Subfloor services – loose wiring


Poor installation; damage by tradespeople


  • always tell someone when you are going to work under a floor. Make sure you take a torch with you and if possible a mobile phone

  • turn off the mains electricity at the switchboard before working on wiring under the floor

  • use proprietary cable clips (typically made of bendable aluminium or solid plastic) to attach loose wiring to framing. Clips are available in different sizes and often come with steel pins for fixing into timber framing

  • if wiring passes through or sits alongside polystyrene insulation, install a sleeve so the cable is not in direct contact with the polystyrene
