Hill's health declined in the late 1980s. After a mild heart attack on 24 February 1992, doctors told him he needed to lose weight and recommended a heart bypass. He declined, and a week later was found to have kidney failure. He died at the age of 68 on 20 April 1992; on 22 April 1992, after several days of unanswered telephone calls he was found dead in his armchair in front of the television. The cause of death was recorded as coronary thrombosis. Hill was buried at Hollybrook Cemetery near his birthplace in Southampton, on 26 April 1992.
