Hi Susan, like for like electrical repairs or replacements can usually be done without bringing the electrical installation up to current standards. Any new work should be done according to the current wiring regulations and this includes the earthing and circuit protection arrangements. Water and gas pipes should be bonded to the main earth terminal close to where they enter the dwelling. This is usually accomplished with earth clamps that fit round the pipes and 10mm square earth cable. Under fault conditions this helps ensure that dangerous voltages do not occur in pipe work in the property. This is an important safety measure but obviously can cause you additional expense and disruption to implement
