Chlamydia test online UK: screening, treatment and where to go
Chlamydia testing and treatment in the UK — free NHS sexual health clinics vs online services, home test kits and when you need in-person care.

Chlamydia is the most common bacterial STI in the UK. Most people have no symptoms — which is why screening matters.
Testing options
| Route | Cost | Best for |
|---|---|---|
| NHS sexual health clinic | Free | Anyone, full STI screen |
| NHS under-25 postal kit (England) | Free | Asymptomatic screening |
| Private home test kits | £20–£80 | Convenience, discreet |
If you test positive
- Antibiotic treatment is highly effective
- Tell partners — they need treatment too
- Avoid sex until treatment completes
- Retest after 3 months if under 25
Sanara’s role
We also compare clinics for thrush, herpes and genital warts. Chlamydia screening should go through NHS sexual health services or your local GUM clinic.
Red flags
Pelvic pain, fever, or testicular pain with STI risk — same-day sexual health clinic, not online delay.
