If you are arriving from within the Common Travel Area (CTA), that is Ireland, Isle of Man and Channel Islands and have been in the CTA for the last 14 days before entering the UK, you will not need to complete the Public Health passenger locator form or self-isolate.

If you are arriving from the CTA and entered the CTA within the last 14 days, you will need to complete the Public Health passenger locator form.

You will need to self-isolate if you have visited or transited through a country that is not on the travel corridors list during the 14 days before your arrival. You will need to self-isolate until 14 days have passed since you left that country.

You can show details of recent travel into the CTA, such as a boarding pass or itinerary, to help confirm whether you entered the CTA in the last 14 days and how long it has been since you visited or transited through a country that is not on the travel corridors list.
