You can watch the main Jay Slater documentary on a couple of different platforms, depending on which one you mean by name and by country (most of the coverage so far is UK‑based). Below are the key options people are talking about right now.

1. Channel 4 / Apple TV documentary

The best‑known full‑length TV documentary is “The Disappearance of Jay Slater” (2025) , a UK TV special that follows his family and the online speculation around the case.

  • In the UK, it is listed under the title “The Disappearance of Jay Slater”.
  • It is available to stream via Apple TV in the UK region (Apple TV app / website, UK store).
  • It is also a Channel 4 production , so it may appear (or have appeared) on Channel 4’s own platforms (e.g., in the UK on their streaming service) around the original broadcast window.

If you are outside the UK, availability can differ: sometimes it does not show in local catalogues or may appear under regional licensing; using the Apple TV app and searching the exact title is the most reliable check.

2. ITV News special (short documentary)

There is also an ITV News special called “Missing in Tenerife: The search for Jay Slater” , which is a news‑style documentary about his disappearance rather than a full true‑crime series.

  • It is available to watch via ITV’s own website / ITV News video section under that title.
  • This is more of a long news report / special rather than a feature documentary, but many viewers refer to it as a “Jay Slater documentary” too.

3. YouTube podcasts and breakdowns

If you are open to more informal or commentary‑style “documentary” content:

  • “Jay Slater: Murdered? The Mysterious Disappearance” – a longform true‑crime podcast episode on YouTube from I Could Murder A Podcast , discussing his final movements, search efforts, and online theories.
  • Various creators also post episode breakdowns and reactions to the official documentary, often titled along the lines of “Jay Slater documentary – my thoughts / final video,” which summarize or critique what was shown on TV.

These aren’t official TV documentaries, but they function as detailed case deep‑dives and are easy to watch worldwide on YouTube.

4. How to quickly find it

To locate the exact documentary in your region:

  1. Open Apple TV (or your device’s Apple TV app) and search for “The Disappearance of Jay Slater”.
  1. If you are in the UK, also try your Channel 4 streaming app/site around the documentary’s 2025 air date.
  1. For the ITV special, go to ITV’s website and search “Missing in Tenerife: The search for Jay Slater” in the news/video section.
  1. On YouTube , search “Jay Slater documentary” or the specific titles above for free commentary‑style content.
