We came across this today. The homeowner admitted he was no electrician and was concerned about the number of junction boxes and wires generally in the loft space. In this photo of an area less than 2 square feet there are 9 junction boxes (many, many more throughout the loft), cables twisted together and covered in insulating tape, a poorly connected armoured cable from 16mm T&E and of course the 13amp plug for the loft lights.
