However, he lost his seat in 1885 and once again stood unsuccessfully for the constituency in 1886. In 1888 he was successfully returned for Southwark West in a by-election, a seat he held until 1910. He served under William Ewart Gladstone and the Earl of Rosebery as a Junior Lord of the Treasury between 1892 and 1895 and continued as Liberal Whip until 1905. When the Liberals returned to power in December 1905 under Sir Henry Campbell-Bannerman, Causton was made Paymaster-General. In January 1906 he was sworn of the Privy Council. He remained as Paymaster-General until 1910, the last two years under the premiership of H. H. Asquith. He lost his seat in parliament in 1910.
