Production

The series began airing in the United Kingdom on 10 August 2024 on BBC One, a week after the conclusion to the previous series. Series 39 is set to continue following a three month break in late 2024. At the end of the Storm Damage miniseries, a trailer for the Christmas special was shown. A subsequent press release stated that "the Christmas special will celebrate the gift of giving and will be told in an innovative, format-breaking way". In November it was confirmed that the episode would revolve around "the miracle of blood" and incorporate real-life testimonies. The subsequent miniseries, entitled Public Property, commenced the week after the Christmas special and consisted of eleven episodes. On 30 January 2025, the following miniseries was announced to be titled Internal Affairs, set to consist of twelve episodes. The most recent miniseries Supply and Demand was announced on 10 June 2025, again consisting of twelve episodes.
Roxanne Harvey was announced as the series' new executive producer in November 2023, taking over from Jon Sen. Harvey looked forward to creating "distinctive, addictive characters alongside ambitious, emotionally epic stories that reflect our modern day NHS". Harvey assumes the role from the Christmas special; no executive producer is credited throughout Storm Damage.
The show introduced an updated version of the title sequence introduced in series 33, starting with the first episode of Internal Affairs. The sequence was truncated to show writer, producer and director credits with the mini-series title below the Casualty logo. The font displaying the cast names in the closing titles were changed to bold. It also marked the show’s return to omitting on-screen episode titles for the first time since series 35.
Episodes from Supply and Demand are untitled with episodes 5 to 12 being the first eight episodes of series 40.

Cast

The thirty-ninth series of Casualty features a cast of characters working for the NHS within the emergency department of Holby City Hospital and the Holby Ambulance Service. Sixteen cast members reprised their roles from the previous series, with this series the first not to feature Derek Thompson as Charlie Fairhead.
Manpreet Bachu stars as junior doctor Tariq Hussein, William Beck appears as Dylan Keogh, a consultant in emergency medicine and Di Botcher portrays Jan Jenning, the operational duty manager at Holby Ambulance Service. Anna Chell plays staff nurse and midwife Jodie Whyte and Milo Clarke plays paramedic Theodore "Teddy" Gowan. Sammy T. Dobson continues as junior doctor Nicole Piper with Melanie Hill portraying clinical nurse manager Siobhan McKenzie. Elinor Lawless stars as consultant Stevie Nash with Kirsty Mitchell portraying Faith Cadogan, an advanced clinical practitioner. Neet Mohan appears as Rash Masum, a clinical fellow whilst Adesuwa Oni continues as staff nurse Ngozi Okoye. Sarah Seggari and Kellie Shirley play staff nurse Rida Amaan and psychiatric liaison nurse Sophia Peters. Michael Stevenson and Charles Venn feature as paramedics Iain Dean and Jacob Masters respectively. Barney Walsh plays staff nurse Cameron Mickelthwaite.
The first episode of Public Property introduces Naomi Wakszlak as trainee paramedic Indie Jankowski. Prior to the third episode of the miniseries it was confirmed that Wakszlak had joined the cast in a regular capacity, with Indie pursuing her third-year placement at Holby. The character is Casualty's first student paramedic. Harvey commented that "Naomi is an emerging talent who brings depth and authenticity to the role, seamlessly capturing Indie’s determination and drive to prove herself in a demanding environment."
From Internal Affairs, Olly Rix joined the cast as Flynn Byron, a former military doctor and clinical lead. Robert Bathurst also appeared as surgeon Russell Whitelaw. Russell is described as "a man who has commanded the operating room for years with his unmatched skill and domineering personality".
Shirley departed in episode 15, the Public Property episode "Brace, Brace, Brace", stating that portraying a storyline involving pregnancy termination was emotionally challenging. Bachu leaves the series in episode 19, the Internal Affairs episode "Civil War."
