To help customers, and in response to demand, BT now recommends the 10 numbers which they have recently called which would give the biggest savings.
Of course, calling patterns change and, over time, some of those numbers may be called less frequently or not at all.
BT include everyone's home number as an 11th Friends & Family number so that those customers who telephone home, using their BT Chargecard, can benefit from the 10 per cent discount.
