Police ranks are a system of hierarchical relationships in police organisations. The rank system defines authority and responsibility in a police organisation, and affects the culture within the police force. Usually, uniforms denote the bearer's rank by particular insignia affixed to the uniforms.

Most of the police forces of the United Kingdom (including those of the British Overseas Territories and the Crown Dependencies) use a standardised set of ranks. However, as law enforcement in the United Kingdom is organised separately in the three jurisdictions of England and Wales, Northern Ireland, and Scotland, and as most law enforcement is carried out by police officers serving in regional police services known as territorial police forces, some variations in rank organisation, insignia and responsibilities may occur within the United Kingdom. An example of this are the slight variations in the most senior ranks of the Metropolitan Police and City of London Police. Parallel to the regional services are UK-wide agencies, such as the British Transport Police and the national specialist units of certain territorial police forces, with a possibility of further variations.

Due to policing in many countries developing from military organisations and operations, police ranks in many countries follow a logic similar to that of military ranks. Most of the British police ranks that exist today were, however, deliberately chosen by Home Secretary Sir Robert Peel so that they did not correspond with military ranking. They were enacted under the Metropolitan Police Act 1829.

History of police ranks

All police forces have used a wide variety of ranks to meet their organisational needs, especially the Metropolitan Police Service. Ranks have been created, abolished, amalgamated and sometimes revived during the history of British policing.

In the following table, "MET only" means those ranks are specific for the Metropolitan Police.

Powers

In law, every attested police officer is a constable whatever their actual rank, in the sense that officers of any rank have the same powers of arrest. The basic police powers of arrest and search of an ordinary constable are identical to those of a superintendent or chief constable; however certain higher ranks are given administrative powers to authorise certain police actions. In England and Wales, these include the powers to:

• authorise the continued detention of up to 24 hours of a person arrested for an offence and brought to a police station (granted to sergeants and above at designated police stations),
• authorise section 18 (1) PACE house searches (granted to inspectors and above), or
• extend the length of prisoner detention to 36 hours (granted to superintendents),
• extend the length of bail from a police station to three months (granted to superintendents)

In relation to police officers of the Home Office or territorial police forces of England and Wales, section 30 of the Police Act 1996 states that "a member of a police force shall have all the powers and privileges of a Constable throughout England and Wales and the adjacent United Kingdom waters". Police officers do not need to be on duty to exercise their powers and can act off-duty if circumstances require it (technically placing themselves back on duty). Officers from the police forces of Scotland and Northern Ireland and non-territorial special police forces have different jurisdictions. See List of law enforcement agencies in the United Kingdom, Crown Dependencies and British Overseas Territories for a fuller description of jurisdictions.

Detective, reserve, training and temporary ranks

Detectives

Officers holding ranks up to and including chief superintendent who are members of the Criminal Investigation Department (CID) or Special Branch (and certain other units) have the prefix "detective" before their rank. Due to the nature of their duties, these officers generally wear plain clothes (except for ceremonial purposes) and so do not wear the corresponding rank insignia; however, they still operate within the same structure as their uniformed counterparts.

In the United Kingdom, detective ranks are not superior to those of uniformed officers and a detective has the same powers and authority as a uniformed officer of the same rank. The "detective" prefix designates that the officer has received suitable training and passed related examinations to conduct criminal investigations.

Special constables

There are various grades of special constable which assist in the tasking and management of the constabulary. The ranks are management grades; those holding them are not "sergeants" or "inspectors" for the purposes of the law (for example, authorisations to order the removal of disguises or to set up roadblocks). Originally, specials held the same ranks and used the same rank insignia as regular officers, but there was a general shift to distinct terms such as "area officer" and "divisional officer" in the 1980s. However, since 2000, the National Policing Improvement Agency has encouraged special constabularies to return to rank structures and epaulette insignia identical to their regular counterparts. Although most forces have now reverted to regular rank titles (with the prefix "special"), only some have reverted to regular rank insignia. Senior special constables have no authority over regular officers, but very experienced officers may occasionally be given administrative supervision of mixed units of regular and special constables for certain events where no regular supervisory officer is available.

Trainee, temporary and acting ranks

Constables who are training to become detective constables sometimes bear the title trainee investigator (T/I) or trainee detective constable (T/DC).

The prefix "temporary" before a rank (e.g. temporary detective sergeant, abbreviated T/DS) denotes an officer who has been temporarily promoted to a rank (and so who does actually hold that rank, albeit on a temporary basis), whilst the prefix "acting" (e.g. acting inspector, abbreviated A/Insp) denotes an officer who is performing the role of a higher rank than the one actually held (sometimes informally termed "acting up"). Temporary ranks are often used for set periods (e.g. a six-month appointment to a particular role), whereas acting ranks, although sometimes held for extended periods, are often used for a very short time (e.g. a single shift when additional supervisory officers are required, or to replace an officer on short-term leave).

Under section 107 of the Police and Criminal Evidence Act 1984 (England and Wales only), sergeants and chief inspectors may be designated (by an officer of at least the rank of superintendent) to exercise the powers of an inspector or a superintendent respectively. Such a designation will generally accompany such an officer being given an acting rank, so for most operational purposes there is no difference between substantive, temporary and acting ranks at Inspector and above (although there may be differences as to pay, pensions and insignia). However, under section 36 of that act, only substantive sergeants may be appointed custody officers.

Ranks of unwarranted related services

Police cadets

Ranks within volunteer police cadet schemes vary considerably across the territorial police forces.

Police community support officers (PCSO)

Police community support officers, in general, do not have a rank system. The South Yorkshire Police and Kent Police, however, have designated PCSO supervisors.

Traffic wardens

Traffic wardens were administered by the police and exercised some police powers to control traffic or issue fixed penalty notices for traffic offences. Very few police Traffic Wardens now exist with a legacy of only 10 police traffic wardens remaining in England & Wales. Section 46 of the Policing and Crime Act 2017 has in effect abolished police traffic wardens allowing police to focus on their core duties. The duties of traffic wardens have been passed to local authority civil enforcement officers (formerly parking attendants) who, under decriminalised parking enforcement, have powers to issue penalty charge notices for breaches of parking laws on highways or in local authority car parks and compel the production of a disabled parking permit (blue badge) for inspection.

A similar situation has developed in Scotland with the functions of traffic wardens being taken over by local councils. In many areas parking legislation has been decriminalised and is enforced solely by council-employed parking attendants.

Rank as related to officer identification numbers

All officers have a unique identification number. These are usually referred to as shoulder or collar numbers, referring to the fact that they were once worn on the uniform collar and later on the epaulettes by constables and sergeants. Uniformed officers in many forces still wear them on the epaulettes, but other forces have badges or other ways of displaying their identification numbers. Kent Police, for instance, refers to its numbers as force numbers and officers wear them on a velcro tab on their stab vest or on a badge attached to their shirt or tunic. Officers in all forces of the rank of inspector or above do not usually wear their numbers.

In most forces these identification numbers are simple numbers, with one to five digits.

The Metropolitan Police and Police Scotland, as well as a few other forces, use a letter and number system:

Metropolitan Police:

• Sergeant: Borough code and one, two or three digits
• Constable: Borough code and three or four digits
• Special constable: Borough code and four digits, usually beginning with the number 5 (8 for traffic/transport or 9 for specialist units)
• PCSO: Borough code and four digits, the first digit being a 7

Police Scotland:

• Sergeant and constable: Division letter and three or four digits
• Special constable: Division letter and four digits, the first digit being a 7

In the Metropolitan Police, the borough code is a two-letter code which follows the digits (but displayed above them on epaulettes). Before the reorganisation into boroughs, each division had a different code, with sergeants having two-digit numbers and constables having three-digit numbers.

Rank insignia

Badges of rank are usually worn on the epaulettes. However, when in their formal uniform sergeants wear their rank insignia on their upper sleeves. When police tunics had closed collars (not open collars as worn with ties), constables and sergeants did not wear epaulettes but had their divisional call number on their collar (hence they are still often referred to as collar numbers). Sergeants wore their stripes on their upper sleeve. Inspectors and more senior ranks wore epaulettes at a much earlier stage, although they once wore their rank insignia on their collars. Most forces no longer use divisional call numbers, and retain only the collar number and rank insignia.

Great Britain

Senior officers usually wear distinguishing marks around the outer edge of the peaks of their caps (or under the capbadge for female officers, who do not wear peaked caps). Normally this is a raised black band for inspectors and chief inspectors, a silver (gold in the City of London Police) band for superintendents and chief superintendents, and a row of silver oak leaves for chief officers. Chief constables, the Commissioner of the City of London Police, and all commissioner ranks of the Metropolitan Police wear oakleaves on both the outer and inner edges of their peaks (or a double row beneath the capbadge for female officers). In Scotland, however, the mark is a silver band for inspectors and chief inspectors, a silver band and silver oakleaves on the outer and inner edges of the peak respectively for superintendents and chief superintendents, and silver oakleaves on the outer and inner edges of the peak for all chief officers.

Additionally, officers at or above the rank of commander or assistant chief constable wear gorget patches on the collars of their tunics. The gorget patches are patterned after those worn by general officers of the British Army and Royal Marines; the police versions, however, are of silver on black (gold on black in the City of London Police) rather than gold on red, in keeping with the police uniform colours.

The ranks below are used by all territorial forces in the United Kingdom, and the specialist national forces: the British Transport Police, Ministry of Defence Police, and Civil Nuclear Constabulary. Other specialist forces, and those outside of the United Kingdom (including British Overseas Territories such as Bermuda and Gibraltar, which are parts of the British sovereign territory in most of which internal competencies of governance are mostly delegated to local governments, and the Crown Dependencies of the Channel Islands and the Isle of Man, which are not parts of the British sovereign territory) use the same general system, but often have fewer senior ranks.

Chief constable is the title of the head of each United Kingdom territorial police force except the Metropolitan Police and City of London Police, which are headed by commissioners. Ranks above chief superintendent are usually non-operational management roles, and are often referred to as "chief officer" ranks, but the longer phrase "chief police officer" or similar in legislation is specifically a commissioner or chief constable, a "senior police officer" being their immediate deputy. The Commissioner of the Metropolitan Police is often considered to be the highest police rank within the United Kingdom, although in reality every chief constable and the two commissioners are supreme over their own forces and are not answerable to any other officer.

Epaulettes are normally black with white sewn on or silver metal insignia, although high-visibility uniforms are often yellow with black insignia.

Notes	Hats worn by inspectors and chief inspectors have raised black bands along the outer edge of the peaks for male officers or black arcs below the cap badges for female officers. All English and Welsh forces retain the custodian helmet and other traditional headwear for ceremonial duties.

British Transport Police

As a variation to the standard set, the deputy chief constable of the British Transport Police wears two rows of oak leaves on their hat.

Northern Ireland

The Police Service of Northern Ireland (PSNI) adopted the same rank system as elsewhere in the United Kingdom on 1 June 1970, but has a different version of the rank insignia, with the star from the PSNI badge replacing the crown. Unusually, the star is worn below the pip by chief superintendents and by the chief constable, who wears both symbols above his tipstaves. The PSNI has retained the RUC's distinctive inverted (point-up) sergeants' chevrons, worn on the lower sleeve in formal uniform. PSNI officers do not wear the custodian helmet and female officers wear a different hat from other forces.

The PSNI rank structure and epaulette insignia is the same as the territorial police in Great Britain, except that the crown is replaced with the design from the PSNI badge and sergeants' chevrons are point up. In addition to the epaulettes being a green colour rather than a black, this is to match their green uniforms.

Police Service of Northern Ireland ranks
Rank	Chief constable	Deputy chief constable	Assistant chief constable	Chief superintendent	Superintendent	Chief inspector	Inspector	Sergeant	Constable
Epaulette insignia

Headgear rank marking is the same as for England and Wales.

Scotland

Police Scotland headwear is slightly different for the following ranks:

• Inspectors and chief inspectors wear a hat with a silver band instead of a black one.
• Superintendents and chief superintendents wear a row of oak leaves within the silver band.
• Assistant chief constables and deputy chief constables wear two rows of oak leaves.

Territorial police forces variations

City of London Police

City of London Police ranks
Rank	Commissioner	Assistant commissioner	Commander	Chief superintendent	Superintendent	Chief inspector	Inspector	Sergeant	Constable
Insignia
Note	City of London Police insignia are worn on square patches on the upper arm of working dress or on the epaulettes in more formal dress.

City of London Police insignia is gold where that of other forces is silver. For example, rank insignia and collar numbers on epaulettes are gold, as are the bands and oak leaves on the caps of senior officers, and officers of or above the rank of commander wear gold-on-black gorget patches on the collars of their tunics.

The City of London Police also previously had variations for some acting ranks such as sergeant and inspector: acting sergeants wore their chevrons above their divisional letters (or later "CP" for all officers, following the abolition of the force's divisions), whereas substantive sergeants wear them below their collar numbers. Acting inspectors were denoted by a crown in the place of their divisional letters, whilst keeping their collar number and chevrons.

The City of London Police use a different colour scheme for their police headwear. Instead of the black and white sillitoe "tartan" they use red and white. The assistant commissioner and commander wear a single row of oak leaves on their hats, and only the commissioner wears two rows.

Merseyside Police

Inspectors and chief inspectors in Merseyside Police wear silver instead of black lace on their hats, as did Liverpool City Police before them.

Metropolitan Police

Metropolitan Police ranks
Rank	Commissioner	Deputy commissioner	Assistant commissioner	Deputy assistant commissioner	Commander	Chief superintendent	Superintendent	Chief inspector	Inspector	Sergeant	Constable
Epaulette insignia

The Metropolitan Police uses different ranks above chief superintendent. The fabric used in the crowns is blue, whereas other police forces use red. Although they rank as deputy chief constables, deputy assistant commissioners wear two rows of oak leaves on their hats.

Isle of Man Constabulary

Epaulette insignia

The Isle of Man police ranks follow the structure of other British police rank structures however it is notably missing the chief superintendent and assistant chief constable ranks within their own structure. The epaulettes for the constables and sergeants also have an addition of the Isle of Man Constabulary logo and motto above their collar numbers. Headgear rank marking is the same as for England and Wales.

Isle of Man Police ranks
Rank	Chief constable	Deputy chief constable	Superintendent	Chief inspector	Inspector	Sergeant	Constable
Epaulette insignia

Special constabularies insignia

Special constabulary epaulettes frequently bear the letters SC (with or without a crown above) to differentiate them from regular officers. Within the City of London Special Constabulary is the Honourable Artillery Company Specials; members of this unit wear HAC on the shoulders in addition to other insignia. Senior special constables wear the same markings on their hats as equivalent regular ranks.

Notes	Blank spaces in the table indicate that a rank is not used in a force's structure. This table of constabularies is not complete.

There is a large variation in the design of epaulettes used across Great Britain for specials. This has been recognised at national level and as part of the Special Constabulary National Strategy 2018–2023 the structure and insignia is under review with the intention to standardise. Other special constabularies use combinations of bars, half bars, pips, crowns, laurel wreaths, collar numbers, force crests and the SC identity (with or without a crown) to distinguish ranks (and/or role).

Miscellaneous police forces

There are, in the United Kingdom, a number of miscellaneous constabularies. These are not operated, regulated or funded by the Home Office, although they are fully authorised (by Act of Parliament) establishments. In general, they provide the policing for ports, docks, tunnels, or other particular institutions. Although these forces tend to require high standards of training and accountability, which closely mirror those of the Home Office police forces, they are usually much smaller in terms of personnel, and therefore utilise fewer of the 'standard' ranks.

Public order roles and rank insignia

Officers taking part in public order and public safety (POPS) events and incidents wear colour-coded rank slides to denote command and support roles. Bronze commanders can be of varying ranks and not just chief inspectors as shown below. Tactical advisers can also be of differing ranks, but are most commonly constables or sergeants. It is a requirement under the College of Policing Public Order Manual that all officers, regardless of rank, display an identifying number on their epaulettes. Therefore, ranks such as inspector have collar/warrant numbers displayed on their public order colour-coded epaulettes that they might not have as part of their normal uniform.

Police community support officers (PCSO)

Police community support officers bear epaulettes with the words "Police community support officer" and their shoulder number, or, in the Metropolitan Police, a borough identification code and shoulder number. South Yorkshire Police PCSO supervisors wear a bar above the words "Police community support officer supervisor" and the shoulder number.
