Yes, every episode has edits - most notably to Richard O'Brien's closing monologue which has been edited out ever since Challenge began airing them.

When series 2 was repeated on Channel 4 back in the day, I remember the usual longer theme tune ending was edited to a much shorter version with 2 columns of credits. Richard O'Brien's closing remarks were often cut short to a quick overhead view of the dome, "Force Field" abruptly starting halfway through the theme, followed by a sharp fade to the edited credits. This unusual Series 2 editing by Channel 4 is still shown by Challenge to this day.

Series 1 monologues are generally cut short but with the full extended theme. Indeed, tonight's episode ran with ads to 59 minutes long, so Challenge did not have time to show any ads after it and went straight to Weakest Link. I think Series 3 onward doesnt have trimmed ROB's or Ed's closing comments by Challenge. Ed's Series 5-6 episodes are edited at unusual unexpected points during the show for extra ads but it's not a massive issue.
