Colnbrook only became a parish in its own right in 1852. Prior to this it was served by clergy from Stanwell, Horton, or Langley. The Church was consecrated by the Bishop of Oxford, Samuel Wilberforce, on July 7th (the Sunday nearest to St Thomas’ Day – 4th July) 1852. 

The architect was Benjamin Ferrey (1810-1880) who studied alongside Augustus Welby Pugin, famous for his work on The Houses of Parliament. The Church was built at the height of the period of Victorian church building and is clearly influenced by the Oxford Movement in its focus on sacrament and the artistic expression of the transcendent nature of God.

The chancel wall paintings are a fine example of this Neo-Gothic style and have been lovingly restored by the former incumbent,

Fr. Peter Abrahams. The Stations of the Cross, other art work and the Quiet Garden are also part of the creative legacy left by Peter.

The stained glass in the sanctuary is from 1884 and is the work of Charles Kempe (1837 – 1907) one of the leading Victorian stained-glass designers. The main east window is in three lights representing the Nativity, the Shepherds, and the Wise men. It is dedicated to Henry Hutton who died in 1882. The South and North windows of the chancel depict various saints; Elizabeth with John  the Baptist as a boy, John the Evangelist, Stephen, Hugh of Lincoln, Edward Confessor and George. 

The windows in the South Aisle, which were relocated from the North Aisle in 1998, show scenes from the life of Christ; Little Children, the Well at Samaria, Blind Bartimeus and the Pool of Siloam.

They are the work of James Powell & Sons, perhaps Britain’s longest running and most productive glass ‘house’.

The memorial chapel in the North Aisle was given in 1935 by the Royal British Legion. The Roll of Honour for the First World War is inscribed on a pillar to the right-hand side of the altar, and for the Second World War on a plaque on the North Wall. 

The large vicarage was built by the well-known architect G E Street and was occupied from 1852 by the first Vicar of Colnbrook, Charles Dashwood Goldie. By 1978 this house was no longer considered suitable and a new vicarage was built. The old vicarage remained empty for a number of years but following a fire has now been converted in to private dwellings. The large walled garden, now Quiet Garden, and attached glebe land was intended to support the vicar and his family in addition to his small income.

The Church School and School House were built from 1868, again by G E Street, and were used as a school until the Colnbrook C of E Primary School was built in the 1970s. The Old School opened as a Sure Start Children’s Centre in 2011 but is now closed.
