William Flanagan is a British actor best known for playing Joseph Brown in ITV’s long-running soap opera Coronation Street. He joined the programme as a child and has grown up in front of television viewers. Known professionally as Will Flanagan, he has built valuable experience in television and short films. His career also attracts interest because his twin sister Isabella and older sister Amelia are successful young actors.
Who Is William Flanagan?
William Flanagan is a young screen actor from England. His best-known role is Joseph Brown, the son of Chesney Brown in Coronation Street. The role has given him a steady place in one of Britain’s most famous television programmes.
William began acting at an early age and quickly developed the discipline needed for professional filming. Soap production involves long days, repeated scenes and learning scripts quickly, making his continued work an impressive achievement.
His acting career includes television drama, soap opera and independent short films. This range has allowed him to develop different performance skills while continuing his main role on the ITV soap.
William Flanagan Age and Early Life
One entertainment database gives William Flanagan’s date of birth as 12 January 2011. Based on that date, he is 15 years old in September 2026. ITV and his acting agency do not publish a fully confirmed birth record, so the date should be treated with care. William grew up in a supportive family connected with the entertainment industry. His parents, Chris and Rachel Flanagan, have helped their children manage auditions, filming schedules, education and family commitments.
The Flanagan family has strong links with Leeds and West Yorkshire. William’s early interest in acting developed into professional work when he was still a young child.
William Flanagan’s First Acting Roles
William began acting at the age of five. His first credited television role came in the ITV crime drama Paranoid, which was broadcast in 2016. In Paranoid, he played Luke. The drama gave him early experience of working with professional actors, directors and production crews before he joined a daily soap opera. Starting in television at such a young age helped William learn how to follow direction and deliver natural performances. These skills became especially useful when he later took on a regular role in Coronation Street.
William Flanagan in Coronation Street
William joined Coronation Street in 2017 as Joseph Brown. The character had first appeared in the programme in 2011 and had previously been played by other young actors. Joseph is the son of Chesney Brown, played by Sam Aston. William’s scenes with Sam Aston created a believable father-and-son relationship and helped Joseph become an established part of the Brown family. The role has allowed William to work with experienced actors and take part in family, school and emotional storylines. His performance has developed as Joseph has grown older and faced more serious challenges.
Joseph Brown’s Place in the Story
Joseph Brown is part of a large and busy family in Weatherfield. His character often faces the everyday pressures of childhood while living in a household filled with family disagreements and personal struggles. William plays Joseph with a calm and natural style. His performance works well in family scenes because he presents the character as believable rather than exaggerated. Joseph’s storylines have also allowed William to handle difficult subjects. This has helped him move beyond simple child scenes and demonstrate greater emotional range.
The Lyme Disease Storyline
One of Joseph’s most important storylines came in 2024 when he became seriously unwell. After suffering worrying symptoms and collapsing at home, Joseph was taken to hospital and diagnosed with Lyme disease. The storyline showed the family trying to understand his illness and find the right medical support. The condition was connected in the drama to a possible tick bite during a camping trip.
Coronation Street worked with Lyme Disease UK while developing the storyline. This helped the programme present the symptoms and treatment in a responsible way. Joseph eventually made a good recovery. The storyline was fictional and did not confirm that William had Lyme disease in real life. It was important for his acting career because it gave him several serious and emotional scenes.
William Flanagan’s Film Work
Although Coronation Street is William’s best-known production, he has also worked in short films. These projects have helped him explore different characters and storytelling styles. His credits include Forbearance, released in 2018, where he played Young Chris. The film focuses on the relationship between a father and son and gave William experience outside the fast pace of soap television.
He also starred in Lia IRL, a short film about a young boy with learning difficulties who forms a connection with a voice-activated artificial intelligence assistant. William played Simon, the central young character. Another project connected with his work is Little Pains, a 2025 short film directed by Milda Baginskaitė. These film roles show that William is building experience in both television and independent cinema.
William Flanagan and His Acting Family
William Flanagan is the twin brother of Isabella Flanagan. Isabella plays Hope in Coronation Street, meaning the twins work on the same programme while portraying cousins rather than brother and sister. Their real-life connection has attracted interest from soap fans. They have attended public television events together and have shared family moments on social media.
William’s older sister Amelia Flanagan plays April Windsor in Emmerdale. Amelia joined the ITV soap in 2014 and became a recognised young performer through her long-running role. The three siblings are connected with two of Britain’s biggest soaps. William and Isabella work on Coronation Street, while Amelia works on Emmerdale. Their success is unusual because all three began acting at a young age.
Family Support and Education
Chris and Rachel Flanagan have spoken about supporting their children without forcing them into acting. The children auditioned because they enjoyed performing and wanted to continue. Their parents have also worked to keep education important. When filming affects school hours, young performers may receive tutoring on set. This allows them to continue learning while meeting production demands. The family’s support has helped William balance acting with a normal teenage life. His parents also help manage travel, auditions, filming and public appearances.
Awards and Recognition
William received important recognition in 2025 when he was nominated for Best Young Performer at the British Soap Awards. The nomination recognised his work as Joseph Brown in Coronation Street. He was nominated alongside his sister Amelia, who plays April Windsor in Emmerdale. Amelia won the award, while William’s nomination still marked a major moment in his career. The nomination showed that William’s work had gained attention beyond regular soap viewers. It also placed him among other talented young performers from major British television dramas.

A post from Disneyland Paris showed his enjoyment of a family holiday, while another showed him playing golf with Sam Aston.
The golf post highlighted the friendly connection between William and Sam Aston away from the programme. Their on-screen relationship as Joseph and Chesney has developed into a strong working partnership.
