It does beg the question why Sky feel the need to charge £30 for installation if you already have a Sky+ box being replaced, when all that is needed is to disconnect one box and connect the other - i can do that myself as i doubt any Sky engineer will connect up to my receiver so i'd end changing connections anyway. Admittedly, they've dropped the price of a new box accordingly, but why when i already have a Sky+ multi-room subscription, should i be hit for £30, just so they can take one of my old boxes away and recycle it to another customer? It doesn't cost £30 to overnight courier the box to my house, just send me the box and i'll do it myself without thier engineers passing my details on to replacement warranty companies who bug you every 5 minutes to take out their "superior" service.
