Is there a Grantchester series 11?
Well, there’s good news and bad news for fans. ITV has now confirmed that crime drama Grantchester will be returning for a series 11. However, the news is bittersweet as it will also be the last series.
Writer, series creator and executive producer, Daisy said: “At its heart, Grantchester is a show about the power of friendship and love. We’ve been so lucky over the last 11 series to experience that on and off screen. For over a decade now – cast and crew (many who’ve been there since the beginning) have met each summer to film. And it’s been an absolute joy.
“Thank you to James Runcie for entrusting us with his characters, and to the lovely people of real Grantchester. Thank you to everyone who’s been a part of the show in any way – big or small. I’ll miss you terribly.”
What is the plot?
Grantchester series 11 joins Geordie and Alphy in the heady Summer of ’63. Alphy is learning more about his past. He comes to realise that there is a whole other life he could have led, making him question who he is and what he believes in. He’s also continuing to get to know Meg, the Bishop’s daughter…
A synopsis continues: “Geordie, for once, is positively brimming with bonhomie! He’s learned to weather the storms of life and is enjoying a time of relative peace. Cathy’s happy now that CeCe’s Fashion Boutique is a success, and the kids are old enough to look after themselves!
“But then, out of the blue, the Chief Superintendent comes to Geordie with a beguiling offer. It could be a chance for Geordie to finally be in charge, but it could also mean an end of his crime solving days. And his crime solving partnership with Alphy… ”
Meanwhile, Leonard finds himself with time on his hands during a quiet period at the halfway house. He takes the opportunity to take stock of his own life and whether he’s doing enough with it. When one of Daniel’s neighbours becomes ill, Leonard is drawn into helping care for the neighbour’s son Raymond – and discovers a paternal side to himself he never knew he had.”
The synopsis concludes: “In Grantchester series 11 everyone will question the paths they are on, and some huge decisions will be made. This season will look at family, forgiveness, identity, and faith. Big changes are coming to Grantchester…”

When’s the start date? How can I watch it?
Grantchester series 11 is expected to air on ITV, STV, ITVX AND STV Player in 2027. It has just started filming in the UK (July 2025). Series 10 will land on our screens first. It’s ready to go, having been filmed in 2024 – and should land in early 2026.
The detective show typically starts in January, and runs for six or eight weeks, depending on the number of episodes. While most series are six instalments, series 6 and series 9 were both eight parts in total.
All previous series are currently available to watch on ITVX.
Why is Grantchester ending?
In July 2025, ITV confirmed that Grantchester series 11 will be the final series as it comes to an end after 11 years. Although they did not explain why.
Despite its continued success, ITV has made the decision to end the series. Just last year, Masterpiece executive producer Susanne Simpson said: “This is hands down one of our most popular series, and I know the fans will be thrilled to see it continue with the outstanding Robson Green and Rishi Nair back for more crime solving in series 10.”
Meanwhile, leading man Robson Green, who has played DI Geordie Keating since series 1 in 2014, has previously made it clear he had no plans to leave the show.
When asked if he ever gets tempted to leave the show, like co-stars James Norton and Tom Brittney, Robson made it clear he was happy to stay.
Robson, who is also executive producer of Grantchester, explained: “I never get itchy feet because I’m at a stage in my life where I want to work with people who make me genuinely happy, in front of the lens and behind it.
“I’m not chasing awards, I’m not chasing fame. I’m just being present in a very enjoyable and healthy environment, and that’s what Grantchester is. It’s one of the nicest jobs I have ever done in my career.”
In an interview with TVGuide.co.uk, he added: “I’m very blessed that I can do other stuff. I do documentaries and I do other dramas. Why would I want to leave? I never take one second of Grantchester for granted.”
Of course, Robson’s fans will know he recently starred in the gripping Channel 5 thriller The Game.

Talking about the cast, Director of Drama at ITV Polly Hill said: “It’s rare to create a series with such enduring warmth, wit, and heart. No one could have played Geordie quite like Robson. And, alongside Rishi, Al, Tessa, Kacey, and the rest of this wonderful cast and crew, they’ve built something beloved and beautiful.
“This final series marks the end of a golden chapter for ITV drama. We know audiences will treasure this last summer in Grantchester as much as we will.”
Why is Robson Green leaving the detective drama?
Talking about Grantchester coming to an end, Robson Green, said: “From the very beginning, I have had the incredible fortune to be part of this extraordinary team of talented, passionate, and dedicated individuals who have become more than colleagues. They have become family.
“I have made friendships forged through shared laughter, challenges, and triumphs. The bonds we’ve formed extend far beyond the camera lens, and I know that they will endure long after the final scene within the Grantchester world has been filmed.”
He added: “Thank you to everyone who has been part of this incredible journey. […] It has been an honour to share in the magic of Grantchester, and I am forever grateful for the memories, the friendships, and the love that this journey has given me. I hope I made you proud.”

Over two seasons – and now as we begin filming our third – I’ve had the privilege of telling stories that mean so much to so many. I’m deeply thankful for that.
“As we begin filming this final chapter, I do so with a full heart and endless gratitude – for the memories, the friendships, and the incredible journey we’ve shared. To the entire cast and crew – thank you for your unwavering support, love, and warmth that you all bring onto set every day. Working alongside you all, and more importantly getting to know you, has been a true privilege and joy.”
