Private STI Testing in South Kensington, London

Our private sexual health clinic in South Kensington provides confidential STI testing with gold-standard PCR diagnostics. Whether you're experiencing symptoms, have had a potential exposure, or simply want peace of mind with a routine sexual health check, we offer immediate access without the wait times of NHS services.

Walk-in appointments and pre-booked sessions are available Monday to Saturday, ensuring you have immediate access to advanced diagnostics when you need them most. We operate a strictly professional medical environment with no registration required and complete discretion guaranteed.

Comprehensive STI Screening Services

We test for all common sexually transmitted infections including Chlamydia, Gonorrhoea, HIV, Syphilis, Herpes (HSV-1 & HSV-2), Hepatitis B & C, Mycoplasma, Ureaplasma, and Trichomoniasis. Our comprehensive STI screens provide complete peace of mind with a single visit.

Unlike home testing kits, our clinic provides professional sample collection by trained clinicians, ensuring accurate results. All testing is performed at UKAS-accredited laboratories using the latest molecular PCR technology for maximum sensitivity and specificity.

Why Choose Private STI Testing?

Many patients prefer private sexual health services for several important reasons. Our clinic offers same-day appointments without the weeks-long waits common at NHS GUM clinics. Results are delivered securely from 1-2 days, compared to 7-14 days through the NHS.

Privacy is paramount in sexual health. We never contact your GP without explicit consent, accept cash payments to avoid bank statement traces, and maintain complete discretion at every stage. Your name is never called in waiting areas, and all consultations take place in private rooms.

Expert Clinical Care

Our clinic is CQC regulated and staffed by GMC-registered doctors and experienced sexual health nurses. If your results require treatment, our clinicians can prescribe appropriate antibiotics or antiviral medications, ensuring you receive complete care without additional appointments elsewhere.

We understand that visiting a sexual health clinic can feel daunting. Our team is non-judgmental, professional, and experienced in putting patients at ease. Whether this is your first STI test or a routine check-up, you'll receive the same high standard of compassionate care.

Frequently Asked Questions

How quickly can I get STI test results?
Most STI test results are available within 1-2 days (blood tests: 1 day, PCR tests: 2 days). Our PCR-based testing provides highly accurate results with rapid turnaround. Urgent same-day results may be available for certain tests - please ask at reception.
Is STI testing at your clinic confidential?
Yes, all testing is 100% confidential. We do not notify your GP or share results with anyone without your explicit consent. We accept cash payments so there is no trace on bank statements, and we do not call out names in waiting areas.
Do I need to book an appointment or can I walk in?
Both options are available. You can book online for a guaranteed appointment time, or simply walk in during our opening hours (Mon-Sat). No registration or GP referral is required.

When should I get tested after exposure?
Window periods vary by infection. Most bacterial STIs (Chlamydia, Gonorrhoea) can be detected within 2 weeks. HIV testing is most accurate after 4 weeks with 4th generation tests. Our clinicians can advise on optimal testing times based on your situation. Read more about STI testing windows.
