Cubitt was educated at Eton and Trinity College, Cambridge.^[1] He was Conservative Party Member of Parliament (MP) for Reigate between 1892 and 1906. He later served as Lord Lieutenant of Surrey from 1905 to 1939, and was appointed to the Order of the Bath as a Companion (CB) in 1911.^[2]

Cubitt succeeded to the peerage upon the death of his father in 1917. He was appointed to be a Deputy Lieutenant of the County of Surrey in 1940.^[3]
