At some point we'll need to sort out phone cable coming into the house, as the joint between external and internal cable is boxed in and in accessible. I don't really know how exactly to do it, but it seems to me unlikely that there'll be enough slack to relocate the junction box without extending or replacing the internal cabling. Since I would quite like to relocate the master socket, I was thinking of running cable behind the plaster from the proposed new location, popping out of the plaster again near to the mystery junction box. I did similar in the past when installing a second line, in fact at that time the BT guy left me some cable saying that they wouldn't be able to go wriggling through crawl spaces etc but if I could get the cable in place he'd come back to connect it.
So what's their practice at the moment, will they be OK with me pulling the cable, or do they have to run it all themselves? Equally is there any issue with cable running behind plaster?
