At the age of eighteen he was presented with an appointment to the Bengal civil service, which had been placed by the court of directors at the disposal of his uncle Lord Heytesbury, nominated as Governor-General of India in 1835 (by Robert Peel, but the nomination was cancelled by the fall of Peel's administration). Reaching India in 1836, Beadon spent time in district offices administration, and was serving as magistrate of Murshidabad when in 1843 he was appointed under-secretary to the government of Bengal.
From that time his promotion was rapid. After filling posts in the revenue administration, he was selected in 1850 by James Broun-Ramsay, 1st Marquess of Dalhousie to represent the Bengal presidency on a commission on the postal system. He then held in succession the posts of secretary to the government of Bengal, secretary to the government of India in the home department, foreign secretary, member of the council of the governor-general (1860–2), and finally that of lieutenant-governor of Bengal (1862–6). He was backed by three Governors-General, Hardinge, Dalhousie who consulted him on internal administration, and Canning. During most of the Indian Rebellion of 1857, Beadon was home secretary.
In Bengal, measures Beadon implemented in the Assam tea trade were held to have caused a slump, and the mission of Ashley Eden to Bhutan went badly, and was followed by the Bhutan war. The Orissa famine of 1866 found him absent from Calcutta for health reasons. The Governor-General, Sir John Lawrence did not overrule Beadon's view of the famine. The report of a commission of inquiry on the handling of the famine was unfavourable to Beadon, who left India and returned to England.
He died on 18 July 1880 in his sixty-fifth year.
Orissa famine
During the Orissa famine of 1866, he did nothing to alleviate deaths from famine, as he was concerned about tampering with the natural laws of economics. He remarked that "Such visitations of providence as these no government can do much either to prevent or alleviate," and that if he attempted to alleviate deaths from famine, he would consider himself "no better than a dacoit or thief." He maintained this viewpoint in spite of the fact that India exported over 200 million pounds of rice to Britain during the period of famine.[1]

In 1837 he married firstly Harriet Sneyd (1818–1855) daughter of Major Ralph Henry Sneyd (1784–1840) of the Bengal cavalry, with whom he had ten children; and in 1860 he married secondly Agnes Stendale (1836–1906), daughter of William Handley Sterndale (1791–1866) and sister of Robert Armitage Sterndale, with whom he had ten more.
