I have just again re-tested an installation that was tested a month before. The installation is done before 1992 and the previous electrician excuses is "reasonably safe" and "is not covered pre-1992"! Why test the installation then? It is of my opinion that it is bull s..t that you can hide behind the fact of an installation being done before 1992 and "reasonably safe". Sorry guys we contractors need to take pride and stand for good practice, safety & quality installations...... How can leave a house with a fuse board, earthing issues, open wiring and say you have tested & found all in order, i will not stay in an house with such a useless COC issued or maybe i am taking it too far?
