Landlord electrical safety certificate

Hi all, my father in law has a rental property that was completely rewired and with new split load CU five years ago. The installation is now due an inspection. Will the fact that the CU is plastic constitute a "fail"?

  • There are plenty of those above Colin, and some of them not in the spirit of BS7671, which defines the inspection routine. Does the NICEIC really expect one to use their codebook codes? If so I assume they also accept responsibility where this leads to a poor, or worse incorrect outcome of the EICR. But then I cannot see them other than the BS7671 definition of the Inspector, ie competent and therefore responsible. I bet there is a disclaimer there somewhere.


    I do not understand this fascination with plastic CUs being unsatisfactory and needing replacement (at great expense with AFDDs and surge suppressors). The real problem is very well understood and it is not the plastic or fire containment. It is simply poor connections on potentially high current cables. Correct this problem, particularly in the manner I suggest, and the problem is gone forever. The cutout, CU, or anything else do not catch fire without cause, and of the 20 million or so installations with plastic CUs, a tiny number have caught fire, probably for known reasons. This fireproof cupboard lark does not do much useful unless a suitable fire alarm system is fitted, it only delays the onset of a serious fire. It seems to be assumed that a non-combustible CU will stop any spread of fire, that is only true if the complete contents are properly sealed (to exclude oxygen) and also completely non-combustible, neither of which is true. Cable insulation, paint, MCBs etc will burn given a good air supply and sufficient temperature, and several hundred grams will make quite a good fire once started properly.
