Landlord electrical safety certificate

Grumpy
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"?

    The IET guidance is a little vague. It suggests "sealing" around all cable entries, although the regulations only require IP2x, or IP4x on the upper surface. Sealing is also needed, if you are going to do it as a fire prevention measure around the lid, and the MCB cover. Unless you keep all air out, sealing does almost no good at all! I don't know who wrote the "guidance", but I have yet to see it fully followed, because it makes the CU unusable! Perhaps the manufacturers should provide seals around the lid and cover, or perhaps intumescent seals would be better.
