I've a mate in the cabling industry so he did mine.
It came down the side fo the house, through the wall and into the hallway. Nowhere near a plug socket.
He cut it outside, attached a CAT5e cable and ran this around the front of the house and into the front room through an air vent and fit a new socket there.
It really wouldn't be hard to do yourself with the right tool and cable.
I'll be doing it again when I build my office and run it under the stairs, from there it will go out to the lounge and the office space via a couple of cat 5e cables
