How ply-able is the main incoming cable to the head in a house? Myself and my dad moved one 2 meters once and if i remember correctly the outer sheath was lead but this was under floorboards where as the one im asking about is concreted in so will need to be gunned up........anyway a job has come up which i am going to look at at 11am this morning with my father inlaw and where the ccu,meter and head are situated in an understair cupboard the lady wants to put a door so the afore mention ccu,meter and head need to be repositioned to allow for said door.
