There are many cases of people not receiving bills for years, so waiting is not a good option. Asking the neighbours is no good either, since, although the gas comes through the same pipes (as the electricity comes through the same wires) you can all be paying different suppliers. Wasn't it easier when there was one gas company and one electricity company to choose from? They may have been inefficient, and we may have been paying more than we needed to, but we didn't have these touts knocking on your door trying to get you to change, and everyone paid the same, so you didn't meet people who had changed supplier and gloated about saving �100 a year. TCL-Mumping seems to know what he/she is talking about. Do that.
