Grievous Bodily Harm (GBH)
Grievous bodily harm is one of the most serious assault charges. A conviction under Section 20 carries up to five years' imprisonment, and how your defence is handled from the first contact with police can determine the outcome.
About Grievous Bodily Harm (GBH)
Grievous bodily harm (GBH) under Section 20 of the Offences Against the Person Act 1861 is charged where a person unlawfully and maliciously wounds or inflicts grievous bodily harm upon another person. Grievous bodily harm means really serious harm — broken bones, injuries requiring surgery, deep lacerations, permanent scarring, or injuries causing long-term functional impairment. A wound specifically requires a break in both layers of the skin.
Section 20 GBH is an either-way offence carrying a maximum sentence of five years' imprisonment on indictment. It is distinguished from Section 18 (wounding with intent) by the mental element required. For Section 20, the prosecution must prove that the defendant foresaw that some physical harm might result from their actions — they do not need to prove an intention to cause serious injury. This lower threshold means that a single punch which causes a fractured jaw, or a push that results in a serious fall, can lead to a GBH charge.
Sentencing for Section 20 GBH varies significantly based on the nature of the injury, the level of force used, and whether any weapons were involved. At the lower end, suspended sentences or community orders may be appropriate. At the higher end, sentences of three to four years' custody are common. Aggravating factors include group attacks, use of weapons, vulnerability of the victim, and offences committed while on bail or under the influence of alcohol or drugs.
The defence to a Section 20 charge often centres on the level of harm caused, the intent behind the defendant's actions, and whether self-defence applies. A case charged as GBH may properly be an ABH if the injuries, while real, do not reach the threshold of really serious harm. Equally, if the defendant did not foresee that any harm would result — for example, where an injury was genuinely accidental — the mental element of the offence is not made out.
Key Points
- Charged under Section 20 of the Offences Against the Person Act 1861
- Either-way offence with a maximum of five years' imprisonment on indictment
- Requires proof that the defendant foresaw some physical harm might occur
- Covers both wounding (breaking of the skin) and inflicting grievous bodily harm
- Injuries must amount to really serious harm — broken bones, surgical wounds, lasting damage
- Distinguished from Section 18 by the absence of intent to cause serious harm
Why Early Representation Matters
The medical evidence is the foundation of every GBH case. We obtain and scrutinise the medical reports, hospital records, and photographs to assess whether the injuries genuinely meet the threshold of really serious harm. Where they do not, we make representations to the CPS to reduce the charge to ABH — a significantly less serious offence with a lower sentencing range.
We also focus on the circumstances of the incident itself. CCTV footage, witness accounts, and forensic evidence often tell a different story from the one presented by the prosecution. In many cases, the defendant was acting in self-defence, was responding to provocation, or was involved in a mutual altercation where both parties were equally responsible. Presenting that context clearly and persuasively is essential.
Frequently Asked Questions
The key difference is intent. Section 20 requires only that the defendant foresaw some harm might occur. Section 18 requires proof that the defendant intended to cause really serious harm. This distinction is enormously important: Section 20 carries a maximum of five years, while Section 18 carries a maximum of life imprisonment. Section 18 is indictable only, meaning it must be tried in the Crown Court.
GBH means really serious harm. This includes broken bones, dislocated joints, injuries requiring surgery, deep wounds needing stitches, permanent scarring or disfigurement, and injuries causing lasting impairment of function. There is no exhaustive list — the question is whether the injury is serious enough to justify the label.
Yes. If a single punch causes really serious injury — for example, a fractured eye socket, a broken jaw, or a serious head injury from falling after being struck — the charge can be GBH even though only one blow was struck. The charge reflects the injury caused, not the number of blows delivered.
Sentencing depends on the seriousness of the injury, how the offence was committed, and your previous record. The guidelines provide a range from community orders for the least serious cases up to four years and six months' custody for the most serious Section 20 offences. Aggravating factors such as use of a weapon, group violence, or attacking a vulnerable person push the sentence upward.
No. Section 20 GBH is an either-way offence and can be tried in either the Magistrates' Court or the Crown Court. The decision depends on the severity of the case and whether the magistrates consider their sentencing powers (up to six months) to be sufficient. More serious cases are almost always sent to the Crown Court. Section 18 GBH (with intent) is always tried in the Crown Court.
