The law is about defined images, not a genre label
People use 'extreme' in ordinary speech for many kinds of media. The criminal law asks a narrower set of questions about the image and the jurisdiction. Section 63 of the Criminal Justice and Immigration Act 2008 makes possession of an extreme pornographic image an offence in England, Wales and Northern Ireland. The section has been in force since 2009, with later amendments including the 2015 expansion. It is not a UK-wide single test. Scotland's section 51A of the Civic Government (Scotland) Act 1982 is its own offence, in force since 2011.
The House of Commons Library explains the existing definition: an image must be pornographic, extreme under the statutory criteria, and fall within a specified category. That is more precise than whether a viewer finds it offensive or whether a website calls it BDSM. This guide keeps descriptions non-graphic. It is general legal information, not legal advice; an individual image requires assessment against the law in force at the place and time of conduct.
Is pornography banned in the UK?
No. There is no blanket UK ban on lawful adult pornography. The House of Commons Library briefing explains that the law prohibits defined material, rather than every adult image. In England, Wales and Northern Ireland, the in-force section 63 possession offence concerns images meeting its statutory definition of extreme pornography. Scotland has its separate in-force section 51A offence. The categories and exceptions below matter more than a website label.
Some material is illegal for reasons other than the extreme-image definition, including child sexual abuse imagery. CPS guidance for England and Wales also distinguishes possession from publication and addresses obscene publications. Access rules for adult websites are a separate issue: an age check does not certify that every image is lawful. The existing sections below explain the nation-specific offences and the commencement position of the 2026 provisions; do not assume a prospective change is already in force.
The section 63 categories
For England, Wales and Northern Ireland, section 63 requires a pornographic image that is grossly offensive, disgusting or otherwise obscene and depicts specified acts explicitly and realistically. In plain terms, its categories include threats to life, serious injury to specified body areas, sexual interference with a human corpse, sexual acts with an animal, and non-consensual penetrative sexual acts. Section 37 of the Criminal Justice and Courts Act 2015 added the latter non-consensual penetration categories. These are statutory descriptions; this site gives no visual examples or search terms.
The precise elements matter. A disturbing plot summary is not automatically an image satisfying the section; nor does the presence of consenting adults make every image outside the law. The court considers whether the image appears realistic under the statutory test. Other laws may apply to creation, sharing, abuse or material involving children, and the absence of a section 63 offence is no general legality certificate. For an actual file, avoid circulating it to ask strangers for an opinion. A solicitor can explain how the current law and evidence apply.
Scotland uses its own possession offence
Section 51A of the Civic Government (Scotland) Act 1982 criminalises possession of extreme pornography in Scotland. It was inserted by section 42 of the Criminal Justice and Licensing (Scotland) Act 2010 and commenced in March 2011. The Commons Library notes that Scotland's provision included depictions of non-consensual penetrative sexual activity from its introduction, whereas Westminster legislation added equivalent categories in 2015. The tests and defences must still be read in their own texts; one cannot simply transplant an England and Wales case summary to Scotland.
The Crown Office and Procurator Fiscal Service describes Scottish sexual-offence and pornography context. An investigation can raise issues outside this possession offence, such as how an image was obtained or whether the people shown agreed to distribution. If an image involves abuse of a real person, support for that person is a distinct need from the possessor's legal question. Intimate images and digital consent covers the separate question of permission to record and share.
Defences are fact-specific
Section 65 lists general defences for the England, Wales and Northern Ireland offence, including legitimate reason, not knowing or having reason to suspect the nature of an unseen image, and an unsolicited image not kept unreasonably long. Section 66 addresses a specific participation defence with conditions. The Commons Library also discusses a particular defence concerning apparent non-consensual imagery. These are legal tests with burdens and details, not a self-certification form or permission to collect files.
If an unsolicited file arrives, do not forward it or build a private archive 'for evidence' without advice. Record the sender and context safely if necessary and ask an appropriate professional how to preserve evidence without further harm. The response may differ if someone is being threatened or a crime against a child is suspected. A genuine education, research or law-enforcement context has its own evidential questions; casually calling a file 'research' does not establish a legitimate reason. Scotland has separate statutory provisions, so seek jurisdiction-specific advice.
What the 2026 Act would add
Section 104 of the Crime and Policing Act 2026 would insert a new section 67A into the 2008 Act concerning possession or publication of pornographic images of strangulation or suffocation in England, Wales and Northern Ireland. Section 105 makes the corresponding Scottish provision. Legislation.gov.uk showed both sections as prospective, not yet in force when checked on 3 October 2026. Do not describe a proposed new section 67A offence as an operational offence today. Existing laws may still apply to the conduct or image.
The Act's explanatory notes describe a realistic-image test and the separate possession and publication aspects. These details should not be merged into the older section 63 definition. The statute also contains other pornography provisions in sections 106 and 107; their scope and commencement are separate and are not asserted here as currently in force. See the law and medical risk of non-fatal strangulation for conduct and care, which remain important regardless of an image offence's commencement.
Possession, publication and platform rules differ
Possession concerns an image held by a person; publication concerns making material available to others. Online-service duties and criminal offences can also differ. The existence of a platform age check does not mean every item on that platform is lawful, consensual or safe. The Online Safety Act guide explains why adult sites ask for age assurance, without treating an age gate as an endorsement of the contents beyond it.
Private desire, depicted action, a recording and a file sent onward are separate matters. If a person is in a film without permission to copy or share it, intimate-image offences and support routes may matter even if the extreme-pornography test is not met. Conversely, a purportedly consensual production is not an automatic answer to a section 63 question. Do not upload disputed material to a public forum or a chatbot for classification. An adviser can review the facts and the current statutory version privately.
The Simon Walsh trial (2012)
In 2012, a jury acquitted Simon Walsh of section 63 extreme-pornography charges. His defence solicitor’s contemporary account reports the outcome. The charge concerned section 63 of the Criminal Justice and Immigration Act 2008, the possession offence applying in England, Wales and Northern Ireland and still in force, as checked on 9 October 2026.
The case is cited in Backlash’s evidence submitted to Parliament when criticising uncertainty over the offence’s boundaries. That is the campaign’s interpretation, not a finding that the jury abolished the law or approved every category of imagery. An acquittal decides the charges against that defendant; it does not repeal section 63. No unpublished reasoning is attributed to the jury. The landmark-cases timeline distinguishes verdicts, binding judgments and legislative changes.
The 2025 Independent Pornography Review
Baroness Bertin’s Independent Pornography Review, published in February 2025, recommended making pornography depicting non-fatal strangulation illegal to possess, distribute and publish. A review recommendation is not itself an offence. The official explanatory notes to the Crime and Policing Act 2026 identify the review and explain how the Act takes its recommendations forward.
Section 104 provides new possession and publication offences for strangulation or suffocation imagery in England, Wales and Northern Ireland; section 105 provides the Scottish counterpart. On 9 October 2026, legislation.gov.uk still marked the new offence provisions as prospective: enacted, but not yet in force. Section 104’s separate Online Safety Act amendment has its own commencement position. The existence of the Act must not be confused with commencement of every offence. Existing extreme-pornography law continues to apply, and the 2026 Act changes guide explains the wider framework.
Common questions about the possession rules
Is all BDSM imagery prohibited? No; the law specifies elements and categories. Does an adult age check make possession lawful? No. Does an image have to be a photograph? The statute defines image more broadly; check the operative text. Is the Scottish test exactly the same as section 63? No. Does an actor's agreement always settle the issue? No; the specific statutory defences and other offences still require separate analysis.
Is section 67A currently in force? Not as checked on 3 October 2026: the 2026 Act sections creating it remained prospective. What if a file was sent without request? Section 65 has a particular defence, but the time kept and other facts matter. Why not list prosecution thresholds here? They can change and depend on the image, conduct and jurisdiction. A dated official source is more useful than a simplified screenshot of this page.
UK help and legal advice
For a legal question about possession or publication, consult a solicitor in the relevant UK nation. Citizens Advice can help identify an advice route in England and Wales; Scotland and Northern Ireland have their own Citizens Advice networks and legal services. If an intimate image of you has been circulated, the Revenge Porn Helpline offers support to adults, and UK help lists further routes. Call 999 in immediate danger.
