Chloe Hesar was born in Gateshead, England, UK. At the age of three, she relocated to Surrey. She started attending acting classes at Laine Theatre Arts when she was 10. Eager to appear on television, Chloe auditioned for her first professional acting agency at 11. Her screen debut came at 12, when she portrayed Jen Brooks in The Bill (1984). Her first feature film role was Emily in Faintheart (2008), a comedy about an irresponsible man trying to win back his wife. She secured the part from 25,000 actresses worldwide who submitted audition tapes. The director later noted that her audition stood out because she was the only one who kissed Martin, played by Joseph Hamilton, on the cheek. Following critical praise and attention at the Cambridge Film Festival, Chloe began landing more prominent television roles. Within just four months, she appeared in M.I.High (2007), Silent Witness (1996), and returned to The Bill (1984). She was invited back for a two-part special titled The Forgotten Child, in which she reprised her role as Jen Kilshaw, a foster girl being groomed by an older teenage boy. Her performance attracted coverage in several television magazines, some of which featured images from the episode. After completing high school, Chloe studied Philosophy at King's College London. While earning her degree, she continued acting in television series including Sky One's Parents (2012), The Inbetweeners (2008), and CBBC's Sadie J (2011). She also appeared in a small role in the feature film Survivor (2015), alongside Milla Jovovich and Pierce Brosnan. Chloe graduated from King's College London in July 2014 with a 2:1 BA Honours degree in Philosophy. Soon after, she appeared in a two-episode special of BBC's Doctors (2000). In early 2015, she made her theatre debut at the Almeida Theatre, playing Mandy in Mike Bartlett's world premiere of Game. The production received four-star reviews from Time Out and The Guardian. In October 2015, it was announced that Chloe would join the regular cast of the BAFTA Children's Award-winning series Wolfblood (2012) on CBBC. Filming began in September 2015, with the series set to air internationally in 2016, including on the Disney Channel in the US. In 2016, Chloe is also set to play Shanice in Nadia Fall's production of The Suicide at the National Theatre.
