Did a similar thing a couple of years ago - ditched Sky and went full digital. Difference was we were using a chromecast instead. Which is fine, you can watch what you want, but (a) it's more convoluted to fire up the app on your phone then wait for the cast button to appear (and potentially reboot the chromecast as has been happening more recently), and (b) a lot of the terrestrial channel streaming services (NowTV is an exception) don't allow you to cast live channels - only on demand. Got a 4K apple TV the other week which solves both of the above and wondering why I didn't do it earlier!
