Prison Officer Powers and Legal Authority in England and Wales

In shortThere is no single powers statute: authority comes from the Prison Act, the Prison Rules, common law and statute on force and search, and HMPPS frameworks.

The phrase "while acting as such" matters. Constable powers attach to the officer's work as a prison officer, not to the person at all times. Our prison officer ranks and grades guide explains who counts as an officer in HMPPS terms.

Prison Act 1952

The foundation. Section 7 says every prison shall have a governor, a chaplain and such other officers as may be necessary; section 8 says every prison officer while acting as such shall have all the powers, authority, protection and privileges of a constable.

Prison Rules 1999

Made under the Act; they govern the daily regime, discipline, searching and use of force.

HMPPS policy frameworks and instructions

Tell staff how to apply the Act and the Rules.

Case law, common law and the Human Rights Act 1998

Matter especially on force and self-defence. The Use of Force Policy Framework (re-issued 11 September 2025) lists the Criminal Law Act 1967, Prison Rule 47 and Young Offender Institution Rule 50, the Criminal Justice and Immigration Act 2008, common law and the European Convention on Human Rights as the basis for force in prisons.

In shortArrest is lawful under PACE but HMPPS treats it as an exceptional step: call the police wherever an arrest is being considered.

The Searching Policy Framework (re-issued 31 March 2026) says arrest powers must only be used in accordance with the Police and Criminal Evidence Act 1984 (PACE) codes of practice, with codes C, G and H relevant.

A constable may arrest without warrant under section 24 PACE for any offence, but only where there are reasonable grounds to suspect an offence and reasonable grounds to believe arrest is necessary for one of the listed reasons, such as to prevent injury or damage, to protect a child or vulnerable person or to allow prompt and effective investigation.

The framework warns that lack of knowledge and training can lead to incorrect procedures. It says prison officers exercising arrest powers should receive the same training as police officers, and that in all but exceptional circumstances the best course is to contact the police to attend.

1. Contact the police to attend any situation where an arrest is being considered; arrangements must be made for an arrested person to be taken to a police station as soon as possible.
2. Tell the arrested person they are arrested and why, and caution them unless impracticable.
3. Write down any response.
4. Explain that no questioning by prison staff will occur.
5. Make sure they remain until the police arrive.

In shortSearching has strict legal limits: no intimate searches by staff, no stripping in sight of another prisoner or the opposite sex, and no force against a prisoner who refuses to squat.

Prison Rule 41 says every prisoner shall be searched when taken into custody by an officer, on reception into a prison and subsequently as the governor thinks necessary or the Secretary of State directs, in as seemly a manner as is consistent with discovering anything concealed.

No prisoner shall be stripped and searched in the sight of another prisoner or a person of the opposite sex.

Section 8A of the Prison Act 1952 gives an "authorised person" at a prison the power to search any prisoner for unauthorised property. They cannot require removal of clothing other than an outer coat, jacket, headgear, gloves and footwear, may use reasonable force where necessary and may seize and detain unauthorised property.

Full search

Removal of clothing and visual observations.

Rub down search

Outer clothing removed, contact search over clothing and visual observations.

Technical aids

Metal detectors and scanners.

Men's estate

Prisoners may be rub-down searched by male or female staff but must only be full searched by male prison officers.

Women's estate and under-18s

Prisoners must not be full searched as a matter of routine, and must never be asked to squat; squatting is also not permitted in the under-18 estate.

Intimate searching

Outside officers' authority. HMPPS does not permit it to include direct removal of an item by a member of staff, or ordering a prisoner to remove an item themselves, and staff do not have legal authority to intrude into bodily orifices. Where staff believe an item is internally concealed, this must be relayed to healthcare, and staff must never remove the item themselves. Force should never be used if a prisoner refuses to squat.

• The staff governors should authorise: prison officers and operational managers, prisoner custody officers, instructional officers, stores and catering staff, agricultural and horticultural craftsmen and operational support grades.

In shortForce must be necessary, reasonable and proportionate, and the legal provisions are defences to a criminal charge, not positive permissions.

Prison Rule 47 is short and central. An officer in dealing with a prisoner shall not use force unnecessarily and, when the application of force is necessary, no more force than is necessary shall be used. And no officer shall act deliberately in a manner calculated to provoke a prisoner.

The framework stresses that the provisions below are not positive permissions for individuals to use force; they are defences to a criminal charge.

Common law

Force may be used where necessary for self-defence or defence of another, preventing imminent self-harm, preventing damage to prison property, preventing escape, preventing crime and, when essential, maintaining order.

Section 3, Criminal Law Act 1967

Reasonable force to prevent crime or to arrest offenders.

Section 76, Criminal Justice and Immigration Act 2008

Defence of self, others and property, judged on the facts as the accused believed them if the belief was genuinely and reasonably held.

Article 3 of the Convention

Prohibits inhuman or degrading treatment whatever the circumstances. Examples of breaches: using PAVA on a prisoner already brought under control, using batons on a prisoner who refused to leave his cell, or any retaliatory or excessive force.

In shortSome of the strongest criminal law in prisons is about what is brought in, and staff are themselves subject to it.

Sections 40B to 40D of the Prison Act 1952 create offences for conveying prohibited articles into or out of prison, and for unauthorised photography, transmitting from inside and possessing specified electronic devices. Authorisation can be granted by the Secretary of State or the Governor and must be recorded.

Staff themselves are subject to these provisions, which is why contraband and mobile phone cases feature so heavily in discipline.

In shortThe Prison Rules set expectations as well as powers: firmness without excess restriction, leadership by example and rehabilitation.

That is the legal root of the "rehabilitative culture" language in HMPPS policy, and it affects how powers are used. The use of force review published on 24 April 2025 adds that how force is used and explained afterwards is a central part of fairness and legitimacy.

Rule 6

Order and discipline shall be maintained with firmness but with no more restriction than is required for safe custody and well-ordered community life. Officers should seek to influence prisoners through their own example and leadership and enlist their willing co-operation, and discipline and control should foster self-respect and personal responsibility.

Rule 3

The purpose of training and treatment of convicted prisoners is to encourage and assist them to lead a good and useful life.

In shortThe law protects officers from assault, and every use of force is recorded, reviewed and open to external scrutiny.

• Assaults on staff9,83312 months to March 2026 (MoJ)
• Classed as serious871Same period
• Record on DPSWithin 24 hoursEvery use of force
• StatementWithin 72 hoursFrom free recall, before viewing footage

The Assaults on Emergency Workers (Offences) Act 2018 lists prison officers among emergency workers.

A person who commits common assault or battery against one is liable on summary conviction to imprisonment up to the magistrates' court general limit, a fine or both, and on conviction on indictment to up to 2 years. See prison officer assault statistics.

Accountability sits alongside protection. Every use of force must be recorded on the Digital Prison Service within 24 hours and each involved staff member must complete a statement within 72 hours, written from free recall before viewing CCTV or body-worn footage.

• Governors must hold a monthly use of force committee reviewing footage and statements and all uses of PAVA and batons.
• The Prisons and Probation Ombudsman, investigators and the courts can all review what was done.
• If you are interviewed under caution or formally investigated, take advice from your union and read POA representation in disciplinary cases.

In shortNot everyone in a prison has the same powers, and everything here is the law of England and Wales only.

Scotland and Northern Ireland have separate prison legislation and policy, which we have not set out here. If you are applying to the Scottish Prison Service or the Northern Ireland Prison Service, read their own guidance.

• Prisoner custody officers in private prisons are certified under the Criminal Justice Act 1991 and, because section 8 of the Prison Act does not apply there, rely on powers in that Act, such as the search and force powers in sections 82 and 86. See prison custody officer in private prisons and prison escort officer.
• Operational support grades can be authorised to carry out rub-down searches under section 8A but are a different grade; see operational support grade role.
