He was the brother of Henry Paget, 1st Marquess of Anglesey, Sir Arthur Paget, Sir Edward Paget, Sir Charles Paget and Berkeley Paget.^{[citation needed]} He was educated at Westminster School from 1779 to 1781, prior to entering the Royal Navy.^[1]

From Midshipman rank in 1783, Paget served in the Navy and achieved the rank of captain in 1793.^[1] On 17 July 1794, while commanding the 50-gun Fourth Rate HMS Romney, he captured the French frigate Sibylle, known as 'one of the largest the French had',^[1] at the Battle of Mykonos. In the two years before his death he also captured ten French merchant vessels.^[1]

In 1790 he was returned to parliament for Anglesey, succeeding his uncle Nicholas Bayly, a seat he held until his death four years later. His younger brother Sir Arthur Paget succeeded him as MP.^[2]
