An ISA is an Individual Savings Account. It is essentially a wrapper around your investments to allow you to enjoy income earned from up to £20,000 investment tax-free.
There are 4 types of ISA; Cash, Stocks and Shares, Lifetime and Innovative Finance ISA. You can diversify across the components by an amount of your choosing, or you can choose to invest all your entitlement into one product. We cannot advise on individual circumstances, although we can assist you in providing information.
