If you’re deciding between a private testing centre and a home STI test, both are valid choices with different pros and cons. Private clinics offer in-person consultation and same-day treatment; home kits offer privacy and convenience. For many people, NHS sexual health clinics remain the best option of all — free, confidential and comprehensive.
Here’s how to choose.

When to Choose a Private Testing Centre
- You want same-day results and treatment
- You have specific symptoms needing examination
- You want a comprehensive consultation
- Your local NHS service is unavailable or overbooked
- You’re willing to pay for convenience
When to Choose a Home Kit
- You value maximum privacy
- You have no symptoms needing examination
- You want a routine screen without a clinic visit
- Your local NHS service offers free postal kits
- You want to test outside clinic hours
When to Choose the NHS Sexual Health Clinic
- You want free comprehensive care
- You have symptoms or concerns
- You want access to all services (PrEP, PEP, vaccines)
- You need partner notification help
- You want in-person clinical expertise
Mixed Approach
Many people combine options — using home kits for routine screening and visiting an NHS clinic when symptoms arise or treatment is needed. This gives the best of both worlds.
What Both Options Should Include
- HIV test
- Syphilis test
- Chlamydia and gonorrhoea (urine or swab)
- Hepatitis B (and C if indicated)
- Throat and rectal swabs if relevant
Check what’s included before ordering a home kit or booking a private appointment.
Privacy Considerations
- NHS sexual health records are kept separate from GP records
- Private clinics don’t share with the NHS unless you consent
- Home kits are the most discreet — everything done in your own space
- All options protect your confidentiality

Frequently Asked Questions
Is private testing more reliable?
Not necessarily. NHS and reputable home kits use the same lab techniques with similar accuracy.
Can I be treated after a home test?
If positive, you’ll typically need to attend a sexual health clinic or GP for treatment. Some services coordinate this automatically.
What if I can’t afford private testing?
NHS sexual health services are free and widely available. Cost is not a barrier to care in the UK.
