Had a Kodi box for about a year now, up to date films, all Sky channels incl sports, all BT sports channels plus the usual ones here that you have on Sky plus many overseas channels. All you need is a decent wifi speed , and a VPN ( check Google) so for an initial cost of say £100 then £40 a year for a VPN that's the outlay. No problems with signal when weather bad. This system is big in the USA and Canada where they have been using it for about three years now, keep Sky go on basic only and give Kodi a try, you will not be disappointed.if not happy then back to Sky you go. I have stopped all Sky premium channels and just use Kodi, saved £50 per month.
