A comprehensive guide to indecent images offences under England and Wales law. Learn what constitutes indecent images, relevant laws like the Protection of Children Act 1978 and Criminal Justice Act 1988, how offences are classified and prosecuted, potential penalties, and practical considerations for reporting or seeking legal help.
Indecent images offences are a serious category of criminal law in England and Wales, especially where they involve children. These offences relate to taking, making, possessing, distributing or showing indecent sexual images, particularly of people under the age of 18, and are addressed through a combination of statutes and case law. This article explains the legal framework, key offences, how the law defines critical terms like “indecent” and “making”, the potential penalties, and what individuals and professionals should understand about how these cases are investigated and prosecuted. The aim is to provide clear, educational insight for members of the public, students, and legal practitioners.
What Does “Indecent Images” Mean in Law?
Legal Definition and Scope
The term “indecent” is not defined in statute. Courts and prosecutors assess whether an image is indecent based on its content, context and how a reasonable person would view it. This often includes sexual activity or suggestive sexual imagery.
Legislation relevant to indecent images includes:
- The Protection of Children Act 1978 (PCA 1978), which criminalises most acts involving indecent images of children.
- The Criminal Justice Act 1988 (CJA 1988), which creates an offence for possession of indecent images.
Both Acts apply in England and Wales and are supplemented by prosecutorial guidance and sentencing guidelines.
Who Is Protected by the Law?
The law regards a child as a person under 18 years of age. Any sexual images involving a person under this age are covered by indecent images offences.
This includes:
- Photographs and videos
- Pseudo‑photographs (computer‑generated or altered images that appear real)
Key Indecent Images Offences
1. Taking, Making, Showing or Distributing Indecent Images of Children
Under section 1(1) of the PCA 1978, it is an offence to:
- Take or permit the taking of an indecent image of a child
- Make or create such an image (including downloading or storing digitally)
- Distribute or show the image to others
- Possess the image with the intention of showing or distributing it
“Making” can include actions such as downloading an image, opening an attachment, or even causing the image to be displayed on a device.
2. Possession of Indecent Images
Under section 160 of the CJA 1988, it is a separate criminal offence simply to possess an indecent image of a child. This applies even if there is no evidence of intent to distribute or show the images.
3. Prohibited Images (Non‑Photographic)
The law also prohibits possession of non‑photographic prohibited images of children (for example cartoons or CGI) under the Coroners and Justice Act 2009, where the image is pornographic, sexual and grossly offensive.
Categories of Indecent Images
For investigation and sentencing, indecent images are often classified based on severity:
- Category A: Most serious, including sexual activity involving penetration, bestiality, or sadistic content.
- Category B: Non‑penetrative sexual activity.
- Category C: Sexually suggestive content or posing without explicit sexual activity.
These categories assist courts in determining appropriate sentences.
How the Law Is Applied
Making and Possession Explained
In law, “making” an image does not only mean creating it from scratch. It includes any act that results in a new copy of an indecent image, such as:
- Opening an email attachment containing the image
- Downloading images from a website
- Storing or accessing the image on a device
Possession means storing the image on any device or storage medium. Importantly, “possession” can arise even from viewing such images if a copy is saved in device memory.
Defences and Public Interest
There are limited statutory defences in some cases, such as where a defendant genuinely did not know the image was indecent or was unaware they possessed it. These defences are narrow and often difficult to establish.
In cases involving children creating or sharing images with peers, prosecuting authorities consider public interest factors - for example, whether the act was consensual and part of normal youthful behaviour. However, adults involved in images of children almost always face strict liability for the offences.
Penalties and Legal Consequences
Penalties for indecent images offences differ depending on the specific offence:
- Possession: Maximum of 5 years' imprisonment and/or a fine under the CJA 1988.
- Taking, making, distributing or showing: Maximum of 10 years' imprisonment under the PCA 1978.
Sentencing also considers aggravating factors such as the volume of images, involvement in distribution networks, and whether the offender held images in higher severity categories.
Convictions generally result in inclusion on the Sexual Offences Register and may attract ancillary orders such as Sexual Harm Prevention Orders.
Investigation and Prosecution
Police and specialist units investigate reports of indecent images offences. Digital forensics are often used to analyse devices and online accounts. The Crown Prosecution Service (CPS) reviews evidence and decides whether to bring charges in the public interest.
Cases can involve complex digital evidence, and individuals under investigation should consider obtaining qualified legal representation from solicitors experienced in sexual offences and digital forensic evidence.
Practical Considerations
Reporting Suspected Offences
If you encounter what may be indecent images of children online, you can report them to the Internet Watch Foundation (IWF) or directly to local police. Reporting preserves safety and supports investigation without exposing you to legal risk.
Legal Advice and Representation
If suspected of involvement in an indecent images investigation, it is important to seek specialist legal advice early. Criminal defence solicitors can advise on rights, evidence handling, bail, and potential defences.
