This summer, when the wife is on holiday, I intend to take down the
manky lath & plaster walls and ceiling in the main bedroom and put up
plasterboard. This will enable me to run some extra cables for sockets and a
telephone extension in the kids room so they can connect their computer in
the void.
It would be handy to run a network cable from the box room (my office)
to the kids room to exchange data in the void, rather than trail a data
cable along the landing. Can I get a diy installation of sockets and cabling
anywhere?

Thanks

Kevin
