I don't really care about them going bust the regulator sorts it all out and often these smaller companies are the cheapest options and that is all I'm interested in, last time I managed nearly the full twelve months with who ever it was who went bust just annoying that this time I only got cheap prices for a month! Apparently EDF are guaranteeing we will all save money with them compared to our GEN prices so that could be a winner or I'll just switch again for another cashback hit.Sadly this is the reason I stay with the larger ones, maybe not quite the big 6, but the ones that have been around a bit.
