Inside, the chapel has a plain design without galleries. It features a boarded curved ceiling and a pulpit with thin balusters leading to the steps, a plain front, and turned angle balusters. The pulpit has a panelled back, and there are three rows of raked pews. The set fawr has a balustraded back, and there are two internal porches.
