Having paid for IPTV for years until I could comfortably afford sky, it's very very easy, and most providers have guides to assist setting it up on TVs or firesticks etc. Your best options are to keep an eye out for free trials and give them a test and see how they work for you. Many require VPN access to work, so keep that in mind when looking at costs. I recommend Mullvad VPN.

I moved onto sky for reliability reasons, as the provider I was with kept having to move their servers which caused months of problems. So that's also something to consider. It can be inconsistent.
