The truth about rewiring and re-plumbing your home
Start with the age of the house. If you see rubber cables and round sockets the system may not be unsafe but you should lunge for the Golden Pages. You many have square and round outlets side by side in an older house as the house may have been rewired, but when? Every socket, ceiling fitting and switch in a home should be replaced every ten years, (five in the kitchen) as they are working features that burn and wear after a time. You should have your wiring fully checked at least every 5 years by a qualified electrician
