I need to put in an underground telephone cable from a new build house. The distance from house to road up our private drive is approx 35m. The telegraph pole with the main line is approx 4m from our drive entrance. I'm planning on getting my own ducting grey plastic and the electric guys are happy for me to drop the duct into the trench I dug for them to put their new electric cabling into. The BT duct wil go from our house to the actual pole. Openreach have quoted me £2,300. I'm told only they can supply the cable even though the BT engineer has said he can connect it up once the cable is in place. What can I do? It seems a colllosal invoice!! Help please.
