Behind the scenes, locations and more about After The Flood

Filming started on After The Flood in February 2023 in the Manchester, Derbyshire, West Yorkshire and Teeside areas of the UK.

After the Flood is produced by multi-award-winning Manchester-based executive producer Nicola Shindler and her team, including fellow exec producer Richard Fee,  at Quay Street Productions in association with ITV Studios. The drama is written by Mick Ford.

Nicola Shindler and Richard Fee, executive producers have said: “When Mick Ford brought the kernel of the idea of After the Flood to us, we were immediately drawn in. Not just by the catastrophic repercussions of a deadly environmental disaster in a town that could very well be our own, but also the intricacies and deception at the heart of the characters’ stories. 

"We have a brilliant combination of writing, directing and acting talent on board to bring this series to life and we’re looking forward to working with our partners at ITV and BritBox International as we begin filming.”

Mick Ford adds: “I'm always excited to announce a new project but After the Flood in particular tops all of the others due to its ambition and the characters. The cast are fantastic, and I am thrilled with how perfect each cast member is for their role. 

"ITV has been brilliant throughout the writing process allowing us the time to craft the scripts with care which is rare and brilliant. Plus working with Quay Street Productions for Nicola and Richard is so special – because they and their teams are so special, and I feel truly honored. It is going to be great seeing everyone getting into the story and seeing it come to life — and then there is the flood!”

Reemah Sakaan, CEO BritBox International said: “After the Flood is a gripping thriller featuring a fantastic cast, led by Sophie Rundle as our determined investigator, getting stuck into a complex crime in her community, with environmental catastrophe as a backdrop. We are incredibly proud to be working in partnership with ITV and Nicola’s team at Quay Street on this production. The series joins our world-class slate of quality British originals and its themes are sure to resonate with fans around the world.”
