What we found

  • Exposed single insulation and loose connectors under kitchen base units; one cable with no connector at all
  • Twin and earth laid in the floor screed with no mechanical protection
  • LED floor lights with bare cables and no circuit protective conductor continued to metal fittings
  • Earths twisted together unsleeved in the appliance grid switch; oven cable came out of its terminal
  • Loose neutrals and damaged cables on the ground-floor sockets; a broken double socket
  • Board incorrectly labelled; the previous EIC ticked board replacement but recorded only 3 circuits and listed Type AC RCDs where Type A were fitted

What we did

  • Visual audit of the extension works with a written list of concerns
  • Full EICR of the installation
  • Re-terminated the kitchen appliance grid switch
  • Dropped and re-made ground-floor sockets to cure loose neutrals and restore continuity
  • Replaced the damaged double socket
  • Made bare cables safe under the units
  • Tested both Type A RCDs (pass)
  • Relabelled the consumer unit correctly

Equipment used

  • Kewtech KT63DL tester
