Artistically and historically, the most significant interior fitting is a marble monument to Charlotte Mostyn (d 1694) against the nave W wall, by Grinling Gibbons. It has a panelled base with memorial inscription and flanking pilasters. Cherubs are at the base of a gadrooned sarcophagus. The sarcophagus is surmounted by a flaming urn on a plinth decorated with the Mostyn family arms, and flanked by 2 more cherubs. The monument is mounted on an earlier grave slab. To its R is a wall monument to Watkin Williams (d 1808) and his wide Elizabeth (d 1825), of white on black marble, surmounted by a draped urn, by S & F Franceys. The chancel N wall has a Gothic wall tablet commemorating Annabella Puleston (d 1824) by John Carline II. In the nave S wall are 2 lozenge shaped brass memorial plaques to William Barber Buddicom (d 1887) and Marie Jeanne Buddicom (d 1892) by Cox & Buckley of London.

The 2 N chancel windows, commemorating Flora Williams (d 1847), show a child in heaven and the Good Shepherd. The sexfoil window in the nave W wall shows the Royal Arms and is dated 1853.
