It is a Grade I listed building and surviving parts of the structure date back to the Middle Ages.

The churchyard contains the grave of the political activist William Cobbett, and there is a memorial to the hymn-writer Augustus Toplady.

The oldest record is in the Domesday Book of 1086, which states that the Manor of Farnham was held by the Bishop of Winchester, and that the church was 'richly endowed'.

In addition, a chantry chapel was built on the north side of the church, dedicated to the Virgin Mary.

In the early 16th century, a new tower was built at the west end of the church; it was quite small, rising up no more than a couple of metres above the roof of the nave.

[3] From 1990 to 2005, fundraising and planning efforts were made for a large-scale conservation project that would reinforce and repair the building's structure and foundations.

[3] The stonework of the east window has not changed since the Middle Ages, but the present glass was installed in the 19th century.

[7] The church is open every day with morning and evening prayer on Mondays, Tuesdays and Thursdays.

Also the church has mission and outreach groups that promote Fairtrade products and the Make Poverty History campaign.

[8] In 2022 the church was used as a location in the BBC One television mini-series Inside Man, with David Tennant as Reverend Harry Watling.
