As a captain he served two years and eight months in the East Indies. He was promoted to the majority of the 6th Dragoon Guards on 3 December 1800 and to the lieutenant-colonelcy of Dillon's Regiment on 24 September 1803, from which he was removed to the 71st Regiment of Foot on 16 August 1804 and then to the 2nd Dragoon Guards on 30 July 1807. He was granted brevet rank as a colonel on 1 January 1812 and promoted to major-general 4 June 1814.^[3]

Beresford was returned to parliament for Londonderry in 1802.^[4] In 1812 he was returned for Coleraine,^[5] sworn of the Privy Council and appointed Comptroller of the Household under Lord Liverpool.^[6] In 1814 he was elected to parliament for County Waterford.^[7] He did not sit in parliament between 1826 and 1830 but nonetheless continued as Comptroller of the Household. He was once again returned to parliament for County Waterford in March 1830^[7] and remained as Comptroller of the Household until the Whigs came to power under Lord Grey in late 1830. He continued to represent County Waterford in parliament until the 1831 general election.^[7]

Beresford married Harriet Schutz, daughter of John Bacon Schutz, Esq. of Gillingham Hall, Suffolk, on 22 November 1808. They had three daughters:

• Elizabeth Harriet Georgina (1810–1889), married Admiral Henry Eden.
• Harriet Susan Isabella (d. 1859), married George Dunbar, MP for Belfast.
• Caroline Susan Catherine (d. 1866), married Hon. Edward Kenyon, of Maesfen, Shropshire.

Beresford died in October 1839, aged 58. Lady George Beresford, who was noted as an amateur painter, died in April 1860.^[2]
