Being accused of indecent exposure is a serious matter that can result in imprisonment and placement on the Sex Offenders Register. This guide explains the law under Section 66 of the Sexual Offences Act 2003, including recent changes under the Crime and Policing Bill 2025, sentencing guidelines, and how allegations are proven.
In Brief
- Offence: Indecent exposure is defined under Section 66 of the Sexual Offences Act 2003 as intentionally exposing your genitals with intent to cause alarm or distress
- Maximum Sentence: 2 years’ imprisonment in the Crown Court (12 months in Magistrates’ Court)
- Key Element: The prosecution must prove specific intent - that you meant for someone to see your genitals and be caused alarm, distress, or (under the 2025 changes) humiliation
- Sex Offenders Register: Required if convicted and sentenced to 12+ months, given any prison term, or where the victim was under 18
What is Indecent Exposure?
Indecent exposure, often called “flashing,” is a criminal offence under Section 66 of the Sexual Offences Act 2003. A person commits this offence if they:
- Intentionally expose their genitals, AND
- Intend that someone will see them and be caused alarm or distress
This is a crime of “specific intent.” The prosecution must prove not just that you exposed yourself, but that you did so deliberately with the intention of causing someone distress. Accidental exposure - such as being seen while changing - does not meet the legal threshold for this offence.
2025 Legal Changes
The Crime and Policing Bill 2025 has significantly expanded this offence. Under the new provisions, indecent exposure also includes:
- Exposing genitals with intent to cause humiliation (not just alarm or distress)
- Exposing genitals for sexual gratification while being reckless as to whether someone who sees will be caused alarm, distress, or humiliation
This means prosecutors no longer need to prove you specifically intended distress - recklessness while seeking sexual gratification is now sufficient.
What Counts as Indecent Exposure?
The law specifically requires exposure of the genitals. Other body parts, including buttocks or breasts, do not fall within Section 66 (though may constitute other offences).
Common examples of indecent exposure include:
- Flashing: Deliberately opening clothing to reveal genitals to a stranger
- Public masturbation: Exposing genitals while performing sexual acts
- Streaking: Running naked through a public place
- Window exposure: Standing naked at a window intending to be seen
The offence can occur in any location - public or private - as long as there is intent for someone to see and be caused distress.
Indecent Exposure vs Outraging Public Decency
These are separate offences often confused:
Factor | Indecent Exposure | Outraging Public Decency |
|---|---|---|
Law | Sexual Offences Act 2003, s.66 | Common law offence |
Requirement | Exposure of genitals | Any act of a lewd, obscene, or disgusting nature |
Intent | Must intend to cause alarm/distress | Must know or be reckless that public could witness |
Maximum | 2 years’ custody | Unlimited fine, 12 months’ custody (Magistrates’) |
Sex Offender Register | Yes (if criteria met) | No |
Outraging public decency is broader and can include acts that do not involve genital exposure, such as sexual acts in public or displaying offensive material. Prosecutors sometimes charge outraging public decency when the specific intent for indecent exposure cannot be established.
How is Indecent Exposure Proven?
To secure a conviction, the prosecution must prove:
- The defendant exposed their genitals - typically through witness testimony, CCTV footage, or admissions
- The exposure was intentional - not accidental or unavoidable
- The defendant intended someone to see - the exposure was directed at one or more people
- The defendant intended to cause alarm or distress - or, under the 2025 changes, humiliation or sexual gratification with recklessness
Key Evidence Types
- Witness testimony from the person who saw the exposure
- CCTV or phone footage capturing the incident
- Police body-worn camera evidence
- Forensic evidence in cases involving touching
- Pattern evidence showing repeated behaviour targeting the same location or type of victim
The prosecution may rely on circumstantial evidence. For example, if someone repeatedly exposed themselves to lone women at the same bus stop, this pattern would be strong evidence of intent.
Indecent Exposure Sentencing Guidelines
Sentencing follows the Sentencing Council guidelines (revised 1 April 2024). The offence is triable either way - in Magistrates’ Court or Crown Court depending on seriousness.
Sentencing Categories
Category | Description | Starting Point | Range |
|---|---|---|---|
1 | Raised harm AND raised culpability | 26 weeks’ custody | 12 weeks’ - 1 year |
2 | Raised harm OR raised culpability | High-level community order | Medium community order - 26 weeks’ custody |
3 | Neither raised harm nor culpability | Medium-level community order | Band A fine - High community order |
Aggravating Factors (Raised Culpability)
- Previous convictions for sexual or relevant offences
- Targeting a vulnerable victim
- Victim followed or pursued
- Offender masturbated during exposure
- Threats or intimidation used
- Abuse of trust
- Racially or religiously aggravated
- Children present or likely to be present
Mitigating Factors
- No previous convictions
- Clear expression of genuine remorse
- Mental health condition affecting judgement
- Evidence the incident was out of character
- Early guilty plea (up to one-third reduction)
Maximum Sentences
- Magistrates’ Court: 12 months’ custody
- Crown Court: 2 years’ custody
Can You Be Charged in Your Own Home?
Yes. Indecent exposure can occur anywhere if the legal elements are met.
If you deliberately stand at a window naked, intending for passers-by to see and be distressed, this can constitute indecent exposure. The key question is whether you intended to be seen and to cause distress.
However, simply being visible while undressed in your home - for example, walking past a window - is unlikely to meet the threshold if there was no intent to be observed or cause distress. Context matters significantly.
Is Public Urination Indecent Exposure?
Not usually. Urinating in public is generally prosecuted under different legislation:
- Section 5 Public Order Act 1986 (disorderly behaviour)
- Local authority byelaws (anti-social behaviour)
- Environmental Protection Act 1990 (littering in some areas)
For public urination to become indecent exposure, the prosecution would need to prove you exposed your genitals with the specific intent of causing someone alarm or distress - not simply relieving yourself.
That said, urinating in view of others (particularly in a targeted way) could potentially support an indecent exposure charge if the circumstances suggest deliberate intent to distress. Each case turns on its facts.
What Defences Are Available?
Several defences may apply depending on the circumstances:
Lack of Intent
The prosecution must prove you intended to cause alarm, distress, or humiliation. If the exposure was accidental or you genuinely believed no one could see you, you may have a defence.
Mistaken Belief About Location
If you reasonably believed you were in a private place where no one could see (for example, a secluded changing area), this may negate the required intent.
Mental Health Conditions
While not a complete defence, mental illness affecting your understanding or control at the time may be relevant to sentencing and may support arguments against conviction in some cases.
Duress
If you were forced or threatened into exposing yourself, this may provide a defence.
Naturism
Simply being a naturist is not a defence. However, if you genuinely and reasonably believed you were in a designated naturist area, this may be relevant to intent.
Police Caution vs Court Conviction
If you admit the offence, the police may offer a caution instead of prosecution. This is more common for first-time, lower-level incidents.
Key Differences
Outcome | Sex Offenders Register | Criminal Record | DBS Check |
|---|---|---|---|
Police Caution | Generally NO | Yes | Yes (never filtered*) |
Court Conviction (community order under 12 months) | NO (unless victim under 18) | Yes | Yes |
Court Conviction (12+ months or custody) | YES | Yes | Yes (indefinite) |
*Indecent exposure is a “specified offence” under DBS filtering rules. This means cautions for this offence for adults are never filtered and will always appear on standard and enhanced DBS checks, regardless of how much time has passed.
A caution may seem attractive, but it often creates a permanent record that will appear on DBS checks indefinitely. You should always seek legal advice before accepting a caution.

Frequently Asked Questions
What is the punishment for indecent exposure for a first offence?
For a first offence with no aggravating factors, you would typically fall into Category 3, which has a starting point of a medium-level community order. This might include unpaid work, a curfew, or supervision. A fine is possible for the least serious cases. Custody is unlikely unless aggravating factors are present.
Is flashing someone a criminal offence in the UK?
Yes. Flashing - deliberately exposing your genitals to someone with intent to cause alarm or distress - is the criminal offence of indecent exposure under Section 66 of the Sexual Offences Act 2003. It carries a maximum sentence of 2 years’ imprisonment.
Do you go on the Sex Offenders Register for indecent exposure?
Often, but not automatically. You will almost always go on the SOR if you receive a custodial sentence, community order or if your victim was under 18. However, in certain circumstances, a minor conviction may not lead to registration.
Can you be charged with indecent exposure for urinating in public?
It is possible but unusual. Public urination is typically charged as disorderly behaviour or a byelaw offence. For an indecent exposure charge, prosecutors would need to prove you intended to cause alarm or distress by exposing your genitals - not simply that you needed to relieve yourself. Intent is the key distinction.
How long does indecent exposure stay on your record?
A conviction for indecent exposure stays on your criminal record permanently. However, for disclosure purposes (jobs, travel), the rehabilitation period depends on your sentence. Following the October 2023 changes: - A fine becomes “spent” after 1 year - A community order becomes spent when the order ends - A custodial sentence of 12 months or less becomes spent after the sentence length plus 1 year.
For adults, Sex Offenders Register requirements (if applicable) last from 5 years to life depending on sentence length. Note that indecent exposure cautions for adults are never filtered from DBS checks as it is a specified offence.
What is the difference between indecent exposure and public indecency?
“Public indecency” is not a specific offence in English law - it is a general term. The closest offence is outraging public decency, which is broader and covers any lewd or disgusting act in public, not just genital exposure. Indecent exposure under Section 66 specifically requires exposing genitals with intent to cause alarm or distress. Outraging public decency does not require you to register as a sex offender; indecent exposure potentially does.
