Durand served as a captain in the East India Company’s merchant service; returned to London with a ‘handsome fortune’ in or about 1762; and became a London merchant with premises at 51 Lime Street. He was also a partner in the firm of Durand and Nixon, Greenland Dock, Rotherhithe.
In 1767 he began to look round for a seat in Parliament. ‘What think you of Mr. Durand?’ wrote John Walsh to Lord Clive, 25 Nov. ‘He has had folly and impertinence enough to talk loudly about Worcester: he is now set out for Totnes.’
In 1769 he applied for a contract for victualling troops in the ceded West Indian islands, and in 1770 took it over from Anthony Bacon, his colleague at Aylesbury. In 1771 he obtained a contract for supplying the navy with masts, and during the American war received half a dozen other contracts in America and the West Indies.
In 1774 Durand again stood at Aylesbury, but was defeated, and seems to have attempted to intervene at Honiton. In 1775 he was returned as a Government candidate on Lord Edgcumbe’s interest at Plympton. During this Parliament John Robinson in an undated letter to Sandwich complained that Durand was ‘remarkably slack’ and could not be depended on; but in 1780 he appears in the five extant division lists, each time voting with Administration.
Durand continued to vote with North till his fall, though Sandwich, two days before the division on Conway’s motion against the war, 27 Feb. 1782, told Robinson he would write to Durand—‘all the rest of my friends are so orthodox that any application from me seems superfluous’.
He died 30 July 1788, aged 69.
