Sanditon Season 3: Everything We Know So Far About the Final Season

Here’s everything we know so far about season 3! Plus, check out the first-look pictures of Charlotte, Georgiana, and Alexander Colbourne.

Sanditon Season 3: First-look photos, Cast, Plot Details, the Romance, & More

MASTERPIECE on PBS dropped three revealing first-look photos for Sanditon Season 3 on Wednesday morning. The pictures from the romantic period drama feature Rose Williams as Charlotte Heywood, Cai Brigden as Ralph Starling, Crystal Clarke as Georgiana Lambe, Edward Davis as Lord Montrose (new character alert!), and Ben Lloyd-Hughes as Alexander Colbourne. 

Sanditon is based on the unfinished novel by Jane Austen and follows the romances and friendships of the young woman Charlotte when she visits the seaside resort town of Sanditon and stays with the Parker family.

Andrew Davies (the legendary British period drama TV writer of productions like Pride and Prejudice) created the series and was the showrunner for season 1. 

After the unfortunate original cancellation (leading to the loss of numerous cast members – including the lead Theo James as love interest Sidney Parker), Justin Young became the header writer for Seasons 2 and 3 when it received a surprise renewal – thanks to devoted fans.

Sanditon is a period drama that knows how to end on massive cliffhangers! In the first season, Sidney ended things with Charlotte to help save his brother’s business despite being in love with her. Only for Sidney to then pass away tragically at the beginning of season 2.

And then, at the end of the second season, Charlotte (despite almost finding love again with the brooding Alexander Colbourne after dealing with a tricky love triangle) announces she has a fiancé: Ralph Starling – a local farmer from her hometown. Much to everyone’s – including the audience’s – surprise.

Meanwhile, her sister Alison Heywood married the dashing Captain Declan Fraser (a Kenneth Branagh lookalike, if ever there was one).

Georgiana Lambe discovered the man she’d been falling for – Charles Lockhart – was after her money; Georgiana also found out her mother was alive, and Clara left her baby to Esther Babbington.

While some characters like Esther received their happy ending, Charlotte and Georgiana still need their much-deserved HEAs.

But could the writers have some more twists and turn in store for their spirited heroines?

For more on Season 2, read our review.

In the first photo, we see Charlotte Heywood looking lovingly up at her fiancé, Ralph Starling. Could Charlotte have real feelings for him? Or is she looking for a comfortable life after too many romantic disappointments and heartbreaks?

Time will tell!

In the second released first-look picture, we meet a new mysterious character – Lord Montrose (played by Edward Davis), as he escorts Georgiana to an event. No details on who this mysterious character is as of yet, unfortunately!

Is he a new love interest for Georgiana? Just a side character meant to throw us off with this photo. Or is another shady character coming after Georgiana’s money?

After two seasons of betrayal, it’s time for Georgiana to meet a good man or proudly choose never to marry! Either way, I’m here for Georgiana Lambe’s happy ending.

Finally, the third photo reveals a melancholic-looking Ben Lloyd-Hughes as Alexander Colbourne.

Is he upset with Charlotte’s betrothal? Will Charlotte end up with Alexander? Ralph? Or someone else like James Stringer (Leo Suter) after a surprise return? Okay, that last one was my own wishful thinking!

But season 3 looks to be promising based on these new photos.


Sanditon season 3 will premiere in 2023 on PBS on MASTERPIECE in the U.S. and on Britbox UK in the U.K. No official release date has been revealed yet.

However, since season 3 finished filming in 2021, the final series should premiere soon.


No official cast details have been announced. Although we do know a few cast members are returning based on the new photos and a few announcements from Sanditon showrunner Justin Young.

  • Rose Williams as Charlotte Heybourne.
  • Crystal Clarke as Georgiana Lambe.
  • Ben Lloyd-Hughes as Alexander Colbourne.
  • Alexander Vlahos as Charles Lockhart.

Yes, that last one may come as a surprise! Justin Young confirmed to Decider that Lockhart will return – “but don’t expect him to make amends to Georgiana.” Yikes! It sounds like the roguish bad boy will remain more of a cad than a redeeming Byronic Hero.

Unfortunately, we also know a couple of cast members will not return for the final season. Tom Weston-Jones, as Colonel Francis Lennox, will not return. Charlotte Spencer, as Esther, will also not be back.

It’s unknown if previous cast members Jack Fox, Kris Marshall, Anne Reid, Lily Sacofsky, Turlough Convery, Rosie Graham, Frank Blake, and Kate Ashfield will return.

New cast members include Cai Brigden as Ralph Starling and Edward Davis as Lord Montrose. PBS should make further cast announcements soon.


According to Crystal Clarke (Georgiana Lambe), Season 3 may be the most exciting. “You’re going to see parties, you’re going to see glam… it’s a highly caffeinated Sanditon.”

Rose Williams (Charlotte Heywood) revealed to MASTERPIECE that Season 3 will also have a lot of characterization. “In Season 3, we see characters meeting with their own unique challenges and really having to dig into deep parts of themselves to find resolve.”

On the other hand, Ben Lloyd-Hughes confirms the story will be full of romance and emotional moments. “I think Season 3 will bring even more excitement, romance, fun, and tears in both forms.”

As for Charlotte and Alexander, their romance will continue to be central to Season 3.

Head writer Justin Young revealed to Decider more details: “The kind of cliffhanger of the season is that Charlotte is now engaged to Ralph…So at the top of Season 3, that’s where we will find her. And that’s the question going into Season 3: She loves Colbourne. He loves her. We know that. But now she’s engaged to Ralph and how is that going to play out?”

It sounds like Season 3 is going to end strong!

An official plot description has yet to be released.


While PBS has only released an official teaser thus far, the one quick sequence reveals a smoldering stare between Charlotte and Alexander – leaving fans’ hearts all aflutter!

Well, that’s everything we know about the show for now. I’ll update this page when PBS releases new details – which I imagine will be very soon.
