Our Best Rate Promise
Our fixed rate accounts benefit from 'Our Best Rate Promise', which means if we increase the interest rate for the account you have applied for at any point in the 14 days following the opening of your account, you will automatically receive the higher rate. If we reduce rates don't worry, you will still receive the same rate that you applied for. If our rates do change, you do not need to contact us, we will do everything and then send you confirmation of the new terms applicable to your Fixed Rate Saver or Fixed Rate Cash ISA.
