Significant changes to the UK's travel requirements have been announced by the government on 5 January 2022:
From 04:00 GMT on Friday 7 January, people who are fully vaccinated and those aged under-18 will no longer need to take a test two days before travelling to England from countries outside the UK and the Common Travel Area. On arrival, they will have to take a PCR test but they will no longer have to self-isolate while awaiting the result
From 04:00 GMT on Sunday 9 January they will only have to take a lateral flow test instead of a PCR test on day two. But this test must be bought from a private test provider - free NHS tests are not allowed
Unvaccinated passengers will need to continue to take a pre-departure test, PCR tests on day two and day eight, and self-isolate for 10 days
