Electrical wiring ages, just like everything else in a building. Old or poorly maintained wiring can be inefficient, prone to faults, or even dangerous in extreme cases. It may not support the number of appliances and devices most households use today.
Asking about the age of the wiring, and whether it has been updated, gives you clues about safety and potential future costs. If it’s very old or there are signs of DIY changes, you may need an electrician to inspect and possibly upgrade parts of the system.
Modern wiring, proper earthing and a reliable distribution board with MCBs and RCDs (or local equivalents) make a big difference to both safety and day-to-day reliability.
Knowing the state of the electrics helps you negotiate price, plan upgrades, or decide to avoid a property that would need more work than you want to handle.
