He was a Ranger of Dartmoor Forest for life from 1752. He served as a Clerk of the Green Cloth from 1753 to 1770, rising from second clerk comptroller to first clerk and then as Master of the Household from 1771 to his death.
He represented Bere Alston as a Member of Parliament from 1747 to 1771 and from 1774 to 1780.
He lived at Nutwell Court on the south coast of Devon. He was said by Hoskins (1954) "to have wrecked the fine medieval house with his improvements demolishing the two-storied gatehouse with great difficulty in 1755-6 and cutting through the timbered roof of the 14th century chapel to make a plaster ceiling".[2]
He died unmarried in 1794 and the baronetcy became extinct. He bequeathed almost his whole fortune, including his Nutwell estate and his other lands, to his nephew Francis Augustus Eliott, 2nd Baron Heathfield, the son of his sister Anne Pollexfen Drake and her husband, George Augustus Eliott, 1st Baron Heathfield.
