Cook was born in Bournemouth, Dorset on 4 January 1967.
Cook was a jet engine technician in the Royal Air Force from 1983 to 1991. She served on Tornado aircraft and in 1985, at the age of 18, saved the life of a colleague following an explosion on an aircraft.
After spending most of the 1990s in Saudi Arabia, she returned to the UK in 1998 where she became a photographer with a varied portfolio, including stints as club photographer at AFC Bournemouth and a long connection to Peter Doherty and The Libertines.
Supported by the activist group Momentum and trade union Unite the Union, she sought the Labour Party's nomination to stand again in the 2019 general election. She was removed from the shortlist over questions about the bankruptcy of a previous company she ran, but the process was stopped after the other two candidates withdrew in protest. The selection began again with Cook on the shortlist, but she wasn't selected. She stood as a independent candidate instead, but withdrew from active campaigning, citing harassment that she was receiving and its effect on her mental health as the reason for doing so.
In 2019, she set up the Sophie Cook Foundation in order to tackle the stigma surrounding mental health in schools, colleges and universities.
Cook is a transgender woman, and began to transition in 1998. Having struggled with her gender identity from childhood and with her mental health, notably posttraumatic stress disorder, self harming and suicidal ideation both during and after her military service, Cook transitioned in July 2015 while working at AFC Bournemouth. In doing so, she became the first transgender person to work in Premier League football.
