External wall insulation and mains supply

Former Community Member
Former Community Member

I'm having external wall insulation installed on my house, and the mains supply to the house is via an overhead cable. The insulation installers have put the insulation over the mains supply cable, i.e. where it's clipped to the wall between bracket and meter box. The DNO is Western Power. 

My question is, is covering the mains PME cable with 90mm of insulation acceptable practice? 

Thanks, Pete

    PME is unlikely to be relevant, but this MIGHT be a bad idea for other reasons.

    Firstly the thermal insulation will reduce the current carrying capacity of the cable which MAY then be insufficient.

    The now concealed cable could be damaged by someone unaware of its presence who drills into the wall. This can result in the death of the person, setting light to the building, and expensive repairs.

    The concealed cable is vulnerable to tampering to facilitate theft of electricity. 

    I would approach Western power at an early stage.
