This is probably a very amateur question...
What happens about utilities in a second house which you are not ready to move in to? For a few months DM will be popping in, measuring, decorating, getting carpets fitted etc.
Will a bill from the current supplier be sent by post at some point?
Does she formally open a utilities account when she moves in, and pay the difference in the meter reading?
Will they cut the power and gas to the house at some point?
I'm hoping someone will have done similar and will know the routine!
