The church is Grade II listed by the Department for Digital, Culture, Media and Sport as it is a building of special architectural or historic interest.

When the spire of Holy Trinity Church, Trinity Square was removed by October 1942[1] stones from the spire were used in the new drive at St John's when the entrance from Mansfield Road was walled up and a new drive created from Church Drive.

Other stones were incorporated into a wall on the Carrington Lido side of the churchyard.

[2] The organ was installed in 1949 and was obtained second hand from a private residence in Radcliffe on Trent.

The same builder rebuilt it in St. John's Church in 1949, and it was opened on 23 February 1949 by Harry Gabb, the sub-organist of St. Paul's Cathedral.
