Underage Sex: How to Protect Your Children

What the law says about underage sex

The age of consent in England, Scotland, Wales and Northern Ireland is 16. Sexual activity with anyone below this age is a criminal offence, regardless of whether both people are under the age of consent.

Sexual activity is defined broadly under UK law. It includes penetrative sex, oral sex, and sexual touching or masturbation. The law applies equally to heterosexual and homosexual activity.

The law also makes specific provisions for positions of trust. Adults who work with young people, such as teachers, coaches or care workers, commit an offence if they engage in sexual activity with anyone under 18 in their care. This applies even though 16 and 17 year olds are above the general age of consent.

Prosecutors and police consider the circumstances carefully before deciding whether to take action. Two 15 year olds in a relationship will usually be treated very differently from an adult who targets a child. But the activity remains illegal, and law enforcement takes all cases seriously.

How cases are handled in practice

The Crown Prosecution Service has guidance on approaching cases involving young people. Factors that influence a decision include the ages of those involved, whether there was any coercion or manipulation, and the nature of the relationship.

Where both parties are of similar age and the activity was genuinely consensual, a prosecution may not be considered in the public interest. This does not make the activity legal, and formal criminal proceedings can still follow.

Where there is a significant age gap, or where any form of pressure or exploitation is involved, the situation is treated far more seriously. Sentences for sexual offences against children can include lengthy prison terms and placement on the sex offenders register.

Parents should understand that even if no prosecution takes place, a referral to social services or other agencies may still occur if professionals become aware of underage sexual activity.

Your situation may be slightly different. ask a question below ↓ and our editorial team will reply with our advice.

Talking to your children

This is difficult territory for most families. Some parents feel that frank conversation helps keep children safer. Others prefer to emphasise that sexual activity should wait until the legal age or later. This article does not advocate for any particular approach.

What most professionals agree on is that children benefit from understanding the law and the potential consequences. They should know that sexual images of under 18s are illegal to take, share or possess, even if they created the images themselves. This is covered by laws on indecent images of children.

The concept of Gillick competence is also relevant here. This legal principle recognises that some young people under 16 may be mature enough to consent to medical treatment, including contraception, without parental involvement. It does not change the age of consent for sexual activity, but it does affect how health professionals can advise young people.

Organisations such as the NSPCC and Childline offer resources for parents and young people on these topics. Schools also cover relationships and sex education as part of the curriculum, though the depth and approach varies.

Where to find further information

For legal detail on sexual offences and the age of consent, GOV.UK and the Crown Prosecution Service website provide official guidance. The Sexual Offences Act 2003 sets out the framework for England and Wales, with separate but similar legislation in Scotland and Northern Ireland. Readers should verify current details as legislation can change.

If you are concerned about a child's safety or believe a child may be at risk of exploitation, you can contact:

  • The NSPCC helpline on 0808 800 5000
  • Childline on 0800 1111 for children and young people
  • Your local police or social services

These conversations are rarely easy. Knowing the legal framework can help, but talking about sex with your children will probably still feel awkward. That is normal.

@Mrs C Tan You've raised a serious concern, and it deserves a straight answer rather than a PR line. Could you point to the specific policy wording you're referring to? I've had a look through our current guidance and can't find anything permitting adult males to supervise girls changing, so I'd like to check whether this is our page or something you've seen elsewhere being attributed to us. Single sex spaces are protected under the Equality Act 2010, and we're bound by that same law.
Mrs C Tan 15/09/2026 at 4:00 pm
WHY ARE YOU ALLOWING BIOLOGICAL MEN IN GIRLS CHANGING ROOMS?.
I understand you will be allowing biological men to watch over young girls changing in changing rooms. That your revised policies now allow this where they did not before. I will no longer fund you in any way. You will be contributing to the very cause you claim to save.
I request that you revoke your new policy and change it back, in order to safe guard children. We will be watching you very, very closely. It is appalling that you have made this very, very dangerous change. You only need to review the statistics of mens abuse to women and children, which you clearly understand. A man is biological and You must comply with the law! You are flouting the law, in order to appease a few biological men, putting children at risk.

I’m 12 and I have a crush on an 11 Yr old girl. She is very hot. I’m in California is there any legal way to say “I wanna fkkk you”?
Mr plod. 06/12/2020 at 12:20 pm
I totally agree with the comment about, borderline paedophilia. What are you people hoping to achieve. Some of the stories...are fairy tales at best. This is a serious problem and all people are doing is titillating their sick fantasies. Shame on all of you.

I'm a 11 year old girl and I'm dating a fourteen year old girlfriend dad knows but not my mom. When I'm around my girlfriend I feel very weird it feels like I want to do more when were alone but then my mind starts to flash some things that get me hyped.it so hard for me to control myself

Me and my boyfriend are 15 and we where going to do stuff while my mum was in work but I didn't know she would be back early and as soon as me and my boyfriend got naked my mum walked in my room and know I don't know how to feel as she told his parents which is making me not want to go his house
Eli 17/10/2020 at 6:31 pm
When I was young, around 11, I was a bad kid. I would sneak out of my house and visit someone who was 3 years older than me. We are together now, but anyways, I would visit her, and I lied to her, saying that I was also 14. After she turned 15, I asked her if she wanted to do it. I knew she would answer "No" but I thought it would be proof that "I was her age"
Anyways, I just wanted to share my expirence with this. I knew then, and I know now that it was very wrong, and shouldn't have asked her, or even been dating her.
(Don't think i'm a boy. I am bi girl lean and a girl) She is now 25, and I'm 21. She also knows that I lied to her, but after a while she understood why

Childline is important also. If you are a child and need support, they are there for you. You deserve care and support x
Jaz 09/08/2020 at 6:00 am
The places mentioned before are places to get support in feelings and also home to information on the websites. Sending more care your way x
jaz 09/08/2020 at 5:05 am
I don't seem to be able to forward the links, so wanted to mention that there is information on these websites for help and support:

- Childline
- Time to Change has a list of call lines if anyone wants someone to speak to
- NHS a list of mental health support charities to talk to/ email/ text
- NHS has information regards to abuse also

Sending care x

I am litterally tripping at the majority of the comments on this site! I thought the first couple was a sick joke, but as I scrolled, all of these comments are sick, twisted, child molesting crap! What is wrong with you people? Your going to hell in a hand bag! I'd hate to be any of you when it comes time to stand before God!

Hi, I would and will allow my kids to sleep and date whoever they want to after they turn 12 years of age. Its their business whom they choose and what age. Why as a society have we started making laws on who people can sleep with. We need to sop all the governing of our body by our government. Our body, our life, our partners.

My 11 year old daughter is dating my 22 year old nephew but she is pregnant I don’t want him to get prosecuted so I wondered if I could change the law ? Could I sue him instead my family needs more money is that legal ?
Veronica 30/11/2019 at 12:36 pm
Okay. so my boyfriend is a drug addict and he beats both me and his son, his son is 15, and i'm 37, and hes raped me on multiple occasions. I liked it but if i reported it as rape would he get in trouble and not me? By the way my boyfriend gives his son drugs when doesn't know, so this may be the reason his hormones are acting up.
Kev 27/11/2019 at 6:52 am
My 13 year old daughter as thought about taking thing to next level with her 15 year old boyfriend. Would this be against the law if he persuaded her to sleep together or she did It off her own!??

My 15 year old daughter has just had a baby and the father is 18 years old. Will he be prosecuted? as she can't consent because of her age according to social services.

BJ 13/03/2019 at 6:46 am
My 14 yo stayed with his girlfriend st her home. Her Mom said it was fine with her. She's 11 almost 12. Mom assured me she could hear anything that went on in her home. Well now that they have broken up the girl is saying they messed around but not all the way but Mom is pushing for her to say they have. My question is they were under her Moms care and she left them alone together which I would not have approved of. What can I do to protect my 14 year old?

My sister is 15, (I am 12) and I’m really scared that she will break a law as she has already started vaping having drugs and alcohol. She has grown up in Chelsea but is the most disgusting person literally ever!!!! I wish I had a younger sister

What is the legal situation between an 11 year old & a 15 year old?
LawAndParents Editor 24/08/2018 at 12:07 pm
This will depend on the circumstances and whether the police/CPS consider it to be in the "public interest".
Sp 21/08/2018 at 8:22 pm
My girlfriend is 15 and lives in care I am 17 and we just found out she is pregnant. Will social services prosecute me when the baby is born even though she will be 16 giving birth?
Hayjay 21/08/2018 at 4:26 pm
I am 15 and my boyfriend is 16, we keep getting told by our parents that we cannot be in the same room together or we shouldn't be in the room together. As they can get in trouble for us to being in the room. My question is can we be in the room together without parents getting in trouble? We don't do anything as we know it's illegal. I have the implant just in case though. Can we or can we not sleep in a bed together at night with someone in the room?
Janny 14/06/2018 at 11:01 am
I have a daughter who will be sixteen next month who is dating a boy one year older.
I've just been in her bedroom and found used condoms. If I tell her she can't take him upstairs anymore they will probably go & do it elsewhere. I'm proud that she's grown up & responsible enough to use condoms , but they are still breaking the law arentry they?
LawAndParents Editor 01/06/2018 at 1:59 pm
We don't know all the details, so you may have to use your own judgement here. It is common for children to get into a parent's bed and vice versa especially if a child is frightened/poorly etc. It's also common for children to ask questions about their bodies and the difference between male and female bodies, but if you feel there is more to this then talk to your wife first. If you're not happy and it continues, you may need to consider getting independent advice from an organisation like the NSPCC.

My wife shares a bed regularly with our 6,year old son, ive also heard them discussing their lower bodies, is this health for the boy?
LawAndParents Editor 29/05/2018 at 10:41 am
Please read the above article - the section entitled "Children Under 16" explains the situation concisely and is probably more comprehensive than trying to abridge for you here.

My boy 14 and sleep with a 16 year old can she be done if police are involved
LawAndParents Editor 22/05/2018 at 3:08 pm
If he's reported he may be charged or investigated.

My son is 19 and slept with a 14 year old. She consented but is he still likely to get charged? Or what will happen?
Cheryl 01/05/2018 at 7:06 am
My daughter is 15 her boyfriend is 16. He was warned by myself and his dad that he wasn’t aloud to sleep with my daughter. And did then dumped her for another 15 year old she’s seriously distraught because he’s turned all her friends against her and made her out to be a slag. Where do I stand on a police prosecution. As he was warned that she’s too young.
I need to kno 14/04/2018 at 10:36 am
Is it illigal for a parent to stop there daughter dating a boy the same age
This is happening to my son at the moment and he is always upset because he can't see her
LawAndParents Editor 11/04/2018 at 3:05 pm
We can't tell you whether or not to keep the baby. If you're worried about speaking to your parents at this stage, talk to your school's welfare/pastoral care adviser; they will almost certainly have dealt with problems just like yours before and will be able to help you.
Lhannings 11/04/2018 at 10:43 am
I'm 15 (16 in January) and my boyfriends 14 (15 in september) and I think I may be pregnant. I'm not sure wether or not I want to keep the baby as it's still early days. But I'm scared that either of us will get in trouble for it. It's not an abusive relationship we argue from time to time but it's nothing major. I need advice on wether or I should keep the baby and on wether either of us would get in trouble for it. Thanks x

My 14 year old daughter turning 15 in 4months came home with a hickey from her boyfriend who has only just turns 16. Is this illegal? Is this acceptable??

Ive recently found out my precious 13 year old daughter has being courting a nearly 18 year old. He has been texting her he loves her and Ive found out she has been to his parents house in his bedroom with the parents and sister in the house. She says he hasnt touched or kissed her. Any advice what to do? Im at wits end with worry. Im not positive but Ive heard he has an ASBO conviction and on his last warning. Im so worried about the repercussions it may have on my daughter with him being in a gang. Please advise me? Thank you

My husband's ex wife has custody of their 4 kids and lives out of state, my husband found out that his ex is letting his 13 year old son live and sleep with a 15 year old girl is there anything my husband can do? What are the laws about this?
E.D 19/01/2018 at 2:27 pm
If two girls 14 nearly 15 and 15 nearly 16 engage in outercourse and have been together for 3 months would they be prosecuted??
LawAndParents Editor 10/01/2018 at 11:17 am
The age of consent is 16 so this would be legal. Some people would consider it strange as the level of maturity of a 16/17 year old is not that of a 22 year old.
Nero 07/01/2018 at 3:55 pm
What about a 16/17 year old dating someone who is 23? The law in the uk is confusing on this stuff
LawAndParents Editor 11/10/2017 at 12:24 pm
There is always a possibility, but the police will not usually prosecute if both parties are older teenagers and there is no doubt about consent.
taz 10/10/2017 at 10:43 am
If a girl at 16 17 in a month has fell pregnant to a a boy at 14 not 15 till next year in may will there be any prosecuations he already has a child but they were both underage at this time ??
LawAndParents Editor 14/08/2017 at 2:50 pm
There is a chance the male could be prosecuted for this, the details are in the above article and because we don't have the full details it's difficult for us to comment specifically on individual cases.
Hi 13/08/2017 at 12:00 pm
Whats the implications of a 24yr old male having a relationship and intercourse and bearing a child with a 14 year old even though the girls mum accepted the relationship and allowed the partner to live with them?
LawAndParents Editor 15/06/2017 at 2:42 pm
The police can still take action and prosecute for this, though often when it's consensual, they might not take it that far.
MM 13/06/2017 at 2:30 pm
I just found out that my 14 year old son who's two months away from his 15th birthday is sleeping with his 13 year old girlfriend. I'm not happy to say the least and I'm tackling this today but I need to know what are the legal implications are please advise

My 14 year old daughter is conducting a clandestine relationship with a 30 year old who is known for his liking for underage girls. He has been meeting up with her early hours of the morning and has presented her with an engagement ring, and promises holidays in australia and porsche cars... she has recently gone on the pill, and had to be treated for an STD but still denies that she has had intercourse with this specific individual, i believe she has been coached as to the law in this area. The police are saying that there is nothing they can do... but there must be something as this is such a blatant case of grooming. We are trying all we can to cut the contact between them but she is determined as ever to "be with him". Please help!!
