In the late 12th and early 13th centuries the aisles and tower were added. The tower contains a Sanctus bell dating from 1352. The church was enlarged in the 15th century and heavily restored in the 19th century , The tower and part of the south aisle survive in the present building and the foundations of a semicircular apse exist beneath the floor of the chancel.
The bell tower has a ring of six bells, all cast by Gillett & Johnston of Croydon in 1907. The church is well-known for its bell ringing and is the home of the Launton Handbell Ringers (est. 1951).
