[1][9] St Helen's is constructed in the Perpendicular style of rubble with ashlar dressings.

[2] It is separated from the north and south aisles by five-bay arcades, with pointed arches and round piers.

[3] On the wall there is an inscription in Latin warning of "idle chatter in church".

[2][3] The vestry at the north-east corner of the building is mostly constructed of dressed stone, which contrasts with the rubble of the rest of the church.

It includes work by Ward and Hughes, William Wailes and Heaton, Butler and Bayne.

[3] The tower houses a ring of six bells hung in a wooden frame, that are rung from the ground floor.

[2] It contains several sandstone headstones that have received a Grade II designation from English Heritage.
