Check the UK programmes you would miss
Start with the programmes that make your current TV package useful. Check the specific titles and viewing location before assuming another service covers the same evening.

Use the current listings for your area
Record the broadcaster, programme and time. Check whether you need the live version, a regional edition or a replay. If your household watches a local news bulletin, include the region when you ask.
Try the controls you use every day
Search for one programme, turn subtitles on and reopen the app after switching inputs. Confirm any programme the trial cannot cover before paying for a longer term.
