Her career began in 1992 when, at the age of 15, she starred in the miniseries The Leaving of Liverpool, for which she was nominated for an AACTA Award. Subsequent television work has included Waterloo Road (2007–2009), Casualty (2010–2013), Little Boy Blue, Clink (2019), Wolfe (2021), and Emmerdale (2024).

For her portrayal of Manda Miller in Adolescence (2025), Tremarco won the British Academy Television Award for Best Supporting Actress, and was nominated for the Primetime Emmy Award for Outstanding Supporting Actress in a Limited or Anthology Series or Movie, Critics' Choice Award for Best Supporting Actress in a Limited Series or Movie Made for Television and Actor Award for Outstanding Performance by a Female Actor in a Miniseries or Television Movie.

Her film credits include Priest (1994), Under the Skin (1997), Face (1997), Anita and Me (2002), and Hector (2015).

Early life and acting debut Educated at St Cecilia's Catholic Infant and Junior Schools and then Holly Lodge Girls' College, Tremarco was invited to join a newly-opened dance and drama school after being spotted in a school play. For her portrayal of headstrong orphan Lily, Tremarco was nominated for the AACTA Award for Best Lead Actress in a Television Drama. In a similarly positive review, Brian Logan of The Guardian wrote, "[The film's] chief virtue is its star, Christine Tremarco, [who] does teenage rage more viciously than I've ever seen it". That same year, she appeared in the Channel 4 television film Dockers (1999), a BAFTA-nominated drama based on the Liverpool dockers' dispute.

2000–2009: Theatre, film, and Waterloo Road Tremarco's performance in David Harrower's Presence at the Royal Court Theatre in 2001, where she played a German waitress desperate to reinvent herself as American, was well received by critics. Following substantial parts in the films Anita and Me (2002), Gifted (2003), and The Trouble with Men and Women (2005), as well as a key role in the first series of the critically acclaimed BBC/HBO thriller Five Days, she began appearing as Davina Shackleton—a learning support assistant—in the school-based BBC drama Waterloo Road; a role she played from 2007 to 2009. She then starred as Ellie Morgan, a woman facing bankruptcy and forced to sell her home, in an episode of the BBC anthology series Moving On, broadcast in May 2009.

2010–present: Television roles and Adolescence success In January 2010, Tremarco guest-starred in two episodes of the BBC's long-running medical drama series, Casualty. Owing to positive audience feedback, her character—A&E nurse Linda Andrews—was reintroduced as a regular on the show the following year. Upon her departure from Casualty in May 2013, she played supporting roles in the miniseries Glue (2014) and Safe House (2015), had a small part in the 2015 film Hector, and co-starred as Marie Thompson—the parent of a gang member involved in a murder cover-up—in the factual ITV drama Little Boy Blue (2017).

Following a mixture of leading and recurring roles in television series such as Clink (2019), Wolfe (2021), The Responder (2022), and The Gathering (2024), Tremarco joined the cast of ITV's long-running soap opera, Emmerdale, where she appeared as the free-spirited Rose Jackson for four months between April and August 2024.

Tremarco's performance in the four-part crime drama series Adolescence, which debuted on Netflix in March 2025 to record viewing figures, was particularly well received. Writing for The Guardian, Michael Hogan described her work as Manda Miller—a distraught mother reeling from the news that her 13-year-old son has carried out a fatal stabbing—as "heartbreaking"; while Nandini Balial of RogerEbert.com felt she was "a revelation". It was announced in July 2025 that Tremarco had been nominated for a Primetime Emmy Award for her portrayal of Miller. She also won the British Academy Television Award for Best Supporting Actress in 2026.
