Large church in Perpendicular style, with W tower, nave and chancel in one, N aisle, S aisle and S porch. Constructed of coursed yellow sandstone ashlar, the surface pecked, under slate roofs. The earlier N aisle is roughcast to the N and W. Detail includes buttresses with offsets, a plinth and stone eaves cornice. The heavily traceried windows are mainly Perpendicular with Tudor-arched heads and hoodmoulds.
Three-stage tower with string courses, sill band to upper level openings, diagonal buttresses which are almost full-height and battlemented parapets with gargoyles to angles. W doorway with Tudor-arched head and 2 orders of hollow mouldings containing planked double doors with strap hinges. Narrow trefoiled lancet to middle stage and 3-light panel-traceried louvre to top stage under a Tudor-arched head. The N and S sides each have the same openings to the middle and upper stages, and a narrow rectangular light to the lower stage. Similar louvre to E face with clock beneath sill band. This is mounted in a square frame with hoodmould, in the angles of which are small motifs with the date, 1843.
The W end of the S aisle has a 3-light window with flat head, each light with a cinquefoiled ogee head. In the gable is a narrow trefoiled light. The SW angle of the aisle has quoins and large kneelers. The gabled S porch is offset slightly to the R of centre. Shallow pointed arched entrance with 2 orders of mouldings and a hoodmould. In the gable is a tiny trefoiled light. Small diagonal buttresses to angles and large kneelers. Two-light flat-headed windows to sides of porch, the lights with cinquefoiled ogee heads. Inside the porch is a similar doorway into the church but with a Tudor-arched head and containing double planked doors. Plain roof with narrow rafters. There are 2 windows to each side of the porch, all Perpendicular, of 3 lights with cinquefoiled heads.
The E end of the church consists of the gable ends of the chancel and aisles, the chancel higher and wider. Diagonal buttresses to angles, buttresses between chancel and aisles and large cross finials to gables. Large 5-light panel-traceried E window with shallow pointed head and hoodmould with plain end bosses. The lights have cinquefoiled heads with cusped tracery above. The flanking aisle windows are 4-light under Tudor-arched heads, the lights with cinquefoiled ogee heads. At ground level to the N aisle, is the chamfered Tudor-arched head of an opening which is infilled. Doorway with similar head to S aisle, leading to a basement (probably boiler room) and approached by steps. Wooden door with open ironwork, including narrow lancets and a lock rail decorated with quatrefoils.
The earlier N aisle has a doorway with 2 windows to each side. Chamfered Tudor-arched doorway with hoodmould containing a planked door with strapwork. Three of the windows are Decorated, but were restored in the C19 to varying degrees. That to the L appears to be original; 2-light with pointed-arched head, the lights with trefoiled heads and with roundels above. The window to its R was probably similar, but its head has been replaced. To the R of the doorway, the 3rd window has C19 tracery with a quatrefoil above the lights. To the far R is a Perpendicular 3-light window with hollow mouldings under a Tudor-arched head. The W gable end of the N aisle has a 2-light C19 window as N side. The upper part of the wall is stepped in.
