Travel and holiday rules will change again on Sunday morning, meaning a different set of procedures for people arriving back in England.
From Friday people have been allowed to arrive in the UK without having taken a Covid test to prove that they are negative.
And from 4am on Sunday people will no longer need to take a PCR test on the second day after they arrive in the UK to prove they still don't have Covid.
Instead people will be able to take a much cheaper home lateral flow test.
People arriving in England will also no longer need to isolate between the time of their arrival and getting the test result.
Setting out the rules, the UK Government website reads: "If you qualify as fully vaccinated for travel to England, and you will arrive in England after 4am, Sunday 9 January, you can choose to take a lateral flow test instead of a PCR test after you arrive in England."
Anyone who gets a positive lateral flow test will then have to isolate and take a PCR test.
The rules don't apply to any arrivals who aren't vaccinated, who still have to quarantine.
And the rules only apply when you are coming into the UK - not when you are arriving in other countires.
Tourist destinations such as Spain and Cyprus insist you take a Covid test when you arrive while other countries, including France, have banned any travel from the UK.
