Sleaford is a market town and civil parish in the North Kesteven district of Lincolnshire, England. On the edge of the Fenlands, it is north-east of Grantham, west of Boston, and south of Lincoln. It is the largest settlement in North Kesteven with a population of 19,807 in 2021. Centred on the former parish of New Sleaford, the modern boundaries and urban area include Quarrington to the south-west, Holdingham to the north-west and Old Sleaford to the east. The town is bypassed by the A17 and the A15 roads. Sleaford railway station is on the Nottingham to Skegness (via Grantham) and Peterborough to Lincoln lines.
The first settlement formed in the Iron Age where a prehistoric track crossed the River Slea. It was likely home to a mint for the Corieltauvi in the 1st centuries BC and AD. Evidence of Roman and Anglo-Saxon settlement has been found. Medieval records differentiate between Old and New Sleaford, the latter emerging by the 12th century around the present-day market place and St Denys' Church; Sleaford Castle was also built at that time for the Bishops of Lincoln, who owned the manor. Granted the right to hold a market in the mid-12th century, New Sleaford developed into a market town and became locally important in the wool trade, while Old Sleaford (based near the site of the prehistoric settlement) declined.
From the 16th century, the landowning Carre family kept tight control over the town – it grew little in the early modern period. The manor passed by marriage to the Hervey family (Earls and later Marquesses of Bristol) in 1688. The town's common lands were enclosed by 1794, giving ownership mostly to the Herveys. This coincided with canalisation of the Slea, which brought economic growth until it was superseded by the railways in the mid-1850s. These new transport links supported the development of light industries and expanded the town's role in the trade in agricultural goods. Long a centre for justice and administration in north Kesteven, Sleaford became an urban district in 1894 and was home to Kesteven County Council's offices from 1925 to 1974. After a period of stagnation, in the late 20th and early 21st centuries the sale of farmland around Sleaford led to the development of large housing estates, causing the population to rapidly expand and the urban area to engulf Quarrington and Holdingham.
Though its traditional market has declined in the 21st century (and its cattle and corn markets shut in the 20th century) and much of its heavier manufacturing has departed, Sleaford's economy has diversified. The town remains an important administrative, service and commercial centre for the surrounding district. It houses supermarkets, shops and a large business park with offices and light manufacturing; the headquarters of North Kesteven District Council; three secondary schools (two of which are selective); four primary schools; three newspapers; police, fire and ambulance stations; several places of worship; many sports clubs; a leisure centre; and several medical and dental practices and care homes. Regeneration has transformed some earlier industrial areas, including through the construction of The Hub. The town is one of the largest employment centres in the district; the commonest employers in 2021 were the public sector, retail and, to a much lesser degree, manufacturing.
Geography
Sleaford is a civil parish and market town in the North Kesteven district of Lincolnshire. It is bounded by the civil parishes of Leasingham to the north; Ewerby and Evedon, and Kirkby la Thorpe to the east; Silk Willoughby to the south; and Wilsford, South Rauceby and North Rauceby to the west. These neighbouring parishes are rural, comprising villages separated from Sleaford's urban area by fields, though Kirkby la Thorpe also includes the Milton Way housing estate on Sleaford's eastern fringe.
Urban area
Sleaford's urban area includes the town centre, focused on the marketplace (fronted by St Denys' Church), where Eastgate, Northgate, Southgate and Westgate meet. Though some parts have been redeveloped in the 20th century, including the Riverside Shopping Precinct and Flaxwell House, the area follows a medieval street layout and is home to many of the town's oldest buildings; it is also the retail and commercial hub. Carre Street (running parallel to Southgate to the east), once home to industry and wharves, has been regenerated in the late 20th and early 21st centuries. To the town's north-east, the built-up area has expanded along Eastgate, where 19th-century housing closer to the town centre gives way to modern business parks; the River Slea forms the southern boundary of these developments and, closer to the town, Lollycocks Field sits between one of the business parks, Eastgate and the Slea.
The Victorian train station can be found near the southernmost end of Southgate; Station Road includes some converted 19th-century warehouses. Mareham Lane heads south out of the town, past the vast disused Bass Maltings complex. Also forking off from Southgate are Grantham Road and London Road, which fan out in a south-west direction. They link Sleaford with Quarrington village, Ribbon development along London and Grantham roads is mostly early-20th-century; much larger planned developments took place in the late 20th and 21st centuries at Quarrington Hill, Southfields and between the two roads. to its north is Westholme, parkland which houses a school; south of Westgate is West Banks and its adjoining streets, between the River Slea and the Nine-Foot Drain, an area heavily built up in the 19th century. South of Westbanks are the remains of Sleaford Castle.
Topography and geology
Sleaford occupies a position on the Lincoln Heath, a limestone plateau between the Lincoln Cliff to the west (a Limestone scarp running north–south through Lindsey and Kesteven), and the Fens to the east, a low-lying region of the East of England which has been drained to reveal nutrient-rich soils that form some of the most productive farmland in the country.
The town centre lies about above sea level and has formed around the River Slea, which runs west to north-east through it. A band of Jurassic Cornbrash limestone forms the bedrock under Holdingham (where the ground rises to above sea level in places), parts of central Sleaford, and most of the housing at Quarrington (where elevations exceed over at Quarrington Hill) and southern Greylees. The bedrock on the eastern parts of the town comprises Jurassic Kellaways sandstone and siltstone. To the west, the Slea follows a shallow valley underlain by Jurassic Blisworth clay and limestone and, at its lowest elevations at Quarrington Fen and Boiling Wells Farm, earlier Jurassic Rutland argillaceous rocks and Upper Lincolnshire limestone. Greylees and the northern fringe of the Quarrington Hill estate sit on the southern edge of this valley, on the Blisworth clays and limestone. Alluvium deposits are found along the Slea's course, and sand and gravel of the Sleaford series are found to the east and south.
Two Local Nature Reserves sit within the civil parish boundaries: Lollycocks Field, providing mostly wildflower and wetlands habitats alongside Eastgate, and Mareham Pastures, consisting of wildflower meadows, new woodland, hedges and open grassland. There is also Sleaford Wood in the north of the town and Sleaford Moor to the north-east, near the A17 and A153's Bone Mill Junction. Lincolnshire's position on the east of the British Isles allows for a sunnier and warmer climate relative to the national average, and it is one of the driest counties in the UK. In Sleaford, the average daily high temperature peaks at in July and a peak average daily mean of occurs in July. The lowest daily mean temperature is in January; the average daily high for that month is and the daily low is (the latter also occurs in February). Sleaford suffered them in 2006 and 2012.
History
Etymology
The earliest records of the place-name Sleaford are found in a charter of 852 as Slioford and in the Anglo-Saxon Chronicle as Sliowaford. In the Domesday Book (1086), it is recorded as Eslaforde and in the early 13th century as Sliforde. The name is formed from the Old English words and , together meaning "ford over a muddy or slimy river".
Early period
thumbnail|An electrum [[stater of the Corieltauvi, probably struck at Sleaford in the mid-1st century BC]]
Archaeological material from the Bronze Age and earlier has been recovered and excavations have shown there was unsustained late-Neolithic and Bronze Age human activity in the vicinity. The earliest known permanent settlement dates from the Iron Age, where a track northwards from Bourne crossed the River Slea. Although only sparse pottery evidence has been found for the middle Iron Age period, 4,290 pellet mould fragments, probably used for minting and dated to 50 BC–AD 50, have been uncovered south-east of the modern town centre, south of a crossing of the River Slea and near Mareham Lane in Old Sleaford. The largest of its kind in Europe, the deposit has led archaeologists to consider that the site in Old Sleaford was one of the largest Corieltauvian settlements in the period and possibly a tribal centre.
During the Roman occupation of Britain (AD 43–409), the settlement was "extensive and of considerable importance". It may have been an economic and administrative centre for stewards and owners of fenland estates. There are signs of a road connecting Old Sleaford to Heckington, where Roman tile kilns have been uncovered and may imply the presence of a market. When the first roads were built by the Romans, Sleaford was bypassed as "less conveniently located" and more "geared to native needs". A smaller road, Mareham Lane, which the Romans renewed, ran through Old Sleaford, and south along the fen edge towards Bourne. Where it passed through Old Sleaford, excavations have shown a large Roman domestic residence, associated farm buildings and field systems, and several burials. Other Roman remains, including a burial, have been excavated.
Middle Ages
thumb|A plan of [[Sleaford Castle|350x350px]]
There is little evidence of continuous settlement between the late Roman and Anglo-Saxon periods but the Saxons did establish themselves eventually. South of the modern town, a 6th- to 7th-century cemetery has been uncovered with an estimated 600 burials, many showing signs of pagan rites. The now-ruined church at Old Sleaford has been discovered
The earliest documentary reference to Sleaford occurs in a 9th-century charter, when it was owned by Medehamstede Abbey in Peterborough, a Mercian royal foundation. There is little evidence of estate structure until the late Saxon period, The Slea played a big part in the town's economy: it never ran dry or froze, and by the 11th century it supported a dozen watermills. The mills and others in nearby Quarrington and the lost hamlet of Millsthorpe formed the "most important mill cluster in Lincolnshire".
In the later Middle Ages, the Romano-British settlement became known as Old Sleaford, while New Sleaford was a settlement centred on St Denys' Church and the market place. The Domesday Book of 1086 has two entries under Eslaforde (Sleaford) recording land held by Ramsey Abbey and the Bishop of Lincoln. a development associated with the construction of Sleaford Castle (1123–39). who have reinterpreted the Domesday material and argued that in 1086 the Bishop's manor included the church and associated settlement which became "New" Sleaford.
A charter to hold a fair on the feast day of St Denis was granted by King Stephen to Alexander, Bishop of Lincoln, in 1136–1140. Between 1154 and 1165, Henry II granted the bishop of Lincoln the right to hold a market at Sleaford and Edward III confirmed this in 1329. The town later had at least two guilds comparable to those found in developed towns. However, there was no formal charter outlining the town's freedoms; tight control by the bishops meant the economy was mainly geared to serve them. It thus retained a strong tradition of demesne farming well into the 14th century. A survey of burgage tenure from 1258 survives, analysis of which indicates that demesne farming centred on the hamlet of Holdingham. As the economic initiative passed more to burgesses and middlemen who formed ties with nearby towns such as Boston, evidence suggests that Sleaford developed a locally important role in the wool trade. In the Lay Subsidy of 1334, New Sleaford was the wealthiest settlement in the Flaxwell wapentake, with a value of £16 0s. 8<sup>1</sup>/<sub>4</sub>d. Meanwhile, Old Sleaford, an "insignificant" place since the end of the Roman period, declined and may have been deserted by the 16th century.
Early modern period
thumb|The tomb of Sir Edward Carre (died 1618) in St Denys' Church
The manor of Old Sleaford was owned in the late 15th and early 16th centuries by the Hussey family. John Hussey, 1st Baron Hussey of Sleaford was executed for treason for his part in the Lincolnshire Rising; the manor and his residence at Old Place reverted to the Crown and were later sold to Robert Carre, the son of George Carre or Carr, a wool merchant originally from Northumberland who had settled in Sleaford by 1522. Robert also bought the castle and manor of New Sleaford from Edward Clinton, 1st Earl of Lincoln. His eldest surviving son Robert founded Carre's Grammar School in 1604, and his youngest son Edward was created a baronet; his son founded Sleaford Hospital in 1636. The last male descendant died in 1683 and the heiress, Isabella, married John Hervey, 1st Earl of Bristol, in whose family the estates remained until the 1970s. The Carres and Herveys had a strong influence: while extracting dues from their tenants, they enforced their monopoly on charging tolls on market and cattle traders and for driving animals through the town.
Industry was slow to take hold. By the second half of the 18th century, Cogglesford Mill was the only working corn mill in the town. An old mill at the junction of Westgate and Castle Causeway supplied hemp to the rope-making business of the Foster and Hill families. As the local historian Simon Pawley wrote, "In many respects, things had changed little [by 1783] since the survey of 1692," with few of the buildings or infrastructure being improved. Major changes to agriculture and industry took place in the last decade of that century. Sleaford's three medieval open fields (North, West and Sleaford Fields) were enclosed in 1794, with over 90 per cent of the of the open land being granted to Lord Bristol.
Industrial development

Canalisation of the Slea culminated in the opening of the Sleaford Navigation in 1794. It eased the export of farm produce to the Midlands and the import of coal and oil. Mills along the Slea benefited and wharves were constructed around Carre Street. Between 1829 and 1836 the navigation's toll rights increased in value 27 times over. The railways emerged in the 19th century as an alternative to canals and arrived at the town in 1857, when a line from Grantham to Sleaford opened. This made trading easier and improved communications, leading to the decline of the Navigation Company whose income from tolls decreased by 80 per cent between 1858 and 1868; it became unprofitable and was abandoned in 1878. The town's rural location and transport links led in the late 19th century to the rise of two local seed merchants: Hubbard and Phillips, and Charles Sharpe; the former took over the Navigation Wharves, and the latter was trading in the US and Europe by the 1880s. The advent of steam power led Kirk and Parry to open a large steam-powered flour mill in 1857 and provided the basis of Ward and Dale's factory, which made steam cultivators for farming. The railway, Sleaford's rural location and its artesian wells, were key factors in the development of the Bass & Co maltings complex at Mareham Lane (1892–1905). Coinciding with this is the construction or extension of public buildings, often by the local contractors Charles Kirk and Thomas Parry. The gasworks opened in 1839 to provide lighting in the town. Sleaford's Poor Law Union was formed in 1836 to cater for the town and the surrounding 54 parishes. A workhouse was built by 1838, able to house 181 inmates. Despite these advances, the slums around Westgate were crowded, lacking in sanitation and ridden by disease; The local administration failed to deal with these issues, prompting a heavily critical report by the General Board of Health, which set up a Local Board of Health in 1850 to undertake public works. By the 1880s, Lord Bristol had allowed the Board to pump clean water into the town, though engineering problems and his reluctance to sell land to house a pumping station had delayed the introduction of sewers. In the meantime, despite Anglicans dominating official institutions, non-conformist chapels were flourishing in the poorest parts of the town, at Westgate from the early 19th century and at Northgate after 1848, where they sought to provide spiritual care and education. Temperance was so prominent in the town that an aerated water factory, Lee and Green, opened in c. 1883 and became one of Sleaford's most important manufacturers.
Twentieth century and beyond
thumb|Officer Training School at [[RAF Cranwell, near Sleaford.]]
Although hardly damaged in the First and Second World Wars, Sleaford has close links with the Royal Air Force due to proximity to several RAF bases, including RAF Cranwell, RAF Digby and RAF Waddington. Lincolnshire's topography – flat and open countryside – and its location in the east of the country made it ideal for the airfields being constructed in the First World War. Work began on Cranwell in late 1915; it was designated an RAF base in 1918 and the RAF College opened in 1920 as the world's first air academy. The Cranwell branch railway linking Sleaford station with the RAF base opened in 1917 and closed in 1956. During the Second World War, Lincolnshire was "the most significant location for bomber command" and Rauceby Hospital, south-west of Sleaford, was requisitioned by the RAF as a specialist burns unit which the plastic surgeon Archibald McIndoe regularly visited. In the post-war period, there were housing developments at St Giles Avenue, the Hoplands, Russell Crescent, Jubilee Grove and Grantham Road. Parts of the town were redeveloped: in 1958, the Bristol Arms Arcade opened, the Corn Exchange was demolished in the 1960s and the Riverside Shopping Precinct opened in 1973, as did Flaxwell House, designed to house a department store, though later becoming the national headquarters for Interflora. Old industries departed; Ward and Dale closed down in 1939 and Lee and Green around the 1940s; Bass shut the maltings in 1959, and Hubbard and Phillips's pea-sorting factory closed in 1972.
By 1979, the major landowner, Victor Hervey, 6th Marquess of Bristol, was heavily in debt and sold most of his estates in Sleaford and Quarrington. The estate office closed in 1989. Much of the land went to property developers and subsequent decades brought new housing and a considerable rise in population. According to a council report, people were attracted to the town by "the quality of life, low crime rates, relatively low house prices and good-quality education". From 1981 to 2011, Sleaford's population more than doubled; the growth rate in 1991–2001 was the fastest of any town in the county. The infrastructure struggled to cope, especially with increased traffic congestion. Two bypasses opened and a one-way system was introduced.
Economy
The Sleaford built-up area is the urban centre of the North Kesteven district, and one of the district's centres of employment. According to a local authority report, Sleaford is also "the main retail, service and employment centre for people living in the town and in the surrounding villages". The town's primary employment zones are Sleaford Enterprise Park, the adjoining business park at Woodbridge Road and along East Road, and the town centre (focused on Southgate, Northgate and the Market Place). Many of North Kesteven's residents also commute out of the district to work, including to Lincoln, Grantham and Newark-on-Trent;
Retail and services
Sleaford is a retail and services hub for its own population and its rural hinterland. In 2021, retail, accommodation and food services made up 21% of the town's workforce. including those in the covered Bristol Arcade (opened in 1958) and the Riverside Centre (opened in 1973). Other retailers and wholesalers operate on East Road and the business parks. as of 2025 it continues to be held weekly on Fridays, Saturdays and Mondays, and a farmers' market is held on the first Saturday of each month.
In 2011, the district council found that Sleaford's retail and service offer had not kept pace with its growing population, leading many shoppers to travel elsewhere to buy high-value goods, use services or engage in leisure activities: 85p in every pound spent on higher-value comparison goods were spent outside of the town. In 2015, another report estimated that 23% of shopping spend in Sleaford's catchment area was spent in the town (accounting for £62m spending); although the town had 210 shops and a higher ratio of shops to residents than many other urban areas in the region, these were dominated by outlets selling convenience goods and services. The ratio of "multiple" brand shops compared to independent shops was 20% lower in Sleaford compared with regional benchmarks, which was thought to be a factor driving consumer spending out of the town; Lincoln was believed to be the key beneficiary of this outflow. To address this, the district council proposed creating a new "retail anchor" at the disused Bass Maltings, improving parking, removing parts of the one-way system, and regenerating Southgate and Money's Yard. Though the maltings project stalled after an investor withdrew in 2015, the Riverside Centre was refurbished in 2017 and town centre regeneration continues as of 2024.
Public administration
As local government expanded in the late 19th and 20th centuries and RAF Cranwell opened, the public sector became increasingly important to Sleaford's economy. From the early 20th century, the town housed the headquarters of Kesteven County Council, East Kesteven Rural District Council and the town's Urban District Council. By 1939, 18% of its employed population were in public administration and defence. public administration, education and healthcare collectively accounted for 37% of the workforce in 2021. as well as four primary schools and three secondary schools, and is near RAF bases at Cranwell, Digby and Waddington which are major employers in the district. By 2021, manufacturing employed 10% of Sleaford's workforce, construction employed 8.4%, and transport and distribution 6%; the professional, administrative, financial and real estate sectors accounted for a combined 10.6% of the workforce. Combined, in 2024 these estates housed at least 95 businesses, according to Google Maps; these included: 11 wholesalers, builders' merchants or plumbers' merchants; 11 vehicle repair shops or MOT centres; 11 furniture and furnishings shops; 7 manufacturers, including Sleaford Quality Foods (a food producer) and the ingredients' maker, J. L. Priestley and Co; five vehicle dealerships; four plant and equipment suppliers; four tyre shops; two gyms; a dance studio; and a bus company, Sleafordian Coaches.
Demography
Population change
In 1563 there were 145 households in New Sleaford (including 20 in Holdingham), plus 10 in Old Sleaford and 17 in Quarrington. In the late 17th and early 18th centuries, the diocese recorded that there were "more than 250 families" in the ecclesiastical parish of Sleaford, with a further 35 in the parish of Quarrington. One estimate puts the population of New Sleaford at 800 to 900 at this time. The first official census was conducted in 1801 and recorded a population of 1,596 in New Sleaford (including Holdingham); combined with Old Sleaford and Quarrington, this gave a population of 1,812 in the area covered by today's Sleaford civil parish. Following the opening of Sleaford Navigation in 1794 and the flourishing of the town's economy this produced (combined with the effects of inflated agricultural prices during the Napoleonic wars), Sleaford's population rose steadily in the first half of the 19th century. largely due to the fact that Lord Bristol remained owner of the vast majority of the undeveloped land around the town. However, as the 6th Marquess sold the land from the 1960s onwards and speculative housing blossomed around Sleaford, the civil parish's population expanded rapidly; the population growth rate between 1991 and 2001 was the fastest of any town in Lincolnshire. Between 1981 and 2011, the population more than doubled, reaching 17,671; this had risen by a further 12% to 19,815 by the 2021 census. This accounts for 17% of North Kesteven's population, making Sleaford the most populous civil parish in the district.
Ethnicity, nationality and religion
According to the 2021 census, Sleaford's population was 96% White; 1% Asian/British Asian; 1% mixed; and less than 1% Black, African, Caribbean, Black British, or other ethnicities. The population is less ethnically diverse than England as a whole, where 81% were White; 10% Asian/British Asian; 4% Black, African, Caribbean or Black British; 3% mixed; and 2% other. Parish-level data about country of origin have not been published for the 2021 census. The previous census, in 2011, recorded that 93% of Sleaford's population was born in the United Kingdom (in England as a whole the figure was 86%); 4% was born in European Union countries other than the UK and Ireland (England: 4%). 3% of the population was born outside the EU (England: 9%).
The 2021 census also lacks parish-level data on religion. In 2011, 72% of Sleaford's population said they were religious and 23% said they did not follow a religion (England: 68% and 25% respectively). Compared to England's population, Christians were a much higher proportion of Sleaford's population (70%), and all other groups were present at a lower proportion than the national rates; Muslims were the largest religious minority, accounting for 0.4% of the town's residents compared with 5% nationally; all other groups were present in very low numbers.

In 2021, 63% of Sleaford's residents aged 16 to 74 were economically active (England: 61%) and 61% were in employment (England: 57%). The rate of economically inactive people aged 16 to 74 was 37% (England: 39%). The indices divided the Sleaford parish into 10 statistical areas (LSOAs). Of these, five placed in the least-deprived 30% of LSOAs nationally (one in the least-deprived 10% nationally); these were concentrated in Quarrington and the Holdingham ward. However, the eastern part of Holdingham ward and the central parts of the Westholme and Castle wards are among the most-deprived 40% of areas nationally.
Transport
thumb|upright|The [[River Slea in the town was part of the disused Sleaford Navigation canal]]
The A17 road from Newark-on-Trent to King's Lynn bypasses Sleaford from Holdingham Roundabout to Kirkby la Thorpe. It ran through the town until the bypass opened in 1975. The Holdingham roundabout connects the A17 to the A15 road from Peterborough to Scawby. It also passed through Sleaford until 1993, when its bypass was completed. Three roads meet at Sleaford's market place: Northgate (B1518), Southgate and Eastgate (B1517). A one-way system set up in 1994 creates a circuit around the town centre. The bus companies Stagecoach and Sleafordian Coaches operate public buses through and around the town on behalf of the county council, alongside the council's demand-responsive, flexible CallConnect service.
The railways arrived in the 19th century. Early proposals to bring a line to Sleaford failed, but in 1852 plans were made to build the Boston, Sleaford and Midland Counties Railway and its Act of Parliament passed in 1853. The line from Grantham opened in 1857; Boston was connected in 1859, Bourne in 1871 and Ruskington on the Great Northern and Great Eastern Joint Railway in 1882. As of 2024, Sleaford is a stop on the Peterborough to Lincoln Line and the Poacher Line, from Grantham to Skegness. Grantham, roughly by road and two stops on the Poacher Line, is a major stop on the East Coast Main Line. Trains from Grantham to London King's Cross take approximately 1 hour 15 minutes.
Plans to canalise the River Slea were drawn up in 1773, but faced opposition from landowners who feared it might affect fenland drainage. Plans were approved in 1791 with the support of the 5th Duke of Ancaster and Kesteven who owned estates and quarries that he hoped would benefit. An Act of Parliament passed in 1792, establishing the Sleaford Navigation, which opened two years later. Sleaford was in Kesteven and KCC held its meetings alternately in Sleaford and the other major settlement in Kesteven, Grantham.]]
From the medieval period, New Sleaford and Old Sleaford were ancient parishes; New Sleaford contained the main built-up area, and its ancient parish boundaries also included the rural hamlet of Holdingham to the north-west.
Sleaford Poor Law Union, overseen by a Board of Guardians, was founded in 1836 covering Old and New Sleaford and surrounding parishes. The parish of New Sleaford, excluding the hamlet of Holdingham, was made a local board district (LBD) in 1850, governed by an elected local board of health (LBH). Holdingham was made its own civil parish in 1866. The New Sleaford USD was enlarged in 1877 to include Holdingham, Old Sleaford and Quarrington.
The Local Government Act 1894 converted the USD into New Sleaford Urban District, overseen by an urban district council (UDC). In 1900, it was renamed Sleaford Urban District. During a reorganisation of local government, Sleaford Urban District was abolished on 1 April 1974, being absorbed into the new district of North Kesteven. A successor parish called Sleaford was created on 6 July 1973 covering the area of the urban district, which had the effect of abolishing the four parishes of Holdingham, New Sleaford, Old Sleaford and Quarrington. The new parish council declared its parish to be a town at its first meeting on 14 November 1973, allowing it to take the style "town council" and letting the chair of the council take the title of mayor.
Today
thumb|Sleaford is in the North Kesteven District of Lincolnshire (coloured red on this map).There are three tiers of local government covering Sleaford: Sleaford Town Council, North Kesteven District Council and Lincolnshire County Council. County councils have statutory responsibility for some public services, including education, transport, libraries, planning and social care. District councils manage social housing, planning applications, council tax, and waste and recycling. Town councils have powers to run some local amenities. Since the 2023 local elections, the town council has been composed of 18 councillors from five wards. There are seven representatives from five wards on the district council, as of 2023. Sleaford Library has occupied its present building on the Market Place since 1987, having previously been based in the former fire station at Watergate since 1956. As of 2024, the library includes a local and family history section and microfiche machine.
Emergency services and healthcare
Policing is provided by the Lincolnshire Police, firefighting by the Lincolnshire Fire and Rescue Service, and ambulance services by the East Midlands Ambulance Service. The first police station was built at Kesteven Street in 1845 and reconstructed in 1912; the police moved into the former Sleaford Rural District Council offices at the Hoplands on Boston Road in 1998, and this remains Sleaford Police Station as of 2024.
The United Lincolnshire Hospitals NHS Trust provides services at four hospitals: Pilgrim Hospital in Boston, Grantham and District Hospital, Lincoln County Hospital and the County Hospital Louth. As of 2024, Sleaford has two GP surgeries: Sleaford Medical Group and Millview Medical Centre. The town also has three dental surgeries and four pharmacies. Lincolnshire Partnership NHS Trust runs Ash Villa at Greylees for the NHS Mental Health Service. There are also two care homes: Oakdene and Glenholme Holdingham Grange. Between 1902 and 1997, a mental institute, Rauceby Hospital, operated west of Quarrington, initially run by the county council and from 1948 the NHS; its patient enrolment peaked at 590 in 1958. The town had an NHS clinic at Laundon House, which opened as a maternity hospital in the 1930s, was taken over by the NHS in the 1940s and converted to a clinic in the post-war decades, before closing in 2016.
Justice
From the 14th century, justice was administered through the assizes (periodic courts which heard capital cases) or by the justices of the peace (later called magistrates), who tried more serious but non-capital crimes in the quarter sessions with a jury and more minor crimes in the petty sessions without a jury. The petty and quarter sessions came to be known as the magistrates' courts. Other smaller open spaces and playgrounds are managed by the town council.
