The nave and chancel are carried on five pairs of piers and the interior has a boarded wagon roof coloured in blue, crimson and gold which stretches the whole length of the church. At the time of the construction of the Bristol and Exeter Railway, William Froude – the engineer given responsibility for this section of the line by Isambard Kingdom Brunel – inserted iron stringers to prevent the walls from spreading as a result of vibrations from the trains. A screen runs across the whole width of the church.
