Twickenham House

Twickenham House, based at West Middlesex University Hospital, is our acute sexual health service. Being based at the hospital, we can do a range of tests not available at our other clinics. This means if you have symptoms or signs of a sexually transmitted infection (STI), this is the best clinic to attend as we have doctors available at every walk-in session and, with most infections, we can provide diagnosis and treatment on the same day.

Please note: We have a limited number of walk-in appointments available. Please arrive early to avoid disappointment. The clinic is closed on bank holidays—for emergencies please go to your nearest A&E.

Opening times

Walk-in (sit and wait)
