The house was built between 1814-1817 when the earliest reference to it was recorded. At this time, it is likely that the house was built within the boundary of the Parish of Warfield whilst the grounds of the estate fell within the Parish of Winkfield. The entrance to the estate was by way of a gated road from The Lodge, now situated on the main road to Ascot, London Road. The original driveway up to the house extended for half a mile. In 1817, parish records advise that Henry Dormer Vincent became the owner and lived in the house until his death in 1833. He was the son of Sir F Vincent 7th Bart and MP for Surrey.

Henry Dormer Vincent married Isabella, daughter of the Hon. Felton Harvey and had two sons, Henry William born 1796 and Fredrick born 1798. Henry William Dormer Vincent was responsible for further extensions to the house between 1849-1858. He was the landowner and occupier of about 88 acres. He leased a further 11 acres and additional properties for which the Tithe was £8.16.0d.

Henry William Vincent lived in Lily Hill House after his parents died. Records show that he was educated locally, at Eton. He was Clerk to the Treasury from 1813-1823, Private Secretary to the Earl of Liverpool from 1823-1858, Queens Remembrancer in the Exchequer and was called to the Bar in 1850.

He later became Deputy Lieutenant for the Forestry Division of Berkshire and a Magistrate for Middlesex (where he also had a second house) and was also a member of the Travellers Club.
In 1830, he married Elizabeth Anne Callander of Craigforth and Arkinlas. They had three daughters, the elder Mary died young, Susan Ann born in November 1832 and Harriet born in 1834. Henry’s wife Elizabeth died in 1839.  Henry William Vincent took an active interest in the affairs of Bracknell Forest Church and when he died in 1865, he was buried in the nearby local church.

Henry’s daughter Susan Ann married John Bagot Lane who was formerly a Lieutenant Colonel in the Coldstream Guards and who sold his commission in 1867. He became a Magistrate for the Forest Division of Berkshire. They had three sons John, Arthur and George and four daughters Agnes, Florence, Constance and Lilian. Lieutenant Colonel Lane died in March 1886 aged 56 and his widow continued to live at Lily Hill House until she died in October 1899.

The main alter window in Bracknell Parish Church is a memorial to Lieutenant Colonel Lane whilst the window of the Presentation of the Temple situated in the Lady Chapel is in memory of Mrs Susan Lane,

In 1902 Charles Neck purchased the property from John Henry Harvey Vincent Lane. After only a short occupation, Mr Neck died in St. Remo in 1904.  Charles Neck left a widow and four sons Philip, Stephen, Charles and Clarence and three daughters. Mrs Grace Emily Gorton Neck continued to live in Lily Hill House until 1911.

Tragedy then struck the family. Within a week of each other, two sons were killed in the First World War. Charles, Lieutenant Northumberland Fusiliers aged 21 and Philip, Lieutenants Grenadier Guards aged 27 both died in October 1914. The window in the north aisle of Bracknell Parish Church is in memory of the two brothers.

In 1912, Jennings Scott McComb purchased Lily Hill House and after his death in 1928 his widow Mary (nee Gilkinson) continued to live there until 1955 when the house and estate was sold to Bracknell Development Corporation and Mary McComb moved from the area.

The house was eventually converted for business use and has been a home to a number of different companies over the years (Racal, Ferranti to name a couple).  In 1981, a development was allowed to form 10,000 sq. ft. of offices which was linked to the Manor House by a corridor walkway.  From around 1990, Lily Hill House remained vacant and became dilapidated with the majority of the roof to the main house being removed. The fabric of the main building was extensively damaged during this period.

In 2000, Lily Hill House was acquired as an investment property and extensively modernised, providing a contemporary feel yet retaining the charm and character of the original house. The atrium and new offices to the rear of the house were added. The link corridor was removed and a roadway linking the carpark was added.

In 2001, Bracknell Forest Borough Council began a restoration programme of Lily Hill Park with a lottery grant of £113,000 to rejuvenate the once lovely grounds and woodland to their former glory.  The immediate grounds of Lily Hill House were replanted and restored to an equal standard, including the planting of the rhododendron beds and natural meadowland to the West of the house. 

In 2010, Oxford Innovation was employed to manage the building as a business centre, letting the building to a number of occupiers, rather than just one.  It is now home to a wide variety of companies and the history of the house continues to develop.
