Hi pete37593
You can add the normal Sky Cinema channels, but if you also want the Sky Movies in UHD then you also need the Sky Cinema and Sky Entertainment UHD add on which is an additional £6 a month for customers with Mega TV packages (Bigger Combo/Biggest Combo/Mega Volt), Maxit TV packages (Fullhouse/ Bigger Bundle/ Ultimate Oomph/ Ultimate Volt)
You won't receive the actual Sky Cinema channels in UHD, instead there is large selection of Sky UHD movies (currently 488) available via On Demand, along with a number of normal Sky programs/box sets in UHD (currently 119).
The Virgin Ultra HD channel on 175 and 999 is free to all customers with a compatable box (V6, TV360 and Stream boxes)
There are 4 Sky Sports UHD channels, which are Sky Sports Main Event UHD, Sky Sports Darts UHD (this is a temporary channel and will revert back to Sky Sports F1 UHD sometime around 19th January) along with Sky Sports UHD 1 and 2 which provide additional UHD content when available. You do need to have a Sky Sports HD subscription before being to add the Sky Sports UHD channels which are either an extra £6 or £7 a month.
You may be able to get a discount if adding both Both Sky Sports UHD and Sky Cinema and Sky Entertainment UHD
You can also take out a subscription to TNT Sports which contains all 4 TNT Sports channels, including TNT Sports Ultimate.
