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.

Cash ISA interest rates vary from one provider to the next, but the best Cash ISAs will suit your needs. They vary, and include the following features:

  • Opening balance - some providers ask for £1 while others require the full allowance as an opening deposit
  • Access to your money - usually, the more limited the access, the higher the interest rate
  • Previous ISA balance transfer - some providers won't let you transfer funds from another Cash ISA
  • Tiered interest rates - Sometimes, the higher the investment, the higher the interest you get

Because deals vary, it is important to shop around. To find the best Cash ISAs for you, compare some of the leading providers using the table below:
