Policing in the UK: Current structures and proposals for reform

How is policing structured in the UK?

All police officers (no matter their rank) hold the office of constable. It is from the ‘office of constable’ that each officer derives their powers, such as powers to search and detain people. They are expected to use their powers without fear or favour or improper political interference.

Every police constable is a member of a police force, led by a chief constable. Police forces are operationally independent from government and Parliament. This means that police officers should make decisions about criminal investigations and the use of their powers without political interference.

England and Wales are divided into 43 policing areas. These are:

• the Metropolitan Police Service (covering most of London) and the City of London Police (covering areas controlled by the City of London Corporation)
• 37 other police forces in England
• four police forces in Wales

Police Scotland and the Police Service of Northern Ireland (PSNI) are the police forces for Scotland and Northern Ireland.

There are also three specialist police forces, responsible for the railway network, civil nuclear sites and Ministry of Defence sites.

How do police forces work together?

Police forces must coordinate their efforts when investigating crimes across borders, responding to major public order events or tackling particularly complex and serious crime.

Some police forces enter into collaboration agreements with other forces to pool their resources, enhance cooperation and achieve economies of scale.

‘Mutual aid’ agreements enable police forces to loan their officers to another force to help manage increased demand, for example to respond to large scale protests or disorder. Police forces also work with the National Crime Agency to tackle serious and organised crime in the UK.

The National Police Chiefs’ Council is the co-ordinating body for all police forces in the UK and publishes policies and strategies on operational policing matters that are adopted by all police forces.

The College of Policing is the professional body for policing in England and Wales and shares knowledge and good practice within the policing community.

Who oversees the work of the police?

The Home Secretary is responsible for allocating funding, setting national policing priorities and managing legislation relating to policing structures and powers. 

Local elected policing bodies (either a police and crime commissioner or a regional mayor) set budgets for each force, determine local priorities and scrutinise their chief constables.

HM Inspectorate of Constabulary and Fire & Rescue Services (HMICFRS) provides independent scrutiny of police performance and the Independent Office for Police Conduct is responsible for maintaining public confidence in the police complaints system in England and Wales.

There are different structures in Scotland and Northern Ireland.

How does the government propose reforming policing structures?

In January 2026, the Home Office published a white paper on police reform, From local to national: a new model for policing. In the King’s Speech 2026, the government committed to introduce a Police Reform Bill to implement commitments in the white paper.

The proposals include significantly reducing the number of police forces in England and Wales, by merging existing forces into larger regional police forces. The government does not propose what the new geographies of these larger forces will be. Instead, it has set up an independent review that will propose the best way to organise regional police forces.

In addition, the government proposes merging the National Crime Agency, College of Policing and the National Police Chiefs’ Council into a new National Police Service, which will lead on serious and organised crime and counter terrorism. The National Police Service would be led by a chief constable called the National Police Commissioner.

The proposed changes would represent the biggest reform to policing structures in England and Wales since the 1960s and ‘70s, when Parliament legislated to merge the old patchwork of forces into the current 43-police force model.

Some senior police officers have previously called for reforms to the existing model. For example, in his Annual Assessment of Policing in England and Wales 2024–25, Andy Cooke, the then HM Chief Inspector of Constabulary, said the 43-police force model system leads to “inefficiencies, duplication and inconsistencies”. Both Sir Mark Rowley, Metropolitan Police Commissioner and Gavin Stephens, Chair of the National Police Chiefs’ Council have also argued for major reforms to the policing model.

Shabana Mahmood, Home Secretary, announced the white paper in an oral statement to Parliament on 26 January 2026. In response, Chris Philp, Shadow Home Secretary, said police force mergers would not help tackle increases in crimes such as shoplifting and phone theft. He said “Regional mega-forces will make things worse, not better.”

How else does the government propose reforming policing?

The white paper makes several other proposals for reforming policing, including to:

• scrap police and crime commissioners and establish new policing and crime boards (made up of mayoral authorities and council leaders)
• give a new power to HMICFRS to issue “directions” to police forces that fail to implement recommendations
• re-establish a power for the Home Secretary to force a chief constable to resign or retire
• require police officers to hold a “licence to practice”, which will involve mandatory training requirements for officers to continue to serve
• deliver a police national workforce strategy, with a focus on ensuring recruitment of both neighbourhood police officers and specialists that can support the police to respond to modern threats

More broadly, the paper signals a greater willingness for the Home Office to take a “hands on” approach to policing, by setting national guarantees and priorities underpinned by targets. A police performance framework has been published alongside the paper.

The government says these changes are necessary to respond to falling public confidence in the police, poor police performance and to changing patterns in crime.
