Series 31

Series 31 will be the thirty-first series of Casualty and will commence airing in 2016. The current series producer Erika Hossington revealed that they have big plans for the show's thirtieth anniversary, which will fall at the beginning of this series in September 2016. She also revealed in an interview that the premiere of series 30 featuring Charlie having a heart attack sets up for the first two episodes of series 31 they have planned.

When asked about the cast, Hossington stated that viewers can expect to see a few new faces later in the year (2016), which will likely be in series 31. In February 2016, Oliver Kent posted a picture on Twitter of the front pages of the scripts of the first and second episodes of series 31, which were also labelled as the 30th anniversary special parts one and two, respectively.

In terms of cast changes from series 30, it's going to be one of the most dramatic jumps yet. Three brand new cast members will have already joined from series 30, setting them up for series 31. These are a paramedic, nurse and consultant. The paramedic (Jez Andrews) replaced Dixie, and the nurse (David Hide) will replace Lofty. Elle Gardner will be a replacement for Zoe, but it's likely Zoe's departure will take place a while after Elle's arrival in May. In March 2016 through a picture posted on Twitter by William Beck, Zoe's departure was confirmed as she wasn't seen on the section of the staff hierarchy grid shown. Also in the picture, Elle is shown at the top with "Clinical Lead" written under her name, proving she will replace Connie in that role. Connie and Dylan were seen below her in the hierarchy and will be working as regular consultants. The only other character seen in the photo is Ethan, therefore confirming their presence on the show until late 2016.
