After the war Henshaw became a director of Miles Aircraft in South Africa, a job which entailed visiting potential customers in the region and making demonstration flights. But the company folded and he returned to England in 1948. Although still only in his mid-30s, he never again flew as pilot in command of an aircraft. Instead he took charge of his family's farming and holiday business interests in Lincolnshire. He was awarded the Queen's Commendation for Brave Conduct for his rescue work in the 1953 floods.
