In the 18th century galleries were added to the nave and aisles to increase seating capacity. A gallery in the north aisle was added in 1751, followed by one in the south aisle in 1760. No record survives of when the west gallery for church musicians was added, but it is known to have existed by 1772. All three galleries were removed in 1850. Two years later a second Anglican church for Kenilworth, that of St John the Evangelist, was completed on the south side of the town, relieving the crowding of St Nicholas'.
