when is charlie fairhead coming back to casualty

Charlie Fairhead is reported to be coming back to Casualty as a temporary guest return , but there isn’t a confirmed on-screen date yet. Coverage from late April 2026 says Derek Thompson has already been filming, and the comeback could line up with the show’s 40th anniversary in September 2026.

What’s known

• Charlie was written out in March 2024, not killed off, which left the door open for a return.

• Recent reports say Thompson is filming again, but the BBC has not officially confirmed the storyline details.

• The return is being described as temporary , not a full-time rejoining of the cast.

Timing

• The strongest guess from current reporting is later in 2026 , potentially around the 40th anniversary in September.

• There is no confirmed episode number or exact broadcast date in the reporting I found.

TL;DR

Charlie Fairhead is expected back for a guest return in 2026, but the exact airdate has not been announced yet.
