A product of the Oxford Movement, St Edward's was originally constructed in 1915, as a tin tabernacle, one of several in Cardiff at the time.

On 11 September 1919, between midnight and 1 am, the church was almost completely destroyed by a fire, believed to have been caused by an electrical fault.

Although the church was reduced to a wreck, many of the objects inside survived the blaze, including the communion vessels and 240 chairs.

A chancel of brick with sandstone embellishments was built by Willmott and Smith, but funds ran short, causing the nave to be constructed of galvanised iron.

In 1992, a brick extension to the church was added, providing a small vestibule, a washroom and a schoolroom.
