Roman pottery was found on the site during 2001/02 excavations in the crypt. However, the first written record of the church itself is dated as 951 in a charter of Westminster Abbey, referring to it as the "old wooden church", on top of the hill above the river Fleet.

The Charter’s authenticity has been called into question because the date is not within the reign of the King Edgar of England who is granting it. It may be that this is simply a scribal error and that the date should be ’959’ (DCCCCLIX). A ’Master Gladwin’, i.e. a priest, held it after the Norman Conquest and he assigned it to St Paul’s Cathedral, but with the proviso that the advowson be granted at 12 pence a year to the Cluniac Order’s, St Saviour’s foundation of what was to become Bermondsey Abbey. This assignment dates between 1086 and 1089. In about 1200 a deed was witnessed by James, the Parson, Roger, his chaplain, Andrew, the Deacon and also Alexander his clerk. In 1280 one Simon de Gardino bequeathed funds towards the building of a belfry, it is assumed this would be stone and that there were due to be bells to be cast for it.

In the Early Middle Ages the church is referred to as St Andrew Holburnestrate and later simply as St Andrew de Holeburn.

In 1348, John Thavie, a local armourer, "left a considerable Estate towards the support of the fabric forever", a legacy which survived the English Reformation, was invested carefully through the centuries, and still provides for the church’s current upkeep. In the 15th century, the wooden church was replaced by a medieval stone one. On 8 July 1563, during a severe storm, the steeple of the church was struck and badly damaged by lightning.

After being executed by hanging for the crime of serving at a Catholic Mass, St. Swithin Wells was buried in the churchyard on December 10, 1591.

The medieval St Andrew’s survived the 1666 Great Fire of London, saved by a last minute change in wind direction, but was already in a bad state of repair and so was rebuilt by Christopher Wren anyway. In what is his largest parish church, he rebuilt from the foundations (creating the present crypt) and gave the existing medieval stone tower (the only medieval part to survive) a marble cladding. Its rector from 1713 to 1724 was Henry Sacheverell, who is buried beneath the church’s altar.

The same statues from the Foundling Hospital located in Hatton Garden are above the side door of St Andrew Holborn.

Thomas Coram, founder of the Foundlings’ Hospital (first set up in a house in Hatton Garden) is also buried here, his remains were translated from his foundation in the 1960s. The organ casing (an organ played by Handel), the pulpit and the font is also from the Foundlings’ Hospital Chapel’s Bloomsbury site.

The church of St George the Martyr Holborn was built between 1703 and 1706, as a chapel of ease for the parish. It became a parish church in its own right in 1723.

In 1808, writer William Hazlitt married Sarah Stoddart, with Charles Lamb as his best man, and Mary Lamb as a bridesmaid. The twelve-year-old Benjamin Disraeli, the future Prime Minister, was received into the Christian Church in 1817.

It was on the church’s steps in 1828 that the surgeon William Marsden found a homeless girl suffering from hypothermia, and sought help for her from one of the nearby hospitals. However, none would take her in, and she died in Marsden’s arms; the horror of the experience inspired him to establish the Royal Free Hospital for the poor and destitute. Today the hospital is located in Hampstead.

In the mid-19th century, the Holborn Valley Improvement Scheme bought up the church’s North Churchyard (with many of the bodies re-interred in the crypt) and in the City of London Cemetery in Ilford (the latter also being the destination for the bodies from the crypt when it was cleared in 2002-2003) to make way for the Holborn Viaduct, linking Holborn with Newgate, which was opened by Queen Victoria in 1869.

As part of this improvement scheme the church received compensation to replace its assets, and the Gothic architect Samuel Sanders Teulon was commissioned to build a new rectory and court house on the south side of the church - this now operates as the offices for the foundation, the associated charities and the Archdeaconry of Hackney, as well as the rectory and the conference rooms. Teulon incorporated into the court room, the building’s main room, a 17th-century fireplace. This was from the ’Quest Room’ for the ’below Bars’ part of the parish i.e. that lying outside the city boundary sited as part of a block of buildings in the middle of the main street. This block was removed as part of the Holborn Viaduct improvements and explains why Holborn is so wide at this point.

In Charles Dickens’s ’Oliver Twist’ Bill Sykes looks up at this church’s tower (an episode referenced by Iris Murdoch in ’Under the Net’, though from where her character stands such a view is almost impossible).

During the London Blitz, on the night of 7 May 1941, the church was bombed and gutted by German bombs, leaving only the exterior walls and tower. However, instead of demolition which sometimes occurred in similar cases, it was decided after a long delay that it would be restored "stone for stone and brick for brick" to Wren’s original designs.

The church re-opened in 1961 as a non-parochial Guild Church intended for serving the local working rather than resident community which had declined as had the City’s population as a whole.

In January 2005 a new large icon was installed, made for the site by the Monastic Family Fraternity of Jesus in Vallechiara. The church runs a selection of recitals and lectures, as well as weekly services and evening concerts.
