It is an active Anglican parish church in the deanery of Wigan, the archdeaconry of Warrington, and the diocese of Liverpool.

The Parish of St. Peter's was abolished and merged with the nearby parishes of All Saints Hindley, Good Shepherd Bamfurlong, St. John's Hindley Green, St John the Evangelist Abram, St. Nathaniel's Platt Bridge and St John and St Elizabeth Bickershaw to form the new 7 church parish of Chapelfields.

The restructuring was strongly opposed by many worshippers in the church community, with petitions and protests being organised in opposition.

Many worshippers chose to boycott the church as a result of the new parish reorganisation and the perceived loss of community cohesion.

St Peter's is constructed in rock-faced stone with ashlar dressings and has a slate roof.

The tower has diagonal buttresses, a stair turret to the east, and a three-light north window.

[2] The stained glass includes a window dated 1881 to the memory of a nine-year-old child; it incorporates his photograph twice.

[8] In 1977 most of the alterations made by Cowan were reversed by the Pendlebury Organ Company of Cleveleys, who also added a new detached drawstop console.
