Trying to look at switching supplier - first of all they all bloody want you to have a smart meter but secondly there are sooo many companies out there now that I don't know where to turn! Been on Martin Lewis but my head hurts! Igloo, octopus, out fox the market... Who are these people and what's happened to the big 6? Is ok to just go with some rando now or will i get shafted... HELP!!!
