The fine imposing Parish Church of Holy Trinity in the seaside town of Exmouth, Devon contains an excellent example of Compton's work where a smaller instrument was replaced by something much larger but where some of the pipework has been utilised in a similar way to what was done at Derby Cathedral amongst others.

At Holy Trinity, the pipework is contained behind the casework of the original instrument on the north side of the chancel with the console opposite on the south side.

In 2002, the organ received an overhaul by Michael Farley of nearby Sidmouth which saw the installation of a new piston capture system but tonally the organ remains as Compton built it.
