In 1834 there was a two manual organ by John Gray that cost £370.  The organ gallery at the west end was removed in January 1869, when the north aisle was extended and an organ chamber included at the east end, opening out into the Chancel.  A new organ was built by Gray and Davison, incorporating some pipework from the old one.  This organ of two manuals and pedals cost £280 and was opened on 10th July 1870.  Additions to the specification included a 4ft Flute on the Great in 1883 (replacing a Great reed).  A Vox Humana and a Tremulant were added on the Swell and the Swell Fifteenth removed and replaced by a Salicional (8ft, TC) in 1905.  At the same time, a 16ft Bourdon, also playable on the Pedals, was added to the Great.  A balanced Swell pedal was fitted in 1954.

In 1976 the organ was rebuilt by Bishop & Sons of Ipswich with Laurence Elvin as consultant.  The Pedal department was enlarged to six stops. The Bourdon of 1905 (from the Great) was made available additionally at 8ft pitch and the former Swell Open Diapason (which included some 18th cent. pipework) was transferred to the Pedal as an 8ft Principal, also available at 4ft, and a new 16ft Posaune added. The action was converted to electro-pneumatic – except for the 16ft Grand Open Diapason that remained mechanical.  On the Great, two new ranks were added to Mixture and the open 4ft Flute was replaced with stopped pipes.  The Swell soundboard was replaced by one of full compass, the Salicional increased in scale and revoiced, and a 2ft Gemshorn and 3-rank Mixture added.  The 8ft Oboe was extended with two new bottom octaves and became a 16ft Bassoon, the Cornopean revoiced and the Vox Humana discarded. Nicholas Pitts undertook restoration of the organ in 2001.

Despite its history, the character of the instrument has not changed.  It has been said that it was and still is an English organ of the mid-Victorian period, and as such is an organ par excellence for use in Anglican worship.  National Organ Register No. D03976.
