The church of St John the Baptist was opened in November 1858 as a daughter church to St Andrew’s Enfield. It was consecrated on 31st July 1865 and became the parish church of Clay Hill in 1867.
The pipe organ in St John’s Church was built by A. Hunter of London. Although undated, it is said to have been purchased second hand in 1870, although it is possible that it could have been built for and into St John’s church. It was restored by Geo Osmond & Co Taunton in the 1960’s. In 2010, the organ was awarded an Historic Organ Certificate Grade II* (for particularly important organs of more than special interest).
The organ is located in the north wall of the chancel with the console beneath gold-painted display pipes. Before electricity was installed in 1949, air had to be pumped manually into the organ bellows using a lever in the organ loft. This was generally the task of two of the choirboys who would gain extra payment for their efforts! The organ has two keyboards each of 54 keys and a 27 key straight flat Pedalboard. Pipes are selected using draw stops.
