What Is Actual Bodily Harm (ABH) in Criminal Law?

Actual bodily harm, usually shortened to ABH, is a criminal offence in England and Wales covering an assault that causes physical or psychiatric injury going beyond the trivial but falling short of really serious harm. It is charged under Section 47 of the Offences Against the Person Act 1861 and carries a maximum sentence of five years in prison.¹ Because the law only requires intent behind the initial assault and not the resulting injury, people are sometimes surprised to find themselves facing an ABH charge for what started as a shove or a single punch.

What Counts as Bodily Harm

The working definition comes from a 1934 decision, R v Donovan, which described bodily harm as any hurt or injury that interferes with a person’s health or comfort and is more than merely transient and trifling. The injury does not need to be permanent, and it does not need to be particularly serious. It just has to be real enough that it cannot be shrugged off as trivial.

Psychiatric harm can also qualify, but only if it amounts to a clinically recognised condition. Ordinary fear, anxiety, or distress after an assault does not meet the threshold. A diagnosable condition such as post-traumatic stress disorder or clinical depression, caused directly by the assault, can.¹

Injuries That Typically Lead to an ABH Charge

The Crown Prosecution Service publishes a charging standard that helps prosecutors decide whether an injury warrants ABH or stays within common assault. Grazes, scratches, minor bruising, reddening of the skin, and superficial cuts usually stay in common assault territory. Injuries that typically cross into ABH include:²

Damaged teeth or bones, such as a chipped tooth, a broken nose, or a fractured finger
Extensive or severe bruising, not just a minor mark
Cuts deep enough to need stitches
Loss of consciousness, even briefly

Context matters as well. A black eye from a punch in a domestic setting, for example, may be charged as ABH rather than common assault because of the circumstances around the offence.²

What the Prosecution Has to Prove

A conviction requires two things. First, that the defendant committed an assault or battery. Second, that this assault or battery caused actual bodily harm.

An assault here means intentionally or recklessly making someone fear immediate unlawful violence. Battery means intentionally or recklessly applying physical force to another person, however slight. Recklessness is enough: a defendant who did not mean to scare or touch anyone but acted in a way a reasonable person would recognise as risky can still be convicted.²

The point that catches most defendants off guard is the mental element. The prosecution does not need to prove the defendant intended to cause the injury. They only need to prove the defendant intended or was reckless about the underlying assault or battery. Push someone during an argument, meaning only to move them aside, and they fall and break a wrist? That is enough for ABH. You intended the push. The broken wrist followed from it.

Where ABH Sits Between Common Assault and GBH

English law treats assault offences on a sliding scale based on how much harm the victim suffers. Common assault, under Section 39 of the Criminal Justice Act 1988, covers minor force or making someone fear an imminent attack, with little or no injury. The maximum sentence is six months.¹

ABH is the middle tier, with its five-year maximum, and it is an either-way offence. That means it can be heard in a magistrates’ court or in the Crown Court depending on severity.²

Above ABH sits grievous bodily harm. Section 20 GBH covers really serious physical harm, including wounding, which legally means breaking the skin. Section 18 GBH requires proof that the attacker intended really serious harm and carries a maximum of life imprisonment.¹

How ABH Is Sentenced

The Sentencing Council guideline asks courts to weigh two things: how blameworthy the offender was (culpability) and how serious the harm was. Culpability runs in three bands.³

High (Category A): significant planning, use of a highly dangerous weapon, strangulation, targeting a vulnerable victim, leading a group attack, or a prolonged assault
Medium (Category B): use of a weapon that does not reach Category A, a lesser role in a group attack, or cases falling between high and lesser culpability
Lesser (Category C): no weapon used, excessive self-defence, a spontaneous and short-lived assault, or an offence linked to a mental disorder or learning disability

Starting points track those bands. The most serious cases (Category 1, Culpability A) start at two years and six months in custody with a range of 18 months to four years. Mid-range cases start at 36 weeks in custody with a range from a high-level community order to 18 months. The least serious start at a medium-level community order with a range from a fine to 26 weeks in custody.³

Racially or Religiously Aggravated ABH

When an ABH offence is motivated by racial or religious hostility, or the offender demonstrates that hostility during or immediately after the attack, the charge is upgraded under Section 29 of the Crime and Disorder Act 1998. The maximum sentence rises from five years to seven.⁴ The aggravating factor can turn what might otherwise be a community order into a substantial prison sentence.

Defences

Self-Defence

Self-defence is the most commonly raised defence to an ABH charge. Under Section 76 of the Criminal Justice and Immigration Act 2008, the court asks two questions: did the defendant genuinely believe force was necessary, and was the amount of force used reasonable in the circumstances as the defendant believed them to be?⁵

The law accepts that someone acting in the heat of the moment cannot calibrate their response perfectly. If a person did what they honestly and instinctively thought was necessary, that is strong evidence the force was reasonable. The force must not be disproportionate to the threat, though. There is no formal duty to retreat, but whether the defendant could have walked away is something a court can weigh. If force goes beyond what was reasonable, the Sentencing Council treats that as lesser culpability rather than a full defence, which usually produces a lighter sentence rather than an acquittal.³

Consent

Consent is a far narrower defence than most people assume. As a general rule, a person cannot legally consent to being harmed at the level of ABH or above. Two people who willingly agree to a fistfight can both be charged with ABH, regardless of their mutual agreement. The principle was confirmed in R v Brown in 1993.

Some recognised exceptions survive even when ABH results:

Properly conducted sports, where participants in contact sports like rugby or boxing implicitly consent to the physical harm that comes with the game
Reasonable surgical procedures carried out with informed consent
Cosmetic procedures such as tattoos and piercings
Horseplay, where rough but good-natured physical play lets consent be implied

Outside these narrow categories, consent will almost never succeed.

Life After an ABH Conviction

A conviction produces a criminal record that can affect employment, particularly in roles requiring Disclosure and Barring Service (DBS) checks such as working with children, healthcare, or financial services. Travel to some countries, notably the United States, can also become harder, because assault convictions may trigger visa refusal or denial of entry under visa-waiver programmes. These consequences often outlast the sentence itself.

One boundary worth flagging: ABH is a concept specific to English and Welsh law, with closely related forms in Northern Ireland, Australia, and other Commonwealth jurisdictions. The United States does not use the term, classifying similar conduct instead under assault and battery statutes that vary by state.
