Active in communal affairs, Rabbi Ferber established the Chesed V’emeth Burial Society in 1915. He helped found the London yeshiva and was for many years the honorary secretary of the London "Vaad Harabonim" (rabbinical council) and chairman of the Association of London Rabbis ("Hisachdus Harabonim"). A member of its World Rabbinical council, Rabbi Ferber gave valuable assistance to the Agudas Yisroel movement. He closely collaborated with Rabbi Dr M Jung and Rabbi Dr V Schonfeld in Shechita and other communal issues. He was a friend of Rabbi Avraham Yitzchak Kook, Chief Rabbi of Palestine, from the time that the latter was Rabbi of Machzike Hadath in London.
