List of episodes

The fortieth series of the British medical drama television series Casualty commenced airing in the United Kingdom on BBC One on 2 August 2025. The series focuses on the professional and personal lives of medical and ancillary staff at the emergency department (ED) of the fictional Holby City Hospital. Roxanne Harvey serves as executive producer, while Liza Mellody continued as series producer. Series 40 is expected be the last prior to a new production contract coming into force, and the final to be set in the fictional location of Holby. The series concludes the mini-series Supply and Demand.

Production

Series 40 is primarily filmed at Roath Lock Studios, located in Cardiff, where the serial has been produced since 2011.

The series airs on BBC One. Series 40 will be the final series under BBC Studios' current production contract; production companies were invited to tender for three subsequent years in May 2025. ^[1] BBC Studios is expected to bid to continue as the production company, and Roath Lock Studios will remain as the production base for Casualty. The series' fictional setting, however, will move from Holby for the first time, to a hospital in Wales. ^[2] Actor William Beck who plays Dylan Keogh addressed the change stating "Those parameters we have been given to fulfil are really exciting and I think unprecedented. What we will have on the other side of it is a huge opportunity". ^[3]

The series begins with the fifth episode of the mini-series Supply and Demand, following which the show went on its regular autumn break. It is expected to return in late 2025. ^[4] On 3 October 2025, the next mini-series titled Learning Curve was announced and will introduce two new junior doctors to the cast. ^[5]
