Posy Sterling is a British actress whose career has grown from theatre and community-based performance into acclaimed film and television work. She became particularly well known for playing Molly Brown in Lollipop, a performance that won her a British Independent Film Award for Breakthrough Performance and led to a nomination for the 2026 EE BAFTA Rising Star Award.
Her career, however, did not begin with a sudden screen breakthrough. Sterling spent years developing her craft through drama training, Clean Break productions and major theatre work before gaining wider recognition through projects including The Outrun, World on Fire, Playing Nice, Dirty Business and Trigger Point.
That combination of stage experience and increasingly prominent screen roles makes her one of the notable emerging British performers of the mid-2020s.

Who Is Posy Sterling?
Posy Sterling is an English stage, film and television performer who built much of her early career in theatre before moving into larger screen projects.
Although Lollipop introduced her to a much broader audience, her development as an actor stretches back considerably further. Clean Break records show that she joined its young women’s programme in 2015 before drama school and later returned to work on several of the company’s productions.
Sterling was also selected as one of Screen International’s Stars of Tomorrow in 2023, an industry programme that highlights emerging UK and Irish talent. BAFTA later referenced that recognition when announcing her as one of its five Rising Star nominees for 2026.
Her work has frequently connected with stories involving family, justice, social pressure and people navigating difficult institutions.
Early Life and Acting Training
Sterling was born in Manchester in 1992. She spent parts of her childhood in north London before living in Market Harborough, Leicestershire, which she has described in interviews as an important part of her upbringing.
Performing became an interest while she was young. Local reporting has connected her early development with drama opportunities around Market Harborough, before professional training became the next stage of her career.
She later trained in acting at Italia Conti. Her relationship with Clean Break was also significant. The theatre company says she joined its programme in 2015 and subsequently appeared in projects including Belong and Sweatbox.
Sterling’s creative background was not limited entirely to acting. Clean Break’s professional biography also describes her as an actor and singer and notes her involvement with an Amy Winehouse Foundation music project.
Building a Career Through Theatre
Before her best-known film roles, Sterling developed substantial experience on stage.
She appeared in Sweatbox, Chloë Moss’s drama staged by Clean Break, and took part in Belong. These projects helped establish a connection with a company known for creating theatre involving women affected by, or at risk of involvement with, the criminal justice system.
A major theatre credit followed with Deborah Bruce’s Dixon and Daughters. The production was a collaboration between the National Theatre and Clean Break and ran at the National Theatre’s Dorfman Theatre in 2023. Sterling played Leigh alongside a cast including Bríd Brennan, Andrea Lowe and Liz White.
She later appeared in Benedict Andrews’ production of The Cherry Orchard at London’s Donmar Warehouse. The production subsequently transferred to St. Ann’s Warehouse in New York, where Sterling spent seven weeks performing.
That stage background is important to understanding her career. Her screen recognition arrived relatively recently, but it was built on years of live performance and ensemble work.
Posy Sterling in Lollipop
The most important screen role in Sterling’s career so far is Molly Brown in writer-director Daisy-May Hudson’s Lollipop.
The film follows a mother leaving prison who hopes to regain custody of her children but becomes caught in a housing and care-system dilemma: she needs suitable accommodation to get her children back, yet her housing situation is affected by the fact that they are not currently living with her.
For Sterling, it was her first leading feature-film role.
Preparing for Molly involved more than learning a script. Sterling has discussed researching women’s experiences and speaking with people with lived experience in an effort to approach the character carefully and authentically.
The performance became the turning point in her public profile.
At the 2025 British Independent Film Awards, Sterling won the Breakthrough Performance award for Lollipop. BAFTA subsequently selected her for the 2026 EE Rising Star shortlist alongside Archie Madekwe, Chase Infiniti, Miles Caton and Robert Aramayo.
Robert Aramayo ultimately won the public-voted BAFTA category, meaning Sterling was a nominee rather than the 2026 Rising Star winner.
That distinction matters because some online summaries can blur the difference between receiving a nomination and winning the award.
Movies and TV Shows Before and After Lollipop
Sterling’s filmography is broader than Lollipop.
The Outrun
She appeared as Rehab Rita in The Outrun, the drama starring Saoirse Ronan. Sterling has said that working with Ronan was a valuable learning experience ahead of taking on her own leading film role.
World on Fire
Sterling appeared as Eileen in the BBC historical drama World on Fire. The credit helped expand her screen work while she continued building her theatre career.
Person of Interest
She played Alice Khan opposite Asim Chaudhry in Person of Interest, written and directed by Aysha Rafaele.
Playing Nice
Sterling also appeared as Kiera Keenan in the television thriller Playing Nice, alongside James Norton, Niamh Algar, James McArdle and Jessica Brown Findlay.
Together, these roles show a gradual transition from theatre into a varied screen career rather than an overnight rise.
Posy Sterling in Dirty Business
In 2026, Sterling took on a fact-based role in Channel 4’s three-part drama Dirty Business.
The programme examines allegations and investigations surrounding sewage pollution and English water companies. Sterling portrayed Julie Preen as part of a storyline concerning the Preen family and the death of their eight-year-old daughter Heather following an E. coli infection.
The series also featured David Thewlis, Jason Watkins, Asim Chaudhry and Tom McKay and aired across three consecutive nights beginning on 23 February 2026.
The role continued a pattern visible in Sterling’s work: participation in dramas built around serious social or institutional issues.
Posy Sterling in Trigger Point
Another major 2026 credit is the fourth series of ITV’s Trigger Point.
Sterling plays DC Ellie Hackett in the crime thriller led by Vicky McClure as explosives officer Lana Washington. Her credited appearances span the six-episode fourth series.
ITV released series four in late August 2026. The broadcaster reported that the show became ITVX’s most-watched series of that August after only two days on the platform.
For Sterling, the role placed her in a well-established mainstream ITV drama shortly after the awards attention generated by Lollipop.
Screen School and Work With Young People
Sterling has also worked to create opportunities for younger performers.
Clean Break’s biography for Dixon and Daughters identified her as the founder and director of Screen School, an initiative working with young people in the East Midlands.
She has explained that the workshops were designed to provide young people with space to express themselves, build confidence and explore screen-related creative work.
This part of her career reflects a connection between her own route into performance and her interest in making creative opportunities accessible to others.
Awards and Growing Recognition
Three milestones stand out in Sterling’s rise.
Screen International named her a Star of Tomorrow in 2023. Her performance in Lollipop then earned the 2025 BIFA Breakthrough Performance award. In January 2026, BAFTA announced her as an EE Rising Star nominee.
The progression is notable: industry recognition first identified her as emerging talent, followed by an award for a specific performance and then wider national attention through BAFTA.
By 2026, her credits ranged from independent film and National Theatre productions to Channel 4 factual drama and a mainstream ITV thriller.
What Is Known About Posy Sterling’s Personal Life?
Public interviews contain some information about Sterling’s childhood, siblings and the places where she grew up, but reliable professional sources remain focused mainly on her acting and creative work.
There is no need to fill those gaps with assumptions. Claims about a husband, partner, marriage or other private relationships should not be presented as fact unless Sterling or a dependable source publicly confirms them.
For readers researching her career, the best-documented story is currently her journey from theatre training and Clean Break to Lollipop, major awards recognition and increasingly prominent television work.
Why Posy Sterling’s Career Is Getting More Attention
Sterling’s recent rise is not based on a single credit.
Her career combines theatre training, socially focused work, supporting screen performances and a critically noticed first leading film role. Lollipop supplied the major breakthrough, while Dirty Business and Trigger Point demonstrated that her screen career was continuing to broaden during 2026.
Her BIFA win and BAFTA Rising Star nomination also place concrete industry recognition behind that growing visibility.
For audiences encountering her through Trigger Point or Lollipop, there is therefore a much longer theatre and creative-development story behind the name Posy Sterling.
