Offences Against Children Under 13 — Strict Liability
Children under 13 are treated by law as incapable of consenting to sexual activity. For offences in this category, consent is irrelevant and a defendant's belief about the child's age — however genuine — is not a defence. The principal offences are rape of a child under 13 (section 5 — life imprisonment), assault by penetration of a child under 13 (section 6 — life imprisonment), sexual assault of a child under 13 (section 7 — 14 years), and causing or inciting a child under 13 to engage in sexual activity (section 8 — life imprisonment where penetration is involved, 14 years otherwise).
| Offence | Section | Maximum Sentence |
|---|---|---|
| Rape of a child under 13 | s.5 | Life imprisonment |
| Assault by penetration — child under 13 | s.6 | Life imprisonment |
| Sexual assault of a child under 13 | s.7 | 14 years |
| Causing/inciting sexual activity — child under 13 (penetrative) | s.8 | Life imprisonment |
| Sexual activity with a child under 16 | s.9 | 14 years / 5 years (if under 18) |
| Arranging or facilitating a child sex offence | s.14 | 14 years |
| Meeting a child following grooming | s.15 | 10 years |
| Abuse of position of trust | ss.16-24 | 5 years |
Offences Against Children Aged 13 to 15 — The Reasonable Belief Defence
The age of consent in England and Wales is 16. Sexual activity involving a child aged 13, 14, or 15 is unlawful regardless of whether the child appeared to consent. However, unlike the under-13 provisions, these offences do allow for a defence based on reasonable belief in the child's age. To succeed, the defendant must demonstrate that they reasonably believed the child was 16 or older — the belief must be both genuine and objectively reasonable. The court will examine what steps were taken to verify the child's age and the information available at the relevant time.
Section 14 — Arranging and Facilitating, Including Sting Operations
Section 14 makes it an offence intentionally to arrange or facilitate a child sex offence, whether committed by the defendant or another person. The offence is complete even if the intended abuse never takes place. Crucially, it applies even where the defendant was communicating with an adult posing as a child — including an undercover police officer or a vigilante group member. Evidence obtained by vigilante groups requires scrutiny on admissibility and reliability grounds.
Peer-on-Peer Cases and Position of Trust Offences
Where the defendant is under 18, offences are prosecuted under section 13, which provides a reduced maximum penalty. Prosecution guidelines require consideration of the relative maturity of the parties, any imbalance of power, and whether exploitation was involved. These cases are frequently suitable for out-of-court disposal. For position of trust offences under sections 16 to 24, an adult who holds a position of trust — as a teacher, coach, or carer — commits a criminal offence by engaging in sexual activity with a person under 18 in their care, even where the activity would otherwise be lawful.
What to Do if You Are Under Investigation
If you have been arrested, had devices seized, or are asked to attend a police interview in connection with any sexual offence involving a child, seek specialist legal advice immediately. Do not speak to investigators without a solicitor present. The pre-charge stage is the most important period for presenting material that may affect whether a prosecution is brought.
