The church is a vast space, full of white light, seeming longer than it really is thanks to the three sides of gallery. It is almost entirely a complete Georgian worship space on a huge scale, just on the eve of the Oxford Movement and virtually untouched since.
The furnishings are almost entirely original, including a grand mayoral pew (for a town of less than 5,000 people!), the late 19th century choir stalls having been removed and replaced with modern chairs. The only hint that anything happened after the 1820s is a collection of very fine early 20th century three light windows by Henry Holiday, William Morris, Powell and Son and Thomas Willement.
