Combe married his cousin and obtained her father’s business, in which he had been apprenticed. His father, a country attorney, left him an estate worth about £500 p.a. ‘His great knowledge of grain suggested the idea of becoming a brewer’ and, in partnership with his brother-in-law Joseph Delafield and George Shum, he took over Gyfford’s brewery at Castle Street, Longacre, towards the end of the century and prospered. He was variously reported to be worth £2,000 p.a. or £100,000 and in 1807 purchased Cobham Park. As a London alderman from 1790 and a member of the Whig Club since 7 May 1785, he associated himself with opposition politics. On that account he was six times passed over for the mayoralty, and in January 1794 carried a motion for a London petition for a speedy peace.
In 1795 he contested unsuccessfully the London by-election against Alderman Lushington, being caricatured as a pugilist for his known enthusiasm for the sport. After leading the opposition in common hall to the sedition bills in November 1795, he was returned third on the poll in 1796. His address emphasized his ‘abhorrence of the present disastrous war’ and his readiness to be instructed by common hall. His success was said by a government newspaper to be due to a secret coalition with Sir William Curtis; the same paper criticized the choice of a ‘man of the world’ addicted to gambling and boxing, no recommendations to the representation of ‘the first commercial city in the universe’, and styled him ‘this civic popinjay’.
Combe’s politics soon became evident in the House, though his potentialities as a speaker were doubted.
Although Combe differed from his City colleagues on most national issues, much of his time in the Commons was spent in collaboration with them in safeguarding the interests of the City. On 24 Feb. 1800, the occasion of his presenting a peace petition which he had himself promoted in common hall in the year of his mayoralty, Combe’s conduct as mayor was criticized in the House, but his colleague Curtis came to his defence, saying he had known him ‘near forty years in public and in private, and could bear ample testimony to his impartiality and worth in both ... though their politics were as opposite as light and darkness’. Farington endorsed this view in his diary, describing Combe as a man
who has been found to possess a very warm heart and great kindness of disposition. He is always ready to do acts of service when applied to, and engages by his manner. His connexion with the City has been attended with great expense to him, and he has had honour for it but not profit. In politics he is a party man, but the City have confidence in him when business is to be transacted.
Farington, ii. 110.
In June 1800, Combe promoted the London petition for the repeal of the first Act against workmen’s combinations, which succeeded, and in October another one to consider the high price of provisions. He also supported the petition for a free coal market in London, 18 Feb. 1802. Having hailed the peace, he accompanied Fox to Paris later that year. On 5 July 1803, again acting on instructions, he opposed Addington’s property tax bill, stigmatizing it as a renewal of income tax under another name; like the latter, ‘it raised an equal sum upon incomes of unequal duration’.
While he naturally supported the Grenville administration, 1806-7, and fêted them and the Prince of Wales at his brewery, he had little to say on their measures; nor did he ask anything for himself, though he applied unsuccessfully for patronage for his brother on two occasions.
On 30 May 1817, when common hall met to discuss a petition against the suspension of habeas corpus, Combe wrote regretting his continued ill-health. He had taken six weeks’ leave of absence from the House, 19 May. Henry Hunt then proposed that Combe be asked to resign, as without him the Livery lacked an effective representative at a time of crisis. After a stormy discussion the resolution was passed, ‘a cruel and wanton insult ... which had a visible effect on his enfeebled constitution’.
