IPTV vs OTT vs FAST: What Is the Difference? (UK Guide)
⚡ Quick Answer
IPTV, OTT and FAST are three ways of getting TV over the internet. Here is what each one means, how they differ, and which suits UK viewers.
The short version
- IPTV — live TV channels with a programme guide, delivered over the internet. Usually a paid subscription.
- OTT ("over the top") — streaming apps such as Netflix, Disney+ and NOW, mostly on demand.
- FAST (free ad-supported streaming TV) — free channels funded by adverts, such as those in Samsung TV Plus or Pluto TV.
IPTV
IPTV gives you traditional channels — BBC, ITV, sports channels — that you flick between with a TV guide, plus catch-up and often an on-demand library. It feels like Sky or Freeview, but arrives over broadband. What is IPTV? explains it in more depth.
OTT
OTT apps are mostly on demand: you choose a film or series and press play. Some offer a little live content, but they rarely replace live TV and sport.
FAST
FAST channels are free and run like regular TV channels with adverts, but they are mostly repeats and niche channels rather than major live sport or first-run UK TV.
