The term ISA stands for an Individual Savings Account. Allows you to save tax-free into a cash savings or an investment account. There’s a few different types of ISAs depending on what you need from them. So for example, there's a stocks and shares ISA for general investing and a lifetime ISA, which you generally would choose if you're trying to buy your first home. So make sure you look at what's available and that you also understand what your goals are first.
