He was appointed Clerk of the Signet in 1655 and Clerk of the Privy Council in 1660, holding both positions for life, and in 1661 was created a Knight of the Bath. He also served as a justice of the peace for both Wiltshire and Surrey, and as a Commissioner of Assessment for several counties. He was Keeper of Windsor Great Park from 1669 to 1671 and Deputy Lieutenant of Dorset from 1672 to 1674.

In 1661 he was elected to the Cavalier Parliament for Ripon, Wilton and West Looe, choosing to sit for Ripon and holding the seat until 1679. He was then elected to serve in three consecutive Parliaments for Wilton, sitting until 1687.

He inherited his father's West Horsley estate in Surrey in 1669. He died in 1705 and was buried at West Horsley. He had married Lady Penelope Compton, the daughter of Spencer Compton, 2nd Earl of Northampton, and with her had three sons and a daughter.
