Perring, ‘the son of a poor man’, was said in 1800 to be ‘the richest man in the whole court of aldermen’ and to ‘aspire to the honour of a seat in Parliament for the City’. The substance of his wealth appears to have derived from his uncle Peter of Membland, who
went out to India a servant to Sir Thomas Rumbold, and at length became secretary to the government at Madras, where he realized a fortune of £40,000. On his return to England, he married the beautiful daughter of a neighbouring clergyman [Lucinda, da. of Rev. Henry Manning, rector of Stoke-in-Teignhead, Devon], on whom he settled ten thousand pounds; and, in consequence of her extreme good behaviour, intended settling his whole fortune upon her; he died, however, before he could sign his will [8 Dec. 1796].
Administration was granted to Perring’s father and his uncle John in February 1797 and six months later Perring succeeded his father.
Perring signed the London merchants’ declaration of loyalty, 2 Dec. 1795, and at a meeting of common hall called to consider a petition against the income tax, 29 June 1803, expressed his support for the principle of the tax as part of the war effort. On his election to the lord mayoralty later in the year, Lord Chancellor Eldon recommended him to the King as ‘in private life a person of worth, and, in public, of sound and loyal principles’.
Perring found no seat at the ensuing general election, but he successfully applied to the Portland ministry for a baronetcy.
Perring issued his customary address to the electors of Hythe, 13 Feb. 1820, but illness prevented him from canvassing and, complaining of ‘the advantage taken of it in quarters where I considered myself most secure’, he did not go to a poll. He promised to come forward at Hythe on the first vacancy, but did not return to the House, although he was still politically active in the City in 1826.
Perring’s bank, which was said to have ‘formed at one period a considerable connexion in the City’, stopped payment on 21 Feb. 1826, following the failure of the Stock Exchange. He was said at the time to be ‘engaged extensively in the manufacture of woollens in the neighbourhood of Exeter’; but the demands of the bank’s creditors ‘could not be satisfied without the sacrifice of Sir John’s fine estates’, and at the time of his death, 30 Jan. 1831, he was living in Burton Crescent, St. Pancras.
