The diocese was set up in 1872. Originally, the area was nominally under the charge of the Bishop of London, a situation which had been assumed to hold from 1660 onwards. In 1813, the then Bishop of London denied it was his responsibility, and so it turned out that clergy appointments to the Church in the Colonies were recommended by the local governor, in this case the governor of the Leeward Islands. From 1824 until 1872 the area was administered by the Bishop of Barbados. The coat of arms of the diocese was granted by the College of Arms in London in 1951, and includes the Alpha and Omega and a version of the Shield of the Trinity.
