Covid19 Test to Release

Screen4 (Yorkshire) Ltd are proud to be listed on the Governments list of “Approved providers” offering International Travelers access to the Test to Release Covid19 Services. We have partnered with Oncologica Ltd, a government approved laboratory to provide a reliable and smooth process for your testing needs. 

If you are returning to England from a country not on the government’s travel corridor list, you will need to self-isolate and not leave your home for 10 days – unless you take a Covid19 and receive a negative result. This is known as Test to Release. The earliest you can take the test is 5 full days after you left a country not on the travel corridor list. You will still need to self-isolate until you receive a negative result.

The scheme is voluntary and applies to those self-isolating in England only.

How will the Test to Release system work?

24 hours before your trip comes to an end: You will need to have a look on the government travel corridor list and check to see if the country that you are returning is on the the governments travel corridor list or not. If it is not you will need to book a Test to Release Covid19 PCR clinician performed test.

  • Day One: You arrive back in England from a quarantine country, you need to go straight to your self isolation destination and begin your isolation period in line with the UK governments instructions.
  • Day Five: You can now physically attend your booked clinician appointment, your sample will be couriered directly to the lab as part of the service. 
  • Day Seven – Eight: You will receive your results via email, if this is Negative you are able to end your self-isolation period. If this results is anything other than Negative you will need to contact us immediately to discuss.

International arrivals who arrive in England after 9pm on 23rd December who have been in or transited through South Africa in the previous 10 days will not be able to shorten their self-isolation period through Test to Release. International arrivals who arrived in England before 9pm on 23rd December who have been in or transited through South Africa in the previous 10 days, including those who have not yet booked or taken a test to release, can still use the scheme
