At present BT customers that pay by direct debit (DD) or Monthly Payment Plan (MPP) receive a discount to their standard tariff. From 1 May 2007 BT will be changing the way that this charge is presented to its customers. The discount will in future be included in the standard rental tariff and instead a charge will be shown on bills for customers that do not make payment using an automated method. BT will also be increasing the charge by 50p a month.
