Hello just a quick one I have moved my tv away from my wall socket to the other side of the living room, I am going to buy an extension cable that is long enough to run from my wall socket under my skirting boards to the tv box to plug into it, I just want someone to point me into the right direction to make sure I am buying the right extension cable for the job, once again one end is going into the virgin wall socket the other into the back of my tv 360 box any help would be amazing
