Liam Sharp was born in Derby at St. Mary's Hospital to parents Roger and Linda Sharp. He has a younger sister, Kerry, and younger brother, Rien. He went to School at Brackensdale Junior then infants school, before moving to Allestree Lawn Junior school because of his parents work. At the suggestion of his teachers he was advised to meet with the Gifted Children's Society, who in turn advised St. Andrew's Prep School in Meads, Eastbourne, to take Sharp on and establish their first Art Scholarship. He then went on to win the first Art Scholarship to Eastbourne College, where he stayed until his A Levels. At 17 Sharp met Don Lawrence via a mutual friend, and opted against going to university to become Don's apprentice.
