Important Information: Structured deposits offer you the potential to earn higher returns than you would with a regular savings account. Your returns are based on the performance of an index or commodity. If the investment does not perform well you may receive no income or capital growth, but you can be confident that your capital will be repaid. You have no access to your deposit during the term of the account, typically 3 to 6 years but your original capital will be repaid in full at the end of the term. In the event that the deposit taker is unable to repay your initial investment and any returns stated you may be entitled to compensation from the Financial Services Compensation Scheme (FSCS) depending on your individual circumstances.
