If so, what is the experience with first:utility? Have always been with one of the big 6, and Scottish Power is not a lot more so could go with that?
Current supplier (SSE) has been no hassle and not projected to be hugely hugely more so also tempted to stay owing to natural laziness and fear we will struggle to get current credit back (They reduced payments a few months back).
Also, if projected use is an underestimate (probably unless we get another mild winter), how do I check what effect that will have on savings/cost?
I am clueless in case you hadn't worked that out already, advice/experience welcome
