I got a flow of emails telling me that they were looking for a better deal for me. Finally they emailed me to say that a switch was under way and that I had 14 days to cancel. I checked out the proposed new supplier on line and decided to cancel (we're waiting for LAMB to action this). We were not entirely confident about the quality of customer service from the new supplier, there are reports on the web of its customers having difficulty getting refunds when they have overpaid their account. Service from our current supplier has been exemplary. Incidentally, none of the other price comparison sites threw up any offers from the new supplier which we thought was, shall we say, interesting. We were also not sure what role LAMB might play if the switch went wrong for any reason. If they are just brokers, then they will do nothing and we would have a mess to clear up - see other comments on here. Too risky all round, best do this sort of thing yourself, it's not very difficult.
