daveh75:It doesn't require any extra cabling etc if you're just swapping out your sky+ box for an HD one, but if your an existing customer they will charge you a £30 set up/connection charge for the privilige.... unless you take up the Hd/multiroom offer,then the charge is waived.
This is not entirely accurate. You could buy a Sky HD box off ebay and connect it yourself. You then just phone Sky and say that you have swapped your box and you want to pair your card with the new box. They will do this over the phone. Although an HD box on ebay might cost £150. You could get the deal they have on offer at the moment and upgrade for £49. This will add £10 a month on to your subscription but you could cancel it after a year. 12 £10 + £49 = £169. You could get at least £50 for your Sky + box too.
