The organ was first built in 1935 by Compton and was one of their 'Series 4' models. In 1973 the organ was rebuilt by J W Walker which saw the Diapason rank made unenclosed and a Gemshorn rank added. In 1995 the organ was overhauled by Peter Wells and saw the original electric action replaced by solid state. In 2016 the console was put on a mobile platform by and some minor changes made to the console accessories - this work being undertaken by Alistair Curtis. Most recently in 2019, the 32ft was added to the pedal division.
