As I am an elderly lady, one of my sons dealt with the electrician. He cannot remember any discussion with the electrician about a re-connection charge. In fact, he is certain it was never mentioned.
RE-reading your question. Yes, he did disconnect the power in the house....the electrician, I mean.
Thank you Alex. It was an expensive re-wire but the cost of same was agreed. I am relieved that I am able to stand my ground where any further charges are concerned..
