Slough's population is one of the most ethnically diverse in the United Kingdom,[4][5] attracting people from across the country and the world for labour since the 1920s, which has helped shape it into a major trading centre. As of the 2021 UK census, 46.9% of the population wasAsian, 35.9%White, 7.5%Black, 4%Mixed, 1.2%Arab and 4.5% ofother ethnic heritage.[6]

The town's name was first recorded in 1195 asSlo. It first seems to have applied to a hamlet betweenUpton to the east andChalvey to the west, roughly around the "Crown Crossroads" where the road to Windsor (now the A332) met the Great West Road.[11] TheDomesday Survey of 1086 refers to Upton, and a wood for 200 pigs, worth £15. During the 13th century, KingHenry III had a palace at Cippenham. Parts of Upton Court were built in 1325, while St Mary the Virgin Church[12] inLangley was probably built in the late 11th or early 12th century, though it has been rebuilt and enlarged several times.
Seven Grade II*:St Mary's Church (Upton-cum-Chalvey), Upton Court, the Kederminster and Seymour Almshouses in Langley, St Peter's Church (Chalvey), Ostrich Inn (Colnbrook) and King John's Palace (Colnbrook)
Grade II listed structures include four milestones, Beech, Oak and Linden Houses at Upton Hospital,St Ethelbert's Church, Slough and Slough railway station.
The year 1918 saw a large area of agricultural land to the west of Slough developed as an army motor repair depot, used to store and repair huge numbers of motor vehicles coming back from the battlefields of theFirst World War inFlanders. In April 1920, the Government sold the site and its contents to the Slough Trading Co. Ltd. Repair of ex-army vehicles continued until 1925, when the Slough Trading Company Act was passed allowing the company (renamedSlough Estates Ltd) to establish anindustrial estate.[14] Spectacular growth and employment ensued, with Slough attracting workers from many parts of the UK and abroad.Slough Town Hall, which was designed byCharles Holloway James andStephen Rowland Pierce, was completed in 1937.[15]
During theSecond World War, Slough experienced a series ofair raids, mostly in October 1940 (the largest number of people, five, dying as a result of a raid on the 13th), and an emergency hospital treating casualties from London was set up in Slough. Local air raid deaths and deaths at the hospital account for the 23 civilian lives recorded lost in the borough area.[16]
After the war, several further large housing developments arose to take large numbers of people migrating from war-damaged London. Between 1955 and 1957 the town was the site of theSlough experiment, a large-scale road safety trial.[17]
The old Slough library was opened on 28 November 1974. It was officially called the Robert Taylor Library, named after Alderman Taylor in recognition of his contribution to the library service. The library was officially opened by the Mayor, Councillor DR Peters, on 15 May 1975. It was demolished in May 2017 as part of the programme of redevelopment in the town centre.[18]

'The Curve', Slough's distinctively shaped Library and Cultural Centre, opened in 2016. It was named 'Best public service building' at the Local Authority Building Control (LABC) excellence awards held in March 2017. It was built by Slough Urban Renewal, a partnership between the council and Morgan Sindall.

In the 21st century, Slough has seen major redevelopment of the town centre. Old buildings are being replaced with new offices and shopping complexes.Tesco has replaced an existing superstore with a largerTesco Extra. TheHeart of Slough Project is plan for the large-scale redevelopment of the town centre as a focus and cultural quarter for the creative media, information and communications industries created a mixed-use complex, multi-functional buildings, visual landmarks and a public space in theThames Valley.[19] Approval was given for the £400 million project by Slough Borough Council's planning committee on 9 July 2009,[20] and work began in 2010 for completion in 2018.[21]
In December 2009, two key components of the project were signed: the Homes and Communities Agency (HCA) signed its agreement to provide £11m of funding for infrastructure and Thames Valley University (TVU) courses which were due to remain in the town found a new home at the Centre in Farnham Road, Slough.[22] In parallel to the town centre redevelopment plan,Segro (owner of the Slough Trading Estate) planned to spend £600 million over the following 20 years on the estate. This was intended to create environmentally sustainable buildings, open green spaces, two hotels, a conference centre, cafés, restaurants and better transport facilities to improve links to Slough town centre and the surrounding residential areas. It was claimed that the plan would create more than 4,100 new jobs and contribute around £100m a year to Slough's economy.[23] If both plans went ahead, nearly £1 billion would be spent on redeveloping Slough over the next 20 years.
In 2010, £2 million was set aside to improve disabled access to Slough railway station in preparation for an expected increase in use during the 2012 London Olympics.[26] Preparations were under way for the regeneration of the Britwell suburb of Slough, involving tearing down a dilapidated block of flats and the closing of the public house the Jolly Londoner in Wentworth Avenue and replacing them with new homes, as well as relocating the shopping parade in the street to nearby Kennedy Park.[27]
As part of the Heart of Slough project, construction work ona new bus station began in March 2010, following weeks of demolition work to half of the existing bus station and the removal of Compair House near the railway station.[10][28] It was opened in May 2011.
Redevelopment on this scale has been strongly criticised by conservation groups.The Twentieth Century Society has stated that
[A] tragically high quantity of good buildings have been demolished in Slough in recent years, including grand Art-Deco-styled factories by the likes of Wallis Gilbert and high-quality post-war offices. More are to come down as the town tries to erase its past and reinvent itself from scratch. Despite famously heckling Slough,John Betjeman's praise for the town hall's architecture as 'a striving for unity out of chaos' in 1948 has never been so relevant as today. C20 believes that the redevelopment of the town hall would be an act of vandalism to the civic centre and is supporting the Campaign to Save Slough's Heritage in their request for a review of the decision.[29]
During November 2016, the Slough Queensmere and Observatory shopping centres were sold toAbu Dhabi Investment Authority (ADIA) in a deal worth £130 million.[30]
In February 2025, it was reported that the council was considering a number of options to merge with larger local authorities, including joining a London borough or becoming part of theGreater London Authority.[31]
Most of the area that now makes up Slough wasanciently part ofBuckinghamshire, however, Poyle was historically in Middlesex. The town developed by the expansion and amalgamation of villages along theGreat West Road. Over the years Slough has expanded greatly, incorporating a number of different villages. Original villages that are now suburbs of Slough includeChalvey,Cippenham,Colnbrook,Langley,Poyle,Upton, andWexham.
The nearestMet Office weather observing station to Slough isHeathrow Airport, about 5 miles (8 km) east of Slough town centre. This part of theThames Valley is notable for generally having the warmest daytime summer temperatures on average in theBritish Isles.[citation needed] Typically, according to 1981–2010 normals, the average high temperature in July is 23.5 °C (74.3 °F.)
Rainfall is low compared to most of the British Isles, with under 600 mm (23.62 in) annually, and 105 days[32] reporting over 1 mm of rain.
According to the2021 census, Slough is a large town with a population of 158,400 of which 46.9% of the population wasAsian, 35.9%White, 7.5%Black, 4%Mixed, 1.2%Arab and 4.5% of other ethnic heritage.[6] This makes the town one of the most ethnically diverse local authorities in the country outside of London.
Despite its diverse population, English is the most spoken language in 2021, with over 110,212 citing English as their first language. Those stating other languages is significantly lower due to the large shares of theBritish Asian andBlack population speaking English as their first language. Aside from English, the most commonly spoken languages arePunjabi,Polish, andUrdu.[37]
Figures from the2021 UK census showed that 32% of Slough's population identified asChristian, 29.4% asMuslim, 11.4% asSikh, 7.8% asHindu, 0.5% asBuddhist, 0.1% asJewish, 0.5% as having other religions, 13% as havingno religion and 5.4% did not answer the question.[38]
Compared with the2011 UK census, the percentage of Slough residents identifying as Muslim increased by 6.1%, the largest increase of any religious group in Slough, while those identifying as Christian fell from 41.2% to 32.0%, with those identifying as having no religion rising slightly from 12.1% to 13.1%.[38]
Slough was historically a hamlet in the parish ofUpton, also known as Upton-cum-Chalvey, inBuckinghamshire.[40] Until 1863 it was administered by the parishvestry andmanorial courts, in the same way as most rural areas. As Slough began developing into a town, the need for more urban forms of local government grew. In 1863 alocal government district was established for Slough, covering part of the parish of Upton-cum-Chalvey (including the old village of Upton) and a smaller part of the neighbouring parish ofStoke Poges. The town was then governed by an elected local board.[41]
Such local government districts were converted intourban districts under theLocal Government Act 1894.[42] In 1900 the Slough urban district was enlarged to absorb most of the residual parts of the old Upton-cum-Chalvey parish that had been outside the urban district, includingChalvey. The urban district was further enlarged in 1930, when it was significantly expanded to take in most of the neighbouring parish ofLangley (including the village), theSalt Hill area from the parish ofFarnham Royal, and theCippenham area from the parish ofBurnham. In 1938 the urban district was incorporated to become amunicipal borough.[43]
In 1998 Slough Borough Council became a unitary authority whenBerkshire County Council was abolished and the borough council took on the former county council's functions in the borough.[46]
Since 2015, Slough has had a Youth Parliament to represent the views of younger people.
Slough Trading Estate played a major part in making Slough an important business centre in South East England.

Slough Retail Park, one of many large outlets in the town
Before the 19th century, the main businesses of Slough were brickfields and agriculture. The bricks for the building ofEton College were made in Slough. Later, as theGreat West Road traffic increased, inns and pubs sprang up along the road to service the passing trade. Until the town developed as an industrial area,nurseries were prominent in the local economy; theCox's Orange Pippin apple was first raised in Colnbrook (not then within Slough) around 1825, and thedianthus "Mrs Sinkins Pink" was first raised at some point between 1868[48] and 1883[49] by John Sinkins, the master of theEtonUnionWorkhouse,[50] which lay in Slough.
In the mid-19th century, the only major employer apart from the brickfields wasJames Elliman, who started as a draper in Chandos Street. In 1847, he changed business and manufactured his Elliman's Embrocation and Royal Embrocation horseliniment at factories in Wellington Street and Chandos Street. Elliman became a major benefactor to the town, and is remembered today in the names of local roads and schools.
In September 1851,William Thomas Buckland, anauctioneer andsurveyor from nearbyWraysbury, began livestock sales in a field near the Great Western Road Railway Station belonging to the North Star Inn. Originally held on the first Tuesday of every month, the Cattle Market's popularity soon saw this increased to every Tuesday. A move to Wexham Street was necessitated by the postwar redevelopment of the town. The Slough Cattle Market was run by Messrs Buckland and Sons until its final closure in 1988.[51]
In 1906,James Horlick, one of the founders of the eponymousmalted milk company, opened a purpose-built red-brick factory near Slough Railway Station to manufacture his malted milk product. In 2015, the business was sold byGlaxo Smith Kline and in 2017, manufacturing at the site ceased altogether. The site is currently proposed to become residential making use of the original buildings as much as possible.
Starting in the 1920s,Slough Estates Ltd, the operator of the originalSlough Trading Estate, created and operated many more estates in the UK and abroad. The Slough Trading Estate meant that the town was largely insulated from many of the effects ofrecession. For many years, Slough's economy was mainly manufacturing-based. The company Zwicky Limited, a manufacturer of liquid pumps, filters, compression valves and aircraft refuelling units, runway sweepers were based in Slough.[52][53][54]
In the last 20 or so years,[when?] there has been a major shift from a manufacturing to an information-based economy, with the closure of many factories (some of which had been in Slough for many decades). The factories are rapidly being replaced by office buildings. Hundreds of major companies have sited in Slough Trading Estate over the years, with its proximity to LondonHeathrow Airport and good motorway connections being attractive. In the 1960s,Gerry Anderson's film company was based in Slough, and hisSupermarionation series, includingThunderbirds, were filmed there.[55]
The motor trade has long been represented in Slough. Until 1966,Citroën assembled cars in a Liverpool Road factory (later used by Mars Confectionery), and it retains its UK headquarters in the town.Ford builtD Series andCargo lorries at its factory in Langley (a formerHawker Aircraft site) from 1936 to the 1950s[58] until the site was redeveloped for housing in the 1990s.Ferrari,Mercedes,Fiat andMaserati now have offices in the town.

Slough is connected by theSlough Arm to the main line of theGrand Union Canal which runs between the Thames at Brentford and Birmingham. It travels from the terminus basin at Stoke Road to the junction with the main line at Cowley Peachey; it was restored to navigability in 1975 having been disused since 1960.[73]
There are numerous primary and secondary schools serving Slough. Of the latter there are fourstategrammar schools. In addition,East Berkshire College has a campus in the area. Slough schools are in the top 10 best performers in the country at GCSE level. In 2011, 68.1% of pupils left school with a minimum of 5 A*-C grades (with English and maths). The national average is 58.9%.[82]
Thames Valley University (Slough Campus) is currently closed due to theHeart of Slough project. The new campus was scheduled to be opened in 2013 as part of theUniversity of West London, but as of March 2022 there had been no progress, as the former site of the university had been sold for housing.
1932: (but set in the 26th century) InAldous Huxley'sBrave New World, the chimneys of Slough Crematorium, around whichBernard Marx flies, are used to demonstrate the physio-chemical equality of all people.[84] (Slough's actual crematorium, in the cemetery in Stoke Road, was opened in 1963,[85] coincidentally the year of Huxley's death.Princess Margaret was cremated there in 2002.)[86][87]
1937: The poetJohn Betjeman wrote his poemSlough as a protest against the new town and 850 factories that had arisen in what had been formerly a rural area, which he considered an onslaught on the rural lifestyle:
Come, friendly bombs and fall on Slough
It isn't fit for humans now
There isn't grass to graze a cow.
Swarm over, death!
The poem was published two years before the outbreak of the Second World War, in which Britain (including Slough itself) experienced bombing from enemy air raids. On the centenary of his birth, his daughter said her father "regretted having ever written it", presenting the Mayor David MacIsaac with a book of his poems in which she had written: "We love Slough".[88]

1996: TheTiger Lillies' albumThe Brothel to the Cemetery includes a track called "Slough", probably inspired by Betjeman's poem. The lyrics to the chorus are:
Drop a bomb on Slough, Drop a bomb on Slough
Drop a bomb on Slough, Drop a bomb on Slough
1998: The song "Costa del Slough" by the rock bandMarillion posits the town as a post-global warming coastal resort, possibly in a reference to the comedianSpike Milligan having presented Slough on TV as a holiday resort.
2001: TheBBC comedy seriesThe Office was set in the sales office of a paper company in Slough, presenting it as a depressing post-industrial wasteland.

2010-2025: In theSlough House novels byMick Herron and the adapted Apple+ TV seriesSlow Horses, Slough House is the MI5 branch where washed-up spies are sent to finish their failed careers on desk duty. The name derives from the fact that, as Slough is distant from London, similarly Slough House is equally far away from the headquarters of MI5 in Regents Park for the disgraced spies hoping to revive their careers.
2015: TheSky One comedy drama seriesYou, Me and the Apocalypse is set in Slough, where a nuclear bunker is located underneath the Slough Trading Estate. Aerial views are seen of Slough throughout the series.

Anyone could put you down
Crime
Slough has a relatively high crime rate; figures for all crime categories are annually above the English average and figures for a few categories are at more than double the frequency.[89] According toBritish Crime Survey statistics, as of September 2013, Slough had the second worst rate of crime among local authority areas in the Thames Valley Police counties (87 recorded crimes per 1,000 population vs Oxford's 104).[90] However the borough's crime rate reduced by 29% in the ten years to 2013.[91] In the year ending September 2017, the crime rate in Slough was the third highest in the Thames Valley force area, behind Reading (96.42 police recorded crimes per 1000 population) and Oxford (100.71 for the same metric).[90]
