The government has taken Portugal, one of the UK’s most popular tourist destinations, off the green travel list.

The government’s traffic light travel system puts countries into green, amber and red categories.

What does this mean for travellers leaving and returning to the UK?

Green list

Green list countries require a negative coronavirus test result before travel and a further test upon return. But, you do not need to quarantine when you get back to the UK unless you have test positive for the coronavirus.

You will have to pay for both PCR tests from one of the government’s approved providers. Lateral flow tests are not approved for travel testing.

Amber list

The government advises against travel to countries on the amber list.

Most countries are on the amber list, including popular tourist destinations like France and Greece.

In order to travel to an amber list country, you must have proof of a negative coronavirus test before departure.

You must also book a test on day two and day eight after returning.

Those from amber list countries must also complete 10 days of quarantine.

However, you can end the quarantine early if you use the test-to-release scheme.

Red list

Red list countries are considered the highest risk.

Dozens of countries including Turkey, India and Brazil are on the UK’s red list.

If you have been to a red list country in the last 10 days, you can only enter the UK if you are a British or Irish national or UK resident.

Those returning from a red list country must complete a passenger locator form and self-isolate in a government-approved quarantine hotel for 10 days.

You must also pay for the hotel, which costs £1,750 per adult.

After criticism over arrivals from differently listed countries mixing, a new facility has opened at Heathrow Airport for returning red list passengers.
