In 1920, Ingold was awarded the British Empire Medal (BEM) for his wartime research involving "great courage in carrying out work in a poisonous atmosphere, and risking his life on several occasions in preventing serious accidents," though he subsequently never discussed the award or this period in his life.
Ingold was elected a Fellow of the Royal Society (FRS) in 1924.  He received the Longstaff Medal of the Royal Society of Chemistry in 1951, the Royal Medal of the Royal Society in 1952, and was knighted in 1958.
The chemistry department of University College London is now housed in the Sir Christopher Ingold building, opened in 1969.
