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.

You should make sure you do a cash ISA interest rates comparison before opting for any particular deal, because rates vary considerably between providers, and depending on the type of cash ISA you choose. Fixed rates usually offer the highest rates, while instant access still offer competitive returns if you don't want to lock your money away. For potentially higher returns than you can get with fixed rate ISAs, you might want to consider structured deposit plans.  

There are two types of ISAs:
