If you know a site that streams original content which UK viewers can watch for free, post a link.
Here's a couple to start
https://www.channel4.com/ - currently the best TV site in the UK
https://www.bbc.co.uk/iplayer - make sure you've got a licence?
https://www.itv.com/ - a great site with lots of content, but it depends too much on older content
https://www.channel5.com/ - good site, but I'd like to see *more* of their older content
https://www.rte.ie/player/ - Ireland's national broadcaster. Not all shows are available in the UK, but some are
https://watch.blaze.tv/series - mainly alien/mystery shows, along with Pawn Stars/Storage Hunters type stuff. (720p)
https://www.watchfreeuk.co.uk/page/series - mostly crime docs, but also the random drama series thrown in. (1080p)
https://www.watchfreeuk.co.uk/page/movies - the same site, but their b-movie section. Loads of stuff to rummage through.
https://u.co.uk/ - UKTV's updated branding. Drama, comedy, docs (including a load of Guy Martin's shows)
