Bouverie was returned to Parliament for Downton in December 1779, but was unseated on petition already in February of the following year. He was once again returned for the constituency in 1790, and continued to represent it until 1796. From 1802 to 1806 he was a Commissioner for auditing public accounts.[2]
The latter year he was returned for Downton for a third time, and now held the seat until 1812 and again between 1819 and June 1826, when he lost his seat. However, he was once again elected in December 1826, and continued to sit for the constituency until 1830. In 1829 he had been appointed a Metropolitan Commissioner for Lunacy, which he remained until his death. Bouverie was seldom active in the House of Commons and is not known to have ever spoken.[2]
On 9 March 1779, Bouverie married Mary Wyndham Arundell, daughter of the Hon. James Everard Arundell (a son of 8th Baron Arundell of Wardour) and Ann Wyndham.[5] Together, they were the parents of:
Henry James Bouverie (1781–1832), a Commissioner of Customs.[5]
