Zoë started her singing career at the age of nine when she recorded her first CD Little Ray of Light in October 2004, to raise funds for the New Oxford Children's Hospital, as a token of gratitude to the doctors and nurses who had looked after her sister, Jodie.
The album raised £100,000 for the Down's Syndrome Association and other charities relating to Jodie's condition.
Jodie died following her heart surgery, though continues to be Zoë's inspiration to raise awareness for Down's Syndrome and other disabilities.
On 19 November 2007, Zoë's third album, Once Upon a Time (produced by Andy Whitmore) was released, featuring a duet with the New Zealand tenor Geoff Sewell.
In October 2017, Zoë won a competition to be a guest soloist at Celtic Woman's World Tour, 'Voices of Angels', performing a solo at the London Palladium.
