Fibre optic broadband install nightmare

[mentalnerve]

We've finally got fibre optic available in our area, and i duly signed up with talk talk. I was told by the customer services bloke that an engineer will come and install it in 2 weeks time. . What they failed to tell me and what ive prob not bothered to read in the t&c's was what was involved in the install. Now in theory, its pretty straight forward cos ive done a googly search and found out that they upgrade the bt master socket and connect up your router. Your router has to be connected to the master socket (not any other extension socket) or via data cable extension.

Now upon reading the google search results i realised that the friggin master socket (from which i have about 8 extension sockets around the house ) is located in the utility room just above the skirting board behind a kitchen unit (recently fitted by my klutz of a carpenter, who also covered the hot and cold valves of the washing machine!! ) so basically inaccessible.

My question is to all you clever clogs out there, can you convert an extension socket so thats it becomes a master socket.
