Iíve just moved into a 1970s house with some unique phone wiringÖ The external phone cable appears in a cupboard where the meters are. Thereís no master socket; instead it is crimped onto another section of wire, with the crimps hidden inside a small BT-branded plastic box, dangling loose on the floor. This second cable is heavily worn, with the outer insulation missing from several stretches. It leads to another identical plastic box by the stairs, where itís crimped onto a new cable and heads to an old-style master phone socket. Inside this socket, the socket itself has been bypassed, with the cables crimped again onto another wire, heading upstairs. It runs through the plaster to a wall socket (not a master) on a wall Iím planning to knock down. Into this socket, a consumer phone extension lead is plugged. This makes its way through a wall and under the carpet, finally at the end of it is an official MK1 Openreach master socket.
Unbelievably I get a stable 75Mbps connection over this, and Iíd leave it alone if it wasnít for the fact that I need to knock down the wall with the non-master phone socket. Given the lack of a proper master socket, where does my responsibility start for this mess? My phone line and internet are with Sky if that matters.
Thereís an unused TV coax which runs from the cupboard where the cable first arrives, up to the location where Iíd like the master socket to finally be. Iím inclined to pull this out, and use its holes to run a single new phone cable. What would Sky/Openreach charge me to do this? Alternatively, am I permitted to do this myself?
