Sayer was born at Bradfield in Berkshire, England. He was educated at Trinity College, Glenalmond, in Perthshire, Scotland, and at Magdalen College, Oxford, where he was tutored by C. S. Lewis. He joined the staff of Malvern College in 1945 after having been a Captain in the British Army Intelligence Corps on account of his fluent German. Sayer became Head of English in 1949.
Sayer was also a close friend of J. R. R. Tolkien. Excerpts from The Hobbit and The Lord of the Rings were recorded in Malvern in 1952, at the home of George Sayer. The recordings were later issued on long-playing gramophone records. In the liner notes for J. R. R. Tolkien Reads and Sings his The Hobbit & The Fellowship of the Ring, George Sayer wrote that Tolkien would relive the book as they walked and compared parts of the Malvern Hills to the White Mountains of Gondor.
Jeremy Paxman, a pupil at Malvern College from 1964 to 1968, described Sayer as "the most wonderful, inspirational teacher ... a profoundly decent and compassionate man ... the sort of teacher you dream of having".
Sayer became a convert to Catholicism and had a keen interest in theology.
