This heavy ring of five was augmented to six bells during 1997 with the addition of a bell formerly hung at Apethorpe, Northamptonshire.

There are plans to augment the heavy ring of four to five by adding a bell formerly hung at Mawnan, Devon. Great Catworth bells are unusual in that the treble and second have strike notes only 28 cents apart instead of 100 cents.

The ring of three bells has been augmented to four by adding a former clock bell from Halifax. The existing ring required slight re-tuning as the ring was approximately treble, three and tenor of four.
The work was initiated to mark the 150^th anniversary of the church and the Trust supported the scheme by donating the ex-Halifax bell.

It is hope that the ring of three bells will be augmented to four by adding a second-hand bell located by the Trust.
