Like France, the UK operates a three-tier system for travel, grading countries as red, orange and green and France and the UK are currently on each other’s orange lists. In the UK, there is a possibility of two things happening to make travel from France easier – either a system to recognise fully vaccinated travellers or the moving of France to the UK’s green list. Green listArrivals into the UK from green list countries do not have to quarantine, although they still need to present a Covid test at the border and pay for a travel test pack once in the UK. The UK government says the formula for calculating which countries go on the green list is based on case numbers and vaccination rates and at present the list of green countries is short and includes some pretty obscure destinations (no offence, Tristan da Cunha). Among European countries, only Iceland is on the green list after Portugal was removed.
