ABH vs GBH: Charges, Intent, and Sentencing Ranges

ABH and GBH are the two main assault charges above common assault in England and Wales, and when comparing ABH vs GBH the distinction turns on two things: how serious the injury was, and what the defendant intended. ABH (actual bodily harm) under Section 47 of the Offences Against the Person Act 1861 covers harm that is more than trivial but short of really serious. GBH (grievous bodily harm) under Section 20 covers really serious injury or a wound that breaks both layers of skin. Both carry a maximum of five years’ custody. Section 18, which is GBH with intent, carries a maximum of life imprisonment.¹

Where the Injury Line Falls

Common assault sits below both charges and covers grazes, scratches, minor bruising, reddening of the skin, and superficial cuts.² Anything more than that starts to look like ABH.

For ABH, the injury must be more than “transient and trifling,” a test drawn from the 1934 case of R v Donovan that prosecutors still apply.² It doesn’t have to be permanent. The CPS treats the following as typically crossing the ABH threshold:

Damaged teeth or broken bones
Extensive or severe bruising
Cuts requiring stitches
Loss of consciousness

ABH also covers psychiatric injury, but only where there is a clinically recognised psychiatric illness backed by medical evidence.² Fear, panic, or general upset does not qualify. A diagnosis of PTSD or clinical depression can.

GBH under Section 20 covers injuries that are “really serious.” The statute creates two routes into a Section 20 charge: inflicting grievous bodily harm, and wounding.³ Wounding requires a break in both layers of the skin, so a deep laceration from a knife or a bottle counts, while internal bleeding on its own usually does not. Grievous bodily harm looks at the overall seriousness of the injury regardless of whether the skin is broken. Broken limbs, permanent disability, visible disfigurement, injuries needing surgery or a blood transfusion, and the transmission of a serious disease all fall into GBH territory.

The Intent Question: Section 20 vs Section 18

The injury alone does not decide whether GBH is charged under Section 20 or Section 18. That comes down to what the prosecution can prove about the defendant’s state of mind.

For Section 20, the mental element is lower than most people expect. The prosecution does not need to prove the defendant meant to cause serious harm. It only needs to show the defendant acted “maliciously,” which courts read as foreseeing that some physical harm might result and going ahead anyway. A single punch that shatters a jaw can meet Section 20 if the person throwing it foresaw any risk of physical harm.

Section 18 is the most serious assault charge short of attempted murder. The injuries may look identical to those in a Section 20 case, but the prosecution has to prove the defendant specifically intended to cause really serious harm, or intended to resist or prevent a lawful arrest.¹ Prosecutors build that case from the full picture: whether a weapon was used, how many blows were struck, whether the attack continued after the victim was on the ground, and anything the defendant said before or during the assault. A single punch in a pub argument rarely meets the Section 18 threshold. A sustained attack with a weapon, or stamping on someone’s head, usually will.

How Prosecutors Choose the Charge

The CPS works through the decision in two stages. First, prosecutors assess the level of injury using medical evidence, photographs, and witness accounts. That places the case in the common assault, ABH, or GBH band.²

Second, they look at the surrounding circumstances. Where an injury sits close to the line between two bands, factors like the use of a weapon, a vulnerable victim, repeated conduct, significant premeditation, or a domestic abuse context can push the charge up.² The CPS has stated a commitment to robust charging in domestic abuse and hate crime cases, and prosecutors lean toward the more serious charge when those features are present.

Sentencing Ranges Compared

The maximum sentence is only the ceiling. Judges in England and Wales follow Sentencing Council guidelines that place each offence on a grid of harm and culpability, running from Category 1A (most serious) to Category 3C (least serious).

ABH (Section 47)

The maximum is five years’ custody.² Guideline sentences run from a fine up to four years:⁴

Category 1A: starting point 2 years 6 months (range 1 year 6 months to 4 years)
Category 2B: starting point 36 weeks (range high-level community order to 1 year 6 months)
Category 3C: starting point medium-level community order (range Band B fine to 26 weeks)

GBH (Section 20)

The maximum is also five years’ custody, which catches many people off guard given the injuries are more serious than ABH.² Guideline sentences sit higher within that cap:⁵

Category 1A: starting point 4 years (range 3 to 4 years 6 months)
Category 2B: starting point 2 years (range 1 to 3 years)
Category 3C: starting point 26 weeks (range medium-level community order to 1 year)

GBH With Intent (Section 18)

The maximum is life imprisonment, and the guideline sentences jump sharply:⁶

Category 1A: starting point 12 years (range 10 to 16 years, with extreme cases going higher)
Category 2B: starting point 5 years (range 4 to 7 years)
Category 3C: starting point 3 years (range 2 to 4 years)

A Category 1A offence starts at 4 years under Section 20 and at 12 years under Section 18. Identical injury, identical category. The three-fold difference is entirely about proven intent.

What Pushes a Sentence Up or Down

After placing a case on the grid, judges adjust based on the facts. The Sentencing Council identifies statutory aggravating factors courts must treat as increasing seriousness:⁴

Relevant previous convictions, weighed by how similar the past offence was and how recent
Committing the offence while on bail
Hostility toward the victim’s race, religion, disability, sexual orientation, or transgender identity, which courts must state publicly
Assaulting an emergency worker acting in their role

Common mitigating factors include a lack of prior convictions, genuine remorse, provocation, mental health difficulties at the time of the offence, and a lesser role in the incident. A first-time defendant who acted impulsively in an emotionally charged moment will usually receive a lighter sentence than someone with a violent history who planned the attack.

Which Court Hears the Case

ABH and Section 20 GBH are “either-way” offences, tried in either the Magistrates’ Court or the Crown Court.² Magistrates handle less complex cases and have a lower sentencing ceiling; where they consider the facts too serious for their powers, they send the case up to the Crown Court.

Section 18 GBH with intent is indictable-only, so it must be tried in the Crown Court before a judge and jury.² The Crown Court holds the full sentencing powers, including the life sentence Section 18 allows.

Self-Defence

Self-defence is a complete defence to any assault charge, including ABH, Section 20, and Section 18, if the court accepts the force used was reasonable. The tests are whether you honestly believed force was necessary and whether the level of force was reasonable in the circumstances. The law accepts that people in frightening situations cannot weigh their response to the nearest gram, and doing only what you honestly thought was necessary at the time is strong evidence you acted within the law.⁷ You do not have to wait to be attacked before defending yourself.

The defence fails where force clearly goes beyond what was needed: continuing to attack someone already on the ground, setting a deliberate trap instead of calling the police, or starting the fight in the first place.
