He succeeded his father in 1568, becoming a wealthy landowner with estates near Chippenham and Devizes, and property in Westbury, Wiltshire.

As a substantial local landowner he secured his own election and that of his younger brother Henry as Member (MP) for Westbury in 1572. He represented Westbury again in 1584. He was a member of the Wiltshire bench as a Justice of the Peace from 1573 and appointed High Sheriff of Wiltshire for 1581–82.
