Born in Newry, Renshaw studied at the Newry Intermediate School, Queen's College, Galway and Queen's College, Belfast, before becoming a teacher at the Croydon High School. In 1911, he moved to become Principal of the Shaftesbury House Tutorial College.[1]
In 1943, Renshaw was elected to the Northern Ireland House of Commons to represent the Queen's University of Belfast for the Ulster Unionist Party, although he did not stand at the 1945 Northern Ireland general election.

In his spare time, Renshaw was a member of the Freemasons.[1]
