Our house is a strange one, it DID have all the extensions wired in, but there was a terrible noise on the line. The BT master socket WASN'T a BT master socket, apparently the people on site have/had "done a deal" with the BT engineer so the house builders provided the sockets, the first socket in the house isn't the standard openreach (or previous BT version) of socket at all, just a plain, regular socket.
I did some googling and just disconnected the bell wire, which seemed to have cured the noise on all the lines. To be fair, the electrician did spend some time trying to fix the noise, but came up blank, so I ended up DIYing it.
