As Member for Maldon on the Strutt interest, Harvey rallied to Pitt’s ministry in 1784, but did not seek re-election that year. In 1790 he resumed active service in the navy. He served in the reduction of Martinique and Guadeloupe and was again in the West Indies 1796-7. By 1799 he had retrieved his affairs after losing some £60,000 at gambling and was worth £5,000 p.a. He was with the Channel fleet in 1802 when, on the retirement of Bramston as county Member, he stood for Essex, which his father and brother had represented. Lord St. Vincent informed Bramston, 20 May 1802, that
the only consolation I feel for the loss of your public services is in the hope of my friend Captain Harvey being your successor, and I wish most heartily I had any influence to offer him, for a more zealous officer does not exist.

Harvey was returned unopposed on the ‘old Tory’ interest which had returned Bramston, though his wife was connected with the Grenvilles. He spoke in the House from time to time, mostly on naval matters. He favoured the inquiry into naval abuses, 18 Dec. 1802, and on 6 July 1803 regretted that naval defence was not being debated,
Meanwhile he had been one of the heroes of Trafalgar. His relatives the Grosvenors had wished Pitt to bestow an Irish peerage or the red ribbon on him.
On 14 Apr. 1809 the House was informed that Harvey was shortly to be tried by a court-martial at Portsmouth. His ‘intemperate manner’ was a byword in the profession, and he was found guilty of using threatening language to Lord Gambier and of speaking disrespectfully of him to other officers. His anger arose out of Lord Cochrane’s being given a special command. He was dismissed the service, but reinstated on petition, 21 Mar. 1810.
In the session of 1812 he again spoke on the naval estimates. On the subject of flogging servicemen, he insisted, 10 June 1808, 16 Mar. 1812, that the French were also given to it. He opposed the sea water baths bill, 9 Apr. 1812, out of deference to the fear of the Essex gentry that they would be overwhelmed by metropolitan bathers. On 4 May he opposed the sinecure offices bill. He pressed for an additional grant to the assassinated Perceval’s family, 13 May, and on 15 May seconded the motion for a monument to him in Westminster Abbey. On 21 May he was in the majority for a more effective administration, but, it appears, opposed to the address being carried to the Regent by the privy councillors. He was called to order by the Speaker while trying to justify this, but snubbed when he attempted to revenge himself by calling Whitbread and Charles Williams Wynn to order. He voted against Catholic relief, 22 June, and against the leather tax, 1 July.
Harvey faced a contest for Essex in 1812. His son-in-law hinted, 3 Oct.,
nothing but your being employed upon the American station (supposing war to be certain) could repay the loss. And unless your being Member for Essex is the main object, you may have a seat in Parliament for a fifth of the expense. Why not exchange with Mr Western?
(Charles Callis Western was vacating his seat for Maldon to contest the county, but the suggestion was not practicable). Harvey, who found that his colleague was not prepared to share the expenses, wished to give up ‘that wrangling House of Commons’ but to do so without loss of character: ‘I am complained of for not visiting the different towns, but I am idle and like my farm better than the blackguard canvass of low and interested free-holders’. He added that he would doubtless have to face ‘a second edition’ of the contest ‘within two or three years’.
