In Brief
Being accused of possessing, making, or distributing indecent images of children (IIOC) is an extremely serious matter. The offences are governed primarily by Section 1 of the Protection of Children Act 1978 and Section 160 of the Criminal Justice Act 1988, with sentencing guided by the Sentencing Council’s definitive guidelines (revised April 2024). Images are classified into three categories: Category A (the most serious, involving penetrative sexual activity, sadism, or bestiality), Category B (non-penetrative sexual activity), and Category C (other indecent images).
Maximum sentences range from 5 years’ custody for simple possession up to 10 years’ custody for making or distributing images. Early legal advice from an experienced criminal defence solicitor is essential if you are under investigation or have been charged.
What Are Indecent Images of Children (IIOC)?
Indecent images of children, commonly referred to as IIOC, are photographs or pseudo-photographs of anyone under 18 that are deemed indecent. The law covers digital images, videos, computer-generated images, and tracings or derivatives of photographs.
The main criminal offences are:
- Taking or making an indecent image of a child (Section 1, Protection of Children Act 1978) – maximum: 10 years’ custody
- Distributing or showing indecent images (Section 1, PCA 1978) – maximum: 10 years’ custody
- Possessing an indecent image of a child (Section 160, Criminal Justice Act 1988) – maximum: 5 years’ custody
- Possessing with a view to distribution (Section 1, PCA 1978) – maximum: 10 years’ custody
Importantly, “making” has been broadly interpreted by the courts. It does not require physically creating an image. Downloading from a website, opening an email attachment, saving to a device, or receiving an image via social media can all constitute “making” an indecent image where the person knows of, or suspects, the nature of the image.
How Are Indecent Images Categorised?
The Sentencing Council uses a three-tier classification system to assess the seriousness of indecent images. The category of images involved is one of the most significant factors in determining the sentence.
Category | Description | Seriousness |
Category A | Images involving penetrative sexual activity, sexual activity with an animal, or sadism | Most serious |
Category B | Images involving non-penetrative sexual activity | Mid-range |
Category C | Other indecent images not falling within Category A or B (including erotic or sexual posing) | Least serious |
Where a defendant possesses images across multiple categories, the court will sentence based on the most serious category present. The volume of images and the spread across categories will also influence the sentence.
What Are the Sentencing Guidelines for Indecent Images?
The Sentencing Council’s definitive guidelines for indecent images of children, most recently revised on 1 April 2024, set out starting points and ranges for each offence type and category.
The sentencing ranges below are guideline starting points. The actual sentence will depend on culpability, harm, the volume of material, and aggravating or mitigating factors.
Possession of Indecent Images (CJA 1988, s.160)
Category | Starting Point | Range |
Category A | 1 year’s custody | 26 weeks – 3 years’ custody |
Category B | 26 weeks’ custody | High-level community order – 18 months’ custody |
Category C | High-level community order | Medium-level community order – 26 weeks’ custody |
Making or Taking Indecent Images (PCA 1978, s.1)
For “making” offences (including downloading), courts treat these with similar severity to possession for sentencing purposes. However, for offences involving the production (original creation) of indecent images, sentences are significantly higher:
Category | Starting Point | Range |
Category A | 6 years’ custody | 4 – 9 years’ custody |
Category B | 2 years’ custody | 1 – 4 years’ custody |
Other cases | 18 months’ custody | 1 – 3 years’ custody |
Distribution of Indecent Images (PCA 1978, s.1)
Category | Starting Point | Range |
Category A | 3 years’ custody | 2 – 5 years’ custody |
Category B | 1 year’s custody | 26 weeks – 2 years’ custody |
Other cases | 13 weeks’ custody | High-level community order – 26 weeks’ custody |
Additional Consequences
Beyond the custodial or community sentence, a conviction for IIOC offences will almost certainly result in:
- Notification requirements (commonly known as the Sex Offenders Register)
- A Sexual Harm Prevention Order (SHPO), which may restrict internet use or contact with children
- Being barred from working with children or vulnerable adults
- The conviction appearing on DBS checks – indecent image offences are “specified offences” and will typically appear on enhanced DBS disclosures, often bearing long-term implications for employment.
What About Pseudo-Photographs and AI-Generated Images?
The law also criminalises pseudo-photographs, which are images that appear to be photographs but are in fact created or altered digitally. This includes computer-generated imagery (CGI) and, increasingly, images produced by artificial intelligence.
Under the Coroners and Justice Act 2009 (Section 62), it is an offence to possess a prohibited image of a child. AI-generated images may be prosecuted as pseudo-photographs where they appear realistic, although this remains a developing area of law.
This is a rapidly growing area of concern. The Internet Watch Foundation (IWF) reported that in 2024, reports of actionable AI-generated child sexual abuse imagery increased by 380% compared to 2023. The Online Safety Act 2023, which came into force with enforcement powers from March 2025, places legal duties on online platforms to detect and remove child sexual abuse material, with fines of up to 10% of global turnover for non-compliance.
Aggravating and Mitigating Factors
The court will consider a range of aggravating and mitigating factors when determining the final sentence.
Aggravating factors (increasing the sentence):
- Previous convictions, particularly for sexual offences
- Offence committed while on bail or subject to a court order
- Very young age of the child depicted
- Large volume of images or videos
- Evidence of sharing within a network or online community
- Commercial motivation or financial gain
- Use of encryption, anonymisation, or steps taken to conceal offending
Mitigating factors (reducing the sentence):
- No previous convictions or relevant offending history
- Genuine remorse and co-operation with the investigation
- Mental health difficulties linked to the offending
- Steps taken to address behaviour (e.g., voluntary treatment)
- Early guilty plea (reducing the sentence by up to one-third)
What Defences Are Available?
Several statutory defences exist:
- Legitimate reason for possessing or distributing the images (e.g., law enforcement professionals)
- Unsolicited images – images received without prior request and not kept for an unreasonable time (e.g., malware or virus causing automatic downloads)
- Marriage/civil partnership defence – the image depicts a child aged 16 or 17 who was the defendant’s spouse or civil partner, and the child consented and/or the defendant reasonably believed there was consent
A defence may also arise where images were received unsolicited and not retained for an unreasonable time.
Courts are generally sceptical of defences based on “research purposes.” If you believe you have a valid defence, seek legal advice immediately to ensure evidence is preserved.
Recent Legal Developments
Several important changes have occurred since these offences were last reviewed:
- April 2024: The Sentencing Council revised its definitive guidelines for indecent images of children, updating various provisions including considerations for offender character and conduct.
- Online Safety Act 2023: Platforms now face legal duties to remove child sexual abuse material, with Ofcom actively enforcing compliance since March 2025. This has led to increased detection and referrals to law enforcement.
- Recent developments have increased the complexity of sentencing in indecent image cases, particularly around short custodial sentences and the use of suspended sentences. Courts must carefully consider whether custody is necessary in each case.
These developments mean that the sentencing landscape for IIOC offences is more nuanced than ever. Professional legal representation is essential to navigate the current framework.

Frequently Asked Questions
What is the minimum sentence for possession of indecent images?
There is no mandatory minimum sentence. For Category C possession, the starting point is a community order, so custody can be avoided. For Category A possession, the starting point is 1 year’s custody with a range of 26 weeks to 3 years. The actual sentence depends on the category, volume, and aggravating or mitigating factors.
Will I go to prison for indecent images?
It depends on the nature and seriousness of the offence. For lower-level possession offences (Category C), a community order is the likely starting point. Under the Sentencing Act 2026, there is now a presumption that sentences of 12 months or less should be suspended. However, for more serious offences involving Category A images, production, or distribution, an immediate custodial sentence is very likely.
How do police investigate indecent images?
Police typically uncover indecent images through online surveillance, intelligence from the National Crime Agency (NCA) and CEOP, referrals from internet service providers, and tip-offs. Devices will be seized and forensically examined. See our guide on how police uncover and investigate indecent images.
Do indecent image cases ever get dropped?
Yes. The CPS may decide not to proceed if there is insufficient evidence, if it is not in the public interest, or if a valid defence exists. Common reasons include evidence that malware caused the downloads or that the defendant was unaware of the images. Read more about how the CPS decides whether to charge.
Will an indecent images conviction show on a DBS check?
Yes. Indecent image offences are classified as “specified offences” and will always appear on enhanced DBS checks. They are never eligible for filtering, regardless of how much time has passed. This has long-term consequences for employment, particularly in roles involving children or vulnerable adults.
What is a Sexual Harm Prevention Order (SHPO)?
A SHPO is a court order imposed alongside or instead of a sentence. It may restrict internet access, require monitoring software on devices, prohibit contact with children, or limit travel. Breach of a SHPO is a criminal offence carrying up to 5 years’ custody.
