At the base of the tower is a porch with angle pilasters, a Doric entablature, and an entrance on the south side. Its convex west wall contains a round-headed window. Above this is a round window, and there are quoins on the corners, At the top of the tower is an octagonal bell stage with round-headed louvred bell openings, surmounted by a cupola with a ball finial. At the west end of the nave are round-headed windows with round windows above. The chancel has angle buttresses, a three-light east window containing Geometrical tracery, and a cross on the gable. In the chapel are a three-light east window and a two-light south window. The extension to the vestry is in the style of the nave. Interior Inside the church, the roof has elaborate king post trusses. The west gallery is carried on slim Doric timber columns, and has an entablature with a dentilled cornice. In the church is a painted board referring to an enlargement in 1830, royal arms dated 1710, and a chest dated 1740. There is a two-bay arcade between the chancel and the chapel. The pulpit is in the style of the 17th century, and was moved from St Saviour's Church in Liverpool when it was demolished. The stained glass in the east window is by Shrigley and Hunt. The first pipe organ was built in 1885 by E. Franklin Lloyd of Liverpool. This was rebuilt and extended in 1949 by Rushworth and Dreaper as a war memorial, and altered in 1970 and again in 1982 by David Wells. This organ was replaced in 2002 by Principal Pipe Organs of York, using reconstituted pipes from the previous organ, together with new pipes. In the cupola is a set of eight tubular bells. Originally they were rung manually, but since 2010 they are driven electrically. Appraisal The church was designated as a Grade II listed building on 19 July 1966. Grade II is the lowest of the three grades of listing and is applied to buildings that are "nationally important and of special interest".
