Sarah was born Sarah Phillips in Bristol on 27th November 1996 to Robert and Beverly Phillips, and is the latter's only child. Sarah's parents separated when she was three, eventually divorcing. Robert married a woman named Diane, with whom he would have more children (Sarah's half-siblings)- Karl (b. 2002) and Kerrie (b. 2006). Sarah was raised by her mother but remained in contact with her father, though that contact became strained as Sarah's relationship with her stepmother deteriorated.
In 2011, just before the start of her fourth year at secondary school, Sarah and her mother moved to London, where Sarah was enrolled into a new secondary school. On her first day, she found herself sitting next to a boy named Nick, whom she would later befriend during her first lunch break at the school.
