Nave and S aisle have canted wagon roofs with moulded ribs and plaster panels. The 3-bay nave arcade, of 1813, has octagonal piers and round arches with a single order of chamfer. The 2-centred arch of 1868 to the N transept also has a single order of continuous chamfer. In the N transept is a recess of a former window in the E wall, and a simple 2-centred piscina. The pointed chancel arch has 2 orders of chamfer, the outer continuous and the inner on angel corbels, and a hood mould with head stops. In the chancel is a roof of 1899, of 2 bays with half bays at the ends, the trusses composed of collar beams above diagonal braces, the space between infilled with openwork decoration. The 3-bay chancel arcade, also of 1813, has pointed arches incorporating 2 orders of chamfer, on octagonal piers. The chancel and sanctuary floor are laid with encaustic tiles.
The base of the tower has a tunnel vault. The W doorway to the nave has a continuous roll and hollow moulding.
The principal interior feature is the Jacobean memorial to Bishop Rudd. This is Renaissance in style, comprising a tomb chest with 2 raised fields, upon which are effigies of Bishop Rudd (d 1614) and his wife Ann Dalton (d 1616) in contemporary dress. Behind them, against the back of the tomb, is a slate memorial tablet framed by strapwork in low relief. The effigies lie beneath a coffered round arch on an outer order of Corinthian columns on high panelled bases, supporting an entablature incorporating a frieze of rosettes, and a panelled soffit with diamond fields. The pediment is broken by a coat of arms and bishop''''''''''''''''s mitre. The tomb chest is flanked by pairs of kneeling children, each pair framed by a canopy on a panelled base, and with fluted Ionic columns and moulded entablature. Each canopy is surmounted by a tall panelled obelisk.
The church has other significant C18 and C19 wall monuments. In the E wall of the chapel is a tablet surmounted by a psalter, to John Walter Philipps of Aberglasney (d 1848), by Lewis of Cheltenham. Another monument by Lewis is in the S chancel wall, commemorating Thomas Philipps of Aberglasney (d 1824). This is a marble wall tablet on a slate background, has a Greek-key frieze at the base, inscription, and is surmounted by a draped urn. In the S aisle is an alabaster wall monument to Rev Thomas Llwyd (d 1775) comprising an urn with putto over an inscription panel. To its R is an alabaster tablet on a slate background, by P Rogers of Swansea, to the Rev George Wade Green of Court Henry (d 1868) and members of his family, comprising a plain inscription surmounted by a bible and a dove laying a wreath.
The octagonal font is C19 in late Perpendicular style, with panelled stem and quatrefoil relief panels to the bowl. The benches, with simple pointed ends, were installed in 1868. The polygonal pulpit has early Gothic style panels. The C17 Communion rail has turned balusters and pointed arches.
Several windows have C19 and C20 stained glass. The E window shows Christ, the SE window Jesus with the Canaanite woman''''''''''''''''s daughter. The N window depicts Faith, Hope and Charity signed by Florence Cann of Smethwick, but undated. The nave NW window shows the crucifixion.
