Neo-classical church with similarities of design and plan to non-conformist chapels, the major difference being the prominent bell-tower at the entrance end. Unusual plan in that tower is at E and sanctuary at W - reversed orientation. Of coursed bull-nosed rubble with raised tooled freestone dressings; slate roofs and wide bracketed eaves, which are extended across gable ends to give pediment treatment, small stack at W end. 2-stage square tower with long louvred belfry openings, 2 platbands; tall stepped-arched main entrance with separated fanlight over very tall 6-panel door with fixed upper panels; two shallow steps with large iron boot scrapers; recessed blind arches to the sides of the tower. On either side of the gable end, which is stepped back from the projecting tower, are small pane round-headed iron windows over further tall doorways. Side elevations of 4 bays have very large small-pane iron windows and sillband; deep plinth. At the far (W) end the sanctuary projects with lower gable end with pediment platband; the window was formerly as on the sides but now shortened at the base and with coloured glass; single storey gabled vestry and chapel wings with square headed windows project to either side.
