In 1772 Lubbock became a partner in the London bank of Lemon, Buller, Finlay and Lubbock of Mansion House Street; in 1785 the partnership changed to Forster, Lubbock and Bosanquet and in 1801 to Forster, Lubbock, Forster and Clarke. Finally in 1814 it was Sir John Lubbock, Lubbock & Co., the second partner being John William Lubbock, the principal’s nephew and heir.
Lubbock was an unsuccessful candidate at Devizes in 1784. In November 1795 he was one of the sponsors of the London merchants’ and bankers’ loyal declaration of support for Pitt’s government. At the ensuing election he was returned for Bossiney as a guest of Lord Mount Edgcumbe. He was granted a fortnight’s leave on 15 Dec. 1796. On 9 Mar. 1797 he met with the ‘armed neutrality’ under Sir John Sinclair, and on 13 Mar., in accordance with their aims, joined the minority in favour of Harrison’s motion for retrenchment. On 24 Mar. 1797, however, he denied that there was a shortage of specie and said that he was content to leave it to the discretion of the Bank directors to resume cash payments. In June he was one of the London businessmen who met to condemn the naval mutiny.
Lubbock appeared as a candidate for Leominster in January 1802
Lubbock followed his own line in the ensuing Parliament. He was in the minority against the Irish arms bill, 7 Aug. 1807, voted for Turton’s address critical of the Duke of York’s conduct, 17 Mar. 1809, and for inquiry into charges of ministerial corruption, 25 Mar. He went on to vote against the address, 23 Jan. 1810, and against ministers on the Scheldt inquiry, 26 Jan. and 5 Mar. The Whigs ventured to list him among their adherents. He was absent, supposed favourable to opposition, at the conclusion of the Scheldt inquiry, 30 Mar. 1810, and no further votes are known. He took a month’s sick leave on 18 Jan. 1811. He retired in 1812 in favour of his nephew and died 24 Feb. 1816.
