He was the eldest son of Harry Powlett, 4th Duke of Bolton and Catherine Parry.
Educated at Winchester, he joined the British Army and became a lieutenant-colonel in 1745. Powlett was a Groom of the Bedchamber to Frederick, Prince of Wales from 1749 until the Prince's death in 1751. He had been promoted lieutenant general by 12 March 1752, when he was made a KB.
Upon the succession of his father to the Dukedom in December 1754, he became known as Marquess of Winchester,  and he left his seat at Lymington to succeed his father in Hampshire.

On 5 July 1765, Bolton died by suicide – shooting himself in the head with a pistol in his house in Grosvenor Square; "nobody knows why or wherefore," wrote Horace Walpole, "except that there is a good deal of madness in the blood".  Unmarried, Lord Bolton entailed most of his extensive estates to his illegitimate daughter, Jean Mary Browne-Powlett, in default of male issue of his younger brother Harry. When Harry died without male heirs in 1794, the Dukedom became extinct, and the inheritance passed to Thomas Orde in right of his wife. He added Powlett to his surname and was created Baron Bolton in 1797. The properties with attached farms included Bolton Hall and Bolton Castle in North Yorkshire and Hackwood Park, Old Basing, Hampshire.
