For a fault, note whether it happens every time or only occasionally, whether one fitting or several are involved and what was in use when you noticed it. If a light flickers, a switch feels loose or a socket has stopped working, describe those observations plainly. Do not remove covers or attempt electrical repairs yourself.
For a planned installation, list the room, the equipment you want fitted and whether an existing fitting is being replaced. For testing or inspection, include the type of building and why the work is being considered. These details help the team understand the request; they do not establish a diagnosis or define the final scope.
