If you do not meet the requirements to classify as a 'blue channel' passenger, then the categorisation of a country or region at the time you register your journey will determine your self-isolation and testing requirements. Details of the country/region classifications and the requirements for each can be found here.
Therefore, if a country/region you have visited moves from Category 3 to 4 before you register your journey, you will be subject to a mandatory minimum 14-day-self-isolation period.
If a country/region you have visited moves from Category 3 to Category 4 after you have registered your journey, you will not be subject to a mandatory minimum 14-day self-isolation period.
Similarly, if a country/region moves from Category 4 to Category 3 after you have registered your journey, you will still have a mandatory minimum 14-day self-isolation period. The same applies to a change from Category 2 to Category 3 or Category 3 to Category 2.
Please be aware that countries/regions included in Categories 1, 2, 3 and 4 are subject to change at short notice.
For non-'blue channel' passengers, the test on arrival (Day 1) will be a supervised ‘self-swab’ undertaken at the airport or harbour. To register your self-swab you can use a personal device with a camera to scan the barcode on the tube, or use a kiosk at either the airport or harbour. Please note that we anticipate the process taking longer if customers choose to use the kiosks.
