Arriving in the UK

Latest update: 19 July 2021


Flying to the UK? Here's what you need to prepare before your flight.

As part of the UK Government’s COVID-19 response, passengers require additional documentation for entry into the UK. Check the latest restrictions and find out which tests are required for each step of your journey.

Pre-departure negative COVID-19 test report

Regardless of where you’re flying from, you must show evidence of a negative pre-departure COVID-19 test at your departure airport, taken within 72 hours before the scheduled time of your flight. 

Upon check-in, you will have to show your official test result report which must be in English. The name on your test report must be identical to your travel document e.g. if your name shows “CHAN TAI MAN CHRIS on your passport, all parts of “CHAN TAI MAN CHRIS” must also be printed on your test report.

Pre-booked COVID-19 test(s) to be taken after arrival

The UK Government has introduced a traffic light system with countries on green, amber or red lists. 

If you have only been in a green country in the past 10 days (e.g. Hong Kong, Taiwan, Australia or New Zealand), before arriving in the UK you will need to book and pre-pay for one test. This needs to be taken on or before day 2 after your arrival (arrival date is day 0). 

You must book and pre-pay for two tests, to take place on day 2 and day 8 if you are arriving from an amber or red country.  If you are fully vaccinated under the UK vaccination programme (and it has been at least two weeks since your final vaccination), or are aged 5-18, you will only be required to pay for and take the day 2 test.

You must follow these rules even if you have been fully vaccinated. If you are connecting to another international flight in London, you do not need to complete the arrival tests if you remain airside (you do not pass through UK border), however you will still need to have a pre-departure COVID-19 test and complete the following Passenger Locator Form.

There are no testing requirements for children aged 4 and under.

A Passenger Locator Form must be submitted online prior to your arrival in the UK, at any time in the 48 hours before you arrive. As there are potential fines for not completing this form accurately, we’ve put together the following information to help you prepare for check-in before your flight to London:

  • Complete one form per person. If someone under 18 years old is travelling with you and staying at the same UK address as you, they can be included on your form.
  • As the form requires your seat number, please check in online before coming to the airport so you can choose your preferred seat ahead of time. We will provide you with your boarding pass at the airport after checking your travel documents.
  • If you are staying in the UK, you are required to book and pre-pay for two COVID-19 tests as above. The booking reference for these tests must also be included in the Passenger Locator Form. A valid booking reference number will be in the form of five letters followed by a series of alphanumeric characters (e.g. ABCDE1122XX33). 

Quarantining after arrival from an amber or red list country

  • Amber

You’ll need to quarantine at home or in the place you’re staying for 10 days, unless you have been fully vaccinated under the UK vaccination programme (and it has been at least two weeks since your final vaccination), or are under 18.

  • Red

You are required to stay in a managed quarantine hotel for 10 days. Find out more about booking and staying in a quarantine hotel.
