Are you worried about insulation derating the cable or chemical effects on the

Roger it is about derating the cable, I know the PU should not react with the cable. Previously it was buried maybe not intentionally in a thick lump of plaster which fell away when I pulled the old floorboards out and was finally able to see the situation.

Owain, I take it from the smiley moving the cutout was not a serious suggestion, apart from involving the DNO again there is nowhere for it to go things are very tight around that area with the CU and meters.
