In 1704 he succeeded to the considerable estates in Berkshire on the death of his father. He was admitted at Middle Temple in 1712 and was educated at Eton College in about 1716. He matriculated at The Queen's College, Oxford on 5 July 1716, aged 17 and was awarded MA on 15 March 1721.[1] In 1736 he was appointed Verderer of Windsor Forest, retaining the post for the rest of his life.

He was returned unopposed at the 1741 British general election and at the 1747 British general election. He spoke against the Hanoverians on 18 January 1744. He was one of the prominent Tories who agreed to support Frederick, Prince of Wales’s programme in 1747, and was he was marked by the 2nd Lord Egmont for a seat on the Admiralty board on Frederick’s accession. His son, Peniston Portlock Powney, told the younger Pitt that he considered himself to have lost 20,000 pounds by his father’s connection with the Prince owing among other things to a large loan incurred during the Prince’s residence at Cliveden, which was undischarged on Frederick’s death.[2]
