Day 2 & Day 8

All international arrivals to England must quarantine for 10 days unless they have a job that qualifies for an exemption. From 15th February 2021, all international arrivals enter a quarantine period and are required to take a test on or before day 2 (of their quarantine period), in order that we can assess which variant you may be carrying (if positive), and a test on or after day 8 (of their quarantine period).

Test-to-Release (Day 5)

The Test to Release for International Travel scheme is for people who need to self-isolate on arrival in England.

The earliest you can take the test is 5 full days after you left a place not on the travel corridor list. (View up-to-date list here). If the result is negative, you can stop self-isolating.

If you do not want to opt into the Test to Release scheme, you will need to self-isolate until 10 full days have passed since were last in a place not on the travel corridors list.

We are providing a significant volume of support to the Travel sector where we are performing testing for a large managed service organisation that support a number of the airports across the UK with their travel testing.

We also have a number of UK shipping clients, helping to ensure their crews are infection free and able to continue to trade across the globe.

An increasing proportion of our business is focused on supporting healthcare professionals and organisations, pharmacies and businesses from all sectors with our travel testing services. For more information about our travel testing services click here.
