A new adaptation, a UK-German co-production between CBBC, ZDF and Netflix, also titled The Worst Witch, premiered in January 2017 and ran for four seasons, concluding in 2020.

The series stars Georgina Sherrington and Felicity Jones (as Mildred Hubble and Ethel Hallow respectively), and was broadcast from 1998 to 2001 on ITV, and later on HBO.

The series also stars veteran British actress Una Stubbs as the eccentric chanting teacher, Miss Bat.

New recurring characters included Merlin Langstaff, a wizard apprentice who befriended Mildred; his two mean-spirited acquaintances – Barry "Baz" Dragonsbane and Gary "Gaz" Grailquest; Charlie, Frank Blossom's nephew who really wanted to be a witch at first, but then later decided to train to be a wizard; Mrs. Cosie, the nervous owner of the nearby tearoom; and Mistress Hecketty Broomhead, the evil school inspector who later became headmistress for a brief time.

A character who also appears more than once is Egbert Hellibore, chief wizard and headmaster of Camelot Castle, where Merlin, Charlie, Baz and Gaz live.

As common with many other releases of British television programs in the country; the packaging, subtitles and menus are in German, but it contains the original English soundtrack.
