No release date has yet been announced for the new series, however, it is expected to premiere in the winter of 2023. The series will consist of eight episodes.

Belgravia: The Next Chapter picks up in 1871, three decades after the events of the original 2020 limited series. The limited series was written by Julian Fellowes, the man behind Downton Abbey and The Gilded Age. Belgravia: The Next Chapter was developed and written by playwright and screenwriter Helen Edmundson.

The series will tell a love story, centering on Frederick Trenchard, the third Lord Trenchard, and his love interest Clara Dunn, who is new to the often abrasive world of London high society. Having grown up in the upper ranks of society, Frederick is unaware that his birth is the product of an affair between his mother, Susan, and the rake, John Bellasis. Having endured a troubled childhood, Frederick has been left deeply insecure, which proves to be a challenge in his evolving relationship with Clara. The series also dives into the intriguing and chaotic world of Belgravia, a London neighborhood known for its ultra-wealthy residents.
