The church is Grade I listed by the Department for Culture, Media and Sport as a building of outstanding architectural or historic interest.

The organ has been designed as a recital instrument, and to provide support for congregational singing, as well as accompanying the church's choir.

'[13] In 1723–4, the Chamberlains' Account record a payment of £1 to the Sexton of St Peter's for ringing a 4 o’clock bell.

[15] On Thursday 15 October 1846, as Richard Ward, a man employed by Messrs. Taylor and Garrett, was assisting in taking down the old face of St. Peter's church clock, when it gave way.

[16] The new clock was installed in 1847, manufactured by Reuben Bosworth at a cost of £125 (equivalent to £14,429 in 2023)[17] and was at the time, the largest in Nottingham.

[20] New cast iron clock dials, 7 feet (2.1 m) in diameter were presented by Henry Smith to the church in 1872[21] at a cost of £66 (equivalent to £7,443 in 2023).

The strike was provided by a hammer on the hour bell on E. This was replaced by an electrically driven clock by Smiths of Derby in 1965.
