Noble was born in Darley, West Riding of Yorkshire, England to Reginald and Phyllis Noble. He was cast in Nicholas and Alexandra upon recommendation to the casting director by his elocution teacher. He was chosen for the role mainly because of his resemblance to Alexei. He appeared on a single episode of The Main Chance in 1972, after which he stopped acting. After high school, he studied geology at Plymouth University. In March 2011 he was living in Northallerton with his wife Julie, whom he met in amateur dramatics, and daughter Katie (born 1988).
