Looked at Talk Talk site and unsurprisingly not very helpfull .
Could try
this for starters, but the lack of any clear link to what you require dosnt bode well.
I would haveguess dialling 150 from their line would put you through to Talk Talk sales, but that may not be convenient for you to do.
Seeing as you will still be left with the cost/issue of installig the extension wiring , any particular reason you need to get the socket replaced? Extension wiring can be either hard wired to the existing LJU or simple plug in extensions can be used
