Hi, I have also had such conversations with my manager.
It was decided that if there were no people at work that I could contact to let them know that I had returned safely, then I was to telephone my husband or close relative before and after such a visit.
It is not an easy policy to deal with, particularly in small teams and in the future we may be working more unsocial hours. However I do feel that we need to be sensible about this and not let it get in the way of our work. We should all be risk assessing all our home visits beforehand and should try to keep most of them within normal working hours.
I would value others views on this.
