In November 1900, he was appointed Master of the Buckhounds under Lord Salisbury. However, as Chesham was serving in South Africa, Lord Churchill was appointed to act as Master of the Buckhounds in his absence. Chesham remained Master until the office was abolished the following year. He was admitted to the Privy Council in July 1901, and also served as a Lord of the Bedchamber to the Prince of Wales (later King George V) from 1901 to 1907.
