Following the news BBC One medical drama Casualty has been put out to tendering, a huge change for the structure of the show has been revealed.

The competitive tender process will decide which producer makes the show, though the BBC will retain all the rights for the programme.

Casualty will also continue to air on BBC One.

While this development won’t impact the future of the medical drama, it will change the foundations of the series. Casualty is set in the Emergency Department of Holby City Hospital, but this won’t be the case once the new production company take over.

It means the ED will be set in Wales, rather than the fictional city of Holby.

In an official document from the broadcaster, there is hope the show will ‘evolve into Welsh portrayal while maintaining the core attraction to the loyal fan base’.

The contract asks tenderers to include ‘authentic representation of Wales and reflect the reality of the Welsh NHS’.

‘This is not about radical change of the show, although the move to Welsh portrayal will mean a new fictional hospital based in Wales, and tenderers will need to address this core change in their editorial pitch to the evaluation panel.

‘The successful tenderer will need to be able to demonstrate how to incorporate Welsh portrayal and maintain familiarity at the same time.’
