You have proved my fault into the BT network, will I still get a bill from them?

Ordinarily once I have proved that the issue within the BT network, then no further charges will be applied by BT or your service provider. However if there has been damage to their network within your land eg if an overhead wire has been damaged by tree owned by you, or the wire has been brought down by a vehicle on your property then they may charge for the repair, as this will probably involve replacing it right back to the pole. This is outside my control and I will give appropriate advice on my visit.
