Walk-in STI testing lets you attend a sexual health clinic without a pre-booked appointment. Many NHS clinics in the UK offer walk-in access, meaning you can simply turn up during opening hours and be seen. It’s convenient for people with unpredictable schedules or those who want testing without a planning delay.
Here’s what to expect.

Where to Find Walk-In Services
| Service Type | Walk-In Available? |

How Walk-In Works
- Arrive at the clinic during opening hours
- Check in at reception
- Wait to be seen (times vary)
- Brief consultation and sample collection
- Test processing
- Results delivered later, usually by text or phone
Waiting Times
Waiting can range from no wait to a few hours, depending on:
- Day and time (lunchtimes and early evenings are busiest)
- Location
- How busy the clinic is
- Urgency of your needs
Some clinics provide estimated wait times online or by phone.
What to Bring
- Photo ID (not always required but helpful)
- A list of any medications you take
- Notes on symptoms and dates
- Patience — peak times can mean longer waits
Advantages of Walk-In
- No need to plan ahead
- Good for urgent concerns
- Useful if appointment availability is limited
- Can fit around unpredictable schedules
Limitations
- Waits can be long at busy times
- May be closed for walk-in on some days
- Less convenient if you have specific time constraints
- Not all services offer walk-in access
Booked Appointments as an Alternative
If walk-in isn’t convenient, many clinics also offer booked appointments by phone or online. This avoids waiting but requires planning. Most clinics offer both options.
Home Testing Backup
If walk-in is unavailable or inconvenient, home test kits let you collect samples at home and post them to a lab. Results arrive in 5-10 days. Free through many NHS services.
Tips for a Smooth Walk-In Visit
- Arrive early — first thing in the morning is often quieter
- Avoid lunchtimes and after-work peak hours
- Have a book or podcast ready for any wait
- Eat and drink before you go (unless you need a specific test)
- Be patient — clinicians are doing their best
