Common assault: the threshold that starts at fear and three ways to defend it
SaveCommon assault is the least serious form of assault in English law, but it still creates a criminal record and can result in custody. It covers both threatened violence and minor physical contact, requiring no visible injury. HS Criminal Law walks you through what counts as common assault, how courts treat it and the defences that might apply to your situation.
The two forms of common assault
Common assault divides into two actions: assault by causing someone to fear immediate unlawful violence, and battery, which is the actual unlawful application of force. Raising a fist in someone's face can be assault without any contact; pushing, grabbing or slapping is battery. Both are charged under the same offence, and both require intention or recklessness.
Immediate means the victim must believe the violence will happen now, not at some future point. A threat over the phone or by text rarely meets this test. Unlawful excludes force the law permits, such as reasonable chastisement by parents within tight limits, or self-defence.
What separates common assault from ABH and GBH
The injury is the dividing line. Common assault involves no injury or very minor harm that needs no medical treatment—a red mark that fades quickly, slight grazing, temporary discomfort. Assault occasioning actual bodily harm (ABH) begins where the injury is more than transient or trivial: bruising, cuts that require stitches, or psychological harm diagnosed by a professional. Grievous bodily harm involves serious injury such as broken bones, wounds requiring surgery, or lasting impairment.
| Offence | Injury threshold | Maximum sentence |
|---|---|---|
| Common assault | None, or transient marks | Six months custody |
| Assault occasioning ABH | More than trivial harm | Five years custody |
| Wounding or GBH | Serious injury | Life imprisonment |
Where the harm sits on this spectrum determines which charge the Crown Prosecution Service brings. Police often arrest for common assault when the injury is unclear, then the charge is reviewed once medical evidence arrives.
Intention and recklessness
Prosecution must prove you intended the assault or were reckless—that you saw the risk of causing fear or applying force and went ahead anyway. Accidental contact is not common assault: stumbling into someone on a crowded train, or knocking a glass from their hand while gesturing in conversation, lacks the required state of mind.
Words alone can negate an apparent assault. Saying "I'd hit you if the police weren't here" shows you do not intend immediate violence. Actions and context matter more than the words used: advancing toward someone with a raised fist while shouting almost always satisfies the test, regardless of what is said.
Three defences to common assault
Self-defence and defence of another
You may use reasonable force to protect yourself, someone else, or your property from unlawful violence. The force must be proportionate to the threat you honestly believed you faced. Courts assess what you thought at the time, not what a calmer observer would have done. If you struck first because you genuinely believed an attack was about to happen, that can be self-defence.
Reasonable is judged on the circumstances. A single push to create distance is more likely to succeed than repeated punches after the threat has passed. Retaliation after the danger has gone is not defence.
Consent
Where both parties agree to the contact, there is no assault. This covers contact sports, medical treatment, and everyday jostling. The law does not recognise consent to actual bodily harm or worse outside narrow exceptions such as surgery or properly regulated sport. For common assault, if the other person agreed to what happened—rough play between friends, for instance—it is a defence, provided the force stayed within what was agreed.
Lawful correction
Parents and those acting in loco parentis may use reasonable physical correction of a child, but the scope has narrowed. It must be minor, leave no mark, and never involve implements or blows to the head. Most physical discipline now risks prosecution, and the defence rarely succeeds where injury is visible.
Charges, court and penalties
Common assault is a summary-only offence, meaning it stays in the magistrates' court. You may be charged after arrest, summonsed to court without arrest, or given a conditional caution that avoids court if you admit the offence and meet certain conditions.
Magistrates can impose up to six months' custody, though most first offenders receive a fine, a community order, or a conditional discharge. Aggravating factors push the sentence higher: assaulting someone vulnerable, domestic abuse, or committing the offence while on bail. The court will also consider whether to impose a restraining order to protect the victim.
The process from arrest to sentence
- Arrest or voluntary interview at the police station. You have the right to free legal advice—ask for the duty solicitor if you have no one arranged.
- Police investigation, including statements from the victim and any witnesses, photographs of injury, and your own account.
- Charge decision by police or the Crown Prosecution Service. You may be released under investigation, released on bail with conditions, or charged and bailed to court.
- First hearing at the magistrates' court, where you enter a plea. A duty solicitor can represent you on the day if you arrive without one.
- Trial or sentencing. If you plead not guilty, the case is listed for trial with witnesses; if guilty, the court sentences immediately or after a pre-sentence report.
Criminal records and disclosure
A conviction for common assault creates a criminal record that will appear on standard and enhanced DBS checks until it becomes spent. The rehabilitation period depends on the sentence: a fine or discharge becomes spent after one year, a community order after the order ends, and custody after the sentence plus a buffer period. Once spent, you do not have to disclose it to most employers, though certain roles require full disclosure even after rehabilitation.
When to get legal advice
If you have been arrested, charged or interviewed under caution for common assault, speak to a solicitor before you give any account to police. What you say in interview shapes the rest of the case. A solicitor can advise whether to answer questions, give a prepared statement, or stay silent. Legal aid covers criminal defence for most people interviewed or charged with an offence.
Where self-defence or another complete defence applies, early advice increases the chance that no charge is brought at all. Even where the facts are against you, a solicitor can negotiate with the Crown Prosecution Service for a lesser charge or a caution instead of prosecution.

Frequently asked questions
What is the legal definition of common assault in the UK?
Common assault is causing someone to fear immediate unlawful violence, or applying unlawful force to another person, where no injury or only transient harm results. It requires intention or recklessness and is the least serious assault offence.
How does simple assault differ from battery?
Assault is making someone fear immediate violence without touching them; battery is the actual application of unlawful force, however slight. Both fall under the single offence of common assault in English law.
Can you go to prison for common assault?
Yes. Magistrates can impose up to six months' custody for common assault, though most first-time offenders receive a community order, fine or conditional discharge. Custody is more likely where there are aggravating factors such as domestic abuse or targeting a vulnerable victim.
