Paying for sex in Britain: the law, scams, STIs and a next-morning action plan

If this happened only hours ago: after a possible HIV exposure, do not wait for symptoms. PEP must be started as soon as possible, ideally within 24 hours and no later than 72 hours. Contact a sexual health clinic, or A&E when clinics are closed. Call 999 or 112 if anyone is in immediate danger. After suspected spiking, memory loss or sexual assault, call NHS 111 or London’s The Havens on 020 3299 6900, 24/7. Care is available whether or not you want to report to police.

The central myth: “prostitution is legal in Britain”

There is no single answer for the whole UK. Even where a private exchange between consenting adults is not itself an offence, the location, method of approach, third-party involvement, coercion or age may make the conduct criminal. Payment never turns every situation into a lawful one.

• England and Wales. A private exchange between consenting adults is not automatically prohibited, but soliciting another person in a street or public place to obtain paid sexual services is an offence, including from a vehicle. Brothel-keeping, controlling prostitution for gain, trafficking and other exploitation are criminal offences. Paying for the sexual services of someone subjected by a third party to force, threats, coercion or deception is a separate strict-liability offence: CPS guidance says that not knowing about the exploitation is not a defence.
• Scotland. As at 10 October 2026, private selling and buying are not automatically illegal. Public soliciting or loitering to buy or sell sex, brothel-keeping, procuring, exploitation and trafficking are illegal. An independent commission is considering possible future criminalisation of purchase, but a reform proposal is not current law.
• Northern Ireland. The position is different: paying or promising payment for a person’s sexual services is a criminal offence under section 15 of the 2015 Act. Meeting online or indoors does not make the purchase lawful.

Age and consent. Never proceed where age is uncertain; commercial sexual exploitation of a child is a grave offence. Payment is not consent to everything. Consent applies to each act, can be conditional on condom use and can be withdrawn at any moment. Someone asleep, unconscious, or so intoxicated by alcohol or drugs that they cannot choose lacks capacity to consent.

The specific London tourist warning

The Metropolitan Police tells visitors to be wary of Soho venues advertising sex shows. Customers may face very high charges even for non-alcoholic drinks, as well as charges for a hostess’s company and drinks. This is an official warning, not an allegation that every venue in the area is fraudulent.

• Ask for the full price and every fee before ordering. Do not accept “we will calculate it later”.
• Never surrender a passport, bank card or phone as security, and never disclose a PIN. A genuine police officer will not demand cash or your PIN.
• Do not follow links sent for “age verification” or transfer a large deposit to a stranger. A profile screenshot does not prove identity.
• Leave valuables in the hotel safe, tell a trusted person where you are and when you expect to return, and do not let a stranger choose the cashpoint.
• Use licensed transport. Only a black cab may be hailed in a London street; a minicab must be pre-booked. An unbooked minicab is illegal and uninsured.
• Do not make photographs or recordings without express consent. Do not threaten to publish messages or images.

Warning signs of exploitation

Pause and leave if another person answers every question, takes the money, controls the adult’s phone or documents; if the person appears frightened, cannot leave freely, does not know the address, or lives where clients are received; or if boundaries suddenly change and a minder appears. No single sign proves trafficking, but doubt is enough reason not to pay.

Do not confront a suspected controller. Call 999 if anyone is in immediate danger. Otherwise contact police on 101 or the Modern Slavery Helpline on 08000 121 700; concerns can be reported anonymously.

Reducing health risk

• Use a new condom from the start of every vaginal or anal act and barrier protection for oral contact. Use water- or silicone-based lubricant with latex; oils can damage latex.
• Condoms greatly reduce HIV and many STI risks but cannot fully prevent infections spread by skin contact, including herpes and HPV.
• Do not wear two external condoms at once. Friction can increase breakage. Use a new condom when changing the type of sexual contact.
• If you are too intoxicated to check the condom, price, boundaries and journey home, you are too intoxicated to make a safe decision. Alcohol does not remove the legal duty to establish consent.
• For repeated risk, ask an NHS clinic about free HIV PrEP and hepatitis A/B or HPV vaccination. PrEP does not prevent other STIs or pregnancy.

What may become apparent the next morning

No symptoms does not mean no infection. Discharge, pain when urinating, ulcers, blisters, warts, rash, itching or unusual bleeding can occur, but chlamydia, gonorrhoea, syphilis and HIV may be silent. NHS guidance says some STIs can take up to seven weeks to show on a test. That is not a reason to wait seven weeks before seeking advice: a clinic can assess risk now, take baseline samples and tell you when to repeat them.

1. Within 72 hours: urgently ask about PEP after possible HIV exposure. It is a 28-day course offered after clinical risk assessment and works best when started within 24 hours.
2. Within 3–5 days: emergency contraception is time-limited. Levonorgestrel must be taken within 72 hours, ulipristal within 120 hours; a copper IUD can be fitted within 120 hours and is the most effective option.
3. Today: seek immediate care for pain, discharge, ulcers, rash, injury, suspected spiking or assault. Do not self-treat with leftover antibiotics.
4. Until assessed: do not have sex without a condom, including oral sex. If an infection is confirmed, the clinic can help notify partners without naming you.

What testing and treatment cost

Bacterial infections such as chlamydia, gonorrhoea and syphilis are generally treated with antibiotics, but the clinic must choose the regimen; resistant gonorrhoea makes self-medication particularly unsafe. Antivirals can manage herpes but do not remove the virus. HIV is now effectively controlled with treatment. Delaying care does not reduce the risk — it only loses time.

Where to go in London and across the UK

56 Dean Street, Soho: 56 Dean Street, London W1D 6AQ; 020 3315 5656. The official NHS listing includes STI testing and treatment, PEP, PrEP, emergency contraception and help after sexual assault. A possible HIV exposure within 72 hours is treated as urgent. Opening arrangements change, so check before travelling.

The Havens, London: urgent 24-hour number 020 3299 6900. Centres are near King’s College Hospital in Camberwell (SE5 9RS), St Charles Centre in Paddington (W10 6DZ), and the Royal London Hospital in Whitechapel (E1 5DG). They accept self-referrals after rape or sexual assault and can provide healthcare and preserve evidence without requiring a police report.

In England use the NHS clinic finder. Scotland provides free services through NHS Inform; Wales through NHS 111 Wales; Northern Ireland through your HSC Trust GUM service. Call 111 for urgent non-emergency medical advice and 999 or 112 where life or safety is at immediate risk.

Memory loss, suspected spiking or assault

Sudden confusion, much stronger intoxication than expected, loss of balance, vomiting, visual disturbance, unconsciousness or memory gaps can indicate added alcohol or drugs. The Met stresses that spiking is illegal even when no theft or assault follows.

Move to safety and ask a trusted person or venue staff for help. Call 999 for severe symptoms or immediate danger and 111 for urgent medical advice. Report quickly because some substances have a short forensic window. If possible, do not wash clothes or discard potential evidence, but seek help even if you have already washed or changed. Whether to report to police is your choice; healthcare does not depend on it.

A short decision plan

If you want intimacy but feel afraid, the safest option is not to buy an unknown service while intoxicated. Return to your accommodation by licensed transport and decide when sober. If a meeting happens: clear consent, no doubt about adulthood, agreed acts and total price, a condom from start to finish, no surrender of documents, and immediate departure at any sign of fear or control.

The next morning, choose action over shame: note the time and type of contact, check your card and cash withdrawals, freeze the card after an unexplained transaction, preserve messages, do not pay blackmail, assess the 72-hour PEP window and the 3–5-day emergency-contraception window, and contact a sexual health clinic.
