In January of 2019, Channel 4 announced that Stath Lets Flats had been recommissioned (greenlit) for a second series. Stath Lets Flats began broadcasting on Augon its home channel of British's very own Channel 4.

The second series also received a nomination in the Best Scripted Comedy category at the 2020 British Academy Television Awards, while Jamie Demetriou was again nominated for Best Male Comedy Performance and was also nominated in the Best Writer: Comedy category at the 2020 British Academy Television Craft Awards. It was nominated for Best Scripted Comedy at the 2019 British Academy Television Awards, with Jamie Demetriou also nominated for Best Male Comedy Performance. Elisa Bray of The i said that it 'roared along at speed with energy and absurdity'. Guy Pewsey of The Evening Standard said that it contained 'moments of classic, unmistakably British, humour'.

Sam Wollaston of The Guardian gave it a positive review saying that there was 'plenty to like'. The critical reception for Series 1 was generally positive. “This is one-note comedy - hilarious if you enjoy the sight of implausibly stupid people embarrassing themselves endlessly.Stath Lets Flats stars Demetriou as a stupid, incompetent, socially inept Greek-Cypriot letting agent in London who only has his job because his father is the owner and manager of the company. Its characters may be idiots (every single one of them, no exceptions), but they’re well-meaning, expertly performed and treated with warmth by Demetriou’s script – even when speaking absolute rubbish.” “It’s silly, ludicrous and nonsensical – but a preference for word play and slapstick doesn’t mean the show lacks heart. Not a thinly fictionalised semi-autobiographical warts-and-all think-piece. Not a first-person confessional diatribe. “Stath Lets Flats trounces the competition by the sheer fact that it has the guts to be a comedy. Whether it’s because his English is sketchy or simply because he is just dim, Stath - the delightfully upbeat Greek-London letting agent played by Jamie Demetriou - still can’t finish a sentence without mangling words at such a pace that you may need to rewind to catch what he’s burbling about.” “It elevates half-wittedness to something approaching an art form.
