Top 10 Windmills in the United Kingdom
England has more surviving working windmills than any other English-speaking country, and its mill heritage is unusually diverse: post mills, smock mills, and tower mills distributed across the flat eastern counties, with isolated survivals in the north and southwest. The SPAB Mills Section has been the primary force in English mill preservation since 1931, training volunteer millers and campaigning for working-mill status as the target of restoration. National Mills Weekend, held on the second weekend of May each year, is the best single opportunity to visit a range of working mills across the country. All the major sites are on the map.
1. Outwood Post Mill, Surrey (1665)
Outwood Mill in Surrey is the oldest working post mill in England, dated to 1665 by documentary record. It is a four-sailed post mill with a full set of original timber machinery inside the buck, which makes it one of the most complete examples of seventeenth-century milling technology still in operation. The mill is owned by the Outwood Mill Society and is open to visitors on weekend afternoons from Easter to October. It grinds on demonstration days. Grade I listed. A twin mill that stood beside it until 1960 is commemorated by a plaque; Outwood is the sole survivor of what was once a pair.
2. Heckington Eight-Sail Windmill, Lincolnshire (1830)
Heckington is the only surviving eight-sail windmill in England. It was built in 1830 as a standard five-sail tower mill and acquired its eight-sail configuration in 1892 when it was fitted with the sail assembly from a demolished Tuxford mill. Eight-sail mills were built in Lincolnshire in the nineteenth century to produce higher power output; all others were reduced to four sails after storm damage. Heckington still grinds and sells flour, making it both a visual spectacle and a fully operational stone-ground mill. Grade I listed.
3. Cranbrook Union Mill, Kent (1814)
The Union Mill at Cranbrook in the Kentish Weald is the tallest smock mill in England, standing nine metres to the curb (the point where the rotating cap sits on the fixed body). It was built in 1814 and has six floors of working machinery. The mill is managed by the Cranbrook Union Mill Trust and the Kent County Council. It grinds on National Mills Weekend and other designated events. Grade I listed. Smock mills are particularly associated with Kent and Sussex; the Union Mill is the finest surviving example.
4. Saxtead Green Post Mill, Suffolk (18th century)
Saxtead Green Post Mill is maintained by English Heritage as a working monument. The mill's present form dates largely to the eighteenth century, though there has been a mill on the site since at least 1309. It is a classic Suffolk post mill — large buck, round-house below, four common sails — and it turns on demonstration days during the summer season. English Heritage trains volunteer millers at Saxtead. Grade I listed. The round-house (the brick-built base of the post trestle) is used as a storage area and is visitable on open days.
5. Brixton Windmill, London (1816)
Brixton Windmill in south London is the oldest surviving windmill in Greater London and the only one in the area still capable of operating. It is a tower mill built in 1816 to grind grain for the then-rural Brixton area. By the 1860s, London's urban expansion had surrounded it and it ceased commercial operation. It was restored to working order between 2011 and 2019 by the Friends of Windmill Gardens and grinds flour on designated open days. Grade II* listed. The mill's urban setting — between Victorian terraces in a now-diverse south London neighbourhood — makes it one of the more unusual mill visits in the country.
6. Sibsey Trader Mill, Lincolnshire (1877)
The Trader Mill at Sibsey in Lincolnshire is a six-sail tower mill built in 1877, one of only three six-sail windmills remaining in England. It is managed by English Heritage and grinds grain on demonstration days. The Lincolnshire landscape supported more multi-sail mills than any other English county; the Trader Mill is the finest survivor of this regional tradition. Grade I listed.
7. Heage Windmill, Derbyshire (1797)
Heage Windmill near Belper in Derbyshire is the only working stone tower mill in England north of the Trent. Built in 1797, it is a six-sail tower mill of local gritstone construction and the sole survivor of several stone mills that once stood in the Amber Valley. Managed by the Heage Windmill Society, it grinds regularly and is open most summer weekends. Grade II* listed. The stone construction distinguishes it from the brick tower mills of Lincolnshire and East Anglia.
8. Wymondham Windmill, Leicestershire (1814)
The tower mill at Wymondham in Leicestershire is a four-sail tower mill in working order, managed by a local preservation trust. It is one of the better- preserved examples of the East Midlands tower mill tradition and grinds on National Mills Weekend. Grade II* listed. Leicestershire has few surviving mills — the county's agricultural economy was more oriented toward animal husbandry than grain production — which makes the Wymondham mill an isolated but significant survivor.
9. Holton le Moor Mill, Lincolnshire (1868)
The tower mill at Holton le Moor in Lincolnshire is a four-sail tower mill dating to 1868, in working order and maintained by the local parish and a preservation group. It grinds on open days. Lincolnshire has more surviving windmills than any other English county, reflecting the county's historically dominant role in English grain production. The Holton le Moor mill is representative of the mid-Victorian Lincolnshire tower mill at its most typical. Grade II listed.
10. Hessle Weedley Mill (Whiting Mill), East Yorkshire (c.1820)
The Hessle Weedley mill, a tower mill near the Humber estuary, represents the Yorkshire milling tradition. Tower mills in Yorkshire were often associated with the chalk wold farms east of York; the Hessle example is in the Humberside transition zone. It is listed as a heritage structure and has been partially restored. Yorkshire has fewer working mills than Lincolnshire or Suffolk, and the Hessle mill is one of the more intact survivors from the county's limited wind-milling heritage.
Planning a UK mill visit
National Mills Weekend (second weekend of May) is the single best opportunity to visit working mills across the country, with around 200 sites participating. The map shows all tagged UK mills, from the Lincolnshire tower mills to the Kent smock mills to Brixton's urban survivor. Filter by working status to identify mills that operate on a regular schedule rather than just on heritage events.
