Breathing restriction needs urgent assessment
If someone's breathing has been restricted, stop immediately and seek emergency medical care, even if they say they feel fine or show no marks. Call 999 for breathing difficulty, collapse, confusion, severe symptoms or immediate danger. Tell the clinician what happened and when; do not let embarrassment or fear about a relationship delay care. The NHS non-fatal strangulation advice explains that symptoms and serious complications can appear after the event, and an absence of visible injury is not reassuring.
A person may have trouble swallowing, a changed voice, pain, dizziness, headache, memory gaps or other symptoms. The clinical team needs the actual history to assess them. This guide deliberately gives no methods, pressure thresholds or claims about a 'safe' duration. Breathing restriction is dangerous even when intended as a consensual activity. If there is uncertainty about the urgency in a non-immediate situation, NHS 111 can direct care in England, Scotland and Wales; Northern Ireland has its own urgent-care routes. Do not use a phone triage route to postpone care for a breathing problem.
England and Wales: the specific offence
Section 75A of the Serious Crime Act 2015, inserted by section 70 of the Domestic Abuse Act 2021, creates the non-fatal strangulation and suffocation offence in England and Wales. It came into force on 7 June 2022. Its first limb addresses intentional strangulation; the second addresses an act affecting breathing that constitutes battery. Read the statutory wording and defences rather than treating the everyday phrase 'choking' as a legal definition. Other offences can also apply on the facts.
The CPS guidance emphasises that visible injury need not be present. Evidence may include a person's account, clinical records and other circumstances; none should be dismissed simply because an image of the neck looks normal. A claim about earlier agreement must be evaluated against the offence and facts. Section 71 of the Domestic Abuse Act 2021, also England and Wales, addresses purported consent to serious harm for sexual gratification and came into force on 29 April 2021. It does not replace section 75A.
Northern Ireland and Scotland have different rules
Northern Ireland's section 28 of the Justice (Sexual Offences and Trafficking Victims) Act (Northern Ireland) 2022 provides its own non-fatal strangulation offence. It came into operation on 26 June 2023. The Public Prosecution Service for Northern Ireland is the relevant prosecution authority. A reference to England and Wales section 75A alone does not describe the Northern Irish charge, statutory wording or commencement. Ask a Northern Ireland solicitor about a real case.
Scotland has separate criminal law on assault and sexual offences and prosecution by COPFS. The England and Wales section 75A and the Northern Ireland section 28 do not extend as freestanding Scottish offences. That does not mean harmful conduct is lawful in Scotland; the applicable charge depends on its law and evidence. The Scotland comparison introduces consent to sexual activity, a separate legal issue. Across all nations, obtain medical care first and disclose any ongoing threat to the care team.
Sentencing
For adults in England and Wales, the non-aggravated strangulation or suffocation offence under section 75A of the Serious Crime Act 2015 has a maximum of five years' imprisonment on indictment. The Sentencing Council definitive guideline confirms that maximum and gives the separate racially or religiously aggravated offence a seven-year maximum. The five-year figure must not be presented as a UK-wide maximum for every possible charge.
The England and Wales strangulation or suffocation guideline has been effective since 1 January 2025 and was verified on 7 October 2026. It applies to adults and assesses culpability and harm, with further adjustments under its sentencing steps. A maximum is not the sentence automatically imposed in an individual case. Northern Ireland and Scotland use their own offences and sentencing systems; seek nation-specific advice.
How consent and coercion are assessed
A relationship label, a prior conversation or a written agreement cannot certify that a person freely agreed to a particular act at a particular time. Someone who is frightened, incapacitated, pressured or trying to survive an assault may not be able to say no. The CPS guidance asks investigators to consider the entire context, including controlling behaviour and the possibility that a victim minimises an event. Do not demand that someone settle a legal label before taking them for care.
Where a person reports consensual intimacy, a clinician still needs the breathing history and symptoms. A medical assessment is not a declaration about criminal liability. Conversely, whether an offence is charged does not determine whether an injury is clinically serious. In England and Wales, section 75A has its own statutory terms and a limited consent-related defence; section 71 concerns specified serious-harm offences. The facts and jurisdiction matter. R v Brown explains the separate injury-law background without offering an individual verdict.
Evidence, privacy and practical support
A person may choose to tell a trusted friend, keep messages or note symptoms and times, if doing so is safe. They should not delay urgent treatment to make a record. Healthcare staff can document symptoms, assess urgent risk and discuss options. A survivor may be unsure about police involvement; specialist support can explain reporting choices without requiring an immediate decision. If someone else controls their device or monitors accounts, use a safe way to seek help.
If a friend tells you about restricted breathing, believe the urgency and help them reach care. Avoid interrogating them about why they were there, whether they had agreed before, or why they did not leave. Follow their wishes about privacy unless an immediate danger requires emergency action. The coercive control guide can help distinguish freely chosen dynamics from pressure. NHS care and support remain available whatever language a person uses for the relationship.
The separate 2026 image proposals
Section 104 of the Crime and Policing Act 2026 would insert a possession and publication offence for defined pornographic images of strangulation or suffocation in England, Wales and Northern Ireland. Section 105 makes the corresponding provision for Scotland. Legislation.gov.uk showed both as prospective, not yet in force, on 3 October 2026. The offences about images should not be confused with the already operative offence about conduct under section 75A.
Whether an image exists or is lawful has no bearing on the need for care after breathing restriction. Recording or distributing an intimate image can raise other consent and criminal-law questions; the digital consent guide treats those separately. The legislation's commencement pages should be checked again before citing a new image offence as law in force. This distinction matters because enactment at Royal Assent does not mean every section commenced at once.
Common questions about injury and law
No bruise means no danger? No: serious complications can follow without visible marks. Should I wait for a symptom to get help? No, seek emergency medical care after any breathing restriction. Is section 75A the law in Scotland? No. Does Northern Ireland have a separate offence? Yes, from June 2023. Are the 2026 image sections already offences in force? They remained prospective on the date checked. Does a safeword make an unsafe event medically safe? No.
What if a person cannot remember exactly what happened? Tell clinicians what is known and what is uncertain; memory gaps can themselves matter clinically. What if I fear being judged? Health staff need information about breathing, voice, swallowing and consciousness, not a polished story. Can this page assess a charge? No: a solicitor needs the case facts and the law in force at the relevant place and time.
UK emergency care and legal help
Call 999 for immediate danger or serious symptoms, and seek emergency medical assessment after any breathing restriction. The NHS domestic-abuse support page and UK help give support routes. Rape Crisis services can support survivors of sexual violence; a domestic-abuse service can help make a safety plan. In Northern Ireland or Scotland, use local NHS/HSC and specialist support routes appropriate to the nation.
The glossary has entries for breath play, risk profile, capacity to consent and consent to bodily harm. None makes breathing restriction medically safe.
For a criminal-law question, read section 75A, the Northern Ireland section 28, and current CPS guidance, then speak to a solicitor. Citizens Advice can direct people to advice. A guide cannot decide guilt, consent or a clinical diagnosis. This is legal information, not legal advice.
