What to expect when you underpay

Any overpayments you make within your mortgage’s overpayment allowance will contribute to and build up an overpayment reserve.

You can underpay on future monthly mortgage payments until your overpayment reserve is empty.

Your monthly payments will be recalculated at the end of the underpayment period. They may increase as a result.

You will still have interest added to your mortgage throughout this period, even while your payments are reduced.

Before your underpayment period ends, we’ll write and tell you what your new monthly payment will be.
