The cost to rewire a house can be a significant factor when buying a property to renovate, or if the electrics in your current home are past their best.

Generally speaking, if the wiring in your property is over 25 years old, then it’s highly likely it will need to be renewed. Warning signs can include frequent blown fuses, slight shocks from switches or sockets, and lights which persistently flicker or dim. If your wiring is unsafe due to age or faults, the consequences can range from your entire electrical system regularly tripping to lethal shocks or a house fire.
