Best fixed rate cash ISAs – earn up to 4.32%
We look at the best fixed rate cash ISAs on the market right now for savers who are willing to lock their cash away for guaranteed tax-free gains

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.
The Bank of England held interest rates in June, so it's 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.
