I want to put a shelf up in my home office, on a wall which also has the consumer unit on it. Is this a total non-starter, or could I safely avoid drilling into a cable by using those plasterboard fixings which screw into the wall? I’ve tried using a Bosch detector to map where the cables are, but it seems to light up like a Christmas tree without any pattern I can map out (maybe it’s just cheap !).
Thanks in advance for any advice.
