The union was founded in 1915 when the Post Office Engineering and Stores Association and the Amalgamated Society of Telephone Employees merged, to form the Post Office Amalgamated Engineering and Stores Association. In 1922, following the establishment of the Irish Free State, the union's Irish section split away to form the Irish Post Office Engineering Union. In 1925, the Post Office Telegraph Mechanicians' Society joined the union. However, by 1939, membership was only 39,000.
