The new season of Shetland is currently being filmed, and the BBC says the six-part series is in production “over the coming months,” so the exact release date has not been announced yet.

What’s known

  • Filming for the next series began in April 2026.
  • The BBC has confirmed it will be a six-part season.
  • Coverage from April 2026 suggests the show is still in production, which usually means a release is still months away.

Best estimate

  • Based on the current filming timeline, a late 2026 debut looks most likely, but that is still an estimate rather than an official date.
  • Nothing in the reports I found gives a confirmed premiere day yet.

Where it will air

  • Past and current coverage points to BBC One and BBC iPlayer as the home for the series.

TL;DR: no official air date yet, but the new season is in filming now and a late-2026 release is the most plausible expectation.
