Blue Planet III airs Sunday, November 1 at 8pm BST on BBC One and BBC iPlayer in the UK.
The six-episode series — filmed over four years and scored by Hans Zimmer, will roll out weekly on BBC One every Sunday until December 6. The first three episodes are available now on BBC iPlayer for free. The remaining three arrive one week later.
Where to watch
| Country | Channel or service | Free or paid |
|---|
| UK | BBC One, BBC iPlayer | Free (requires UK postcode and valid TV licence) |
| US | BBC America, AMC+ | Paid |
| Canada | BBC Select, AMC+ (some viewers) | Paid |
| Australia | Channel 9, 9Now | Free (launching in early 2027) |
Free options are limited to the UK for now. BBC iPlayer offers all six episodes at no cost to users with a UK postcode and a valid TV licence. No subscription or paywall applies, just those two requirements.
What to expect from the event: Blue Planet III is not a live broadcast in the sense of a sports match or awards show. It’s a linear TV premiere and on-demand release of a pre-recorded natural history documentary series. Viewers will see Sir David Attenborough, now in his centennial year, narrating newly captured underwater footage across tropical seas, the open ocean, polar waters, and future-facing marine science. Each episode runs one hour.
Outside the UK, access is delayed and platform-dependent. In the United States, BBC America and AMC+ will carry the series starting January 23, 2027. Canadian viewers must wait for BBC Select’s 2027 rollout, though some may access it earlier via AMC+. In Australia, Channel 9 and its streaming platform 9Now will host the series in early 2027.
No global simultaneous launch is planned. The UK remains the sole market with immediate, free access, and only under the terms set by the BBC’s licensing regime.
The series marks the third installment in the landmark Blue Planet franchise, following the original (2001) and Blue Planet II (2017). Attenborough noted in the sources that he did not anticipate narrating a third series in his 100th year, underscoring both the longevity of the project and the urgency of its subject matter.
No official streaming partnerships or free alternatives have been announced for India, Germany, France, or other major markets beyond those listed. Nor has the BBC confirmed plans for a standalone app, international iPlayer rollout, or YouTube release.
Viewers outside the UK should check local broadcaster schedules as 2027 approaches, and note that regional availability remains tied to existing distribution agreements, not on-demand demand.
