secure favourable rates now by locking your savings away into a fixed rate 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.
