We have a peal of six bells in the tower hung for full circle ringing plus an Ellacombe chiming facility.
Prior to 1939 there were only three bells in the tower, hung for chiming. These form the 4th, 5th and tenor of the present ring.
During 1940-43 three new bells were cast and a new oak frame installed by Mears & Stainbank of Whitechapel. This was one of the first restorations carried out during the war.
The first time they were heard was when they were chimed for the Victory of El Alamein. The first peal on the bells was rung in August 1943 for the Feast of the Assumption - the wartime ban on ringing having been lifted.

The tower is affiliated to the Middlesex County Association and London Diocesan Guild of Church Bell Ringers. Further information on bells and bellringing can be found on the Ringing World web pages.
