 By 1840 the east wall of the chancel was out of alignment so the chancel was demolished and rebuilt to designs by the architect HJ Underwood, who retained the Perpendicular Gothic side windows with their mediaeval stained glass but dispensed with the mediaeval roof and replaced the Early English east windows with a neo-Perpendicular one.A contemporary condemned this work as ""wanton destruction"".By 1849 the nave was dilapidated so in 1852 the clerestory and west gallery were removed, the north wall was rebuilt and the north transept was added.
