The Foreign & Commonwealth Development Office (FCDO) does not have a definition of what they class as 'essential travel'. The FCDO website states (https://www.gov.uk/guidance/how-the-foreign-commonwealth-office-puts-together-travel-advice):
"Sometimes we say that only essential travel is advised. Whether travel is essential or not is your own decision. You may have urgent family or business commitments to attend to. Circumstances differ from person to person. Only you can make an informed decision based on the risks."
Holiday Extras will only cover a destination classified as 'all but essential travel' if the customers have contacted us with their reasons for travel and cover has been agreed by our Underwriters, Travel Insurance Facilities (TIF), where possible prior to travelling.
