What is the interest rate?

Can NatWest change the interest rate?

Yes, we may change the rate up or down. There are a few reasons for this, such as a change in the Bank of England base rate. You can find a full list of reasons for an interest rate change in section 9.2 of the Savings Account Terms. We’ll give you at least 14 days’ notice if the rates are going down and your balance is £100 or more. Otherwise we’ll tell you before or shortly after the change. You can find more details about how we’d tell you about a change in section 9.2 of the Savings Account Terms.

What would the estimated balance be after 12 months based on a range of deposits?

How do I open and manage my account?

  • Each month your balance must grow by at least £50 to earn interest. If your balance grows by less than £50 in any month, you will not earn interest. If a regular payment is received after the second last business day of the month it will count towards the following month.
