My plasterer has requested I do not make holes in the ceiling for down lights until ceiling is plastered. Issue is I cannot get into the ceiling void as upstairs floor has underfloor heating. ( Ceiling is not yet boarded out). Is there an easy way of finding the cable terminations.? I have thought of taking a reference point and measuring position of each location but on a 40 sq mt ceiling divided into 3 banks of lighting this could be a long job and possibly prone to error. Other thought was to fix a clout clout nail at the location and use metal detector, but as the ceiling has resilient bars I guess the detector will be fooled. Does anyone have a neat solution to this issue?
Thank you
