Have a sky HD install booked for next week, dish is on the roof of a 2 storey house so special heights team are coming. I specifically asked on the phone that the engineers do not anchor bolt themselves to my house as it has just been rendered. None of the people on the phone knew what I was talking about. Do sky engineers still bolt themselves to the wall? is it health and safety policy or not? I don't want them showing up and then having to send them home because they insist on bolting themselves to the wall.
