Why would any homeowner or operator intend to have an Electrical Installation Problem Record? An EICR, for short. Well it is a fact that the circuitry in a building deteriorates gradually. However, in one regard, it usually weakens really gradually. It is not such as the oil in your automobile, as an example, which requires changing every many thousand miles. No, electrical wiring weakens over many years, and the process is so slow-moving that we never ever consider it. It can be affected by the amount of use that it has as well as the environment in which it exists, but the process is still sluggish. This is why it really usually goes undetected and not even thought about. The various other point is that the electrical wiring itself can not even be seen. It is hidden in the walls, under floors, and also in ceilings, so we don't also consider it. The old expression is "Out of sight, out of mind". Just as long as every little thing works, most people more than happy enough...
