Which tests do I need?

Last updated: 02/11/21

The tests you need to take after you arrive in the UK depend on:

  • whether you qualify as fully vaccinated for travel to the UK
  • where you have been in the 10 days before you arrive

You qualify as fully vaccinated or you are under 18 if:

  • You can prove you have received a full dose of an approved vaccine at least 14 days before arriving.
  • Or, you’re aged 18 or under and resident in the UK or a country or territory that has approved proof of vaccination.
  • Or, you’re taking part in an approved vaccine trial.
  • You have not been in a red list country in 10 days before you arrive.

If you qualify as fully vaccinated and are arriving in ENGLAND you can book a Day 2 Lateral Flow Test

You do not qualify as fully vaccinated for travel to the UK if:

  • You are over 18 and you have not received a full dose of an approved vaccine at least 14 days before arriving.
  • You have not been in a red list country in 10 days before you arrive.

You will be required to quarantine for 10 days upon arriving in the UK and will be required to take Day 2 and Day 8 PCR Tests. You have the option of taking a Day 5 Test to Release PCR test which if negative will enable earlier release from quarantine.
