Darren Boyd took home 'Best Comedy Actor' for Spy, while Victoria Wood won 'Best Female Television Comic' for her Angina Monologues. Both shows are broadcast on Sky 1.
Boyd said Sky executives were "really nurturing shows and scripts that they believe in". A second series of Spy has now been commissioned.
The broadcaster had a total of five nominations, with An Idiot Abroad and Sky Atlantic's This Is Jinsy also up for gongs.
Armando Iannucci, winner of the 'Writers' Guild of Great Britain Award', said that "there were no pre-conditions' for taking Alan Partridge to Sky Atlantic".
He continued: "I've done stuff with Sky News, Sky Arts is fantastic and Sky Atlantic is great. For years people have been having a go at them for making all this money and not putting it into home-grown, home-based production. Now they're doing that the last thing we want to be doing is have a go at them."
Iannucci added that the team had "just finished shooting some Alan" this week.
