      Further information

      • The Annual Equivalent Rate (AER) is the rate you would receive if the interest was paid and compounded annually. It is a universal tool that enables you to compare different savings products. The rate is calculated after the annualised Management Fee is deducted.
      • Gross interest is the annual rate of interest to be paid on a deposit account before taxes or other charges are deducted. You are responsible for paying any tax due to HMRC. Your tax liability depends on your personal circumstances and may be subject to change.
      • Deposit accounts available through Cash Savings include accounts operated under Shariah principles. This means that interest cannot be earned, only profit. The profit shared is the expected profit rate at the time the account is opened. Further information can be found on the platform.
      • Under certain circumstances, you may be able to get a better rate for the same product by going directly to the underlying bank.

      Your money is protected

      All banks on our panel are authorised by the Prudential Regulation Authority (PRA) and regulated by the PRA and Financial Conduct Authority (FCA) and pay levies into the Financial Services Compensation Scheme (FSCS). In the unlikely event that anything happens to one of your chosen banks, the FSCS automatically refunds eligible deposits of up to £85,000 per customer per banking institution within seven days. If you hold more than £85,000 with any one banking institution (even if it is spread across several different products / accounts, or even different arms of the same banking institution), you are unlikely to be able to recover the difference.
