Paget, nicknamed ‘Bartolo’ or ‘The Villain’ by his family, pursued a military career under the aegis of his eldest brother Lord Paget. In 1803 he was a.d.c. to the Duke of York, who was much attached to him and reluctant to let him join his regiment on his promotion to a majority in 1805. Late that year his father intended to bring him into Parliament for Anglesey on the family interest instead of his brother Arthur, who was abroad and to whom Berkeley wrote: ‘I hope it will not be long before I am to resign in your favour which I shall at all times be ready to do, for I want to see you established among us in England with a good place’.
The substitution did not take place until 1807, when Arthur was at home but reluctant to support the Portland administration, and out of respect for their courtier father retired in Berkeley’s favour. The latter, ironically, was about to go abroad, and served in the Peninsula in the Corunna campaign (1808), before retiring from the army on his return.

In June 1810 he became a lord of the Treasury in the place of Lord Desart:
the mode of his appointment was this. Perceval asked Arbuthnot if he knew of any nobleman’s son who would like to be a lord of the Treasury, Arbuthnot was a friend of Berkeley Paget’s, and named him.

Paget made little mark in the House. On 11 Feb. 1813, he defended the content of his constituents’ petition against Catholic relief. After voting for it on 2 Mar. and 13 May, on 24 May 1813, ‘by order of the Prince of Wales’,
