Everett, who obtained a grant of arms in 1792, owed his prosperity to the Wiltshire cloth trade, being a Blackwell Hall factor at Lawrence Lane, London from about 1770. He had two brothers in Wiltshire who were clothiers, so he informed the House, 5 May 1800. One was partner in a bank at Warminster by 1783. In 1785 he was a co-founder of the bank of Newnham, Everett, Drummond, Tibbets and Tanner of 65 Lombard Street, later Everett & Co. of 9 Mansion House Street (1791). After his death the partnership, which included his brother William and his son Joseph Hague Everett, was known as Everett, Walker, Maltby, Ellis & Co. from 1812 until 1825, when it failed.
Everett purchased the Biddesden estate near Ludgershall, formerly the basis of the Webb family’s electoral interest there. In 1790 he attacked the negligent patron George Augustus Selwyn, putting up his banking partners the Drummonds. They did not then succeed; neither, on Selwyn’s death, did he succeed in inducing Selwyn’s heir, the 1st Viscount Sydney, to sell out to him, nor, in the ensuing by-election, could he secure the return of another partner, Nathaniel Newnham. But he so harassed Sydney by petition that a compromise ensued in 1793. In 1796 he replaced Newnham as Member on his own interest unopposed, secure in his moiety of the borough for the rest of his life.
Everett’s politics did not differ from those of the family he had dislodged. A member of the Loyal Livery of London,
Everett died 8 Feb. 1810, in his 70th year, at his town house, 19 Bedford Square. His son succeeded to his seat. As vice-president of the Foundling Hospital, he was buried in its chapel. His estate was valued at £100,000.
