Confidential STI testing IN LONDON
Most people who book this are anxious about two things: the result, and being seen. Both are worth addressing plainly.
- On being seen. Burnett Road, Streetly is a general medical location, not a signed sexual health service. Nobody in the waiting area knows why anyone else is there.
- On confidentiality. Your records stay with us. Nothing is passed to your NHS GP unless you specifically ask us to, and you do not need to be registered with a local practice to be seen.
- On the result. If something is positive, we treat it here where we can, and explain what it means and who else needs to know. You will not be handed a result and left to work out the next step.
SAME DAY STI TESTING IN LONDON
When to test after a risk
This matters more than how soon you can be seen. Testing too early gives a result that reassures you wrongly. The Early Detection panel is for less than 10 days since the exposure, the Complete panel for after 10 days, and HIV testing is reliable from 28 days. If you come in too early we will tell you, and tell you when to come back.
Getting your results
What we test for IN LONDON
- STI Early Detection, £295. For less than 10 days since exposure. Chlamydia trachomatis, gonorrhoea, syphilis, herpes simplex I and II, mycoplasma hominis and genitalium, ureaplasma urealyticum, bacterial vaginosis and haemophilus ducreyi.
- STI Complete, £495. For after 10 days. HIV, hepatitis B and C, chlamydia, gonorrhoea, syphilis, herpes simplex I and II, ureaplasma and mycoplasma, trichomonas and gardnerella.
- HIV test, £195. Reliable from 28 days after exposure. HIV antibody and p24 antigen.
Individual tests are also available if you only need one thing checked. Free NHS testing exists too, and if cost matters more than speed it is worth looking up your local NHS sexual health service before booking here.
What happens after your results IN LONDON
Results come back the next day and someone talks you through them.
- If everything is negative, we will tell you whether the timing of your test means it can be relied on, or whether one marker needs repeating later.
- If something is positive, most infections we test for are straightforward to treat and we treat them here. Chlamydia is a short antibiotic course. Gonorrhoea needs an intramuscular injection and a test of cure afterwards. Syphilis and HIV need specialist care and we arrange the referral rather than leaving you to find it.
- Partner notification is part of the conversation, not an afterthought. We will help you work out who needs telling and how, including anonymously.

STI testing London FAQs
The FAQ carries only distinct, high-intent questions not already answered above.
Usually yes. Same day appointments are generally available and you can walk in during opening hours. No referral needed.
It depends on the test. The Early Detection panel from under 10 days, the Complete panel after 10 days, HIV from 28 days. Coming in too early is the commonest mistake, and if you do we will tell you when to come back rather than take your money for an unreliable result.
Yes, and no. Your records stay with us and nothing goes to your NHS GP unless you ask us to.
Yes, during opening hours.
No, and you do not need to live locally either.
We help with it, including anonymous options. It is part of the appointment rather than something left to you.
Next day for all three panels.
£195 for HIV alone, £295 for the Early Detection panel, £495 for the Complete panel.
We are at Portman Square in Marylebone, in the medical district beside Harley Street. Baker Street, Bond Street and Marble Arch stations are each a few minutes on foot. It is a general medical location rather than a signed sexual health service, so nobody in the waiting area knows why anyone else is there.
Yes, where we can, at the same location. Chlamydia and most bacterial infections are treated here. Syphilis and HIV need specialist care and we arrange that referral.
Yes. NHS sexual health services offer free testing and you can find your nearest through the NHS website. If cost matters more to you than speed, that is the better route and we would rather say so.
Yes, and most people we see have none. Chlamydia in particular is usually symptomless, which is exactly why testing after a risk matters.
