About Instant Covid Tests London

Our Covid-19 Testing Mission


Instant Covid Tests London is a privately-run Covid screening service.

Our Covid screening centre is located in central London, just a few minutes’ walk from Liverpool Street, Moorgate and Barbican stations in EC1. If you have an organisation with a large testing requirement with can provide an on-site offering.  We offer quick and affordable, non-invasive Covid testing for asymptomatic individuals and business workforces, with accurate positive/negative results in just 20 seconds. The Virolens™ testing we provide has no impact on the availability of testing to NHS workers or those being tested through government schemes. We are not funded by the government and all costs associated with our Covid testing service are fairly reflected in our fees.

We believe that mass testing for everyone – not just those with Covid symptoms – is key to preventing the spread of the virus. This is why we’ve designed a testing process that’s as quick and easy as possible, so that both individuals and businesses in London have a regular Covid screening service they can trust. We offer safe and convenient regular testing so that people can get back to work and normality with the assurance they need. While our Virolens™ tests are partially self-administered – you take your own mouth swab sample and put it into a cartridge – our in-house team of experts are then on hand to operate the testing devices. Full post-test support is available for anyone who tests positive, including guidance on what to do next.

Above all, our mission at Instant Covid Tests London is to provide the immediate clarity we all need to do our part in preventing the spread of Covid-19, whether that’s ensuring we are clear of the virus or self-isolating to protect others. Our quick, simple and medically-supported instant Covid tests are there to help you live and work with confidence and peace of mind.
