The UK's new quarantine rules for incoming travellers came into force on 8 June, with arrivals into the country now having to undergo a mandatory 14-day period of self-isolation.
The measure is being introduced to prevent new infections from imported cases.
Travellers must fill in a form with their contact information and the address of their accommodation, which health officials will use to perform spot checks to ensure compliance.
The measures apply not just to those arriving by air travel, but by other means of transport such as ferry.
But there are a few exception to the rules.
Here's everything you need to know:
Who is exempt from the new rules?
You do not need to complete the form or self-isolate if you’re travelling from one of the following places, and you were there for 14 days or more:
- the Channel Islands
- the Isle of Man
If you spent less than 14 days in any of the above place, you will still need to complete the form and self-isolate for 14 days.
There are other exceptions to the rules too:
- Members of diplomatic missions and consular posts in the UK
- Officers, servants or representatives of international organisations
- Representatives at an international or UK conference granted privileges and immunities
If you fall into the above categories, you do not need to complete a Public Health passenger locator form.
But if family members or other dependents travel with you, they will still need to self-isolate for 14 days after they arrive.

What does the Scottish Government say?
In Scotland, the Scottish Government add that people “travelling to maintain essential supply chains, critical national infrastructure or to contribute to crisis response or other essential government work,” are exempt.
Registered health or care professionals travelling to the UK to provide essential healthcare, including where this is not related to coronavirus - will need to self-isolate for 14 days if they are staying in Scotland.
Likewise, if you live in the UK but work in another country and travel between the UK and country of work at least once a week; and/or you live outside the UK but work in the UK and travel between your country of residence and the UK at least once a week - you will need to self-isolate for 14 days.

How does it all work?
If you arrive in the UK from 8 June onwards, you must complete a 'Public Health passenger locator form' before you travel.
You cannot submit the form until 48 hours before you’re due to arrive in the UK.
You’ll need to show your completed form when you arrive at the UK border, either by printing a copy, or showing it on your phone.
Once in the UK, you'll need to go straight to the place you’re staying, only using public transport if you have no other option.
If you do have to use public transport, you will have wear something that covers your nose and mouth, and stay 2 metres apart from other people.
Once you have arrived at your declared address, you must self-isolate there for 14 days, where you can have food and other necessities delivered.
You should not have visitors, including friends and family, unless they are providing essential care.
The only friends and family who you can have contact with are those who travelled with you or people who you are staying with.
You cannot go out to work or school or visit public areas. You should not go shopping. If you require help buying groceries, other shopping or picking up medication, you should ask friends or relatives or order a delivery.
You must only exercise within your home or garden. You cannot leave your home to walk your dog.
