Creech Jones specialised in Colonial affairs in Parliament, especially those in Africa. In June 1936 he pressed the Government, which were encouraging colonies to set up memorials to King George V, to follow the example of Uganda and set up a technical educational institution. The Labour Party nominated him to the Colonial Office's Educational Advisory Committee in 1936, on which he served for nine years. In 1937, he was a founding member of the Trades Union Congress Colonial Affairs Committee, and in 1940 he founded the Fabian Colonial Bureau.
