There is a blocked priest's door in the south wall of the chancel, above which is a stone inscribed with the date 1653.

The Fleetwood font was moved to the cellar of the Old Chapel at Longton, and in 1886 it was transferred to the present Church of St. Andrew's in 1886.

[5][6] The memorial tablets include one to the cotton manufacturer and politician John Horrocks who died in 1804[2] and who was buried in a railed tomb behind the church.

[7] Between 2009 and 2011 the church interior underwent significant re-ordering to install underfloor heating, as the old oil-fired boiler and associated hot water pipes were in a poor state of repair.

The work involved the excavation of the entire floor in both nave and chancel, to allow installation of the new heating matrix.

Three crypts, containing the mortal remains of parishioners buried before 1856, were also discovered and were investigated by an archaeological team.

Skeletal remains were removed for examination and were eventually re-interred in the largest of the crypts before the new floor was laid.

To overcome the problem of collapsed graves in the nave, piling and concrete frames were installed to support the new floor.

During the re-ordering services were held in St. Mary's Church Hall on Cop Lane in the town.

[citation needed] In the churchyard are four structures that have been designated as Grade II listed buildings.
