List of law enforcement agencies in the United Kingdom, Crown dependencies and British Overseas Territories
There are a number of agencies that participate in law enforcement in the United Kingdom which can be grouped into three general types:
- Territorial police forces, who carry out the majority of policing. These are police forces that cover a police area (a particular region) and have an independent police authority. Current police forces have their grounding in the Police Act 1996 (in England and Wales), a combination of Police (Scotland) Act 1967 and Police and Fire Reform (Scotland) Act 2012 (in Scotland) and the Police (Northern Ireland) Act 2000 (in Northern Ireland), which prescribe a number of issues such as appointment of a chief constable, jurisdiction and responsibilities.
- National law enforcement bodies, including the National Crime Agency and national police forces that have a specific, non-regional jurisdiction, such as the British Transport Police. The Serious Organised Crime and Police Act 2005 refers to these as 'special police forces', not including the NCA which is not a police force. In addition, there are non-police law enforcement agencies, whose officers are not police officers, but still enforce laws, and other bodies with solely investigatory powers.
- Miscellaneous police forces, mostly having their foundations in older legislation or common law. These are responsible for policing specific local areas or activities, such as ports and parks. Before the passing of recent legislation such as the Serious Organised Crime and Police Act 2005, they were often referred to as 'special police forces'; care must therefore be taken in interpreting historical use of that phrase. These constabularies are not within the scope of the legislation applicable to the previously-mentioned organisations but can still be the subject of statutes applicable to, for example, docks, harbours or railways. Until the passing of Railways and Transport Safety Act 2003, the British Transport Police was such a force.
The majority of law enforcement in the United Kingdom is carried out by territorial police forces that police the general public and their activities. The other types of agencies are concerned with policing of more specific matters.
Over the centuries there has been a wide variation in the number of police forces in the United Kingdom, with a large number now no longer in existence.

Territorial police forces
England and Wales
Except in Greater London, each territorial police force covers one or more of the local government areas (counties) established in the 1974 local government reorganisations (although with subsequent modifications), in an area known in statute as a police area. These forces provide the majority of policing services to the public of England and Wales. These forces have been known historically as "Home Office police forces" due to the central government department, the Home Office, being responsible for and providing the majority of funding these police forces. Despite the implication of the term, all police forces are independent, with operational control resting solely with the chief officer of each force (the Chief Constable or with regard to the Metropolitan Police and City of London Police forces, their respective Commissioners); each force was overseen by a Police authority until these were replaced by Police and Crime Commissioners in 2012.
The Police Act 1996 is the most recent piece of legislation, which outlines the areas of responsibility for the 43 territorial forces of England and Wales (found in Schedule 1 of the Act).
Constable is the lowest rank in the police service, but all officers, whatever their rank are "constables" in terms of legal powers and jurisdiction. Police officers in territorial police forces in England and Wales derive their jurisdiction from Section 30 of the Police Act 1996. This section outlines that such officers have jurisdiction throughout England and Wales and also the adjacent United Kingdom waters. Special Constables, who are part-time, volunteer officers of these forces, used to have a more limited jurisdiction – limited solely to their own force areas and adjacent forces. Since 1 April 2007, however Special Constables of England & Wales have full police powers throughout those two countries. This means that, in contrast to the majority of countries, all UK volunteer police officers now have exactly the same powers as their full-time colleagues. There are a number of situations in which the jurisdiction of a constable extends to one of the other countries, and constables of one jurisdiction do have reciprocal powers of arrest in each others jurisdictions as a matter of course – see the main article for details.
As of March 2010 police numbers in England and Wales were:

Most police powers and functions have been inherited by the Scottish Government and Scottish Parliament from the Scottish Office. Areas for which legislative responsibility remains with the UK Government include national security, terrorism, firearms and drugs. The Police (Scotland) Act 1967, as amended, was the basis for the organisation and jurisdiction of the eight former territorial forces in Scotland that were formed in 1975. These forces covered one or more of the areas of the local government regions established in the 1975 local government reorganisation (and since abolished), with minor adjustments to align with the post-1996 council area borders. These forces provided the majority of police services to the public of Scotland, although Scottish police officers also have limited jurisdiction throughout the rest of the United Kingdom as required (See above comments under English and Welsh forces).
In 2011, the Scottish Government announced that it planned to amalgamate the eight territorial forces in Scotland, along with the Scottish Crime and Drug Enforcement Agency, into a single agency. The Police and Fire Reform (Scotland) Act 2012, an Act of the Scottish Parliament, codified this amalgamation and brought about the new Police Service of Scotland (to be known as "Police Scotland"). The new force was established on 1 April 2013.
In 2017, plans were being debated in the Scottish Parliament to merge railway policing with Police Scotland.
As of December 2012, police numbers in Scotland were:
- Police officers: 17,436
- Special constables: 1,404
- Other staff: 6,168
Community Support Officers, commonly referred to as "Police Community Support Officers", were established by Section 38(2) of the Police Reform Act 2002, which applies only to England and Wales. There are therefore no Community Support Officers in Scotland.
County and borough based police forces were not formed in Ireland as they were in Great Britain, with instead a single Royal Irish Constabulary covering most of Ireland (the exceptions being the Dublin Metropolitan Police, which was responsible for policing in Dublin, and the Belfast Town Police force, which was replaced by the RIC in the 1880s). The Royal Ulster Constabulary was formed in 1922 after the establishment of the Irish Free State, and served until the reforms of the police under the terms established initially by the Good Friday Agreement of 1998 undertaken by the Patten Commission, which led to the renaming of the RUC in 2001. The Police (Northern Ireland) Act 2000 sets out the basis for the organisation and function of the police force in the province. Until 2010, police powers were not transferred to the devolved Northern Ireland Executive, unlike Scotland, instead remaining with the Northern Ireland Office. However, in January 2010 agreement was reached between the two largest parties in the Assembly, the DUP and Sinn Féin, over a course that would see them assume responsibility for policing and justice from April.
As of April 2007 police numbers in Northern Ireland were:
- Police officers: 7,216
- Full-time reserve police officers: 335
- Part-time police officers: 684
- Other staff: 2,265
Police in Northern Ireland do not employ Police Community Support Officers
County police forces traditionally bore the name "constabulary" upon their formation (as a derivation of "constable"). The reorganisation of police forces over the years has seen this name dropped in favour of "police" as a name, as many have decided that the word "constabulary" is confusing for people more used to searching for the word "police". However, a number of police forces in the areas overseen by the United Kingdom retain the name "constabulary":
- 12 territorial forces in England
- 1 special police force - Civil Nuclear Constabulary
- 1 territorial force in the crown dependencies
- 1 parks police force (under the terms of the Parks Regulation Act 1872)
National law enforcement
Bodies with police powers
These bodies operate in more than one county of the United Kingdom. The remit of some of the forces is further limited to the areas that they police, such as railway infrastructure. The Anti-terrorism, Crime and Security Act 2001 gave the British Transport Police and Ministry of Defence Police a limited, conditional authority to act outside of their primary jurisdiction if the situation requires urgent police action and the local force are not readily available, or if they believe that there is risk to life or limb, or where they are assisting the local force.
- Government agencies
- National Crime Agency (NCA) – An agency that leads UK-wide activities to combat high-level crime such as organised crime. In addition, the NCA acts as the UK point of contact for foreign law enforcement agencies. It replaced the Serious Organised Crime Agency in 2013.
- Border Force is a part of the Home Office, responsible for frontline border control operations at air, sea and rail ports in the United Kingdom. Employees of Border Force may be Immigration Officers and/or customs officers. They hold certain powers of arrest, detention and search in addition to those available to Any person in England and Wales or to any person in Scotland and Northern Ireland. Police-like powers are exercised by border officers and inland immigration enforcement officers.
- Immigration Enforcement The agency also has a specialist criminal investigations directorate.
- Her Majesty's Revenue and Customs. Since the creation of the UK Border Agency (now Border Force), staff of HMRC no longer perform frontline duties at ports of entry. The remainder of the staff with law enforcement powers employed by HMRC consists of the Criminal Investigation Branch, who, as customs officers, continue to exercise the powers granted under the Customs Management Acts and the Police and Criminal Evidence Act 1984 including arrest.
- Environment Agency Fisheries Enforcement Officers/Water bailiffs have powers of a constable under the Salmon and Freshwater Fisheries Act 1975. Officers/bailiffs protect fish and combat related crime (e.g. poaching).
Additionally, the following three government agencies are defined in legislation as "special police forces". As these forces are responsible to specific areas of infrastructure, they do not answer to the Home Office, but instead to the government department responsible for the area they police. All three forces do voluntarily submit themselves to HMIC inspection:
- Ministry of Defence Police – A police force tasked with providing armed security, uniformed policing, and investigative services to Ministry of Defence installations throughout the United Kingdom.
- Civil Nuclear Constabulary – A police force responsible for providing law enforcement and security at or within 5 km of any relevant nuclear site and for nuclear materials in transit within the United Kingdom.
- British Transport Police (Great Britain) – A police force responsible for providing law enforcement at certain railways and light-rail systems in Great Britain.
- Bodies hosted by the Association of Chief Police Officers
- National Wildlife Crime Unit – A police unit run by the ACPO that gathers intelligence on wildlife crime and provides analytical and investigative support to law enforcement agencies across the United Kingdom.
- National Counter Terrorism Security Office – A police unit run by the ACPO, which advises the British government on its counter terrorism strategy.
- National Vehicle Crime Intelligence Service – A police unit run by the ACPO, tasked with combating organised vehicle crime and the use of vehicles in crime.
- Bodies hosted by territorial police forces
- National Domestic Extremism and Disorder Intelligence Unit – A police unit that is part of the Metropolitan Police Service Specialist Operations Directorate, tasked with coordinating police response to domestic extremism across the United Kingdom.
- Protection Command – A police unit that is part of the Metropolitan Police Service Specialist Operations Directorate, responsible for providing protective security to the government/diplomatic community and the Royal Family within the United Kingdom.
- National Fraud Intelligence Bureau – A police unit hosted by the City of London Police, tasked with combating economic crime throughout the United Kingdom.
- National Ballistics Intelligence Service (Great Britain) – A police unit hosted by West Midlands Police, tasked with gathering and disseminating fast time intelligence on the criminal use of firearms across Great Britain.
- National Police Air Service (England and Wales) – A police aviation service hosted by West Yorkshire Police, that provides centralised air support to the 43 territorial police forces in England and Wales.
Bodies with limited executive powers
These organisations are not police forces but do have similar powers to that of the police with the exception that they cannot arrest a person nor make forcible entry without a warrant.
- Driver and Vehicle Standards Agency (Great Britain)
- Driver and Vehicle Agency (Northern Ireland)
- The Independent Police Complaints Commission (England and Wales) investigates complaints against police officers and staff of the police forces in England and Wales, and staff of HM Revenue and Customs, the National Crime Agency in England and Wales and the Border Force. Certain investigators of the IPCC, for the purposes of the carrying out of an investigation and all purposes connected with it, have all the powers and privileges of constables throughout England and Wales and the territorial waters.
Bodies with solely investigatory powers
The use of investigatory powers is controlled by the Regulation of Investigatory Powers Act 2000. Up to 792 public authorities have powers that are restricted by RIPA.
- Office for Security and Counter-Terrorism
- Security Service
- Serious Fraud Office (England and Wales and Northern Ireland)
Miscellaneous police forces
These police forces generally come under the control of a local authority, public trusts or even private companies; examples include some ports police and the Mersey Tunnels Police. They could have been established by individual Acts of Parliament or under common law powers. Jurisdiction is generally limited to the relevant area of private property alone and in some cases (e.g. docks and harbours) the surrounding area. This, together with the small size of the police forces, means they are often reliant on the territorial force for the area under whose jurisdiction they fall to assist with any serious matter. The statutory responsibility for law and order sits with the territorial police forces even if there is a specialist police force in the locality. These police forces do not have independent Police Authorities and their founding statutes (if any) do not generally prescribe their structure and formation.
There are two types of port police in the United Kingdom — most are sworn in under the 1847 Act, but a few have Acts specific to their port.
- Ports police operating under the Harbours, Docks, and Piers Clauses Act 1847
For every port/harbour, an individual Act of Parliament (or, more recently, a Harbour (Revision) Order) can incorporate parts of the Harbours, Docks, and Piers Clauses Act 1847 (HDPCA) and apply them to that specific port/harbour. Officers of port police forces are sworn in as "special constables" under section 79 of the 1847 Act, as incorporated by the individual local Act. As a result, officers have the full powers of a constable on any land owned by the harbour, dock, or port and at any place within one mile of any owned land.
The Marine Navigation Act 2013 has potentially enabled ports contables in England & Wales to act as constables beyond this one mile limit, in relation to policing purposes connected with the port only, in a police area where consent has been obtained from the relevant Chief Constable. This act does not however give general police powers to ports constables beyond their core jurisdiction as set out in the 1847 act, merely in relation to policing purposes connected to the port as set out in the Act. As of 2014, 3 ports police forces (Dover, Teesport and Bristol) have sought and received consent from the local Chief Constable, with a fourth (Liverpool) in the process of applying for it. This has enabled these 3 ports forces to act as constables, in relation to policing purposes connected to the port, throughout the police area in which they are geographically located. There are 224 constables sworn in under the 1847 Act. Serious or major incidents or crime generally become the responsibility of the local territorial police force.
- Belfast Harbour Police — Belfast Harbour, Belfast: HDPCA incorporated by section 5 of the Belfast Harbour Act 1847.
- Larne Harbour Police — Larne Harbour Ltd, Larne.
- Port of Bristol Police — Port of Bristol, Bristol. Includes Avonmouth Dock, Bristol, Royal Portbury Dock, North Somerset, and 3 islands in the Bristol Channel: Denny Island, Flat Holme, Steep Holme.
- Port of Felixstowe Police — Port of Felixstowe, Suffolk: HDPCA incorporated by section 3(1)(e) of the Felixstowe Dock and Railway Act 1956.
- Port of Portland Police — Portland Harbour, Isle of Portland: HDPCA incorporated by section 3 of the Portland Harbour Revision Order 1997.
- Falmouth Docks Police — Falmouth Docks, Falmouth, Cornwall: HDPCA incorporated by section 3 of the Falmouth Docks Act 1959.
- Port of Dover Police — Port of Dover, Dover: HDPCA incorporated by section 3 of the Dover Harbour Consolidation Act 1954, and incorporation amended by part 4 of the Dover Harbour Revision Order 2006. Given the large amount of property owned by the port, their jurisdiction effectively extends to all of Dover and now throughout Kent (in relation to port policing matters only) in order to be able to take arrested persons to Custody Suites.
- Other ports police
- Port of Liverpool Police — Port of Liverpool, Liverpool: current authority derives from article 3 of the Mersey Docks and Harbour (Police) Order 1975. Port of Liverpool police officers are Crown police officers and not special constables.
- Port of Tilbury Police (formerly the Port of London Authority Police) — Port of Tilbury, Essex: current authority derives from section 154 of the Port of London Act 1968
- Tees and Hartlepool Port Authority Harbour Police — Tees and Hartlepool: current authority derives from section 103 of the Tees and Hartlepool Port Authority Act 1966
- A large, new port on the Thames Estuary (and within the Port of London area) called "London Gateway" is currently under construction, and the owners have the authority to create their own police force for the port. The legislation also incorporates S.79 of the 1847 Act.
- Parks not controlled by local authorities
These small constabularies are responsible for policing specific land and parks. Officers of these forces have the powers of a constable within their limited jurisdiction. They are not constables as dealt with in the general Police Acts.
- Epping Forest Keepers
- Current powers derive from regulations made under Epping Forest Act 1878
- Kew Constabulary (formerly Royal Botanic Gardens Constabulary)
- Constables of this force have full police powers whilst on land belonging to the Royal Botanical Gardens as per the Parks Regulation Act 1872 as amended by section 3 (a) of the Parks Regulation (Amendment) Act 1974.
- Parks controlled by local authorities
Over history, a number of local authorities outside London have maintained their own parks police forces, the most notable being Liverpool (Liverpool Parks Police) and Birmingham (Birmingham Parks Police). No local authority parks police forces currently exist outside London, although the legal powers for them to do so (granted by various local Acts of Parliament) survive in a limited number of cases.
In London, these constabularies are responsible for enforcing byelaws within the parks and open spaces of their respective local authorities. Members of the constabularies are sworn as constables under article 18 of the Greater London Parks and Open Spaces Order 1967. Members of the constabularies are constables only in relation to the enforcement of the parks byelaws (which, by definition, apply only in the parks).
- Parks Police Service, created through the merger of Hammersmith and Fulham Parks Constabulary and Royal Borough of Kensington and Chelsea Parks Police in 2013.
- Hampstead Heath Constabulary, also appointed under the Corporation of London opens spaces act sec 16, 1878 with the full powers and privileges of a Police Constable.
- Hillingdon Parks Patrol Service
- Wandsworth Parks and Events Police
Some of these constables have (or have had) a shared role as security staff for their own local authority's buildings and housing estates with appropriate changes of badges and/or uniform being made when changing to/from park duties.

Each branch of the military has its own police service, though the powers of a service police officer are identical and recipricol across all three services. The service police is made up of the:
- including the Royal Marines Police
In the UK, the service police exercise jurisdiction over those serving in the military in any capacity and those civilians subject to service discipline as defined by the Armed Forces Act 2006. They are not 'constables' and do not have any policing powers in relation to the general public in normal circumstances. In British Forces Germany, under the Status Of Forces Act, military police have jurisdiction over British Forces personnel, their families, MOD contractors, and NAAFI staff.
Service Police are PACE trained and all investigations are PACE compliant. They make regular use of civilian police facilities often conducting joint investigations where necessary. The Service Police are able to investigate all crime within their jurisdiction, up to and including Murder, however within the UK, offences of murder and sudden deaths are passed to the local police force as per national jurisdiction agreements.
Whilst operating in conflict zones the military police will conduct the full range of policing including murder investigations as evidenced by the Sgt Blackman investigation.

The Police aux Frontieres also maintain a presence at passport control at the Eurotunnel terminal in Folkestone and at Dover port, whilst Kent Police maintains a presence at Coquelles on the French side of the tunnel. Similar arrangements allow the Border Force to operate juxtaposed controls in France and Belgium.
