Private Sexual Health and GUM Clinic on Harley Street
Confidential Sexual Health Services
Medical Express Clinic is a private GP practice on Harley Street that provides sexual health assessment, testing, and treatment under one roof.
Walk in without an appointment or book online. We're open seven days a week. A GP examines you when symptoms are present, prescribes treatment on the day where appropriate, and can arrange follow-up with the same doctor. Our experienced specialists prioritise your comfort, privacy, and well-being.
If you're worried about a recent encounter, experiencing symptoms, or need ongoing management of a sexual health condition, we can help. Our doctors follow BASHH (British Association for Sexual Health and HIV) guidelines and can refer onward to hospital specialists when needed.
Public Health England recorded 468,342 new STI diagnoses in England in 2023 with many infections, particularly chlamydia and gonorrhoea, being asymptomatic. The only way to know for sure that you don't have these infections is to get tested.

Quick Information for Common Questions
Can I walk in without an appointment?
Yes. We offer same-day, walk-in services Monday to Friday, 9:00 AM to 6:00 PM, and weekends 10:00 AM to 2:00 PM.
How quickly will I get my results?
Blood test results are available within 24 hours, usually faster. Urine and swab tests can take up to 3 working days as we prioritise accuracy, however in practice we often see these results returning around the 24 hour mark routinely. We also offer an urgent service with 6 hour turnaround times. For all tests, we recommend attending earlier in the day for the fastest turnaround times.
Is my visit completely confidential?
Yes. Your visit and results are completely confidential. We never share information with the NHS or anyone else without your explicit consent. You may use a pseudonym and pay with cash if preferred.
Do I need to see a doctor first?
No, you can visit us directly without a doctor's appointment if this is your preference.
Can I see a doctor if I want?
Absolutely, we offer packages that include a Consultation, Examination, Testing, and Treatment if you'd like to see a doctor. We highly recommend that patients with symptoms see our private GP for assessment.
How much does STI testing cost?
Individual tests range from £68-£270. Comprehensive screening packages range from £250-£665 and include Consultation, Examination, Testing, Treatment, and Follow-up care.
Anonymous and Confidential STD Testing
Your visit is never recorded on NHS systems. We do not notify your GP or share results with any third party. You can register under a pseudonym, pay by cash or card (the billing description is discreet), and receive results by your preferred secure method. No one in the waiting room will know the reason for your visit — we run a general practice alongside sexual health services.
Comprehensive sexual health under GP care
A GP-led assessment covers more than sending samples to a lab. We provide complete sexual health care including:
Face-to-face GP consultations with experienced sexual health physicians
Physical examination when clinically indicated or requested
Laboratory testing using advanced diagnostic techniques
Immediate treatment where appropriate
Follow-up care to ensure complete resolution
Conditions We Test and Treat
Common Bacterial STIs
Chlamydia
The most common STI in the UK, often present without obvious symptoms. Easily treated with antibiotics when detected early.
Gonorrhoea
A bacterial infection that can affect the genitals, rectum, and throat. Symptoms include discharge and pain upon urination. Treated effectively with antibiotics.
Mycoplasma Genitalium
An increasingly common infection that may cause urethritis. Requires specific antibiotic treatment.
Ureaplasma
A bacterium that may cause urethral inflammation and, in some cases, pregnancy complications if left untreated.
Syphilis
A bacterial infection with distinct stages. Early detection ensures complete cure with appropriate antibiotics, typically an intramuscular injection or a combination of antibiotics.
Viral STIs
HIV
We offer testing from 10 days post-exposure (4th generation antigen/antibody test). Early detection allows for effective management.
Herpes (HSV-1 & HSV-2)
Both blood tests and swab tests available. Symptoms include rashes and sores. Treatment manages symptoms and reduces transmission risk.
Hepatitis B & C
Blood-borne viral infections affecting the liver. Vaccination available for Hepatitis B prevention.
HPV (Human Papillomavirus)
High-risk strain testing available. Symptoms include genital warts and can lead to cancers if left untreated. HPV vaccination recommended for prevention. Treatment available in-clinic via surgical removal of lesions.
Other Genital Infections
Bacterial Vaginosis
A bacterial imbalance that can cause symptoms including odour and discomfort. Not technically a sexually transmitted infection but can be sexually associated.
Trichomonas
A parasitic infection causing discharge and discomfort. Treated effectively with specific antibiotics.
Candida (Thrush)
Fungal infection included in female screening packages. Symptoms include unusual discharge, itchiness and discomfort. Treatment available when detected.
Privacy Guaranteed
We understand the importance of discretion. Every consultation is completely confidential. You can use a pseudonym for your visit and we accept cash payments. Your results are never shared with anyone other than yourself and other service users won't know the reason for your visit.

Clinical Guidance: Most bacterial STIs are detected within 1-2 weeks of exposure. HIV testing is most accurate after 28 days, though our 4th generation tests can provide early detection from 10 days post-exposure.
If you are experiencing symptoms, we strongly recommend our Gold or Platinum packages for the most comprehensive evaluation and immediate treatment initiation.
“The most common reason people delay getting tested is anxiety about the process itself, not the result. In practice, most STI tests involve a simple blood draw or urine sample, and the majority of results come back negative. For those that don't, nearly all bacterial STIs are curable with a short course of antibiotics. Early testing means early treatment, and it means you stop unknowingly passing infections on.
