Guest stars have been announced for the upcoming third series of Stath Lets Flats.

With filming having just completed, the Channel 4 sitcom's next run will feature appearances from Julia Davis, Charlie Cooper and David Avery.

The channel and producers Roughcut say: "The third series will pick up where the second finished with a shocking cliff-hanger as incompetent letting agent Stath is faced with rescuing the family business, Michael & Eagle, and his relationship with Katia, while expecting his first child by Carole. Meanwhile his sister, Sophie, and best friend, Al, deal with the fallout of finally declaring their feelings for each other."

They tease: "Series 3 will feature some stellar guest stars, including Julia Davis who appears in one episode as Kris, Carole's belittling and snobbish sister; David Avery plays Bambos, Stath's flash barber cousin ...and Charlie Cooper plays Gregory - a lettings agent who is passionately devoted to his wife and runs a rival agency called Live Love Lets."

Created and written by Jamie Demetriou, who plays the titular role, the returning regular cast includes his real-life sister Natasia Demetriou as on-screen sister Sophie; Christos Stergioglou as their dad; Katy Wix as Carole; Ellie White as Katia; Al Roberts as Al; and Kiell Smith-Bynoe as colleague Dean.

To air later this year on Channel 4, Series 3 will also see the return of guest stars Nick Mohammed, David Mumeni and Tom Stourton.

Jamie Demetriou said today: "Times are the worst they have been in living memory, but fear not, a sitcom about a lettings agency is back for a third series! All the characters (bar a few who had availability issues) are back and saying stuff aaaall over again! Get ready to hear what they say! Listen closely and you might even hear a thing or 2 from some new celebrated guest stars. Did somebody say.... the whole England football team?? No, it'll be comedy actors!"

Ash Atalla, Managing Director of Roughcut Television, adds: "We're so happy to bring Stath back and welcome the new cast. The audition process was 9 months of actually letting flats so we have high hopes for the new series."
