Short answer: You generally do not need a TV licence to watch Netflix or other on-demand streaming services. A licence is only required if you watch or record live TV or use BBC iPlayer. Details:

• What requires a licence:
  • Watching or recording live TV on any channel or service, including live streams or live broadcasts on the internet.
  • Using BBC iPlayer on any device.
• What does not require a licence:
  • Watching on-demand or streaming content from services like Netflix, Disney+, Prime Video (unless you’re watching live content on those platforms), All 4, or YouTube in non-live mode.
  • Purely on-demand catch-up services that do not broadcast content live.
• Special notes:
  • Some streaming services may carry live content (e.g., live sports); in those cases, a licence can be required if you’re watching that live content.
  • Restrictions or rules can differ by jurisdiction, but in the UK the general rule is as stated above.

If you’d like, I can tailor this to your country and your exact viewing setup (devices, household, and whether you sometimes watch live broadcasts).
