Thecustodian helmet is a type of helmet worn predominantly by male police officers in theUnited Kingdom and within certain other places around the world.[1] First used by theMetropolitan Police in London in 1863, the BBC labelled the custodian helmet a "symbol of British law enforcement".[2] They are worn by maleconstables and sergeants on foot patrol.[3] A cultural icon, it has featured in films, TV series and other media involving British police.[2]
The custodian helmet is the headgear traditionally worn by malepolice constables andsergeants while on foot patrol in England and Wales.[3] Officers of all ranks in most forces are also issued a flat,peaked cap that is worn on mobile patrol in a vehicle. Ranks above sergeant wear the peaked cap only. However, some inspectors wear the custodian helmet, but with two silver bands around the base (to match the two pips worn as rank insignia) to denote their position.[4]
Claimed by some sources to have been based on the spikedpickelhaube[dubious –discuss] worn by thePrussian Army,[5][6] it was first adopted by the LondonMetropolitan Police in 1863 to replace the "stovepipe"top hat worn since 1829.[2] In 1863, the Metropolitan Police replaced the previous uniform of white trousers, swallow-tailed coat and top hat in favour of very dark blue trousers, a more modern button-up tunic and the early type of helmet which had an upturned brim at the front and a raised spine at the back, running from the bottom to the top of the helmet, which became known as the "coxcomb".[7]
The early Metropolitan Police helmet had a "garter" style badge on the front of the helmet which had the officer's personal number anddivisional letter in the centre, backed by a leather insert. This was surrounded by a wreath design which had the words "Metropolitan Police" around the outside and was topped with the reigning monarch's crown. This style changed in 1875, when an early version of theBrunswick star was adopted without the upturned brim seen in the previous style. There was much variety in the style of helmets during this period. The form of the helmets gradually converged with the "foreign service" and "home service" helmets adopted by the British Army in the late-1870s.
During the 1930s, theHome Office attempted to standardise the design of the helmets with the "Home Office Pattern", after it became evident that since the Metropolitan Police had adopted it and produced their own badge, many small county and borough police forces followed suit and individually adopted their own style badges and designs, which led to many different styles and designs. Some forces adopted the helmet without any badge; others designed their own, usually with the county's arms or crest in the centre. A few forces adopted an Australian style bush hat and one wore a helmet constructed of straw.[8][9][10]

The "Home Office Pattern" consisted of a helmet with theBrunswick star badge (commonly known as a "helmet plate") which would feature the reigning monarch's cipher, with the name of the force imprinted on the plate. The top of the helmet had a "rose top", which was a raised metal rose, largely used as an ornament to cover the ventilation hole. However, this standardisation process was largely unsuccessful, with many different designs being worn by today's police forces nationally.
Until the 1970s and, in certain areas, the 1980s, the helmet internally had only a sweat band to allow it to sit correctly on the wearer's head, with a single chin strap. The helmet plate and either a "coxcomb" or "rose top" fixed to the top of the helmet, were fitted by pressing the metal lugs attached to the badges through the helmet and then having small matchstick-size pieces of wood pushed through the lugs to secure them. Other helmet furniture included a "ball top" and in some cases a "spike top".

During the 1970s and 1980s, before specially adaptedriot helmets were introduced, officers were expected to conduct public order and crowd control in the standard beat duty helmet. The cork construction provided little protection against attack and thrown missiles. In order to provide more protection, the construction of the helmets changed. Visually they remained the same, but instead of being constructed of cork they were now made out of a very hard-wearing plastic material and covered in felt. Internally, they were padded with foam fitted into the shell of the helmet with a webbing-style harness to allow it to sit on the head in the correct manner. Two chin straps were added at this time, a thin leather strap for normal duties, and a "public order strap" which was made of thick material and included a chin-cup to securely hold the helmet on the head. As well as these changes, helmet plates were altered so that the fixings on them were no longer lugs, but were prong-type pins which were inserted into the helmet and spread apart, so that if the helmet plate was hit by a missile, the lugs would not cause injury to the wearer. Although NATO riot helmets replaced the Custodians for public order, Custodian helmets are still currently used to control football crowds, and protests. As late as 2024, police used Custodian helmets for public order as riot gear was not available. During theLondon Riots in 2011, theBritish Transport Police andMetropolitan Police were equipped only with Custodian helmets, shields and batons.[11] During the2024 riots, a number of forces utilised Custodian Helmets as opposed to NATO helmets. One such force wasSussex Police where officers were deployed only with Custodian Helmets and utilised riot chin straps during unrest inBrighton.
All police forces in England and Wales have their own "helmet plates" attached to the front of the helmet, most of which feature the county's coat of arms/crest or theroyal cypher in the centre. Also, most helmet plates now feature parts with colouredenamel, such as the force name or crest. The additional of enamel to helmet plates started around 1985; most forces before this had plain metal ones with no or little colour. Some forces also used "night plates" for unobtrusive use at night-time, usually darkened apart from the centre, instead of metal "day plates". This practice had almost completely ceased by 1973.
Police forces in the UK did not issue custodian helmets toSpecial Constables up until around 1995; however, those forces retaining the helmet now issue them to all male officers.
The traditional cork construction often ledCID personnel to call their uniformed colleagues "woodentops" (the name ofa children's TV programme).
Police Community Support Officers only wear peaked caps, which have a blue or grey band on them rather than the police officer'sSillitoe tartan to distinguish them from police officers.
The standard equivalent for female officers is a "bowler" hat. This is shorter, chequered around the rim, and structurally reinforced to equal the custodian's protection. Uniquely,Staffordshire Police issues custodian helmets to all female constables forlevel 2 public order duties (and level 3 when requested).[12][13] Other forces may allow individual female officers to wear custodians if preferred, but will otherwise issue them with bowlers or flat caps by default.[14]

Of the 43Home Office territorial forces inEngland and Wales, 20 currently use the comb style, 18 use the rosetop style, and four use the ball style. Some forces worespikes on top of the helmet, although these have now been completely phased out.
Since the early 1950s, helmets have no longer been worn by police officers inScotland, but may be seen worn by Metropolitan Police officers when on Royal duties in Scotland. They ceased to be worn inNorthern Ireland after the 1920s, except for night patrol work inBelfast andDerry until the early 1960s.
During 2002, attempts were made by police forces in England to replace the custodian helmet. Some forces adoptedbaseball caps for a very short time, but almost all reverted to the helmet or peaked cap.Humberside Police have adopted a "squat" helmet which is considerably shorter than the normal size helmets. This is currently in use.[15]
The custodian helmet is an iconic symbol of British policing, still used by a number of metropolitan police forces, and I am delighted that they will be returning to the streets of Thames Valley.
Thames Valley Police discarded the helmet in 2009 due to budget constraints but brought them back for use in 2018 following a successful trial in Reading, whereasWest Yorkshire Police announced that helmets would cease to be worn after 2015 because staff found them unsuitable for normal duties.[17] West Yorkshire Police did, however, retain the helmets for use on ceremonial occasions.Lancashire,Cheshire andGloucestershire Constabularies announced in February 2017 that as part of uniform changes their custodian, bowler and peaked caps were to be replaced by unisex reinforced baseball caps, known as "Bump Caps". A small number of the traditional headdresses were retained for ceremonial occasions.[18]

In 2006/7Gwent Police andNorth Wales Police replaced all headgear in favour of baseball caps. In 2010/12 the two forces announced that peaked caps and helmets would return as baseball caps were seen as unprofessional and difficult for the public to see and recognise as police headgear. This change to revert to wearing helmets led to all forces in Wales to continue wearing the custodian helmet.
Greater Manchester Police attempted to phase out custodian helmets around 2011/12 in favour of peaked caps. A few months later the custodian helmet was brought back and peaked caps were no longer issued to officers below the rank of Inspector. This meant that the custodian was the only headgear worn by constables and sergeants at that time. However, since 2017 peaked caps and custodian helmets have both been issued for use on patrol.
Northamptonshire Police andLeicestershire Police both replaced custodian helmets with gender-neutral caps in 2017, but later reinstated them in 2019 and 2022 respectively.[19]
Cheshire Constabulary reinstated Custodian Helmets in 2024 in an effort to increase High Visibility policing. The move received “overwhelmingly positive” comments from the public. Supt. Adam Ross, Force Commander at Warrington said: ”As well as being practical and distinctive they also form part of Our rich history and what the public expects the Police to look like”.[citation needed]
Of the 43 territorial police forces in England and Wales, 40 are currently using the custodian helmet.

Both chin straps can be folded up inside the helmet when not in use for more strenuous activity. Most officers choose not to use the chin strap for day-to-day duties.
All forces except theCity of London Police,Hampshire Constabulary andWest Mercia Police use theBrunswick star as the basis for their helmet plate. The helmet worn by members of theIsle of Man Constabulary is white,[20] rather than blue, and officers of theStates of Jersey Police on duty inSt Helier wear white helmets during the summer months.[21]
In modern production, hat makers take approximately 30 minutes to complete a single custodian helmet,[22] all of which are made by only four companies: Hobson and Sons (London) Ltd; Christys, ofStockport; Compton Webb (C.W. Headdress Limited), of Oxfordshire; and Helmets Limited, ofWheathampstead.[1]
The initial process begins with the making of the helmet shell using avacuum forming machine and a metalmould. A sheet of black fortified plastic is heated and then lowered over the mould, where a vacuum pulls the plastic into shape over the mould. Once hardened instantly, a rubber mallet is used to release the plastic from the mould so that the excess plastic around the brim of the helmet can be trimmed with abandsaw and sanded. The helmet's fabric covers are made out ofwater-repellentwool that are cut in halves andstitched together to give the helmet a distinctive centred, front-to-backseam. Moving down the line of production, glue is applied to both the inside of the fabric cover and the outside surface of the helmet shell, the fabric cover is then steamed and stretched tightly over the shell to preventbuckling. A wooden tool is carefully used to smooth away any air bubbles as well as to ensure the fabric cover is in full contact with the helmet shell; excess fabric is cut away.
Now halfway through production, the helmet is left to dry for several minutes. Once it is dry, black plasticpiping is sewn around the brim of the helmet to reinforce it and give it a neater edge. For rosetop and ball helmet styles, the metal fastening prongs or screws of thechrome fixtures are dipped in chalk to mark their positions on thecrown of the helmet; holes are then drilled and the fixture is secured. For comb-style helmets, the crest, which has vent holes incorporated into the design, is also fixed by prongs or simply glued into place at the top end of the comb. For all helmet styles, two vent holes arepunched on both sides of the helmet and fitted with black metalgrommets, making a total of four vent holes.
The adjustable head harness is made out of strips of fabric tape and foam stitched onto a plasticheadband; this is then inverted so that a modern-patternchin-strap assembly and traditional leather chin-strip can be stitched on as well. The harness assembly is lowered into the helmet and secured with an industrialstapler. Depending on the helmet style, a broad plastic band,[23] narrow black metal band,[24] narrow chrome metal band,[25] or broad chrome metal band[1][26] is wrapped around the helmet and pinned down, concealing thestaples. For additional protection, a sponge liner is tucked into the helmet.
Near the end of production, a hole is drilled on the front end of the helmet and an appropriate police helmet plate is screwed on. The helmet then issized, cleaned, and inspected. Finally, the helmet islabelled and given a good brush to bring up thepile. It is then ready to be shipped on to an awaiting police force.
A cultural icon, the custodian helmet has featured in films, TV series and other media involving British police.[2] Often playing minor characters, in the UK they have appeared in kids shows such asThomas the Tank Engine & Friends andFireman Sam, television comedy shows such asThe Benny Hill Show,The Young Ones andMonty Python's Flying Circus (the latter including "The Funniest Joke in the World" sketch), and critically acclaimed films includingThe Ladykillers (1955),Hot Fuzz (2007) andPaddington (2014).[27][28][29][30] Appearing as minor characters in international media (such asMary Poppins (1964) andSherlock Holmes (2009)), constables on foot patrol wearing their custodian helmet have also appeared in the background of shots to indicate a traditional British setting (much like other features unique to a British street such as thered telephone box, thered double-decker bus or ablack taxi which have been used as anestablishing shot for London).[31][32][33][34] Dressed as a constable when introducingQueen on stage atLive Aid in 1985, comedianMel Smith undoes the chin strap before removing his helmet and shouting into the mic, "her majesty, Queen!"[35]

Helmets closely following the British model were widely worn by the police forces ofCanada,Australia andNew Zealand from the late nineteenth century on. These were eventually discarded as being inconvenient to wear when in vehicles or providing insufficient protection from the sun when on foot patrol. The "bobby helmet" was replaced by apith helmet for police inVictoria, Australia from 1947, as well by a cap.[36]
TheNew Zealand Police retained a white version of the custodian helmet until 1995, when it was replaced by Forage caps and more recently baseball caps.[37] The white helmet was also used by theSamoa Police, who still make limited use of it. TheToronto Police Service discontinued regular use of the helmet in 1945 in favour of aforage cap[38] but retains the white helmet for use by the Toronto Police Chief's Ceremonial Unit. TheRoyal Newfoundland Constabulary currently uses the helmet for some officers (usually senior) and for special events.
As well as in the UK, other forces currently using the custodian helmet include theStates of Jersey Police,States of Guernsey Police Service,Isle of Man Constabulary,Royal Gibraltar Police, andBermuda Police. The term "custodian" originated as a specific make of helmet used in Britain in the late-twentieth century. Because of this, "custodian" was never an official or unofficial name for similar helmets worn in other parts of the Commonwealth.

CertainItalian municipal police forces use a white custodian-style helmet, particularly in open air duties, such as when directing traffic.
TheMonaco Prince'sCarabiniers Company use a white helmet in summer and a blue one in winter.
The PortuguesePublic Security Police (PSP) constables wore a custodian-style helmet from 1936 to 1958. The helmets were made of cork, covered with dark blue fabric, having on the front a silver PSP star (six points star with thePortuguese Shield in the centre). The police constables serving astraffic guards (Portuguese:polícias sinaleiros) wore a similar helmet in cork covered with white fabric for use in the summer and in aluminum painted white for use in the winter. While the general police constables' blue helmets ceased to be used, the white traffic guards' helmets continued to be used and become traditional. These helmets are still worn by the rare traffic guards that remain in the PSP of today.[39]
Jordanian police officers in some assignments wear a custodian cover topped with a spike and incorporating a cloth shade for the back of the neck.
Until the mid-20th century, British-style helmets were in use with the municipal police forces of several Dutch cities, most notablyThe Hague.[40][41]
Some early uniforms in the United States police forces had variants of a helmet. ThePennsylvania State Police incorporated a cloth covered helmet, manufactured in England. TheNew York Police Department used a helmet, grey for summer and blue for winter from 1872 to 1912, as didseveral other American police forces. The helmet features in theKeystone Cops films. Several photographs exist that show a funeral procession for officer John L. Briscoe inStockton, California. Briscoe was killed in the line of duty on 5 February 1917.[42] Some of the line officers in the procession wore a modified custodian helmet with a leather band just above the rim and a silver badge on the front.
The Custodian Helmet is worn by policemen in England and Wales as the traditional headgear of the 'Bobby on the beat', worn by constables and sergeants on foot patrol.
