I will be converting my loft come spring time. Nothing fancy but it will require two 6m RSJ to hang the floor from. The steel supplier has a wagon with a Hiab type crane which will lift them to roof height, BUT there are two drop wires from a pole 30m away that cross my property to the houses next door. .One is about 3m the other 6m from my roof/ scaffold insertion point at a height of 4-5 m. This effectively prevents safely lifting the steels without damage to the wires. Are the service providers obliged to either temporally or permanently move them.? I have Lived here for 30 + years and have checked the deeds for any Wayleive which is none. I would appreciate advice from you learned gentlemen if you have any.
