A direct descendant of Sir John Wyndham, he was the second but eldest surviving son of Henry Wyndham, 2nd Baron Leconfield, and Constance Evelyn Primrose, daughter of Archibald Primrose, Lord Dalmeny. His grandfather, the first Baron Leconfield, was the adopted heir of George Wyndham, 3rd Earl of Egremont, from whom the family derived their considerable wealth.

Military career
He served in the 1st Life Guards from 1892 to 1898 and He was appointed a lieutenant of the Reserve on 27 January 1900,. In 1901, during the Second Boer War, he became the commanding officer of the newly-reformed Sussex Yeomanry (originally raised at Petworth by the 3rd Earl of Egremont).

During World War I he rejoined the 1st Life Guards and commanded the Royal Sussex Volunteers from 1917 to 1918. In World War II, he was appointed Honorary Colonel of the 5th Battalion of the Border Regiment (representing Cumberland, of which he held significant lands), and of the 98th Surrey and Sussex Yeomanry. He served as Lord Lieutenant of Sussex between 1917 and 1949.

Properties
Lord Leconfield inherited the family seat, Petworth House, as well as significant land in Cumberland, including Cockermouth Castle and Scafell Pike. In 1919, he placed Scafell Pike—the highest peak in England—under the custody of the National Trust in honour of the soldiers of the Lake District who served in World War I.

Lord Leconfield also opened the state rooms of Petworth House, the 17th-century marvel with considerable artwork, to the public. In 1947, he gave Petworth and its 735-acre park to the National Trust as well.
