If you do not pay in time we can charge interest on what you owe at 2% above the base rate of HSBC bank plc. We will use the base rate in force on the date of the bill and charge interest on a per annum basis calculated daily, until you pay. If you don't pay a bill we terminate provision of the service we are providing to you. The application of interest on late payment will not be applied where you have a genuine dispute with us and that before the date by which the bill should have been paid we have received written notice setting out the details of your dispute. Receipt by us of this written notice must be proven by you.
