He served with the regiment in the First World War, was wounded and mentioned in despatches and rose to the rank of lieutenant-colonel.

He served as Secretary for Mines from 1922 to 1924 and again from December 1924 (after the fall of the first Labour Government) until 1928. He was sworn of the Privy Council in 1926 and was a member of the Indian Statutory Commission. On 24 July 1933 he was elevated to the peerage as Baron Bingley, of Bramham in the County of York.
