What if my mortgage interest rate changes?

If you are coming to the end of your promotional rate period or it has already ended, your interest rate will switch to the standard variable rate if you have not made alternative arrangements. This means that your mortgage payments could go up or down each month, so it’s best to get in contact with us as early as possible to discuss your options.

To find out how your monthly payments will be affected by a change in interest rate you can use our mortgage rate change calculator. You’ll need a few details about your mortgage, such as the outstanding balance, term of mortgage, current interest rate and your new interest rate.

With this calculator, we can give you an idea of how changes in interest rates can impact your mortgage payments.

This calculator provides an indication of the possible change in your monthly mortgage payments in the event of an interest rate change. All figures are indicative and for illustrative purposes only.
