The sitcom's return had been revealed in March, but now the six-episode order has been officially confirmed by the corporation.
Talking about the new series, producers tease: "A collective sigh of relief can be heard across the Motherland as a new school term dawns. It's also dawned on Julia that she still hasn't sorted her childcare. Her wonderful husband has decided to step up to the mark and train for Iron Man.
"The alpha mums are back in the cafe, rolling up their blouse sleeves for this year's PTA while Kevin looks on from his table next to the toilet. Liz has mastered the art of not giving a f**k, and is going back to bed."
Head of comedy commissioning, Shane Allen said today: "The last few years in BBC Comedy have been a boom time for new talent with multi-award winning shows including Fleabag, This Country, The Young Offenders and People Just Do Nothing. These are shows that have taken a risk on new talent, which have resulted in comedy from the heart that has a very real sense of place and with characters you grow to care about - who earn those emotional twists and turns."
