I have just received a quotation from Northern Power Grid for the electricity supply. My house, in the garden of my current house, is at the end of a small cul de sac and will be the 5th property - others having been built many years ago.   As there are houses just the other side of the road from me, using NPGs calculator my estimated costs were between 1 and 2 k depending which side of the road the electricity supply was on.     The quote is for over £8600 - Not connecting t
