I was just wondering how often everybody else changes their provider for electricity and gas if at all.
I recently changed to Scottish power because of how good their Quidco cashback was and they were the cheapest in my area.
With the prices being so close between a few of the companies is it worth switching and earning a little extra through quidco?? If it is how long is it reasonable to wait before changing again??
Any thoughts or experience on this would be great.
