The parish inventory of 1552 records four bells plus a Sanctus bell. They included the Great Bell which had been cast for St Mary's when Thomas Kidderminster was Prior (1403–39). In the Commonwealth era cracks were found in the bells, so in 1656 Bryan II Eldridge of Chertsey, Surrey melted them down and recast them as a ring of five and they were re-hung in a new frame. In 1734 Joseph Smith of Edgbaston recast the second bell and in 1793 John Briant of Hertford recast the treble bell.
