The legally limited role consent may play when an activity causes injury. A private agreement does not automatically provide a defence to assault, and rules depend on harm, purpose, recognised exceptions and jurisdiction.

In brief
Consent has legal limits once injury crosses relevant thresholds.
In England and Wales, section 71 of the Domestic Abuse Act 2021 restates that a person cannot consent to actual bodily harm or more serious injury for sexual gratification, reflecting R v Brown. This principle is not limited to domestic relationships. Scotland and Northern Ireland have their own law and case context, so an England-and-Wales summary must not be generalised across the UK.
England and Wales
Section 71 states that consent is not a defence to inflicting serious harm for sexual gratification and treats actual bodily harm or worse as serious harm for this purpose. It also addresses consent to one's own death.
Charging and injury classification remain fact-specific. Bruising, cuts, unconsciousness and other effects cannot be assigned a safe legal category by a glossary.

Jurisdiction
UK overview: England and Wales, Scotland, and Northern Ireland may differ
Read the rest: evidence, law, safety and sources
Personal consent
Agreement between participants, essential ethically but not always a complete legal defence to injury.
Battery or common assault
Lower-level unlawful force, where consent can operate differently depending on facts and jurisdiction.
Actual bodily harm
In England and Wales, harm more than transient or trifling, engaging the statutory sexual-gratification limit.
Recognised exception
Contexts such as properly conducted sport or medical treatment governed by specific legal principles.
Consent and criminal liability
Ethical negotiation, safewords and risk disclosure remain important but cannot contract out of criminal law. Written waivers do not guarantee legality.
Consent to sexual activity is also separate from consent to a particular injury. Freedom, capacity, scope and withdrawal still matter.
Jurisdiction and changing facts
Scotland and Northern Ireland do not simply apply section 71 as England and Wales do. Their statutes, common law and prosecutorial decisions require separate analysis.
Location, conduct, resulting harm, intention and evidence all matter. Online advice based only on labels such as BDSM or rough sex is unreliable.
Practical safety
Avoid treating a hoped-for injury threshold as a safety target. Medical danger can precede visible injury, especially with breathing restriction, head impact or internal trauma.
For an actual injury, prioritise healthcare and truthful information. Obtain criminal-law advice from a qualified lawyer for a specific incident or planned high-risk event.
