rating star icon LondonA colleague recommended the Medical Express Clinic in Harley Street to me, as I needed to have a PCR swab to obtain a medical certificate for travel. I found the staff at the clinic very reassuring and will be seeing them again as my private GP clinic from now on.

rating star icon LondonThis is the best clinic for Covid travel testing. My whole family received our results in the promised time after being completely left in the lurch with postal kits, meaning we missed our flight and wasted £800 booking another one. When I found this clinic I called and spoke to the reception, who did seem extremely busy but managed to fit the whole family in for an appointment the same day if we piled into the car and got down there asap. The guy I spoke to when I called made sure our appointment was booked around the flight times and allowed for a 24hr window in case anything went wrong - from the beginning I had a bit more confidence.
When we went into the practice, which is very clean and looks new, I spoke to the nurse who took my sample about my previous experience, which was enlightening to say the least. She told me that these guys also have the postal kits, but don't use them as the results take too long, even though the tests are much cheaper. SO it turns out other clinics using the postal tests are prioritising their margins over the service to their patients, and these are private medical clinics!! If we wanted a substandard service, we would've ordered the free NHS tests! Thanks to Medical Express, the only clinic it seems that takes the PCR tests seriously, prioritising the service over their margins.

Test Certificate

If you need a PCR test certificate for your travel or immigration purpose, a letter will be included with your test result on letterhead paper, signed by the doctor and with the clinic stamp. If the result is negative, then this means you are fit to fly and you can use this letter to prove your status, as needed.

We recommend that you take a copy, or keep a version of this certificate digitally, as some immigration offices will keep the copy you present them with as evidence of your status.

Most Reliable COVID-19 PCR Test in London

Simple, we're London's most reliable COVID-19 PCR testing service.

Medical Express Clinic is a fully functional medical clinic, registered with the Care Quality Commission employing GMC registered doctors.

We have been on our premises at 117a Harley Street for over 30 years and have been using our laboratory, which is within walking distance of our clinic, throughout this entire period for our routine blood and urine testing. From our experience across this timeframe, we can say with almost absolute certainty that our service offers the most reliable testing in London.

We have been delivering COVID-19 fit-to-fly testing since they have become a widespread requirement to travel. In this roughly 6 month timescale, as we have watched other testing services deteriorate, every single patient for which we have guaranteed their turnaround time has successfully boarded their flight.

As just a part of our full clinical practice, the priority at Medical Express has always been ensuring our patients can depend on the PCR testing for travel service. Please review our Google and Trustpilot pages, and compare the feedback across the last 6 months to other testing services, many of which are unregistered and unregulated.
