The most recent changes to the UK’s green, amber and red travel lists were announced on September 17 and saw Turkey, Egypt, Pakistan, Maldives, Sri Lanka, Oman, Bangladesh and Kenya taken off the UK's red list. The changes will be enacted on September 22.
These will be the last batch of changes to the UK's existing traffic-light system for travel after it was announced that from October 4, the three-list system will be replaced with a single red list and an accompanying set of simpler measures.
However, travellers from many non red-list counties will still have to abide by similar rules to those established under the traffic-light system. Only passengers from non red-list countries which are on the UK's list of approved vaccine providers will be allowed to travel almost restriction-free.
UK travel: green, amber and red lists
Which countries move off the UK's red list on September 22?
Turkey, Egypt, Pakistan, Maldives, Sri Lanka, Oman, Bangladesh and Kenya have been removed from the red list and placed on to its amber list.
They will move off the red list at 4am on Wednesday, September 22.
Turkey and the Maldives are both popular tourist destinations for people from Britain and are expecting to see a boost in bookings following the announcement.
Which countries move on to the UK's green list on September 22?
No countries were moved on to the UK's green list. The eight countries taken off the UK's red list were all moved to the amber list.
Fully vaccinated travellers on the amber list who were vaccinated by a UK approved programme must take a test three days before they travel to England, complete a passenger locator form, and book and pay for a Covid test to be taken on or before day two of their arrival in England.
Those not fully vaccinated must do the same but take two tests, one on day or before day two and one on or after day eight. They must also quarantine for 10 days in their home or place in which they are staying.
Which countries move on to the UK's red list on September 22?
No countries were moved on to the red list.
Anyone arriving in the UK from a red list country is required by law to book a stay in a Managed Quarantine Facility for 10 days. Starting August 12, the cost rose from £1,750 ($2,436) to £2,285.
More than 100,000 passengers have passed through hotel quarantine in England in the five months since the system was set up.
How are the UK traffic light system changes being decided?
The precise formula used by the UK government to determine which countries go on the green list has been the subject of much speculation — and frequent bafflement.
Robert Boyle, former chief strategist at the International Consolidated Airlines Group, said the algorithm being used to assign a country to the green list demands a case rate at or below 20, test positivity of 1.5 per cent or less and a testing rate of one or more per 100,000.
