However, there is some surviving 13th-century work in the present building, mostly in the chancel, which is notably plainer in appearance than the nave, indicating its earlier age.

[2] The church underwent a period of extensive remodelling and expansion from 1420 to 1450,[3] including rebuilding the nave and aisles and constructing the large west tower.

[1] In 2017, a major reordering and restoration of the church interior took place, undertaken jointly by Benjamin & Beachamp Architects and Ellis & Co.

This restoration, taking some 8 months, involved lifting the church floor, improved the draining, and relaying it with underfloor heating and new stone.

[4] Masonry throughout the church was cleaned, wiring and plumbing was overhauled, and the timber ceilings were conserved by removing centuries of dust and wax and gilding the decorative elements.

[8] The principal feature of the exterior of the church is the tall west tower, which rises to 113.5 feet (35 metres)[2] high at the pinnacles, and was described in 1851 by Edward Augustus Freeman as one of the "highest achievements of architectural genius".

[2] The nave, clerestory, aisles and south porch date from the 15th century and are Perpendicular Gothic in style.

[2] The eastern gable of the nave features an elaborate bell-cot, in which hangs a small sanctus bell.

The tower is lit by a large five-light stained glass window, above which is a highly decorative fan vault, a hallmark of the Perpendicular style.

[2] There are numerous monuments in the church, including stone busts to John Locke and Hannah More dating from the early 19th century, both in the south porch.

[11] As part of the Victorian restoration of 1859–1860, a new organ was placed in the space underneath the fan vault of the tower.

In 1880, this organ was moved from underneath the tower to the lady chapel and was enlarged at the same time, also by Walker & Sons.

Ten years later, in 1621, Roger Purdue was contracted again, this time to recast the fourth bell, which had developed a crack.

It is recorded in the church accounts the bell was transported to and from Gloucester for recasting, rather than in the churchyard, showing the improved road conditions of the day.

The 1712 recast is the oldest surviving bell in the tower today, forming the present ninth of the ring of ten.

[16] In 1845, the treble and tenor were both recast, this time being taken to Charles and George Mears' foundry at Whitechapel, London, from nearby Yatton railway station.

[16] In 1930, the fifth bell (the treble of the original six, dating from the 1750 remodelling) cracked, and was recast by Mears & Stainbank at their Whitechapel foundry.

[16][15] In 2011, major maintenance took place, which involved overhauling the clappers, bearings and pulleys, and work to improve the roping of the bells, as well as painting all of the framework and fittings.

North Somerset Council issued a noise abatement notice, stating the bells cannot chime between 11pm and 7am.
