All Saints’ Church is the oldest building in Loughton, and stands on what is probably an artificial mound. The oldest part of the church is the Chancel, at the east end; the original walls date from the 13th century.
Early in the 15th century the Nave was added, with the half-columns supporting the Tower arch. (The shape of the windows near the tower, and behind the altar has been altered over the years).
To this modest structure was added in the 1480s, the fine perpendicular South Aisle with its splendid moulded roof, carved bosses, and crenellated parapet, and a new west tower with west door and window. The tower is 46ft. high and houses six bells and a clock.
The church was restored around 1826, and again between 1877 and 1883 by E. S. Harris. Internally, box pews were replaced by open pews in the 1870s. Possibly also at this time the gallery at the west end was removed. The Organ, by Bevington of London was installed circa 1870 and altered in 1880. A major refurbishment of the tower was carried out in 1984.
In 1990 the south aisle and porch were restored, and the bracing rods fitted; at the same time work to combat damp in the north east corner of the nave resulted in the discovery of a hidden stairway to a former Rood loft. The Church room to the north was added in 1994, connected to the church through the original north door which had been blocked-up for many years.
The Organ was refurbished in 1999 by Robert Shaftoe of Stevington. The external clock face was re-gilded for the Millennium. In 2010 the pews were removed and a new limestone floor with underfloor heating was laid.
