By the 19th century the building's structure had deteriorated and become dangerous, and it was replaced by a new church, built between 1847 and 1849 to the designs of Anthony Salvin.

Some of the furniture in the church was moved from the previous building, as were some of the memorials, the majority of which are to members of the Brooke family from nearby Norton Priory.

All Saints is an active Anglican parish church in the diocese of Chester, arranging services on Sundays and home groups during the week, in addition to weddings and funerals, and running a community project.

Runcorn is not mentioned in the Domesday Book, but there is evidence that Nigel, the first baron of Halton (died 1080), conferred the church with a priest "in the days of the Conqueror".

[3] A medieval church was subsequently built on the site, during the 19th-century demolition of which Norman capitals were found in the masonry of its tower.

Judging by its Early English style of architecture, the local historian H. F. Starkey estimates that the medieval church was probably built in about 1250.

[13] The major donors were Miss Orred, the largest land owner in the town, Sir Richard Brooke, the dean and chapter of Christ Church, Oxford, and the Earl of Ellesmere.

[13] In 1910 a papal bull issued by Pope Boniface IX was found in the churchyard that referred to the dissolution of Norton Priory.

[2][15] The steeple has corner buttresses, large louvred lancets at the bell-stage, and two tiers of lucarnes springing from the base of the tower and from the broach.

The marble reredos dates from 1888, and the alabaster altar rails from 1900; both were donated by the daughter of Rev John Barclay, a former vicar of the church who died in 1866.

Mural tablets, some of which were moved from the old church, commemorate members of the Brooke family and previous vicars of the parish.

In the south aisle is a memorial to J. R. Hughes, who died at sea in 1874; "he is shown in the water wearing nothing but mutton-chop whiskers and a crown proffered by an angel".

[16] There is a ring of eight bells cast in 1851 by Charles and George Mears, the tenor weighing 15-3-15 in cwts-qtrs-lbs or around 800 kg, having a diameter of 39 inches (0.99 m) and tuned to the note E.[19] A former hearse house at the southeast corner of the churchyard dates from about 1833, and has been converted for use as an electricity sub-station.

The door opening at the front has a wide semicircular arch with a keystone and springing blocks, above which is a string course and a cornice with moulded eaves.

These were split apart when the church was demolished, with the heaviest bell being installed in Holy Trinity, Runcorn and the other four were broken up and the metal re-used in other castings.

The bells received a minor overhaul from Whitechapel in 1936, though details about what was actually carried out are largely unknown, which leads to the conclusion that the majority of the installation remains original.

There is an active band of bellringers who meet on Tuesday evenings to practice, and there is a strong focus on training and improvement due to the novice nature of the group.

All Saints serves the Old Town area of Runcorn, and arranges services on Sundays, together with baptisms, thanksgivings, weddings and funerals.
