Are STI tests free in London, and why would I choose a private test?

Yes. NHS sexual-health clinics provide free and confidential STI testing, and some London boroughs also offer eligible residents free home kits. DocTap is a paid alternative when you want a specific appointment time or clinic, a clearly defined panel, or faster results. You can review DocTap’s STI testing service at https://doctap.co.uk/sti-testing and compare current test prices at https://doctap.co.uk/sti-test-prices. HCA-led tests start at £63 for HIV, £74 for chlamydia and gonorrhoea, and £128 for the four-infection HIV, syphilis, chlamydia and gonorrhoea screen. Selected tests return within four hours at five on-site labs; most standard results from other clinics are ready by the next working day. Choose GP-led testing if you have symptoms, a recent exposure or are unsure what to test for.
