There are different types of structured ISA – where the annual ISA allowance is used to invest in a structured investment. There are structured ISAs for income and growth, and ISAs where capital is protected or at risk.
Structured investments will normally be linked to the performance of an underlying index, such as the FTSE 100 and can offer a level of defined return. Prior to making a decision to invest in a structured ISA you should ensure you are familiar with the risks associated with that product and read the product brochure.
